    Abstract: A method of monitoring movement of a robotic arm, the robotic arm being arranged to be moved by an actuator, the method comprising: determining an expected robotic arm condition based on a known robotic condition and a torque applied to the robotic arm by the actuator; measuring an actual robotic arm condition during movement of the arm caused by the applied torque; and determining whether a collision has occurred by comparing the actual robotic arm condition with the expected robotic arm condition and generating a collision signal if a difference between the actual robotic arm condition and the expected robotic arm condition exceeds a threshold.

    Abstract: The present disclosure provides position detector for an electric machine. The detector uses one or more proximity sensors, such as eddy current sensors, to detect features on the rotor of an electric machine. The detectable feature may be a spiral groove, which has a unique position at any given point around the circumference of the rotor. As the rotor is typically steel, the proximity sensors produce different output values depending on the degree to which they are aligned with the groove. As such, given that the groove has a unique position at any given location, the output of the proximity sensors is also unique for any given position. This enables the position of the rotor with respect to the sensors to be determined.

    Abstract: The present disclosure provides a rotor body which utilises a combination of bridges and openings in order to improve the structural strength of the rotor while reducing magnetic flux leakage. The rotor can be used in electric machines with any number of poles comprising thin rotor laminations. Embodiments shown here by example are generally high pole count, but the principles disclosed can be applied to any number of poles and any size of motor. As such, each layer is provided with a back iron, bridging all of the slots, in order to provide the required degree of structural integrity. At the inner or outer diameter of the rotor body, for a given slot, most of the layers include an opening, while the remaining layers include a bridge.
