Definitions
- the invention relates to a drone with a special Mon days of sensors and methods.
- Standard sensors that come into question for this are, for example, lidar, radar, infrared, ultrasound, etc.
- the sensors can crosstalk, i.e. the signal sent by one sensor can be detected by another after multiple reflections and incorrectly evaluated as a useful signal, which leads to uncontrolled behavior of the drone.
- GPS-based drones For outdoor use, there are GPS-based drones that cover predetermined routes in a controlled manner using predetermined waypoints in combination with ultrasonic sensors and barometers. to fly. Above a certain height above obstacles, the probability of a collision is low. Therefore, a complete survey of the surroundings is avoided.
- the cage is heavy and thus shortens the possible service life considerably.
- the object is solved by a drone according to claim 1 and a method according to claim 2.
- Figure 1 shows a drone according to the prior art
- Figure 2 shows a servo for a drone according to the invention
- these sensors 13, 13′, 13′′ are mounted on a commercially available pan-tilt servo 90 (FIG. 2), such as is usually used for image stabilization of cameras.
- This pan-tilt servo 90 is extremely easy to implement using commercially available micro-servos.
- Any sensor for detecting distances can be used as a sensor, ie in particular lidar, radar, infrared or ultrasound.
- This construction enables a sensor 13 to be directed freely along a hemisphere.
- the target flight direction of the drone 200', 200'' is known at all times, it results from the combination of the control axes pitch, roll, yaw, yaw and throttle.
- the resulting motion vector can easily be calculated from these four control axes. This is the case at least at low speeds, since flight dynamics and wind resistance play a subordinate role.
- An inspection drone usually moves at walking speed.
- the target movement vector is immediately taken over by the pan-tilt mechanism, directing one of the drone's two distance sensors to the area to be flown in the future. With positive throttle input (climb) only the upper sensor is active, with descent only the lower one. This rules out any crosstalk from the sensors 13 .
- FIG. 2 shows a servo 90 according to the pan-tilt mechanism.
- This servo 90 has a base 4 .
- the base 4 can be mounted on any body or torso 80.
- a first joint 7 connects to the base 4 and can rotate and tilt a first rotary body 9 about a longitudinal axis 11 .
- a second joint or axle 10 is present on this first rotary body 9 .
- a bracket 12 in particular is moved by the second joint or axle 10 in the form of an axle.
- the bracket 12 is particularly U-shaped here.
- a sensor 13 is present.
- two such servos 90 are used to control the drone 200', 200''.
- FIG. 3 shows a drone 200' according to the invention.
- the drone 200' has a fuselage 80 with known propellers 40 or drive means 40 and in a known and necessary number, in particular 4 propellers.
- the shape of the hull 80 is shown only schematically.
- the arrangement of the drive means is only shown schematically here, i.e. they can be arranged on the underside 82 or at the height of the fuselage 80, on the side surfaces 83, 84, ....
- a servo 90′, 90′′ according to FIG. 2 is arranged on the upper side 81 and on the underside 82 of the fuselage 80, each servo having a sensor 13′, 13′′.
- FIG. 4 shows another drone 200'' based on FIG.
- a camera 50 is present on both drones 200', 200'' on the top 81 and/or bottom 82.
