Ultrasonic Only Working "On-Line"
We took the sample ultrasonic code and downloaded it onto our robot. I found that when we start the program in the debugger, the ultrasonic works great. When we then unplug the robot and turn the power off and on, we get nothing.
One or two quick twitches and the robot will not move again. We have tried starting the robot at any number of different wall distances...same thing.
