MIT’s Robotic Mini Cheetah can jump across uneven terrain in real-time
A novel control technique, demonstrated by’s robotic mini cheetah, allows four-legged robots to hop across rough terrain in real time.
A loping cheetah bounds across a rolling meadow, leaping over abrupt gaps in the rocky terrain. The movement appears to be effortless, but getting a robot to move in this manner is a very different situation.
Four-legged robots inspired by the movement of cheetahs and other animals have made significant advances in recent years, but they still lag behind their mammalian counterparts when traversing through a landscape with quick elevation changes.
“In those settings, you need to use vision in order to avoid failure. For example, stepping in a gap is difficult to avoid if you can’t see it. Although there are some existing methods for incorporating vision into legged locomotion, most of them aren’t really suitable for use with emerging agile robotic systems,” says Gabriel Margolis, a PhD student in Pulkit Agrawal’s lab at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL).
Margolis and his colleagues have now devised a technique that improves the speed and agility of legged robots as they jump across terrain gaps. The unique control system is divided into two parts: one that analyses real-time input from a video camera attached on the robot’s front, and another that interprets that information into instructions for how the robot should move its body....
