Abstract
A multi-axis force platform for determining forces and moments exerted on the platform along x, y and z axes includes at least one multi-axis spring. The multi-axis spring includes a block of rigid material through which a pattern of slots pass through to form a series of deflectable beams separated from each other by the slots. The deflectable beams surround an interior region of the spring and elastically couple the interior region of the spring to an outer region of the spring such that the interior region can deflect relative to the outer region along x, y and z axes when subjected to a load. One or more magnetic sensors are positioned within the interior region of the spring for sensing loads exerted on the spring.
