People working in the Leg Laboratory were legged locomotion enthusiasts of all stripes.
They represented several disciplines, including electrical engineering, mechanical
engineering, computer science, physics, biomechanics, and aero/astro.

of Electrical Engineering and Computer Science and a member of the Artificial Intelligence
Lab. He is now president of the company he co-founded, Boston
Dynamics, Inc.

- Chris Morse designed and built Coco for his Master's Thesis in Mechanical Engineering.
- Chris Wren did his Senior Thesis in
the Leg Lab using physics-based simulation to model a tree blowing in the wind. After
graduating and spending a year at BDI, Chris jointed the Media Lab as a graduate student.
- Chee-Meng Chew worked on learning applied to bipedal walking algorithms for his Mechanical Engineering PhD Degree. He is a now a professor at the University of Singapore.
- Clay Thompson worked on passive dynamic running.
- Daniell Hebert worked on the Zero Gravity machine.
- Daniel Paluska
worked on design and control of a physical version of a luxo lamp,
many series elastic actuator designs, some new feet for spring
flamingo, and the design and control of the 3D biped, M2. As of 2003, he is working with
Hugh Herr at the Media Lab in the Biomechatronics group.
- Dave Barrett was a mechanical designer in the Leg Lab for three years. He is currently
working on swimming robots in the MIT Department of Ocean Engineering.
- David Bailey worked on
Geekbot looking at smooth transfer of support for his M.S. Thesis. He is currently working
at Sarcos Research Corporation.
- David Robinson
developed Series Elastic Actuators for use in M2 and M4.
- Eugene Hastings
- Francis C. Wimberly
- Garth Zeglin
built the uniroo and first made it hop. He is currently a graduate student in Matt Mason's
lab at CMU.
- Gregory Huang was a postdoctoral associate working on models of
biped and quadruped locomotion, with applications to orthotics.
- Jeff Koechling did his PhD thesis studying the limits of robot running speed. As part of
that work he programmed the planar biped to run fast: It set the world land speed record
for legged robots by running over 13 mph. Jeff is currently Chief Scientist at Boston Dynamics, Inc.
- Jeffrey Miller
- Jerry Pratt was a graduate student at the
LegLab from 1994 to 2000. There he developed novel control
techniques and algorithms for bipedal walking. He and Peter Dilworth designed and built
Spring Turkey in 1994-95. Jerry designed, built, and controlled Spring
Flamingo between 1996 and 2000. In 2000 Jerry Co-founded Yobotics, Inc. and in 2002 he joined the Institute for Human and
Machine Cognition in Pensacola, Florida.
- Jessica
Hodgins did her PhD thesis in the Leg Lab, working on foot placement for the planar
biped. In the course of doing her thesis, she programmed the planar biped to run up and
down a set of three steps. She also helped make the planar biped do front somersaults.
After her PhD thesis she did a one-year postdoc in the lab working on animated characters.
She is currently a professor in the College of Computing and a member of the Graphics
Visualization and Usability Center at Georgia Institute of Technology, Atlanta, GA, where
she runs their Animation Lab.
- Jianjuen "John" Hu
- Jiping He
- Joanna Bryson
- Jonathan Hurst was a
student from CMU who worked on Series Elastic Actuators at the Leg Lab one summer.
- Karl Leeser completed a
Master Thesis in the Leg Lab in 1996. He studyied the role of an articulated spine in
quadruped running, including construction and experiments with the Planar Quadruped.
- Karl Murphy did a Master's Thesis in the Lab when it was at CMU on coupled oscillation
in bounding.
- Kenneth Y. Goldberg
- Lance Borvansky did a Master's Thesis simulating ostrich running.
