My name is Blake Nolingberg and I'm a student at the University of Houston's College of Technology. My senior project group is trying to make a robotic fertilizer spreader. And we are hoping some of you might be able to help us with a question we have.
We are building our project from a donated golf cart. The current problem we are facing is finding a cheap motor control circuit for a
36v golf cart motor. Our logic is very simple. We do not need lots of motor control. The robot will only be made to operate in square or rectangular spaces at a relatively constant speed. We need it to travel in a straight line, turn (each turn will be identical), and stop. We do not plan to vary the speed and other functions that expensive motor control circuits offer. We plan on making the unit turn w/ a different servo motor as well. The only thing our motor control circuit needs to do is make the motor start and stop when the microprocessor instructs it to.Do you have any ideas about where to find or how to build such a motor control circuit? Are there any other ways to control a DC motor besides PWM?
Thanks a lot, Blake
