Boston Dynamics is an engineering and robotics design company that is best known for the development of BigDog, a quadruped robot designed for the U.S. military with funding from Defense Advanced Research Projects Agency (DARPA),[1][2] and DI-Guy, software for realistic human simulation. Early in the company's history, it worked with the American Systems Corporation under a contract from the Naval Air Warfare Center Training Systems Division (NAWCTSD) to replace naval training videos for aircraft launch operations with interactive 3D computer simulations featuring DI-Guy characters.[3]

Marc Raibert is the company's president and project manager. He spun the company off from the Massachusetts Institute of Technology in 1992.[4]

On 13 December 2013, the company was acquired by Google X, where it will be managed by Andy Rubin.[5] Immediately before the acquisition, Boston Dynamics transferred their DI-Guy software product line to VT MÄK, a simulation software vendor based in Cambridge, Massachusetts.[6]

Products[edit]

BigDog[edit]

Main article: BigDog

BigDog is a quadrupedal robot created in 2005 by Boston Dynamics, in conjunction with Foster-Miller, the Jet Propulsion Laboratory, and the Harvard University Concord Field Station.[7] It is funded by the DARPA[8] in the hopes that it will be able to serve as a robotic pack mule to accompany soldiers in terrain too rough for vehicles. Instead of wheels, BigDog uses four legs for movement, allowing it to move across surfaces that would defeat wheels. Called "the world's most ambitious legged robot", it is designed to carry 340 pounds (150 kg) alongside a soldier at 4 miles per hour (6.4 km/h; 1.8 m/s), traversing rough terrain at inclines up to 35 degrees.[9]

Legged Squad Support Systems (LS3) is similar to the BigDog.[10]

Cheetah[edit]

The Cheetah is a four-footed robot that gallops at 28 miles per hour (45 km/h; 13 m/s), which as of August 2012 is a land speed record for legged robots. The previous record was 13.1 miles per hour (21.1 km/h; 5.9 m/s), set in 1989 at MIT. Cheetah development is funded by DARPA's Maximum Mobility and Manipulation program.[citation needed] This robot has an articulated back that flexes back and forth on each step, thereby increasing its stride and running speed, much like the animal does. The original Cheetah robot runs on a high-speed treadmill in the laboratory where it is powered by an off-board hydraulic pump and uses a boom-like device to keep it running in the center of the treadmill. A free-running Cheetah that will operate more naturally in the field, named the WildCat, was unveiled to the public on October 3, 2013.[11]

A similar but independently developed robot also known as Cheetah is made by MIT's Biomimetic Robotics Lab,[12] which, by 2014, could jump over obstacles while running.[13][14]

LittleDog[edit]

LittleDog is a small quadruped robot developed for DARPA by Boston Dynamics for research. Unlike BigDog, which is run by Boston Dynamics, LittleDog is intended as a testbed for other institutions. Boston Dynamics maintains the robots for DARPA as a standard platform.[15][16]

LittleDog has four legs, each powered by three electric motors. The legs have a large range of motion. The robot is strong enough for climbing and dynamic locomotion gaits. The onboard PC-level computer does sensing, actuator control and communications. LittleDog's sensors measure joint angles, motor currents, body orientation and foot/ground contact. Control programs access the robot through the Boston Dynamics Robot API. Onboard lithium polymer batteries allow for 30 minutes of continuous operation without recharging. Wireless communications and data logging support remote operation and data analysis. LittleDog development is funded by the DARPA Information Processing Technology Office.[17]

RiSE[edit]

RiSE is a robot that climbs vertical terrain such as walls, trees and fences, using feet with micro-claws to climb on textured surfaces. It changes posture to conform to the curvature of the climbing surface and its tail helps it balance on steep ascents. RiSE is 0.25 m long, weighs 2 kg, and travels 0.3 m/s.[18]

Each of RiSE's six legs is powered by a pair of electric motors. An onboard computer controls leg motion, manages communications, and services a variety of sensors, including joint position sensors, leg strain sensors and foot contact sensors.

