Power Wheels Robotic Tank M1
The Robotic Tank you see here was capable of speeds approaching 10MPH With myself on it. Powered by 2 250W electric Scooter motors, it was a very large project. The tracks were steel conveyor track, drilled and bolts inserted. 3 Pneumatic tires provided suspension and the frame was constructed out of Aluminum T6061T6 and Steel frame. I could never get the mechanics to work long enough for more than 5 minutes of ride time before it threw the chain or a sprocket slipped. I will revisit this project in the near future, but for now it sits in pieces, in a few boxes. No video exists of it in operation.
The Motor driver was a 24V DPDT relay, one for each motor. It also had a opto isolator that allowed for control of the relays coil, so It could be controlled by a 5V signal. There were going to be electronics mounted to it to allow fully autonomous operation, but It was never in a state where it was able to work, unfortunately.
