A 3-axis autonomous gravity offloading device located within a lunar simulant chamber.
Dr. Paul van Susante
The Infrared Gravity Offloading (IRGO) device is an active 3-axis crane inside the PSTDL lunar simulant sandbox that continuously positions itself over an object with a constant upward force simulating lunar gravity by tracking with an infrared LED.
X & Y axis are positioned by a control loop referencing the relative offset of the LED
Z axis will provide continuous upward force to simulate lunar gravity
Stepper motors for accuracy
Controlled by IR tracking or manual control with keyboard/controller
Only requirement is that the tether is attached to the center of gravity.
