Research interests

My interest is in controlled, highly dynamic systems; robots that move swiftly and require careful mechanical design due to limitations on the inertia of the system and the speed of computer control.

My primary project and goal is to build a bipedal robot. This robot will be untethered, and capable of walking as well as running and jumping. I am specifically interested in creating a mechanism that has the correct physical properties for energy-efficiency and passive dynamics while walking and running.

This section last updated - May 2006.

Research interest keywords

actuators, control, legged locomotion, and mechanisms

Current Labs & Groups

Microdynamic Systems Laboratory - Exploring the limits of robotics in terms of speed, precision, dexterity and miniaturization.

Current Projects [Past projects]

Actuator with Mechanically Adjustable Series Compliance - We are developing actuation methods for highly dynamic legged locomotion.

The Electric Cable Differential (ECD) Leg - We are designing a bipedal robot to be capable of running, walking, jumping, hopping, and generally behaving in a highly dynamic manner.
