Definitions
- the invention relates to an autonomous robot provided with a multispectral sensor.
- the invention finds particular application in the agricultural field, and in particular precision agriculture.
- Such robots are used in particular to establish and share a mapping of plots of land in order to carry out a diagnosis of the plot.
- Autonomous robots are currently used in agriculture to detect the nutritional needs of plants within a plot as well as the presence of pests such as weeds, diseases or pests.
- the robots are equipped with detectors or imagers making it possible to carry out a diagnosis of the plot in the form of mapping, in order to allow the farmer to carry out precision interventions and to save on inputs and limit the impact on the environment while increasing the productivity of the crops in place.
- drones equipped with multispectral imaging devices are known. These remotely piloted drones fly over agricultural plots to collect data and generate maps relating to the state of agricultural crops overflown.
- Document WO 2014/111387 also discloses an automated agricultural robot making it possible to collect precision agricultural data comprising displacement optimization means for moving non-randomly between the rows of plantation.
- Robots configured to carry out maps of agricultural plots are also presented in document RU 2633 431.
- the configuration of these robots leads to a deterioration of the crops which they pass through.

- Document WO 2006/063314 also describes a robot equipped with sensors for measuring parameters of the plot. However, the size and bulkiness of these robots also cause crop deterioration as they pass.
- Document WO 2019/040866 describes an autonomous robot for phenotyping the terrain comprising a multispectral sensor, designed to avoid damaging the plantations.
- the mode of implementation described in the document proposes a robot comprising four wheels, which is only suitable for row crops, in particular corn, between which it can move.
- this robot is not suitable for crops that are not in a row in which it necessarily causes crop damage.
- the object of the present invention is therefore to remedy the drawbacks of the prior art, by proposing an autonomous robot capable of scanning a plot completely with a view to carrying out a diagnosis, which is suitable for numerous types and phenological stages of crops, especially for crops that are not in row, by limiting as much as possible its impact on the crops.

- a stabilization device to control the pitch of the elongated body when the wheels are in motion.
- the wheels consist of spoked wheels.
- Such a robot therefore has the advantage, compared to robots of the state of the art, of having only two wheels, which makes it possible to limit the impact on the crops as it passes as much as possible. This impact is all the less great as the shape of the wheels, in spokes, makes it possible to minimize the contact surface between the robot and the ground and allows the robot to step over the plants without laying them down.
- the imbalance generated by the two-wheel limitation is compensated by the presence of the stabilization device.
- the elongated body has a substantially parallelepipedal or cylindrical shape, with an axis transverse to the direction of movement of the robot;

- the energy storage means are integrated in a sealed box provided with a cover and fixed to the elongated body;
- the autonomous robot has a direction of movement in the direction of movement, and a center of gravity located at the rear of the transverse axis with respect to the direction of movement;
- the stabilization device is formed of a cane
- the cane is a curved cane comprising a rectilinear proximal part and a curved distal part, the proximal part being connected to the elongated body, the distal part being intended to be in contact with the ground when the wheels are in motion; - the distal part of the cane includes a camera;
- the cane is a rotating cane around the axis of the proximal part
- the stabilization device comprises means for moving the center of gravity of the autonomous robot on either side of the transverse axis;
- the stabilization device is formed of a rack-and-pinion system allowing the displacement of the rack in the direction of movement of the robot, the pinion being fixed to the elongated body, the rack being formed of an elongated rod;

- Such a robot 1 can in particular be used in the agricultural field to collect data from an agricultural plot.
- it can be data making it possible to characterize the nutritional needs of the plants in the plot, or to detect the presence of pests (weeds, diseases, pests, etc.) within the plot.
- autonomous is meant in this description that the robot 1 is able to perform a certain number of automated tasks without requiring human, physical or remote-controlled intervention.
- the robot can in particular be programmed to move alone within a plot, and to find its way, for example by means of an integrated geolocation system, so as not to exceed the perimeter of this plot.
- the robot can also be programmed to locate itself in relation to surrounding objects and to avoid collisions, for example with other robots, humans or vehicles. For this purpose, it can include proximity sensors of sonar, lidar or other well known instruments. It can also be programmed to collect data at regular time intervals.
- the autonomous robot 1 is provided with an on-board computer system 2, visible in FIG. 2, comprising in particular a processor, a memory unit, and all the other computer resources making it capable of interpreting and executing instructions which can be used. have been pre-established by the user.
- an on-board computer system 2 and such instructions are customary for those skilled in the art and will not be developed in this description.
- the autonomous robot 1 is designed to minimize the impact of its passage on crops and to travel long distances, typically covering 20 hectares per day, while benefiting from sufficient stability to carry out the instructions on all terrains.
- the autonomous robot 1 has a low mass, advantageously less than 20 kilograms, or even less than 15 kilograms or even 10 kilograms.
