A bipedal robot can now put its best foot forward, stepping with a heel-toe motion that copies human locomotion more closely than flat-footed robot walkers can.
By rocking its "feet" forward from the heel and pushing off at the toe, the DURUS robot closely imitates the walking motion of people, making it more energy-efficient and better at navigating uneven terrain, according to Christian Hubicki, a postdoctoral fellow in robotics at the Georgia Institute of Technology and one of the researchers who helped DURUS find its footing.
The humanoid robot DURUS was designed collaboratively by the research nonprofit SRI International and Georgia Tech's Advanced Mechanical Bipedal Experimental Robotics (AMBER) Lab. An earlier DURUS design was modified to accommodate the new manner of walking, enabled by a novel mathematical algorithm that adjusts the robot's momentum and balance, one step at a time.
