Boston Dynamics BigDog

The Most Advanced Quadruped Robot on Earth

• BigDog is the alpha male of the Boston Dynamics family of robots.

It is a quadruped robot that

• walks,

• runs,

• climbs on rough terrain

• carries heavy loads.

BigDog is powered by a gasoline engine that drives a hydraulic actuation (?) system.

• BigDog's legs are articulated like an animal's, and have compliant elements that absorb shock and recycle energy from one step to the next.

BigDog is the size of a large dog or small mule, measuring

• 1 meter long,

• 0.7 meters tall

• 75 kg weight.

BigDog has an on-board computer that

• controls locomotion,
  

• servos the legs

• handles a wide variety of sensors.

BigDog's control system manages the dynamics of its

• behavior to keep it balanced,

• steer,

• navigate,

• regulate energetics as conditions vary.

Sensors for locomotion include

• joint position,

• joint force,

• ground contact,

• ground load,

• a laser gyroscope,

• a stereo vision system.

Other sensors focus on the internal state of BigDog, monitoring

• the hydraulic pressure,

• oil temperature,

• engine temperature,

• rpm,

• battery charge

and others.

So far, BigDog has

• trotted at 3.3 mph,

• climbed a 35 degree slope

• carried a 120 lb load.

BigDog is being developed by

• Boston Dynamics with help from Foster Miller,

• the Jet Propulsion Laboratory,

• the Harvard University Concord Field Station.

Development is funded by the DARPA Defense Sciences Office.
