ATRIAS takes its first steps!!
This video is recorded 3 days after the completion of ATRIAS 2.1. This robot is the first of three identical ATRIAS 2.1 biped robots designed and built at Oregon State University's Dynamic Robotics Lab. One robot will stay at Oregon State while the other two will be delivered to collaborating research labs at the University of Michigan and the Robotics Institute of Carnegie Mellon University.
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. While designed as a 3D capable robot, at this stage in its development we are using a support boom to restrict it to 2D motion. You can think of it as our training wheels.
ATRIAS uses electric motors to actuate its joints. In the first clip labeled "Off-Board Power" we use large capacity, deep cycle truck batteries, and run wires to the robot through the support boom. In the second clip labeled "On-Board Power" ATRIAS is running on internal LiPo batteries. The robot is physically disconnected from any external electrical equipment Another avenue of future work with this robot is to determine its energy economy, or, how far can it go on a single battery charge.
