Research and design an intelligent zero gravity space floating robot for Space Stations

Considering difficulties in the design of lightweight and autonomous zero gravity space floating robot inside Space Stations, referring to the characteristics of floating robots already in orbit on the International Space Station (ISS), as well as the needs of astronauts and space station operation and maintenance for floating robots, a 5Kg level lightweight floating robot using 3D printing and modular design is proposed. To achieve high-precision autonomous navigation and control in limited space of the Space Stations, a closed-loop trajectory planning and control method based on visual slam and model predictive control, is proposed for our intelligent floating robot. By using a zero-gravity suspension device, ground tests proved the correctness of hardware and software design, including structural, propulsion, navigation, control and human-computer interaction design. In the future, it can be deployed to the China Space Station.
