Re: Robot loosing communication when switching directions

This is exactly the result when the Crio chassis is electrically connected to the frame and a motor or other wiring also is connected with the frame. Typical of certain Banebots motors shipped after the beginning of build in 2011, was a case short. Even if you were sure you had adequate insulation under the Crio, check it again with a meter. When you reverse motors under this condition, the power going to the Crio is cut in half by the short. The result is a Crio reboot.
