Using this system, the Cheetah can easily clear objects more than 30 centimeters tall, and they don’t even have to be perfectly aligned with its path. Several of the tests in the video show the barriers being placed slightly at an angle. It only takes about 100 milliseconds for the adjustment process to happen, so the robot can respond to unexpected changes in the terrain.
The untethered test at the end of the video is the most impressive part. The robot maintains an average speed of five miles per hour throughout the test, which is about the same as a light jog for humans. On the track with more time to calculate the position of barriers, Cheetah has a 90% success rate on its jumps. With the treadmill, it’s a little less successful (70%) due to the shorter lead time. The team expects these numbers to improve over time.
