News about Dr Bürhool the Hooverbot

The project is progressing slooowly as a humanoid-project titled “Aüduhn” takes most of my time. humanoid
Anyway, the bot IS developing and now features motorized wheels, servo head movement, animated eyes and a web cam. Camera and control is done trough WiFi connection. Bleeping sounds will come. Probably also some doomsday device to help him enslave humanity. Considering a button on hes back where you can select “Good” or “Evil”, wouldn’t that be cute?

We presently have one big problem. The motors is to heavy geared. The motors are strong enough indeed, but it is impossible to run the thing slowly or to run something near a straight line. The motors are hacked battery drills, so the only way increase the torque is putting on smaller wheels, which is kind of tricky. Also we will then loose the incredible top speed is has now. Just see him spinning around in the video below 🙂

A challenging but plausible solution could be to computer control the motor speed. The motors are already controlled by a Arduino card so the main problem here is to get a fast motor speed feedback so the computer can calculate the thrust to compensate for any over/underspeed. But HOW?

Dear people. How can I create a fast and reliable speed sensor/counter for a hacked drill motor, which I can feed back to the Arduino?
