What is Boston Dynamics and why does Google want robots?

Google’s latest acquisition is one of the most advanced robotics companies in the world, and makes robots for the US military


Google’s recent acquisition of Boston Dynamics marks its eighth robotics purchase in the past six months, showing Google’s “moonshot” robotics vision is more than just a pet project.

Boston Dynamics is the most high-profile acquisition, however, instantly adding world-leading robotics capability, including robots that can walk all on their own, to Google’s arsenal – as well as significant links to the US military – conjuring images of Skynet and the artificial intelligence-led robot uprising straight out of the 1984 film The Terminator.

What is it?
Boston Dynamics is an engineering and robotics design company that works across a wide range of computer intelligence and simulation systems, as well as large, advanced robotic platforms.

The company was created as a technology spin-off from Massachusetts Institute of Technology by Prof Marc Raibert in 1992, then the founder and lead researcher of the Leg Lab – a research group focussed on systems that move dynamically, including legged robots.

What does it do?
Raibert describes the Boston Dynamics team as “simply engineers that build robots”, but in reality Boston Dynamics is much more than that.

Its robotics work is at the forefront of the technology creating the self-proclaimed “most advanced robots on Earth” particularly focused around self-balancing humanoid or bestial robots.

Funding for the majority of the most advanced Boston Dynamics robots comes from military sources, including the US Defence Advanced Research Projects Agency (Darpa) and the US army, navy and marine corps. The terms of contracts currently held by Boston Dynamics with military bodies are unknown, although Google has committed to honouring existing contracts, including recent $10.8m funding from Darpa.



Funded by Darpa and the US army, BigDog is Boston Dynamics’ most famous robot, a large mule-like quadruped that walks around like a dog, self balancing and navigating a range of terrain.

Standing about 76cm tall, 91cm long and weighing 109kg, BigDog is an autonomous system powered by an engine and controlled by on-board computer system processing a series of sensors that monitor joint position, joint force, ground contact, ground load, a gyroscope, LIDAR and a stereo vision system.

BigDog is capable of running at 4mph, climbing 35 degree slopes and carrying 155kg loads. Its derivative, the Legged Squad Support Systems, increases BigDog’s carrying capacity to 181kg with a 20-mile range.



The world’s fastest robot, Cheetah, runs like a big cat at over 29mph – faster than 100m world champion sprinter Usain Bolt. Like a real cheetah, the robot has an articulated back that flexes back and forth with each step, increasing its stride length and running speed.

Funded by Darpa’s Maximum Mobility and Manipulation program, in its current implementation Cheetah runs tethered on a treadmill, powered by a separate hydraulic pump.

The next generation of the Cheetah platform designed to operate untethered, the WildCat, recently entered initial testing.



One of Boston Dynamics’ latest robots funded by Darpa, Atlas is a humanoid robot designed to negotiate outdoor, rough terrain in a bipedal manner, while being able to climb using hands and feet as a human would.

Atlas is will be equipped with articulated hands with sensors enabling the robot to use tools designed for humans, as well as an articulated sensor head including stereo cameras and a laser range finder. The robot currently is powered by a tethered electric power supply, and controlled remotely.

Other robots in the Boston Dynamics stable include Petman, a robot that tests humanoid chemical protective clothing; the wheeled SandFlea robot that can leap small buildings; a small six-legged robot capable of traversing rough terrain called RHex; and the RiSE robot capable of climbing vertical walls, trees and fences using feet with micro-claws.
