Radio Control BoeBot

Posts: 5
I have been creating different things with my BoeBot Kit for a while now and looking to try something more advanced.
I want to create a robot that can go from autonomous to RC controlled and I am looking for someone who has done this and has already outlined the project before I buy any expensive parts.
I already have a robot chassis with 2 motors. I want to buy a motor controller and use my RC radio to control the whole thing.
I have played with my RC radio set and am able to pick up signals from the receiver and do certain things, but many motor controllers like Pololu Trex have RC hook-ups to all the RC channels (if needed) and channel 5 toggles between autonomous (serial) and RC.
This sounds just like what I want to do. Has anyone used this, and extra things I need to know about before buying my parts?
Can someone vouch for the Pololu trex? what rc radio set did you use?
Thanks,
Justin

Take a look at the attached UAV BS2p code as an example.

If you are going to send·a Robot·to save the world, you·better make sure it likes it the way it is!
··· I have done something simillar using an old RC transmitter and reciever, a BS2, and a pololou dual·micro motor controller.· I used the BS2 to read the outputs of the reciever with the PULSIN in command, and then scaled the time from 0 to 127, so that I could send that value to the motor controller for the speed of each motor (right and left wheel).· If the BS2 did not see any activity on the throttle line the bot would switch to autonomous mode, and use a Ping )))·sensor to roam the room.· As soon as the BS2 reconized me pulling the throttle trigger it would switch back to manual mode.
··· The·drivetrain I used was a set of Tamiya gear boxes with three volt motors.· It was pretty cool, but now I am switching it over to a PS2 controller and using the RF transmitter package from Parallax.· If you have 2 BS2s you can use one to read the PS2 controller and send data with the transmitter, and· have·the other·BS2 with the reciever on the bot.· This is a little more expensive setup, but you will have more options.· I will get some pics posted as soon as I can.
Hope I was of some help, JJ.
PS2 controll with RF is a work in progress, but I should have a rough draft done tonight.

I like the wheels.
Resourceful.
