You’ve got to walk before you can run, right? perhaps not, if this bipedal dino-like running robot is any type of indication.

Officially dubbed a “Planar Elliptical Runner,” the bot is a test platform for bipedal locomotion from the Institute for Human as well as machine Cognition. Taking motivation from the gait of an ostrich — we believe it looks more like a T. rex or velociraptor, however exact same difference — [Jerry Pratt]’s team at IHMC have developed something quite remarkable. contrary to all the bipedal as well as quadrupedal robots we’ve seen, like Boston Dynamics’ huge Dog and PETMAN, which all relatively bristle with sensors as well as actuators, the PER is extremely stripped down.

A single motor runs the entire drive chain utilizing linkages that will look familiar to anyone who has taken an elliptical fitness instructor apart, as well as there’s not a computer or sensor on board. The PER keeps its balance by what the team phone calls “reactive resilience”: torsion springs between the drive sprocket as well as cranks immediately modulate the power to both the landing leg as well as the swing leg to confer stability during a run. The video below shows this well if you single-frame it starting at 2:03; note the variable angles of the crank arms as the robot works with its stride.

The treadmill tests are constrained by a couple of plastic sheets, however the next version will run free. It’s not remove yet exactly how directional manage will be achieved, not is it obvious exactly how the PER will be able to stop running as well as keep its balance. however it’s an fascinating advance in locomotion as well as we look ahead to seeing what IHMC’s next technique will be.
