This is a surprising obstacle avoidance car, because it does not use any micro controller units but simply with a mechanical system to achieve avoiding obstacles automatically.
Trigger endstop switch to realise automatic steering through reversing the motor. Someone who like to do it by yourself, never miss it! Moreover, there is no programming required, which is more suitable for those who don’t know how to program. And please pay attention to that it also can not be programmed for a secondary development.
