  • Robots are being applied in increasing numbers for some applications, for example urban logistics and transport belongings. New types of personal following robots are used nowadays inside office buildings, shopping malls or outdoors to provide assistance to carry heavy loads or to help persons with limited mobility capabilities. In shopping malls, it is known to use flat or inclining moving walkways and escalators as main transportation systems for people due to their high transport capacity.
  • the aforementioned generation of robots has to share the space with persons and interact with the escalators/moving walkways following the best trajectories and reaching the best positioning at every moment.
  • the technical environment may comprise a method, a system, a robot, a computer program, a data carrier signal and/or a computer-readable medium to solve the aforementioned object.

  • the method comprises at least the following steps:
  • robot transport data with at least one of the following:
  • sequence of method steps can be varied, unless technically required in an explicit order. However, the aforementioned sequence of method steps is particularly preferred.
  • first environmental data are detected.
  • This environmental data is then used to generate respectively determine the robot transport data.
  • the robot transport data should comprise at least one of the measures mentioned in this context, which are: determining the trajectory for the robot, the robot properties, the selected pallet of the transportation means on which the robot should move and/or the conveyor speed of the transportation means.
  • the common move-on speed can be determined. This common move-on speed is used to ensure that the robot can move onto the transportation means without swinging or tilting.
  • the robot brakes and the movement of the autonomous robot is completed.
  • the robot moves off the selected pallet.
  • the method steps are applied analogously as far as possible.
  • the conveying speed of the transportation means, and the robot movement speed of the robot are coordinated.
  • the transportation means in the following paragraphs are escalators and moving walkways. In principle, the explanations also apply to analog transportation means.
  • An escalator or moving walkway preferably communicates with the robot to indicate the best trajectory to enter the respective escalator/moving walkway, the best position on the pallet and the best route to exit the escalator/moving walkway.
  • An escalator or moving walkway preferably interacts with any kind of robot including autonomous and follow-people robot to send the synchronization data to enter and exit and to avoid obstructing the transit of persons. In these cases, it is important that both, the escalator/moving walkway and the robot, have information about the next action to deploy a better performance.
  • the escalator/moving walkway performs some kind of interaction with the robot. Firstly, robot and persons around can be detected to set a predefined trajectory to enter the escalator/moving walkway. This trajectory can be predefined by the initial setup of the robot, or modified in real time by the escalator/moving walkway, for example according to the free space and/or to the people flow in each moment. A further measure is to know the conveyor speed of the escalator/moving walkway and the type of the robot. With this information, the synchronization of the speed of both systems can be performed to avoid unnecessary stops when the robot approaches the escalator/moving walkway.
  • the required space is variable and specific to each robot model.
  • the escalator/moving walkway can detect the type of the robot and the dimensions via the detection system and the computing system to estimate if it is possible to use the escalator/moving walkway according the characteristics of both systems, namely the escalator/moving walkway and the robot.
  • Preferred robots may comprise sensors that enable the possibility of interaction with persons.
  • the robot can share the space with people in a flexible way, whereas the escalator/moving walkway operations follow a continuous, unchangeable process. For example, if a robot is to enter the escalator/moving walkway and there is one person standing between the robot and the escalator/moving walkway, the robot has to stop and it needs to wait until the person enters the escalator/moving walkway. It is important to achieve a common move-on speed for the robot and the escalator/moving walkway. Otherwise, due to the limited distance to the next pallet, the robot would have to accelerate very quickly to adapt to the conveyor speed of the escalator/moving walkway.
  • the arrangement for executing the method comprises: the transportation means, that preferably moves passenger(s) and/or robot(s) between floors; an entry area as the claimed stationary underground, wherein the entry area is positioned adjacent to the entry of the transportation means, and an exit area, which is analog stationary to the stationary underground of the entry area, and which is positioned at the exit of the transportation means, wherein the robot moves onto the pallet of the transportation means from the entry area, and wherein the robot moves off the same pallet after its transport into the exit area; the detection system, which can comprise cameras and/or other sensors, that are configured to monitor, i.e.
  • the monitoring takes place in the transition area from the stationary underground of the entry area to the selected pallet and/or from the selected pallet to the corresponding stationary underground of the exit area; preferably an additional sensor for the transportation means, if necessary, to synchronize the step position with the movement of the robot.
  • an additional sensor for the transportation means if necessary, to synchronize the step position with the movement of the robot.
  • this can be preferred, in case that the system is not capable to perform the calculation; a computing system, preferably with at least one processor, in charge:
  • the computing system only performs one or some of these aspects.
  • same computing system is, also in charge of interchange information with a controller of the transportation means in order to control speed changes and/or to receive transportation means status date, like its conveyor speed or its moving direction.
  • the system comprises the detection system, which for example comprises a set of cameras and/or other sensors, that monitor the entry and/or exit areas of the transportation means and is connected to a computing system that is continuously checking the presence of robots, the free space and distance in the monitor areas and measuring the conveyor speed of the transporting means and the robot movement speed of the robot.
