You connect the motor to a differential gear. One end of the differential gear
turns the wheel; the other end turns something to press the sensor.
Or you suspend the chassis with shock absorbers, then put sensors to detect
the direction to which the chassis is pushed.
Or you place two sensors around a free wheel. One sensor detects whether the
free wheel points to the front or the back, the other left or right.
