Help NASA Design a Robot to Dig on the Moon


Digging on the Moon is a hard job for a robot. It has to be able to collect and move lunar soil, or regolith, but anything launching to the Moon needs to be lightweight. The problem is excavators rely on their weight and traction to dig on Earth. NASA has a solution, but is looking for ideas to make it better.

Once matured, robotic excavators could help NASA establish a sustainable presence on the Moon under the Artemis lunar exploration program, a few years after landing astronauts on the surface.

Engineers have tested various configurations of a Moon-digging robot called RASSOR – short for Regolith Advanced Surface Systems Operations Robot – in a large lunar simulant sand box at NASA’s Kennedy Space Center in Florida. Now, NASA is asking the public to help design a new bucket drum, the portion of the robot that captures the regolith and keeps it from falling out. The regolith can then be transported to a designated location where reverse rotation of the drum allows it to fall back out.
