Schaft, a robot built by a Japanese team, performs the drill task, which challenged the robots to pick up a tool, walk across the floor and use the tool to cut into a wall at the appropriate target.
The Japanese robot easily won the overall two-day challenge, grabbing 27 out of a possible 32 points.
Gill Pratt, a DARPA program manager, said Team Schaft did so well at the competition because it's team members began to work on their robot earlier and more seriously than all the other teams. He noted that they did their homework and it paid off for them.
Team Schaft built both the hardware and the software for the challenge.
