Dextre Has Shoulder Problems

The $200 million robot, Dextre, developed by the Canadian Space Agency has experiencing a problem with one of it's shoulder joints since being moved in preparation for a Thursday night spacewalk. The shoulder is apparently returning an "unknown position" message, prompting engineers to consider a software patch. This setback comes after a faulty cable threatened the robot earlier in the mission. Dextre is designed to perform regular maintenance tasks outside the International Space Station, things like replacing batteries and wires. The aim is to reduce the number of dangerous space walks that astronauts must now perform. CTV has more here.
