Zero gravity space product testing
Gravity is a huge problem when it comes down to testing space equipment in a realistic environment. Carbospacetech accomplishes to avoid gravity impact in testing with this revolutionary development. Reach the next level of zero gravity testing for space equipment with the ZeroG robot.
ZeroG uses different methods for compensating in the XY plane (horizontal) and Z axis (vertical). The basic principle for XY is to suspend the test object on a rope, and 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, ensures 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. Keeping force in the rope equal to mass of the test object times g and minimizing rope angle ZeroG is able to eliminate the impact of gravity.
