One problem/inconvenience we had is that the wheels would have to be pointed forwards when you turned on the robot otherwise the wrong direction was forward for the joysticks (we were using an encoder).

Austria Microsystems AS5030 absolute magnetic encoder.

US Digital MA3 MA3 absolute magnetic encoder

Cherry AN8

Vishay 981 HE
