3.9 Concept Development

(21.03.22) The concept is is to supply the drone with energy from the ground. For this, a cable will be connected to the battery on the drone and to a reel on the ground, then connected through a sliding contact with a power generator to send the energy.

(03.11.21) The basic idea is to integrate an energy-efficient ESP32 into the free space inside the pedal. Controlled by the ESP32, an electric motor should then drive a winch to wind up the rope. The unwinding of the rope is to take place with minimal mechanical resistance. For this purpose, either a mechanical freewheel is used between the winch and the motor output shaft, or a torque-free motor operation is used in this direction of rotation.
