1. Boston Dynamic’s Quadruped Robots Ben Reed

2. 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)

3. Quadruped Robots Quadruped: four legged 5 different quadruped robots They are all similar in some respects All unique in other respects

6. 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

7. Future Predictions Continued advanced in quadruped technology Rougher steeper terrain Even more autonomous Faster, lighter and stronger More range and quieter
