hello,
I have been working on a project off and on for several months and thought I would share my progress.
The idea is basically a battlebot with everyday usefulness. A metal frame with 2 wheelchair motors powered by a car battery, with a lawnmower attached to it. I know this has been done before, but I just wanted to try it myself.
here is a web page that I made to track the project:
http://rediculouslygoodlooking.com/site/lawnmower.html
I have specifically been focusing on the H-bridge motor driver, building it from P/N channel mosfets and the code to translate a PPM servo signal from a typical R/C reciever into a PWM value that can drive the H-bridge.
I will post some eagle files of the H-bridge if anyone is interested.
Also, I am interested in coming up with a good PCB design for a high powered H-bridge (around 25amp or higher at 12v), so if anyone has any suggestions to the circuits I have already come up with, please feel free to suggest changes.
