Mini Sumo Edge Detection

LawrencL

My MiniSumo doesn't seem to detect the white·edge of the sumo ring consistently, especially when it is approaching the edge head on.· It can run off the board by itself or be pushed off by an opponent too easily.

When I twist the sensors on their mounting bolt to be closer to the scoop, it works better.· It seems it needs to detect the
edge·sooner.

What I would like to do is mount the edge detection sensors lower to the sumo board and move them forward against the scoop.

This would place them farther from the wheels and give a little more time to back off from the edge before falling off.

Has anyone tried this?

Does anyone have any other ideas?

Does anyone have a mini-sumo program they feel is a improvement over the one that Parallax provides?

Thanks,

Lawrence

Lighting conditions can affect the performance of those sensors; consider using a bit of black paper to block ligh that may be entering from the side. Also, you can change the threshold in the program to make edge detection more or less sensitive.