- a low mass has the advantage of limit both plant damage and soil compaction, responsible for smothering microbial life.
- an autonomous robot 1 according to the invention comprises an elongated body 3 along an axis transverse to a direction of movement of the robot 1.
- the elongated body 3 has a substantially parallelepipedal or cylindrical shape, the axis of which is the axis transverse to the direction of movement, in order to minimize its volume and its bulk.
- the robot 1 also comprises, connected to the elongated body 3, two wheels 4 arranged on either side of the elongated body 3 along the transverse axis.
- the robot 1 comprises exactly two wheels, that is to say it does not have a third wheel or additional wheels liable to increase the deterioration of the ground as it passes.
- the wheels 4 consist of spoked wheels.
- a spoke wheel consists of a hub 4a directly connected to the elongate body 3, a plurality of spokes 4b fixed to the hub 4a and extending radially from the hub 4a.
- the spoked wheel 4 is devoid of any element joining the spokes 4b with the exception of the hub 4a, such as a strapping or a tire.
- This form of wheel 4 is advantageous over the wheels usually described in the documents of the state of the art in that they limit the contact surface between the robot and the ground and avoid laying the plants under the passage of the robot. , the rays spanning the plants when robot 1 is in motion.
- the number of spokes 4b can be variable, and can advantageously be between six and twenty, advantageously eight, ten or twelve spokes.
- the size of the shelves 4b can be adjusted according to the needs and the nature of the plot, and can advantageously be between 20 cm and 1 meter.
- All the spokes 4b can be of the same size in order to give a generally circular shape to the wheel 4. However, such a choice is in no way limiting of the invention, and it may appear advantageous to provide spokes 4b of different size. from each other, for example by alternating a longer spoke and a shorter one, in order to give a different shape to the wheel 4.
- the number and size of the combs 4b determine the space between two points of contact with the soil as well as the spanning of the plants. They can thus be adjusted according to the user's needs and the nature of the plot and the plants, as well as the phenological stage of the crop in progress on the plot. This gives the robot 1 significant modularity as well as great adaptability to different types of terrain.
- each spoke 4 can be provided with a shoe 4c to reduce the impact of the wheel 4 on the ground.
- Such pads 4c are thus shaped to minimize their sinking into loose soil, as shown in Figures la to le. It is also possible to provide more sophisticated pads, such as those described in document WO 94/20313.
- the size of the pads 4c is also preferably chosen to limit the contact surface with the ground while avoiding to sink into the ground.
- the surface of the pads may be between 10 and 20 cm 2, for example with a width of 2 cm for a length of 6 cm.
- the material for forming the spokes 4b is advantageously chosen from lightweight and inexpensive materials, for example carbon fiber, glass fiber or, preferably, aluminum.
- the material is also relatively flexible, such as aluminum, for example, in order to absorb and dampen the shocks associated with crossing obstacles. Such flexibility thus makes it possible to avoid the risk of the spoke bending or breaking as a result of an impact.
- FIG. 2 represents an isometric perspective view of the interior of the elongated body 3 according to a preferred embodiment of the invention.
- the robot 1 can include a motor 5 configured to set the wheels 4 in motion. When it advances, the robot 1 thus moves in a direction of movement, in a direction of movement.
- the motor can be integrated into the elongated body 3, as can be seen in FIG. 2, which allows the motor 5 to be protected from external attacks (water, dust, etc.)
- the on-board computer system 2 is also integrated into the elongated body 3, it can be electrically connected to the motor 5 in order to provide it with instructions relating to the setting in motion of the wheels 4.
- the invention is in no way limited to such configurations, and the motor 5 can be placed outside the elongated body 5, and can for example be fixed to the wheel 4.
- the robot 1 can contain a single motor 5, which simultaneously drives the two wheels 4.
- the robot 1 comprises two motors 5, each motor 5 being associated with a wheel 4.
- the two motors 5 can drive independently.
- the wheels 4 Such a configuration is of particular interest in particular for allowing the robot 1 to make a turn, since it is then possible to block a wheel 4 while continuing to advance the other wheel 4, the first wheel serving pivot around which the robot will rotate 1. It is also possible for the robot 1 to make a U-turn on itself, since it is possible to rotate a wheel 4 in one direction while rotating the other wheel 4 in the other direction. Such a possibility allows the robot 1 to occupy a minimum of space to change direction, which is particularly useful in the case of crops which are not in a row.
- the robot 1 can also include energy storage means 6, such as a battery. It may in particular be a lead battery, a nickel battery, or a lithium battery.
- the battery 6 can advantageously be integrated into a sealed box 7 provided with a cover 7a allowing access to the battery 6, the sealed box 7 being fixed to the elongated body 3. Alternatively, the battery 6 can also itself form the battery. cover 7a.
