Zero gravity space product testing
Gravity is critical for testing space equipment in a realistic environment. By using this revolutionary simulation tool, CarboSpaceTech aims to avoid gravity impact during testing. Reach the next level of zero gravity testing for space equipment with the ZeroG robotic arm.
CarboSpaceTech’s ZeroG uses different methods for compensating in the XY plane (horizontal) and Z axis (vertical). ZeroG’s basic principle for XY suspends the test object on a rope, making sure that this rope is as vertical as possible during the test. A sensor measures this rope angle and robot manipulator, driven by a “closed loop” control system. Thus ensuring minimal deviation from true vertical. Prior to testing, a calibration is done by suspending a mass that is not affected by external forces. Using this mass as plumb line ZeroG can automatically find true vertical for multiple points in the working area. In the Z-Axis (vertical) ZeroG ensures constant force by measuring the force in the rope and actively controlling the rope length using a high-speed winch. Therefore, ZeroG is able to eliminate the impact of gravity by keeping the force in the wire equal to the mass of the test object multiplied by G and minimizing the rope angle.
