Oregon State University's Dynamic Robotics Laboratory has developed a robot which is believed to be the fastest bipedal robot ever designed. The robot dubbed 'Atrias', which stands for Assume the Robot is a Sphere, has unusual leg design which its makers think is central to its agility and efficiency. The robot is currently under training to master different speeds before it is launched.

They explained that the four-bar carbon-fiber leg mechanism is very lightweight, softening each football instead of sending large jerks to the body.

The robot's legs are mounted to series-elastic fiberglass springs, which act as suspension and a means of mechanical energy storage.

As everyone has some or the other flaws the robot also has one. The one downfall of the Atrias is that it cannot stand still. It does not have feet for standing still at one place.

Oregon State University said, "The mathematics commonly used to control robotic walking just doesn't work for Atrias. Researchers at Dynamic Robotics Laboratory, in collaboration with Dr. Hartmut Geyer's laboratory at Carnegie Mellon University, have been constantly inventing their own controllers to make Atrias go".

The laboratory explains that robots don't typically have such spindly legs, tiny feet, or big springs attached to their motors.

The springs attached to it absorb and recycle energy that would be lost whenever it would have covered very step.

The lightweight shins and thighs reduce shock loads when its legs swing and hit the ground, they explained.

Like a high-end sports car, all of Atrias' mechanisms are designed and tuned to cooperate with each other and enable maximum performance.
