Desert RHex, a modified Research RHex robot

Desert RHex


In June 2009, Kodlab members took a Research RHex robot to the Mojave Desert, for the purpose of evaluating the performance of legged robots in adverse, mountainous, desert terrain.

The robot received a significant overhaul in preparation for the trip, outfitting it with sensors and electronics to collect important locomotion data, as well as designing and installing a robust shell to endure the difficult environment. A white shell made from both polycarbonate and carbon fiber greatly helped in protecting the RHex robot from the harsh desert environment during tests.

In March 2010, the robot returned to the desert, this time with automated tuning algorithms that allowed it to learn efficient gaits for sandy and rocky terrain. A video of the robot in action follows:
