Advanced Leg Brace Attachment for Servomotor Systems

This innovative system features a leg brace attachment for servomotor drive, precisely actuating hip and knee joints while holding the ankle joint in a static position. The hip joint is powered by a rotation motor, the knee joint by a motor with ball-screw mechanism and linkage. Torque response is measured at the hip and ankle with reaction torque transducers, and knee joint torque is calculated from force measured by a reaction force transducer. Developed by Ming Wu, PhD, and team.

Presentation Transcript

  1. Servomotor systems with leg brace attachment. Servomotor drive system actuates leg from hip and knee joints, and ankle joint is held statically by leg brace. Hip joint is driven directly by rotation motor, while knee joint is driven by motor through ball-screw mechanism and linkage. Reaction torque transducers at hip and ankle measure joint torque response to imposed movement. Reaction force transducer is attached at bottom of ball-screw mechanism to measure force from which knee joint torque is calculated. Ming Wu, PhD; et.al
