The car drives and turns in order to avoid surface contact. When it encounters a surface that is less than the stopThreshold the car stops and turns to measure distances to it’s left and right. It then compare these readings and drives in the direction with most space.
As seen in the video the car drives and turns in order to avoid surface contact. When it encounters a surface that is less than the stopThreshold (see code snippet below) the car stops and turns to measure distances to it’s left and right. It then compares these readings and drives in the direction with most space available.
