DEVICE FOR WEIGHTLESSNESS OF ELEMENTS OF SPACE VEHICLES DURING GROUND TESTS Russian patent published in 2021 - IPC B25J5/00 B64G7/00 

FIELD: robotics.

SUBSTANCE: invention relates to robotics, namely to automatic mobile robots, and can be used to simulate weightlessness during ground tests for the functioning of moving elements of spacecraft, in particular the wings of solar panels. Device contains a mobile robotic platform on omnidirectional wheels, made with the ability to move in any direction and rotate around its axis. Each wheel of the mobile robotic platform is equipped with a separate electric drive, which is connected to a power source through the controller. A weight compensation device is attached to the platform. At the bottom end of the vertical support there is a ball support with the possibility of free movement along the horizontal support board, on which the device for determining the position of the support is fixed. The horizontal support board is fixed to the weight compensation device through a force sensor. The force sensor, the weight compensation device and the support post position detection device are connected to the controller and the power supply.

EFFECT: said invention allows weightlessness of spacecraft elements at the same time eliminating the inertia of the weightlessness element caused by the «effect of added masses».
