Abstract

The invention relates to manned aerospace space station equipment, and in particular relates to a space station extravehicular mobile robot system with redundant power supply. The system comprises a moving platform, an arc-shaped track system, a take-up and pay-off mechanism, a space station exposed platform cabin section and a six-axis mechanical arm, the arc-shaped track system is arranged between a space station main cabin section and the space station exposed platform cabin section, the moving platform is arranged on the arc-shaped track system, the six-axis mechanical arm is arranged on the moving platform, the movable platform can move along the arc-shaped track system, so that the six-axis mechanical arm can continuously reach all quadrants of the space station exposed platform cabin section; the take-up and pay-off mechanism is arranged at the bottom of the arc-shaped track system, connected with the moving platform and used for supplying power to the moving platform. The moving platform driven by a friction wheel is adopted as a base of the mechanical arm, so that the mechanical arm can be continuously reached and positioned in the full quadrant of the exposed platform, a datum point does not need to be replaced in the operation process, and the precision is easy to guarantee.

Description

technical field [0001] The invention relates to manned space station equipment, in particular to a mobile robot system outside the space station with redundant power supply. Background technique [0002] With the continuous development of aerospace technology, human activities in space exploration are also increasing. Space robots can autonomously or assist humans to explore the space environment, such as assisting astronauts to complete out-of-cabin operation tasks on the space station, patrolling and detecting on the surface of Mars, drilling and sampling on the surface of the moon, etc., and are useful assistants for human space activities. The operation of the task is even non-robotic, such as some dangerous operation tasks. The space station extravehicular robot is an important category of space robots, and it is also the most mature space robot developed and applied so far. The mobile serving system (Mobile Servicing System, MSS) of the extravehicular robot on the In...
