Boston Dynamic’s Quadruped Robots Ben 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’t RobotCapacityRangeWeightPrimary Use BigDog340 lbs6.2 miles240 lbsCarry Equipment LittleDogN/A 30 minutes continuous operation N/AStudy movement LS3400 lbs20 miles850 lbs Carry equipment (Marine Corps) WildCatunknown Study movement, Increase speed of robotic movement

Technological Advances Rough terrain capable ▫BigDog (video)video ▫LS3 Advanced autonomy ▫BigDog ▫LS3 (video)video ▫WildCat Record holding speed ▫Cheetah (video)video ▫WildCat (video)video Advanced study of locomotion and movement ▫LittleDog (video)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
