Biomechanical performance of wearable robotic systems

Steve Collins, Mechanical Engineering

The CMU Efficient Biomechatronics Laboratory is developing novel experimental techniques for developing controllers for human biomechanical assistance and rehabilitation. We have developed versatile laboratory testbeds capable of synthesizing a wide range of sensory information and performing high-bandwidth joint torque control. A robotic foot-ankle prosthesis and a robotic foot-ankle orthosis have been developed and are ready for use in experiments. The goal of this project is to perform controlled biomechanics experiments to evaluate proposed assistance functionalities. We will collect data on body kinematics, kinetics, and metabolics, and analyze these to understand the effects of various control techniques.

This project will entail:

 - Learning how to program and operate experimental biomechatronic devices

 - Learning how to collect biomechanics data

 - Learning how to analyze biomechanics data

 - Conduct human-subject experiments

 - Analyze results and draw broader conclusions for human rehabilitation

Skills needed:

 - Desire to learn experimental biomechanics techniques

 - Matlab proficiency

 - Ability to comfortably interact with subjects and graduate student supervisors

 - Reliability and professionalism

Students must be eligible for the honors research program, which includes 18-24 credits over two semesters. Please send your resume to Steve Collins, stevecollins@cmu.edu.
