Angle displacement sensor:！

Angle displacement sensor:
Angle displacement sensor applied to the obstacle treatment: the use of angle sensors to control your wheels can be an indirect obstacle. The principle is very simple: if the motor angle sensor structure is running, and the gear does not turn, indicating that your machine has been blocked by the obstacles. This technique is very simple to use and very effective; the only requirement is that the wheels of the movement can not slip on the floor (or slip too many times), otherwise you will not be able to detect obstacles. An idle gear is connected to the motor to avoid this problem, which is not driven by the motor but is driven by the movement of the device: if the idler is stopped during the rotation of the drive wheel, it means that you have obstructed
