My name is Andy Schwartz and I am building a R2D2 robot. Now at first
thought you might ask why am I posting here. But we are doing a lot of very
similar things and I hope to piggyback off your experience. My R2D2 uses
130 watt scooter motors one in each leg. I am using a speed controller to
run the motors as well as one to turn the dome. So this is similar to your
treads and turning the top. I am using RC transmitter and receiver inside
the droid.
Can you give me your thoughts on what is the best speed controller and RC
transmitter to use for a 100 or a 200 lb system?
I dont recall R2D2 ever moving in reverse. If I am correct, then you may only need to power his front wheels. Just use a castor for his rear support. You can then get away with a scooter motor controller (they pop up on Ebay and are usually real cheap). You can then power your fron 2 wheels using the Tri-Pact switch set up and put the 1 controller between the switches and the battery. You will need to rig a servo to rotate the speed control but thats part of the fun designing & building vs. buying right? Here is the link to the speed control page at rctankcombat.com that includes a description of the TriPact setup

This seems like the simplest system to try and wont cost a lot. Plus, with the recent interest in RPVs, mebe you will have a chance to submit R2D2 for official designation :-)