  • the system is connected to the controller of the transporting means to send/receive the necessary information to control the movement of the transporting means. If necessary, for example, an additional sensor can be considered for escalators to check the step position and allow the synchronization between the robot and the step.
  • Detecting environmental data, by the detection system, of movable units on the stationary underground, which is adjacent to the transportation means, means in particular that the environment of the transportation means is monitored for persons or persons carrying objects that want to use the transportation means or that are at least in its immediate vicinity and are therefore potential obstacles for a robot that wants to use the transportation means.
  • the detection system can be an integral part of the transportation system.
  • the detection system can be a part of a separate system.
  • the detection system can be a separate system itself.
  • the detection system can be exchanged or upgraded on demand.
  • the computing system can determine the robot transport data with one or more measures to ensure that the robot can safely move onto the transportation system. If several measures are combined, the overall safety of the robot's movement can be increased.
  • Determining, by a computing system, the trajectory for the robot means in particular that a trajectory is determined that allows the robot to safely move onto the transportation system.
  • the formulation safely means that the trajectory keeps the robot away from potential collision obstacles. It is not excluded that this trajectory determination is combined with other measures, such as the determination of the robot properties. If, for example, a technically induced maximum acceleration is determined, the trajectory can be modified accordingly. For example, the trajectory may be a bit longer so that the robot has more distance to accelerate, so that the common move-on speed can be achieved.
  • This criterion can be the only criterion for the robot to stop in its waiting position. Preferably, this criterion can be combined with other criteria.
  • Determining, by a computing system, the robot properties means in particular that one information or several different data of the robot can be determined. These robot properties can, for example, be communicated by the robot itself to the computing system. Alternatively or additionally, the robot properties can be derived from a specific robot type. For example, a model name can generate a database request, so that technical data of the robot can be obtained, which can be used for synchronization to the common move-on speed. For example, an identified respectively determined maximum speed and acceleration of the robot can be below the standard conveyor speed and acceleration of the transportation system. Thus, for example, the conveyor speed of the transportation system and/or the trajectory of the robot can be determined on the basis of these robot properties in such a way that the robot can safely move onto the transportation system.
  • model name can also be obtained by means of the model name, such as the dimensions of the robot.
  • the model name can be detected by the detection system and subsequently interpreted respectively determined or, for example, derived from the contour of the robot by a qualified computing system.
  • the computing system can either be fed directly with the information or be actively involved in its derivation.
  • This criterion can be the only criterion for the robot to stop in its waiting position. Preferably, this criterion can be combined with other criteria.
  • the subsequent synchronization to the common move-on speed can be performed in such a way that the robot moves with such a robot movement speed and/or trajectory onto the selected pallet of the transportation means with an adequate conveyor speed that the robot stands on the one selected pallet for transportation by the transportation means without swinging or even tilting.
  • This criterion can be the only criterion for the robot to stop in its waiting position.
  • this criterion can be combined with other criteria.
  • the conveyor speed of the transportation means means in particular that a safe movement by the robot onto the transportation means can be supported.
  • the subsequent synchronization to the common move-on speed can be performed in such a way that the robot moves with such a robot movement speed and/or trajectory onto a selected pallet of the transportation means with an adequate conveyor speed that the robot stands on the one selected pallet for transportation by the transportation means without swinging or even tilting.
  • This criterion can be the only criterion for the robot to stop in its waiting position.
  • this criterion can be combined with other criteria.
  • Robot transport data includes those aspects that are relevant for safe move-on.
  • the formulation robot transport data can also be understood as robot movement data.
  • the common move-on speed can be determined preferably considering all relevant aspects. This common move-on speed can be used next to set the robot movement speed and/or the conveyor speed. This is also understood as synchronizing the conveyor speed of the transportation means and the robot movement speed to the common move-on speed.
  • Synchronizing the conveyor speed of the transportation means and the robot movement speed to the common move-on speed means in particular that, in a next step, the robot can safely move along the stationary underground with a robot movement speed onto the transportation means, whereby the robot movement speed and the conveyor speed are coordinated with each other.
  • both speeds are practically the same.
  • the value of the speed preferably depends on the transportation means and robot features in a way that allow to be the same once the move on process finishes. Preferably, this means that they differ from one another by no more than including ten percent, especially preferred by no more than including five percent.
  • the robot movement speed is lower than the conveyor speed because the robot moves onto the pallet at its robot movement speed and in this context it is particularly important to avoid the robot hitting a step or a movable unit with its front side due to too much thrust.
  • Moving the robot onto the selected pallet means in particular that the robot drives onto the selected pallet in such a way that any slippage or similar disturbing factors are avoided.
  • the robot moves with the common move-on speed on the transportation means. This means that the robot is neither slowed down nor is the robot pulled by the pallet that is at least partially occupied by the robot. Thus, tipping in and against the direction of the conveyor speed is avoided by setting the common move-on speed.
