A measurement board (20) for determining rotor positions of motor units (10) of a robot unit (1). The measurement board (20) comprises a processing unit (22) comprising a data storage (23) adapted to store rotor positions, and a logic unit (24) adapted to determine rotor positions on basis of the stored rotor positions in the data storage (23) and information from position sensors (12) at the motor units (10). The measurement board (20) further comprises an energy harvesting device (30) for generating energy from an ambient energy source. The energy harvesting device (30) is adapted to provide energy to the processing unit (22). |
