RC independent of the OI

[ajsetter]

Hi, I'm one of the programmers on team 612. We're currently working on a baby-walker type project for a young boy who was born disabled. The project was started last year and there is a possibility for a new one this year. One of our current limitations that I have tried to eliminate is in order for the RC to function properly (or at all for that matter), the OI needs to be plugged in. We've rigged up a nice joystick-OI-radio package, but it is still required to be plugged in (or powered by some 9-volts) by the parents whenever their son wants to use his walker. We've been trying to find a way to have the RC independent of the OI (i,e, not have the RC wait for a signal from the OI's radio), but still be able to have the joystick control it when needed. So far we've come up empty handed, is there any suggestions that anyone can give us? Maybe we should contact Innovation First directly? Any help would be great! Thanks
