Getting a Humanoid to walk more “Human”

Asimo, take some notes;)

Using 1930s theories from a physiologist by the name of Nikolai Bernstien, roboticists are able to build the world’s fastest dynamically walking robot!

Runbot is a small, biped robot which can move at speeds of more than three leg lengths per second, slightly slower than the fastest walking human.

Bernstein said that animal movement was not under the total control of the brain but rather, “local circuits” did most of the command and control work.

The brain was involved in the process of walking, he said, only when the understood parameters were altered, such as moving from one type of terrain to another, or dealing with uneven surfaces.

How does Runbot walk you ask?

Runbot Gait

  • Frames 1 – 3: The robot’s momentum causes the robot to rise on its standing leg and a motor moves the swinging leg into position
  • Frame 3: The stretch sensor of the swinging leg is activated, which triggers the knee joint to straighten
  • Frames 3-6: The robot falls forward naturally, with no motor functions being used, and catches itself on the next standing leg
  • Frame 6: As the swinging leg touches the ground, the ground contact sensor in the foot triggers the hip extensor and the knee joint of the standing leg and the hip and knee joints of the swinging leg to swap roles
