Google-owned SCHAFT robot wins DARPA Robotics Challenge Trials

- 0 comments
The Google-owned Japanese robotics company SCHAFT has won the DARPA Robotics Challenge Trials by a wide margin. It scored 27 out of 32 points, beating its nearest competitor IHMC Robotics by seven points. Coming up third was Tartan rescue with 18 points, and MIT following that with 16 points.


The contest took place Dec. 20-21 at the Homestead-Miami Speedway, where 16 teams from around the world did their best to guide their robots through a series of tasks. The robots were to be programmed in such a way that they could be guided by simple commands issued by a non-expert, e.g., "Open the door" or "Clear away the debris in front of you."

The object of the challenge, DARPA says, was to create a robot that could stand in for humans in disaster and emergency zones. In all, eight tasks were included: drive a vehicle; walk across rubble; remove debris; open a door and walk through it; climb a ladder and cross an industrial walkway; break a concrete panel with a tool made for humans; find and close a valve; and connect a fire hose to a pipe and open the valve.

The SCHAFT entry is a 216-pound robot based on the company's preexisting HRP-2 model. It is bipedal and stands 4.8 feet tall with a 4.3-foot wingspan. Business Insider says the SCHAFT robot is "ten times stronger than any other" in the DRC Trials.

Check out the SCHAFT robot performing the eight DRC Trials tasks in the sped-up video below. The tasks were actually performed at a much lower speed, as was the case for all of the robots in the competition. The suspension cables you see are for saving the robot in case of a fall; it is actually self-supporting and self-propelled.

The DRC Trials are the last stop along the way before next year's DRC Finals, where qualified robots will compete for DARPA's grand prize of $2 million. The Finals are to take place in December 2014.

NASA unveils Valkyrie 'robot' for DARPA Robotics Challenge

- 0 comments

DARPA has been hosting a Robotics Challenge since last year that challenged some participants to create robots that can be used in the real world. The official name for the Valkyrie robot given to it by NASA is R5. The bot stands 1.9 meters tall and weighs in at 125 kilograms. The robot has 44 degrees of freedom and is powered by batteries.

The robot was created in cooperation with the NASA Johnson Space Center in Houston, the University of Texas, and Texas A&M universities. Funding for the robot was granted by the State of Texas. The first competition for the DARPA robotics contest will happen later this month.

The Valkyrie robot will be competing against five other Track A teams that have developed their own robots. The DARPA contest requires the robots to walk over uneven terrain, climb a ladder, use tools, and drive a vehicle. One of the goals of the DARPA contest is to create robots that can take over from humans in certain situations without needing any special accommodations, which is why the robot is humanoid.

The arms of the robot have seven degrees of freedom with actuated wrists and hands. Each hand has three fingers and a thumb. The head can tilt and swivel around while the waist is able to rotate. The legs themselves offer the robot six degrees of freedom and end with feet that have six-axis force-torque sensors. The robot has a battery in its backpack good for an hour of use per charge. The designers of Valkyrie said that they leveraged some of the tech and knowledge gained in developing Robonaut over the years. Valkyrie even has a glowing circle in its chest that looks like Iron Man’s Arc reactor.
