Carnegie Mellon University’s Biorobotics Lab shows off their new modular snake robot, Unified Snake. Watch as it climbs up a pole, performs rolls, and sidewinds.

This work considers two issues: snake robot locomotion and modular robot design. We achieve snake robot locomotion by designing gaits, which are cyclic internal motions that allow the mechanism to interact with the environment to propel itself forward. Our gaits enable snake robots to maneuver through a variety three-dimensional terrains and include swimming and climbing. The robots, themselves, are a modular chain of single degree of freedom units each powered by a low-cost, yet modified, hobby servo that we call the Super Servo. We have updated the internal electronics in the servo as well as created new mechanism designs so as to optimize efficiency and robustness.

Astrobotic Technology Inc. and Carnegie Mellon University’s Robotics Institute have found a way to use riding lawn-mower sized construction robots to prepare our Moon’s surface for a NASA outpost.

The goal of the project was to figure out how to reduce the disruption of Moon dust when outpost rockets land or take off. Since the Moon has no atmosphere to slow down the disrupted Moon dust, the dust presents a problem for the future outpost.

The report outlines several methods of reducing dust-spread by use of these Moon bots. In one method, the robots would build raised berms around the launch area. In the other method, the robots would pack native Moon material into a hard-packed landing surface.

This is exactly the type of work that tells the world we are serious about returning to The Moon. NASA’s current schedule is to have a Lunar outpost by 2020. Hopefully that doesn’t get pushed back or cut like other project have.
