The Robots Had to Drive, Climb Stairs and Open a Door

1. Competition Goals

The DARPA Robotics Challenge was established to spur the development of semi-autonomous ground robots capable of performing complex tasks in dangerous environments. Funded by the US Defense Advanced Research Projects Agency, the multi-year program aimed to improve societal resilience against future disaster scenarios. Program manager Gill Pratt emphasized that the initiative sought to push robotics technology past existing limitations toward practical utility. Participating teams spent months preparing their hardware and software for the rigorous trials.

The program progressed from virtual simulations to live hardware competitions.

2. Disaster Tasks

The final competition required robots to complete eight specific disaster-response tasks within a strict time limit. Machines had to drive a utility vehicle, walk across uneven rubble, remove debris blocking an entryway, and open a building door. Additional challenges included climbing an industrial ladder, cutting through a concrete panel with a power tool, locating and closing a valve near a leaking pipe, and connecting a fire hose. Operators faced degraded communication links simulating real disaster conditions.

Competitors had to execute all tasks with minimal human intervention.

3. Preliminary Trials

Initial live trials took place in Florida during December 2013, where sixteen teams tested their machines on preliminary obstacle courses. During these trials, robots relied heavily on continuous teleoperation from human controllers for the majority of actions. The top eight performing teams earned direct DARPA funding to support their ongoing development for the final event. Additional self-funded teams also qualified to compete in the upcoming championship phase.

Successful teams advanced to the final championship competition.

4. Finals Gathering

On June 5 and 6, 2015, twenty-five of the world's top robotics organizations gathered at the Fairplex in Pomona, California. Competitors vied for a total prize pool of $3.5 million while attempting the simulated disaster-response course. Many teams utilized the Boston Dynamics Atlas humanoid platform provided through DARPA funding programs. Other organizations brought custom-built bipedal or quadrupedal machines tailored to the specific course requirements.

The championship event commenced with high public and scientific interest.

5. Robot Falls

Some robots fell while attempting the course, and other runs stopped when a machine could not complete a task. The competition rules accounted for interventions and the time spent on them. Teams worked on their machines between attempts. Results depended on completed tasks and elapsed time rather than the appearance of a robot during an isolated demonstration.

Each completed task contributed to the final competition result.

6. Winning Performance

At the conclusion of the event, three separate teams achieved a perfect score of eight completed tasks. Judges broke the tie by evaluating the total completion time recorded by each successful robot. First place was awarded to Team KAIST from South Korea with their DRC-Hubo robot. The winning machine completed all required disaster tasks with a total time of 44 minutes and 28 seconds.

Team KAIST secured the grand prize of $2 million.

7. Podium Finishes

Second place in the competition went to the Institute for Human and Machine Cognition for their Running Man platform. Tartan Rescue from the Carnegie Mellon National Robotics Engineering Center secured third place with their Chimp robot. Notably, the IHMC Running Man robot fell over backward while waving to the crowd immediately after successfully completing all eight tasks. Despite the post-completion fall, its official score remained valid.

The top three teams completed the challenging obstacle course successfully.

8. Program Legacy

Team KAIST’s DRC-HUBO won the 2015 finals in Pomona and the two-million-dollar first prize. The robot could move on wheels while kneeling as well as use its legs, within a competition that required tasks such as opening a door and climbing stairs. The final rankings recorded performance under those event rules; the teams had not carried out an actual disaster-site rescue during the competition.

KAIST completed the contest’s tasks and won the first prize.
