The diagram below shows an old BEAMBot strategy:
Is there code or an example using this method? I would rather avoid OpenCV, ultrasonic, GPS etc. I just want the Roomba wheels to react as I go straight, turn left or right. Finally, I could add a front wheel on a servo and try having the Roomba turn with me.
Also has anybody added big, all terrain wheels to a Roomba to replace the originals?
