MDA US Systems, a division of MDA managed by SSL, has been recognized by Nasa’s Johnson Space Center for its “outstanding support” of a robotic upgrade to the International Space Station’s power system which took place in January.

The MDA team based in Houston played a critical role in planning and validating the robotic maneuvering both before and during the mission.

Nasa JSC ground controllers used the 15-degrees-of-freedom Special Purpose Dextrous Manipulator (Dextre) arm to install six new 430-pound lithium-ion batteries in two power channel integrated electronics assembly pallets.

Dextre first removed 12 older and depleted 740-pound nickel-hydrogen batteries from the pallets, nine of which were put on the Japanese H-II Transfer Vehicle’s external pallet to burn up on re-entry with it.

Nasa places order with SSL for robotic spacecraft which will fix satellites in orbit

New craft will be used to service satellites out in space

Nasa has placed an order with Space Systems Loral for a robotic spacecraft which will go and fix satellites while in orbit.

Nasa calls it the Restore-L servicing mission, and it is designed to demonstrate the ability to extend the life of a satellite in Low Earth Orbit. Scheduled launch is in 2020.

The Restore-L spacecraft will use robotics to grasp, refuel and relocate an existing US government satellite already in LEO orbit with the goal of demonstrating tools, technologies and techniques that can be implemented on future government and commercial missions.

Carnegie Mellon demonstrates autonomous helicopter and ground vehicle technology to US military

Carnegie Mellon demonstrated how autonomous aerial and ground vehicles can work together

Robotics and automation experts at one of the world’s leading universities have demonstrated autonomous ground vehicles and aircraft with “new collaborative capabilities for keeping warfighters safe”.

Carnegie Mellon University (CMU) and Sikorsky, A Lockheed Martin Company, using a UH-60MU Black Hawk helicopter enabled with Sikorsky’s Matrix Technology and CMU’s Land Tamer autonomous Unmanned Ground Vehicle (UGV), recently participated in a joint autonomy demonstration that they say proved the capability of new, ground-air cooperative missions.

Such missions could prevent warfighters’ exposure to hazardous conditions, such as chemically or radiologically contaminated areas, say the experts. [Read more…] about Carnegie Mellon demonstrates autonomous helicopter and ground vehicle technology to US military
