Simulation-based Design of Devices to Augment Human Movement

The upcoming meeting of the IEEE Consultants’ Network of Northern New Jersey (, scheduled for Thursday, June 12, 6:30 PM, features a presentation by John Rogers.

About the Topic

Musculoskeletal dynamic simulation can be used to aid the design of devices that augment human movement. Devices in this category are like exoskeletons for single joints?they augment the load-carrying ability of the human by taking a share of the torque at the body joint.

The design of devices requires knowledge of the expected speed, torque, and power profiles at the joint over time for a particular motion (like running). In-vivo measurement of these quantities is inherently difficult, but they can be predicted by simulation. This study demonstrates how to use the joint torques and power from simulation to help select motors and springs for an augmentation device. The brief will show how to estimate motor speed, torque, current, and power for a hypothetical hip actuator for augmented running.

About the Speaker(s)

John Rogers is an Associate Professor in the Department of Civil and Mechanical Engineering at West Point, the United States Military Academy. He teaches mechatronic design, computer graphics, programming, dynamics, and engineering materials. His research interests are the design of unmanned systems, modeling of dynamic systems, and the biomechanics of machine-assisted human movement. Dr. Rogers earned the Ph.D. degree in mechanical engineering at Rensselaer Polytechnic Institute in 2003. Prior to joining West Point, he built and tested underwater systems, analyzed structures, and designed industrial electro-hydraulic systems. He is a registered professional engineer.