- the sealed box 7 is fixed to the rear of the elongated body 3 in the direction of movement, in order to shift the center of gravity of the robot 1 behind the transverse axis relative to the direction of movement. The advantage of such a characteristic will be developed in the remainder of the description.
- the battery 6 makes it possible to supply the entire electrical system, and in particular the on-board computer system 2 and the engine (s) 5 with electricity.
- the robot 1 can be fitted with photovoltaic panels (not shown in the figures) to supply electrical energy to the battery 6 and to recharge it, and to make it possible to increase the autonomy and the operating time of the robot 1.
- photovoltaic panels can be placed on the elongated body 3, on the sealed box 7 or on a central zone outside the wheels 4.
- the robot 1 can also include a switch 8, placed outside the elongated body 3 and connected to the on-board computer system 2, making it possible to turn the latter on or off or more generally to interact with the electrical elements.
- the robot 1 may include a battery monitoring system (more usually referred to by the term BMS, acronym for the English term “Battery management System”) making it possible to display the state of charge of the battery, or more generally the operating state of the device.
- BMS Battery management System
- This system may have an interface in the form of a display system, for example of the LED or LCD type. Stabilization device
- the autonomous robot 1 also comprises a stabilization device 9 for controlling the pitch of the elongated body 3 when the wheels 4 are in motion.
- the center of gravity of the autonomous robot 1 is kept fixed behind the transverse axis with respect to the direction of movement, for example by means of the fixing of the box. waterproof 7 at the back of the elongated body 3.
- the stabilization device 9 is a passive stabilization device formed of a rod.
- the rod 9 is preferably disposed at the rear of the elongated body 3, for example integrally attached to the waterproof box 7, and is intended to touch the ground when the robot 1 is in motion. In this way, the rod 9 opposes the torque created by the motor (s) 5 and makes it possible to block the elongated body 3 according to a determined pitch angle, imposing the rotation of the wheels 4 and preventing the elongated body 3 from turning on itself.
- the rod 9 is a curved rod comprising a rectilinear proximal part 9a and a curved distal part 9b, that is to say the end of which is oriented and raised upwards as this is clearly visible in figure lb.
- the proximal part 9a is connected to the elongated body 3, preferably integrally attached to the sealed box 7.
- the distal part 9b is intended to be in contact with the ground, in particular when the wheels 4 are in motion.
- the curved aspect of the part of the cane in contact with the ground makes it possible to limit its impact on the crops, and not to catch, scratch or tear the plants crossed by the robot 1.
- this curved shape makes it possible to prevent the rod 9 from sinking into the ground, the contact surface with the ground of the distal end 9b increasing when the latter begins to sink therein. This property is very advantageously, in particular when the soil is loose, which is frequently the case with agricultural plots.
- the distal part of the rod at least at the level of the curved section, has an oval or circular section in order to form a point contact (when the ground is rigid) and to slide better over obstacles.
- the low weight of the robot 1 makes it possible to prevent the rod 9 from creating furrows on the ground, which would have been more the case with a third wheel.
- the presence of a cane also makes it possible to eliminate the phenomena of bogging down observed with the use of an additional wheel.
- the rod 9 is a rotary rod, capable of pivoting about the axis formed by the part. rectilinear proximal 9a of the rod 9.
- the rod 9 is not rigid during the movement of the robot 1, and can follow the movement of the latter, in particular when it makes turns, without marking the ground.
- the rod 9 can thus pivot freely on itself when it encounters an obstacle or when the robot 1 makes a turn instead of sliding and / or translating rigidly with the movement of the robot by mowing any plants present in its vicinity. . Stops can be provided making it possible to limit the angular movement of the rod.
- the rotation of the rod 9 can be controlled by the on-board computer system 2 in order to control the position of the rod 9, as will be detailed in the remainder of this description.
- the proximal part 9a can be fixed perpendicularly to the sealed casing 7 and maintained substantially vertical when the robot 1 is in motion, in order to guarantee a substantially horizontal maintenance of the casing 7 and of the elongated body 3, protecting the elements integrated inside it. too great a pitch angle and amplitude.
- the proximal part 9a can also be tilted backwards in the direction of movement in order to soften the contact between the distal part 9b and the ground, the angle between the proximal part 9a and the elongated body 3 having to be close to 90 ° so as not to force excessively on the connecting parts, such as ball bearings in particular, between the sealed housing 7 and the rod 9.
- the stabilization device 9 is an active stabilization device, comprising means for moving the center of gravity of the autonomous robot 1 on either side of the transverse axis, in the direction of travel.
- This embodiment makes it possible to adjust at any time the position of the center of gravity of the robot 1 relative to the elongated body 3, in order to control the pitch of the latter.
