Alliance Spacesystems Reaches Out To Mars With Robotic Arm Deployment
Pasadena - Jan 19, 2004 With the deployment of the Spirit Rover, a robotic arm built by Alliance Spacesystems is now in action. The robotic arm (formally known as the Instrument Deployment Device, or IDD) has five rotating joints and an extended length of more than one meter. The arm is mounted to the forward structure of the "Spirit" rover and was secured during launch, landing, and rover positioning by ASI-designed restraint mechanisms at the arm elbow and the instrument turret at its outboard end. Mechanisms developed by ASI for the arm include five unique actuators that articulate the arm and position scientific instruments, the two restraint mechanisms that unlatched after landing on the surface of Mars and provide passive restraint during rover maneuvers, contact sensors to detect proximity to targets of interest, and a complex flexprint interconnection system that traverses the rotating joints to service the electromechanical devices and instruments. ASI's robotic arm supports a package of four complex scientific instruments that will enable scientists to study rock structure, detect materials that may have formed in the presence of water, and define elemental structure. The package of instruments will expose the unaltered interiors of rocks to identify minerals containing iron and evaluate the composition and texture of rocks and soil at a microscopic scale. "The successful landing and deployment of MER is a tribute to the years of unrelenting effort by the talented and dedicated JPL team," said Rene Fradet, CEO of Alliance Spacesystems, Inc. "The thrill of being part of this mission and seeing an ASI robotic arm at work on another planet is extraordinary." ASI is a provider of mechanical systems for aerospace and commercial applications. ASI provides composite structures, robotics, mechanisms and mechanical analyses for systems operating in extreme environments. ASI's innovative products have seen use in interplanetary spacecraft, telecommunications and scientific satellites and challenging terrestrial applications.

Spirit Heading To 'Home Plate'
Pasadena CA (JPL) Jan 09, 2006Last week Spirit completed robotic-arm work on "El Dorado." The rover used all three of its spectrometers plus the microscopic imager for readings over the New Year's weekend. |
