Nasa has a 'mini' rover that won't get stuck on distant moons and planets

, said: ‘When loose materials flow, that can create problems for robots moving across it. This rover has enough degrees of freedom that it can get out of jams pretty effectively.‘By avalanching materials from the front wheels, it creates a localised fluid hill for the back wheels that is not as steep as the real slope. The rover is always self-generating and self-organising a good hill for itself.

‘This enabled our team to use our robot as a robust laboratory tool and focus our efforts on exploring creative and interesting experiments without worrying about damaging the rover, service downtime, or hitting performance limitations.’ Andras Karsai, a PhD candidate at Georgia Tech’s School of Physics, added: ‘By creating a small robot with capabilities similar to the RP15 rover, we could test the principles of locomoting with various gaits in a controlled laboratory environment.‘In our tests, we primarily varied the gait, the locomotion medium, and the slope the robot had to climb.

The rear wheels wiggled from side-to-side, lifting and spinning to create a motion that resembles paddling in water. ‘If you want fast locomotion, we found that you should try to keep the material as solid as possible by tweaking the parameters of motion.’

It looks like a Fisher Price toy 😄

we need to leave the rest of the universe alone ... haven't we done enough damage here ?
