The robots are tested in box containing eight tons of simulated lunar regolith that is about 4 meters square and about one-half meter deep. In order to qualify for a prize, a robot must dig up and then dump at least 150 kg of regolith into a container in 30 minutes. The teams with the robots that move the most regolith will claim the three cash

Also the grain size distribution of the lunar regolith up to 1 m grains is created by combining the data from Apollo and Surveyor missions. In the experiments, gravel (2 mm--10 mm) is added to JSC-1A In addition, a math model of the ripping force is developed as a function of material density, which could be the basis of an instrumented-ripper technique for detailed mapping of …

1 day ago · Lunar regolith is being considered as the raw material for in-situ AM on the lunar surface. Several AM techniques based on different physical principles were tested on various lunar regolith simulants, showing promising results (Isachenkov et al., 2021). AM technologies, proposed for 3d-printing with lunar regolith, can be utilized for the

The device will use electrostatic separation of tribocharged grains to sort the material with minimal moving parts or contact with the grains. Due to the highly adhesive and abrasive nature of lunar regolith, this significantly increases the lifespan of the device and reduces its complexity relative to other grain separation concepts.