Boston Dynamics developed RiSE in conjunction with researchers at University of Pennsylvania, Carnegie Mellon, UC Berkeley, Stanford, and Lewis and Clark College. It was funded by DARPA.

SandFlea[edit]

SandFlea is a small robot capable of jumping 30 feet (8 m) straight up. This wheeled robot weighs 11 pounds (4.9 kg), and drives like a remote-controlled car on flat surfaces.[19]

The robot uses gyro stabilization to stay level during flight, to provide a clear view from the onboard camera, and to ensure a smooth landing. Sand Flea can jump about 25 times on one charge. Boston Dynamics is developing Sand Flea with funding from the US Army’s Rapid Equipping Force (REF). Earlier versions of Sand Flea were developed by Sandia National Laboratory with funding from DARPA and JIEDDO. [20]

PETMAN[edit]

PETMAN (Protection Ensemble Test Mannequin)[21] is a bipedal device constructed for testing chemical protection suits. It is the first anthropomorphic robot that moves dynamically like a real person. Much of its technology is derived from BigDog.[22]

Unlike previous suit testers that had a limited repertoire of motion and had to be supported mechanically, PETMAN balances itself and moves freely; walking, bending and doing a variety of suit-stressing calisthenics during exposure to chemical warfare agents. PETMAN also simulates human physiology within the protective suit by controlling temperature, humidity and sweating, all to provide realistic test conditions. The PETMAN system was delivered to the user’s test facility where it is going through validation experiments. Boston Dynamics' partners for the program are MRIGlobal, Measurement Technologies Northwest, Smith Carter CUH2A (SCC), SRD, and HHI Corporation. [23]

LS3[edit]

Legged Squad Support System (LS3), also known as AlphaDog, is a militarized version of BigDog. It is ruggedized for military use, with the ability to operate in hot, cold, wet, and dirty environments.

LS3 is a rough-terrain robot designed to go anywhere Marines and Soldiers go on foot, helping carry their load. Each LS3 carries up to 400 lbs of gear and enough fuel for a 20-mile mission lasting 24 hours. LS3 automatically follows its leader using computer vision, so it does not need a dedicated driver. It also travels to designated locations using terrain sensing and GPS. LS3 began a 2-year field testing phase in 2012. LS3 is funded by DARPA and the US Marine Corps. Boston Dynamics has assembled an extraordinary team to develop the LS3, including engineers and scientists from Boston Dynamics, Carnegie Mellon, the Jet Propulsion Laboratory, Bell Helicopter, AAI Corporation and Woodward HRT. [24]

Atlas[edit]

Main article: Atlas (robot)

The Agile Anthropomorphic Robot "Atlas" is a 6-foot (1.8 m) bipedal humanoid robot, based on Boston Dynamics' earlier PETMAN humanoid robot, and designed for a variety of search and rescue tasks.[25]

Atlas is a high mobility, humanoid robot designed to negotiate outdoor, rough terrain. Atlas can walk bipedally leaving the upper limbs free to lift, carry, and manipulate the environment. In extremely challenging terrain, Atlas is strong and coordinated enough to climb using hands and feet, to pick its way through congested spaces. Articulated, sensate hands will enable Atlas to use tools designed for human use. Atlas includes 28 hydraulically-actuated degrees of freedom, two hands, arms, legs, feet and a torso. An articulated sensor head includes stereo cameras and a laser range finder. Atlas is powered from an off-board, electric power supply via a flexible tether. Several copies of the Atlas robot are being provided as Government Furnished Equipment for the DARPA Robotics Challenge program with delivery scheduled in the summer of 2013. [26]

RHex[edit]

RHex is a six-legged robot with inherently high mobility. Powerful, independently controlled legs produce specialized gaits that devour rough terrain with minimal operator input. RHex climbs in rock fields, mud, sand, vegetation, railroad tracks, telephone poles and up slopes and stairways.

RHex has a sealed body, making it fully operational in wet weather, muddy and swampy conditions. RHex's remarkable terrain capabilities have been validated in government-run independent testing. RHex is controlled remotely from an operator control unit at distances up to 700 meters. Visible/IR cameras and illuminators provide front and rear views from the robot. [27]
