Gota concept started as a small aerial surveillance UAV or a small telemetry platform to access difficult areas. The objective was a small vehicle able to land everywhere and provide valuable information or be used as a communication beacon.
The idea is to change the attitude using the inertia of rotating cylinders in the outside of each leg. Three legs are used to ensure stability on any landing surface.
This concept had a big drawback: if it was to be manoeuvring in air, the added weight would increase too much the power needed. A multi-copter configuration outperforms this concept in air. In space, however, this concept may be useful.
