Abstract: A magnetic biasing assembly comprising: an inner element comprising: a north polarised inner arc, and a south polarised inner arc disposed axially adjacent to the north polarised inner arc, and an outer element arranged to rotate relative to the inner element about an axis, the inner and outer elements being substantially concentric, the outer element comprising: a north polarised outer arc, and a south polarised outer arc disposed axially adjacent to the north polarised outer arc, wherein the inner and outer polarised arcs are arranged so as to have a stable equilibrium position and are arranged to exert a magnetic moment between the inner and outer elements in a direction towards the stable equilibrium position when the inner and outer elements are not in the stable equilibrium position.

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.
