Mechanical Testing of Musculoskeletal Joints
The BioRobotics Core at the Cleveland Clinic has several robotic systems considered musculoskeletal simulators. Mechanical testing of knee joints will be performed using a simVitro System. This system includes:
- A 6 DOF robot (Rotopod R2000) with a rotary stage mounted to the top to yeild a 7th DOF for increased range of motion.
- An Optotrak motion tracking system to digitize the robotic system hardware, specimen anatomy, and to create and control motions and loads in a Grood and Suntay knee joint coordinate system specific to the specimen.
- A universal force sensor (UFS) to measure the tibia loads.
This system allows the robot to operate in real-time force feedback control, as well as position control, so that loading trajectories can be applied to determine joint kinetic and kinematic responses.