  • Braking of the robot on the selected pallet means in particular that the robot should stand on the selected pallet in such a way that it has a secure footing for transport. It is also preferable to consider the robot's center of gravity.
  • the exit area is only detected if the transportation means actually transports a robot. This has proven to be energy-saving and therefore environmentally friendly.
  • the transportation means is an escalator or a moving walkway.
  • An escalator is a passenger transportation means for overcoming a height distance, in which moving pallets form steps.
  • An escalator is a transportation means, with at least one pallet, each pallet is exemplary partially horizontally and partially vertically movable. The purpose is generally to transport people at a speed higher than walking speed and/or with less muscle power.
  • a further simplification is that a robot, for example, follows a person and transports their purchases. Accelerated transport of people and their robots from/to a location can save time and space (e.g. on platforms or in department stores).
  • a moving walkway is a transportation means, with at least one pallet, each pallet being movable horizontally to the ground, whereby the moving walkway can also extend over a slope.
  • the movable units comprise the robot, external robots and/or living beings, in particular persons. It is therefore a very careful device that takes into account both people and the robot to be transported by the transportation means. It is therefore a very careful device that takes into account both people and the robot to be transported by the transportation means. The risk of collisions can be further reduced by taking into account external robots.
  • pets, especially dogs can be considered as living beings, which are detected as movable units.
  • the determining the trajectory takes a predetermined trajectory into account; and/or the environmental data into account, wherein preferably living beings are prioritized in such a way that, if possible, they are not affected by the movement of the robot.
  • the predetermined trajectory means that there can be a standard trajectory for each robot or for each transportation means. This predetermined trajectory can be used without any change. The predetermined trajectory can be useful to save computing capacity or if the trajectory is specifically designed for the requirements of the type of robot.
  • the predetermined trajectory can be modified by taking the environmental data into account. For example, if the predetermined trajectory is obstructed by a temporary flower box, this is detected from the environment data and the trajectory is adjusted accordingly.
  • the computing system or the robot itself determines a waiting position for the robot, in such a way that, if possible, living beings are not affected by the waiting position of the robot. In this way it can be avoided that living beings that want to use the transportation means are affected by the robot. This is especially advantageous if the robot does not follow a human being but travels autonomously without time constraints. If the robot is following a human, it may be necessary to consider whether the robot, depending on its load, should actually be distanced from the human or whether it should take the waiting position so that a prioritization of the following can be set. For example, if high value goods are transported, the robot might not wait in the waiting position and might stay close to the human it is following. For example, if the robot is travelling alone without a load, it might be preferred that it takes the waiting position.
  • a stop command is sent to the robot to keep it in its waiting position, if the computing system determines inter alia that: the robot has not sufficient distance to a front movable unit, if present; there is not enough space for the robot to enter the transportation means; the original pallet to be moved onto is occupied and/or not passable; and/or there is not enough distance between the robot and the pallet to be moved onto, to achieve the required common move-on speed to move the robot safely on the transportation means.
  • Other constellations are also possible for sending a stop command to the robot, for example if in any situation the robot using the transportation means could represent a risk for the living beings/persons, the robot and/or the transportation means.
  • This criterion can be the only criterion for the robot to stop in its waiting position. Preferably, this criterion can be combined with other criteria.
  • the fact that the robot stops if there is not enough space for the robot to enter the transportation means means that neither the robot nor the transportation means will be damaged by pushing the robot through.
  • the situation can be solved by removing any movable obstacles or by moving the robot to enter the transportation means in another position.
  • This criterion can be the only criterion for the robot to stop in its waiting position.
  • this criterion can be combined with other criteria.
  • the fact that the robot stops if the original pallet to be moved onto is occupied and/or not passable means that the robot reduces the risk of an accident. For example, the pallet may be occupied by a pet that would otherwise be hit by a car. Such accidents can be avoided.
  • This criterion can be the only criterion for the robot to stop in its waiting position. Preferably, this criterion can be combined with other criteria.
  • the fact that the robot stops when there is not enough distance between the robot and the pallet to be moved onto, to achieve the required common move-on speed to move the robot safely on the transportation means that the robot reduces the risk of an accident.
  • the robot may not be able to accelerate to sufficient speed because the acceleration distance is too short, so that the robot is not completely on the selected pallet. If the pallet is an escalator pallet and the robot is not completely on the selected pallet, the robot would tip over when the pallet becomes a vertical step.
  • This criterion can be the only criterion for the robot to stop in its waiting position. Preferably, this criterion can be combined with other criteria.
  • steps of the method are repeated at least partially, wherein optionally the robot is repositioned in advance.
  • steps of the method are at least partially repeated leads to the fact that the method is to be finally completed. It is preferable to repeat only as many steps as necessary to save computing capacity.
  • the method can be completely repeated. Repositioning leads to the creation of possibly more favorable starting conditions for executing the method.
  • the trajectory can be distanced from an originally undetected obstacle.
