KAIST's DRC-HUBO Wins the DARPA Robotics Challenge 2015
DRC-HUBO finished all eight assignments in less than 45 minutes, taking first place among 24 international teams and claiming the USD 2 million prize offered by a US defense research agency.
The Robotics Challenge Finals 2015 hosted by the US Defense Advanced Research Projects Agency (DARPA) took place on June 5-6, 2015 at the Fairplex in Pomona, California.
Team KAIST of the Republic of Korea led by Professor Jun-Ho Oh of the Mechanical Engineering Department at the Korea Advanced Institute of Science and Technology (KAIST), Professor In-So Kweon of the Electrical Engineering Department, and researchers from Rainbow Co., the university’s spin-off company that builds the robots, won the DARPA Finals. The team received USD 2 million as a prize.
The DARPA’s Robotics Challenge (DRC) promotes a competition of robot systems and software teams which seek to develop robots capable of assisting humans in responding to natural and man-made disasters such as the Fukushima Daiichi nuclear incident in 2011. The DRC consists of three competitions: a software-based Virtual Robotics Challenge which took place in June 2013; the Robotics Challenge Trials in Homestead, Florida, in December 2013; and the Finals in June 2015.
A total of 24 teams from universities and private and public research institutes from Korea, the US, Hong Kong, Germany, Japan, and Italy participated in the Finals. The participating teams had to finish eight assignments in 60 minutes, during which their robots were untethered and operated wirelessly without communication from their engineers.
Each team was assigned a series of tasks: they included driving a vehicle, getting out of a vehicle, opening a door, turning a valve, drilling a hole in a wall, a surprise task such as pushing a button or turning on a switch, walking over rubble or debris, and climbing stairs. Robots scored a point each time they completed their missions. To win, a team had to complete all the tasks successfully in the shortest amount of time possible.
Team KAIST completed the entire course in 44 minutes and 28 seconds, followed by the Institute of Human and Machine Cognition (IHMC) Robotics in Pensacola, Florida in 50:26, and Team TARTAN Rescue of the National Robotics Engineering Center at Carnegie Mellon University in 55:15.

KAIST's HUBO Ready for DARPA's Robotics Challenge Trials
When walking on muddy or bumpy roads, the two arms of DRC-HUBO become extra legs, enabling stable and agile movements.
The Humanoid Robot Research Center (HUBO Lab, http://hubolab.kaist.ac.kr) at the Korea Advanced Institute of Science and Technology (KAIST) and Rainbow Co., a spin-off venture company of the university, unveiled a new model of HUBO that will be entered in an international robotics competition scheduled later this year.
The competition is hosted and sponsored by the US Defense Advanced Research Projects Agency (DARPA), which is called the DARPA Robotics Challenge (DRC). Kicked off in October 2012, the DRC’s goal is to spur the development of advanced robots that can assist humans in mitigating and recovering from future natural and man-made disasters.
KAIST’s humanoid robot, HUBO, was originally created by Jun-Ho Oh, a distinguished professor of the Department of Mechanical Engineering, in 2004. Since then, the robot has gone through technological advancements, with the latest version of HUBO II released in 2012. So far, 12 HUBOs have been exported for further studies in robotics to universities, research institutes, and private companies in the US, China, and Singapore.
In tandem with Rainbow Co. (www.rainbow-robot.com), Professor Oh and his research team recently developed DRC-HUBO, which will compete as Team DRC-HUBO led by Drexel University at the DRC trials to be held in December 2013. Team DRC-HUBO is consisted of KAIST and nine US institutions.
DRC-HUBO is designed to perform difficult but essential activities required when responding to disaster scenes. The robot will have to fulfill eight tasks assigned by the DRC at the upcoming event such as driving a utility vehicle, walking across rough terrain, climbing a ladder, and using hand tools.
Unlike the previous models of HUBO, DRC-HUBO boasts several distinctive, enhanced features. Chief among them is the way the robot interacts with the external environment. Without complex sensors installed throughout the body, DRC-HUBO can control each joint of the arms and legs in compliance with the dynamics dictated by the external environment.
For example, when DRC-HUBO is faced with a rock falling from above while climbing up a ladder, the robot’s arms and legs naturally give in to the force of external changes. Accordingly, as the robot dodges the rock, its body and joints smoothly sway to absorb shock so that the fingers can keep a tight grip on the ladder, and the feet are planted firmly on the rail of the ladder, not losing balance.
In addition, DRC-HUBO can switch from bipedal to quadrupedal walking and vice versa. This provides the robot with greater stability to walk on uneven terrain or to climb up a hill. The robot’s arms and legs are elongated to better meet the challenges demanded by the DRC competition. DRC-HUBO’s two arms swing back and forth to form legs when necessary, thereby walking freely backwards and forwards.
The robot has gotten stronger grip as well. The right hand has four fingers (with one triggering finger that operates independently from the other three fingers), and the left hand has three fingers. All three fingers on both hands are actuated synchronously for gripping. The fingers are sophisticated enough to steer the wheel of a vehicle or grab a ladder to climb up, and strong enough to hold 15 lbs in one hand.
“With a full 34 degrees of freedom (DOF), DRC-HUBO stands 4.7 ft tall and weighs 120 lbs. All in all, the robot has been improved and extensively refurbished from the past models of HUBOs to compete at the DRC Trials. It has better vision and coordination. The legs and arms have become stronger,” said Professor Oh.
“Although the robot is still a prototype, it has important capabilities that can be utilized in advancing humanoid robots in general. One example is the way its arms can be used as extra legs to support the robot’s body, offering more flexibility in providing aid to humans.”
