- The Lyndon B. Johnson Space Center in Houston, Texas, is developing the Active Response Gravity Offload System (ARGOS) to simulate reduced gravity environments, such as Lunar, Martian, and microgravity, using a large scale, full motion robotic system.
- ARGOS supplies continuous offload of a portion of a person’s (or dynamic object’s) weight during dynamic motions such as walking, running, and jumping.
- ARGOS follows the person’s (or object’s) motion in the horizontal and vertical directions to maintain a vertical offload force.
- Rotational motion is accommodated by the ARGOS/payload interface mechanism.
- A fully realized ARGOS facility will be capable of supporting surface operation studies, suit and vehicle requirements development, suit and vehicle design evaluation, and training with both suited and shirt-sleeved participants.
- Such a facility will be capable of offloading the weight of rovers and robots for testing in simulated reduced gravity environments.
- ARGOS technology is intended to support testing, development, and training for future missions to Near Earth Asteroids, Micro-gravity environments, the Moon, Mars, or any other destination.
- The project philosophy has been to design, fabricate, test, and then improve.
- The knowledge gained from this iterative approach has matured the project designs and requirements.
- The current steel structure was built to accommodate movement in all three directions of motion (one vertical and two horizontal).
- Dimensions are 41’ x 24’ x 25’ tall.
