CHIMP (CMU Highly Intelligent Mobile Platform)

Tartan Rescue of Carnegie Mellon University in the US is entering CHIMP, which took third place in the 2013 DARPA Robotics Challenge Trials. CHIMP has a near-human form factor designed for hazardous environments and is fitted with a full, 360-degree sensor suite to create a 3D model of its surroundings.

CHIMP has tank-like treads instead of feet and treads on its elbows as well. It can drive on all fours for tricky terrain, and stand up on two legs when it needs to.

HRP-2+ boasts human-like bipedal motion over rough terrain. It has the ability to lay down and get up again, fall safely, clear a narrow passage and manipulate objects while supporting itself with one hand. A bonus: it also performs traditional Japanese dance.

HRP-2+ is the upgraded version of the original HRP-2 built in 2002.

6 of 24 Team Hector

Johnny 05

Germany's Team Hector has made a bit of a nod to "Short Circuit" with Johnny 05 in name, if not in appearance. Johnny 05 has a modular design that means its components are easy to remove, repair and replace. The bipedal robot is based on software created by DRC Team ViGIR (TORC Robotics, TU Darmstadt, Virginia Tech, Oregon State University, Cornell University and Leibniz University Hanover). Johnny 05 is based on the Thormang hardware made by South Korea's Robotis.

Weight: 55kg (121lb)

7 of 24 Team HKU


Team HKU of Hong Kong University is entering Atlas, a bipedal robot with one very long arm. The team specialises in robot vision, motion planning, programming and control, human-machine interaction and robotic hardware. The team is entering a tetherless version of Boston Dynamics' hydraulically powered Atlas robot.

Year of birth: 2015

Height: 190cm (6.2ft)

Weight: 175kg (386lb)

10 of 24 Team KAIST


Since the rules of the competition allow robots with the same hardware to enter, so long as the software is different, there are some double-ups. Team KAIST of South Korea designed HUBO (HUmanoid RObot), which has been a project of the institute since 2002. The team is entering the latest version of the robot, and has redesigned it to be more powerful and capable. They have rewritten the walking algorithm, and the robot can also move to a kneeling position for wheeled motion, via wheels attached to its knees.

Year of birth: 2014

Height: 180cm (5.9ft)

Weight: 80kg (176lb)

11 of 24 Team MIT

Helios (Atlas)

Team MIT's version of Atlas, Helios, is a very odd-looking version of the robot, with extra-long, modified arms with different grippers on each hand for completing a variety of tasks.

Year of birth: 2013

Height: 195cm (6.4ft)

Weight: 182kg (401lb)

12 of 24 Team NEDO-Hydra


Hydra, from Team NEDO-Hydra of Japan, is a collaborative effort across four universities. The University of Tokyo developed the hardware, which has 41 points of articulation.

14 of 24 Team NimbRo Rescue


Team NimbRo Rescue from the University of Bonn, Germany, departs from the bipedal model with the wheeled Momaro. Momaro runs on four compliant legs that end in pairs of directly driven, steerable wheels, which allows for omnidirectional driving on uneven terrain. To overcome higher obstacles, the individual legs can lift and climb. The rotating body on this base is equipped with two arms, each ending in four individually controllable fingers with two joints each. A sensor head with a rotating 3D laser scanner, eight RGB-D cameras and three full HD colour cameras allow the robot to see its surroundings in detail.

15 of 24 JPL/NASA


NASA's Jet Propulsion Labs is doing away with humanoid altogether with the RoboSimian, a modular crawling robot. It has 28 points of articulation divided among four identical legs for the purposes of simplifying design, fabrication and maintenance, but the resulting platform is dextrous and customisable.

Weight: 180kg (397lb)

21 of 24 Team VALOR


Escher is a robot wholly designed, fabricated and assembled by Team VALOR, a team of engineering students at Virginia Tech. Because it is lightweight for its size, it can operate untethered for up to two hours. It features a multi-spectral sensor suite for surveying its environment, and a perception system allows it to identify obstacles and tools, which in turn allows the bipedal robot to operate semi-autonomously.
