Testing of station's Dextre robot gets underway
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: March 16, 2008

The Canadian Space Agency's $209 million space station robot, Dextre, was subjected to joint-by-joint brake tests today to make sure the gangly mechanical handyman's 11-foot-long arms are working properly. All but one of the joints passed the first round of tests and managers said the one that didn't was only slightly out of limits and not a major concern.

"All the diagnostics ... were successfully accomplished," said Pierre Jean, acting space station program manager for the Canadian Space Agency. "In the last couple of hours, we went into the next phase of testing, or really more calibration if you will, which were the brake run-in checks. The brake run-in checks, basically, is a special test, or checkout, to ensure the brakes are operating nominally. You could think of it essentially as if you start your car and put your foot on the brake and you accelerate a little bit. You don't want the car to move. That's exactly what we tried to do.

"In this case, we know what force to apply and we did exactly that with Dextre, going through each of the arms, arm 1 followed by arm 2, each joint, joint by joint, basically stepping up the voltage to about 20 volts until we got a .5-amp current and then seeing what motion, or displacement, we got on the joints.

"Arm 1 passed, the highest slippage we had in any of the joints was 4.1 degrees," Jean said. "Arm 2, unfortunately with one of the joints, the wrist-pitch joint, we're right on the margin. The generic number we were trying to target was 10.3 degrees ... of slippage. However, we were getting 10.4."

Repeating the test, engineers saw some improvement and Jean said he was confident the issue would be resolved.

"Basically, both arms performed extremely well during the brake run-in tests with the exception of one joint," he said. "We're not too concerned about it, but we just want to make sure we meet the requirements we have to meet."
