General beginner's PS2 Wireless Controller question

Hello,

I would like to find out how to control a relatively small robot with a PS2 wireless controller. I currently have a sabertooth 2x5 motor controller with two 7.2V DC motors along with two HS-422 servos. I already purchased a 6-channel Hitec controller/receiver, but it turns out that I cannot use it due to size constraints.

My simple setup currently consists of a 7.2V NiMH battery connected to the Sabertooth, the two DC motors connected to the sabertooth, the sabertooth connected to the Hitec receiver, and the servos also connected to the receiver. I have tested this setup with the Hitec contoller and it works fine.

How would I replace the Hitec controller with the much smaller PS2 controller? From what I have read so far, I would likely need to buy a Bot Board II and a BASIC Atom microcontroller, but I am at a loss as to where I should go from there.

I have some experience programming microcontrollers, but only with PIC controllers, and only relatively simple programming. I am not terrified with the prospect of having to program, but if the code already exists, I would prefer to just use that.

If anyone could tell me what I need to purchase and how to make it work with my current setup, I would be very thankful.

This is easier than you might thing.

Thank you very much for the information. A quick question though: Is it possible to power the bot board through the sabertooth? It is not a big problem if it cannot be done, I just wanted to make sure my understanding is correct. Thanks again.

Not sure of your exact meaning. The Sabertooth has a 5vdc output that is good for maybe a couple hundred milliamps. In theory it could power the Bot Board II. But if you’re going to be attaching servos at some point down the road it will never work. It’s best to power the Bot Board and the Sabertooth from the battery directly.