- the stabilization device 9 can move the center of gravity away from the transverse axis in the direction of movement to unbalance the robot 1 and allow it to move. Once set in motion, the center of gravity is reestablished backwards, towards the transverse axis, to find a new balance.
- the stabilization device 9 forms the counterweight necessary for the spokes 4b to take the step, the dynamic offset of the counterweight allowing the setting in motion.
- the center of gravity thus oscillates permanently between the front of the robot 1 in the direction of movement, to allow it to move forward, and the rear of the robot 1 in order to limit its runaway.
- the offset of the counterweight towards the rear of the robot in the usual direction of movement of the robot 1, combined with a change in the direction of rotation of the wheels 4 controlled by the motor (s) 5, can also make it possible to operate a setting in motion of the robot 1 in the opposite direction. This operation allows the robot 1 to reverse on the same line, without having to make a turn, in order to reverse its direction of movement.
- the stabilization device 9 is formed by a pinion-rack system 9 allowing the movement of the rack in the direction of movement of the robot 1.
- the pinion is fixed to the elongated body 3.
- the rack is formed of an elongated rod forming a counterweight.
- the movement of the rack along the direction of movement of the robot 1 makes it possible to control the offset of the counterweight and the distance of the center of gravity from the transverse axis of the elongated body 3.
- This movement can be mechanical in order to maintain a position of equilibrium and to keep the body stretched out in a determined pitch angle. But this movement can also be automated, the movement of the rack being controlled by the on-board computer system 2, either according to pre-established instructions, or according to the parameters of the situation.
- the on-board computer system 2 can be instructed to control a slight imbalance of the elongated body 3 when it is set in motion and then a dynamic balance during the movement. This dynamic balance can in particular take into account the irregularities of the terrain or the slopes liable to unbalance the robot 1.
- the on-board computer system 2 can be associated with an inertial unit (not shown), consisting of an inclinometer, d 'an accelerometer and / or a gyroscope, and attached to the elongated body 3.
- the autonomous robot 1 is intended to collect data from the environment which surrounds it, for example to detect the presence of weeds or insects, or to capture the radiation emitted by the plants.
- the analysis of the radiation emitted by the plants makes it possible to monitor the nutritional needs of the plant, in particular the water need and the nitrogen content. This last aspect is in particular known from document WO 99/19824 and will not be developed in more detail in the present description.
- the autonomous robot 1 comprises at least one multispectral sensor 10.
- This multispectral sensor 10 can be placed inside the elongated body 3, and can be connected to the on-board computer system 2 to receive instructions and to the battery 6 to be electrically powered.
- the multispectral sensor 10 is placed on a lower face of the elongated body 3 in order to be able to analyze the canopy that it overhangs.
- the invention is in no way limited to such a location.
- the robot 1 can include a plurality of multispectral sensors.
- the autonomous robot 1 can also include other data collection instruments, such as visible or infrared cameras. Cameras can thus be integrated in the elongated body 3, in the waterproof case 7, or even attached to one of the spokes 4b.
- the stabilization device 9 is formed by a curved rod
- the distal part 9b of the rod 9, and more particularly its free end can also include a camera 9c.
- This location makes it possible to have a camera very close to the ground and oriented upwards, and thus to collect data from below the canopy.
- the rotary nature of the rod 9 allows, if it is commanded by the on-board computer system 2, to carry out a very broad exploration of the environment around the robot 1.
- the distal part 9b of the rod 9 can also include an LED or other light source in order to illuminate the underside of the canopy to improve the quality of the images acquired by the camera 9c, for example by reducing any effects. shade.
- the robot 1 can also include a device for recording the data collected by the data collection instruments.
- This recording device can be integrated into the elongated body 3 and coupled to the on-board computer system 2 to receive the recording instructions.
- the recording device can be, or be associated with, a removable recording card, such as an SD card for example, that the user can remove from the robot 1 to recover the data collected and analyze them, or directly recover. data analyzed by a data analysis device.
- the robot 1 can therefore also include a data analysis device, coupled to the recording device or to the on-board computer system 2, making it possible to analyze the data collected and recorded and to record the analysis carried out on the device. recording.
- the recording device can include remote communication means using radio frequencies, such as Bluetooth®, Wi-Fi TM, 2G, 3G, 4G, 4G +, 5G, ZigBee TM, LoRa® means. and / or Sigfox TM for example, in order to be able to remotely transmit to the user the data collected or the data analyzed.
- radio frequencies such as Bluetooth®, Wi-Fi TM, 2G, 3G, 4G, 4G +, 5G, ZigBee TM, LoRa® means. and / or Sigfox TM for example
- the invention is not limited to the embodiments of the stabilization devices described. It is quite possible to envisage stabilization devices other than a rod or a rack and pinion system, such as an active gyroscope or a balance for example.
