  • Publication number: 20230123289
    Abstract: An embodiment includes an exoskeleton robotic system including: a first linkage; a bearing coupled to the first linkage; a joint including a motor configured to move the first linkage along the bearing; an axial load sensor configured to sense an axial force transmitted to the axial load sensor via the joint, the axial force including one of tension or compression but not torque; a bracket including first and second bracket locations and first and second arms; and a housing that includes at least part of the joint and which couples the bracket to the bearing. The bracket couples to the housing at the first bracket location and couples to the axial load sensor at the second bracket location. The first arm couples the second arm to the first bracket location, and the second arm couples the first arm to the second bracket location.
