- Topic: Maqueen dead motorsYou Reply: Found the issue: one of the batteries failed, so there was enough voltage to drive the leds but not the motors. Fresh new batteries inserted and the robot is alive!

encoder run stable now, but only 12 counts per revolution due to the wheel setup that has only 12 white teeth.
In my eyes, the encoder/wheel kit cannot deliver more than 12 counts per revolution by design. With this setup, I do not understand the way Sig-A and Sig-B shall work as they are quite far apart and are not looking at the same white tooth. The example code does not give a hint.
(I use the ROB0049 plus Romeo v2)

I dis-assembled the robot again, the version of the encoder is v1.1 dated 12/27/2011 as on the product page so I asusme I have the actual one.
When reassembling I noticed that the original assembly (the robot came per-assembled) did not position the motor and the encoder in the deepest position. When putting the motor and encoder in the deepest position, the two encoder deliver the same counts. I think, the outer position picked up the rim of the wheel and therefore in-stable triggers.
