OK, I have some standard sharp sensors on the robot both Horz and Vert. I have no servos on them. When I do a scan with the radar, it scans, but it doesn't show the red dots. But, when I hook a Meter or Graph, it sees when I put something in front. But, no red dots. That is weird. The Ping units show the red dots also.
Sorry if I did not word this correctly.
