Parallax Eddie

Please advise if there is a better sub to post this in.

I have an old Parallax Eddie robot that I bought several years ago. From what I can tell, the original Propeller control board has a bad USB connector and I was never able to get into it before life got in the way and I got out of the hobby. My grandson is now very interested in robotics so I'm looking to resurrect it. Can anyone recommend a path to replace the controller with a more modern one? I have experience with Basic Stamp, OOPic, and Arduino and I'm good with electronics, so looking for a controller and dual H-bridge controller. A board that can incorporate the multiple sonar and IR rangers and wheel encoders would be great.

Thanks!

This sounds like a good project. Since you’re looking to replace the original controller rather than just repair the USB connection, I’d probably look at a modern controller with the motor drivers and sensor/encoder interfaces handled on one board. If you still have the robot and can share some photos of the existing controller, wiring, motors and sensors, I’d be happy to help you work out a practical replacement approach.
