Hi, I'm David in Arkansas. I've been following the EZ-Robot project with great interest. Real Wall-e is the coolest thing ever btw! I hope to build a telepresence bot with EZ-B someday, but my ultimate goal will be to have EZ-B help me drive my wheelchair. I have Duchenne Muscular Dystrophy (DMD) and even the most sensitive joystick has become a chore to drive just around the house. Software has always been the stumbling block for me & robotics projects, thx DJ for solving that problem for us all!

Anyway, I imagine driving with my trackball, having distance sensors all around to avoid hitting stuff, trans-versing my house by following a line on the floor, and getting around public places by following an orange circle or glyph on someones back. EZ-B controlling the chair will involve servos on the 2nd joystick/controls, though I do know what potentiometers my joystick uses if digital potentiometer support ever came about.
