So how do we control?
We have seen that motor speed is affected by friction and by whether the robot is travelling up or down a slope – and thus to maintain constant speed, feedback and control are needed.
But precisely how do we control the robot? In the video above, Richard explains how a human can attempt to control the speed, and then shows how it can be done automatically. The video features a web page showing a robot on a simple hill but it also supports other ‘landscapes’. You now have the opportunity to investigate the control strategies on the different landscapes.
If you’re interested in the speed control demo mentioned in this video – you can try the Robot Moving on Different Surfaces Web Page yourself.
