Boston Dynamic’s Quadruped RobotsBen Reed
Introduction•Boston Dynamics was founded in 1992•Engineering company that originated as a
spinoff form MIT•Specialize in robotics and human
simulation software•Funded largely by DARPA (Defense
Advanced Research Projects Agency)
Quadruped Robots•Quadruped: four legged•5 different quadruped robots•They are all similar in some respects•All unique in other respects
Quadruped Robots Con’tRobot Capacity Range Weight Primary Use
BigDog 340 lbs 6.2 miles 240 lbs Carry Equipment
LittleDog N/A 30 minutes continuous operation
N/A Study movement
LS3 400 lbs 20 miles 850 lbs Carry equipment (Marine Corps)
WildCat unknown unknown unknown
Study movement, Increase speed of robotic movement
Technological Advances• Rough terrain capable
▫BigDog (video)▫LS3
• Advanced autonomy ▫BigDog▫LS3 (video)▫WildCat
• Record holding speed▫Cheetah (video)▫WildCat (video)
• Advanced study of locomotion and movement▫LittleDog (video)
A Closer Look at BigDog• Engine
▫ Leopard go-kart engine▫ One cylinder▫ Two stroke▫ Water cooled
• Hydraulic System▫ Variable displacement hydraulic pump ▫ Custom actuator package▫ Heat exchanger▫ Various filters, manifolds, accumulators, and valves
• Multi-jointed Legs• Advanced Sensors
▫ LIDAR▫ GPS and laser gyros▫ Joint sensors and stereo vision
• Computers and control software
Future Predictions•Continued advanced in quadruped
technology•Rougher steeper terrain•Even more autonomous•Faster, lighter and stronger•More range and quieter
