Separate issues, the adder/subtractor (is there really not a better existing
name for this device btw?) is to deal with the slight variations in motor

problem with this configuration, because the resistance of the front wheels
to slipping sideways makes the curve entirely unnoticable over less than 2-3
meters.

through the improvised rotation sensor, so when the bot is turning I get
narrow pulses as that wheel tracks around the circle.
