This circuit is used to create a simple "edgebot" sumo robot. Being an edgebot refers that it will repeat the same backup/turn/go forward action when it's single edge sensor detects the edge of the ring. This version of the circuit is quite simple, and always turns the same way.
Escaps back in stock!

Well, the last batch of Escap gearmotors went very fast. Let's hope this batch lasts a bit longer!
Unlike the last set, this set has a higher reduction ratio of 663:1 instead of 362:1. This means it starts turning 0.46V (!) drawing only 3.3mA (!!)
It's a 3V rated motor, but our tests show that they spin quite nicely at 5V, drawing 4.2mA free (!!!) at 22rpm. Don't know what the stall current draw is, as we're scared to strip these delicate gears, but it's greater than 150mA. Check them out!
