Im a second year mechanical engineer at university, we have a group project to design a robot for robot wars. To do this we have to design something called a half H bridge. I have very little understanding of electrical engineering and our electrical engineer has dropped out of uni leaving us to do this alone. Any help designing the circuit would be greatly appreciated. The robot will have two motors (12V) that are used to steer (slow down on one wheel to steer type idea) The motor controller must be able to go fast, slow, and stop on both motors independently. If you need anymore information to work with please let me know thanks.
