HOUSTON—Astronauts flexed the giant arms of the international space station’s new robot for the first time—testing the brakes and manoeuvring the appendages into position for a spacewalk tonight.
All the brakes on the Canadian-built robot passed the test except for one in the wrist joint of its left arm.
That brake slipped a tad more than engineers wanted, but officials weren’t concerned about the performance of the robot, called Dextre.
