Overview
Legged robots, unlike wheeled robots, have the potential to access
nearly all of the earth's land mass, enabling robotic applications in
areas where they are currently infeasible. However, the current control
software for legged robots is quite limited, and does not let them
realize this potential.
In the Learning Locomotion project, we seek to develop software that
significantly advances the state of the art in robotic quadruped
locomotion over rough terrain. To achieve this goal, we develop and
apply novel control and machine learning algorithms.
We gratefully acknowledge DARPA for supporting this work.
