Cassie, a bipedal robot designed by researchers at Oregon State University, set a bipedal robot record by running 24.73 seconds for 100m (about 14.5km/h). The record is based on the robot’s previous exploits. In particular, the machine covered 5 kilometers in 2021 in just over 53 minutes, on a single battery charge.
The biggest challenge for the researchers was getting the robot to accomplish the feat while standing and complete it in the same spot without falling over. Equipped without sensors or cameras, the robot operated blindly. Developed in 2017, the robot works using machine learning.
Devin Crowley, a student who led the preparation, notes that “machine learning approaches have been used for pattern recognition for a long time, such as image recognition, but applying it to robot movements is new.”
Promising record for robotics
Jonathan Hurst, chief technology officer for Agility Robotics and a professor of robotics at Oregon State, predicts that the Cassie robot is “perhaps the first bipedal robot to learn to run, but it won’t be the last. I think experiments like this are taking place.” finished”. play an important role in the future of robotics. The exciting thing about this race is its potential. I think progress will accelerate.”
The researchers condensed a year’s worth of simulation and training into a week to prepare the robot. The process is called “parallelization”, during which multiple calculations and simulations are performed simultaneously.
