After some power troubles with a space robot named Dextre, astronauts on the Shuttle Endeavor finally gained the upper hand late in the weekend.
Astronauts were able to connect the arms to the shoulders, but not after they had to use brute force and a pry bar to get one of the robot's arms off the transport bed. Two of the bolts wouldn't budge at first, but eventually the bolts gave way. Once fully assembled, Dextre will stand 12 feet and weigh 3,400 pounds. A third spacewalk, on Monday night, will provide Dextre with a tool holster.
