ATRIAS 2.1 Handbook
ATRIAS 2.1 is the third physical realization of the ATRIAS concept of an actuated spring mass walking, running and jumping bipedal robot. ATRIAS 2.1 is designed for un-tethered, 3D walking and running over unpredictable, rough terrain while maintaining a reasonably high energy economy. Future work with this robot will be to develop and demonstrate these goals and further scientific knowledge in the field of legged locomotion.
