Bill is the HCMI Lab's ATRV-Jr robot. In his “spare time,” Spencer Clark has been tinkering with getting Bill running again.
Joystick drive is very temperamental. Sometimes it works, sometimes it doesn't. Spencer Clark's suspicion is that there is a short in the ancient joystick we're using. Assuming that the joystick is working, you can drive bill around by choosing “Joystick drive” from the onboard menu system. Next, you have to tap the right-most button on the joystick twice, then hold the left-most button. If the joystick is working, you will see messages appear on the screen as you do this. Continue to hold the left button and use the joystick to drive. Be sure that the brake is disabled first. Try not to crash into too many things.
