According to a press release by UM on its official website on Monday, August 15, 2011, human-like robot Mabel can run as fast as 6.8 mph, with an average speed of 4.4 mph.

Mabel was said to have built in 2008 in collaboration with Jonathan Hurst, who was then a doctoral student at the Robotics Institute at Carnegie Mellon University. It was funded by the National Science Foundation and the Defense Advanced Research Projects Agency.

“It’s stunning; I have never seen a machine doing a motion like this.” UM Department of Electrical Engineering and Computer Science professor Jessy Grizzle was quoted on the report.

“Few robots can run, and the researchers say no machine but Mabel can do it with such a human-like gait. Its weight is distributed like a person’s.” Grizzle added.

“It has a heavier torso and light, flexible legs with springs that act like tendons. Mabel is in the air for 40 percent of each stride, “like a real runner,” Grizzle explained further.

Grizzle, along with UM doctoral students Koushil Sreenath and Hae-Won Park have reportedly spent the years since ratcheting up Mabel’s training, which started off walking smoothly and quickly over flat surfaces.

The running feedback algorithm was designed by Koushil Sreenath as part of his PhD dissertation, while the details of the model robot was developed by Hae-won Park as part of his PhD dissertation.

“Wheels are a great way to move across flat surfaces, but when the ground gets rocky, two legs are much more efficient.” Sreenath said on the report.
