| 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, and climbs on rough
terrain and 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
and 75 kg weight.

| Quadruped Extension and Rotation - Thoracic Mobility |
 |
PURPOSE:
To increase mobility in the thoracic (upper)
spine.
SET UP:
Position yourself on your hands and knees
with one hand behind your head. Make sure
that the lower back is straight.
EXECUTION:
Bring the elbow of the arm behind the head
towards the opposite knee. From this
position try to "open up" as far as possible.
Concentrate on keeping the motion in the
upper back. Repeat this movement rhymically
several times.
CUES:
- Rotate the upper back
- Keep the lower back still
COMMON ERRORS:
- Reaching the elbow too far towards the
opposite knee
- Twisting the lower back

| 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, and climbs on rough
terrain and 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
and 75 kg weight.
BigDog has an on-board computer that controls
locomotion, servos the legs and handles a
wide variety of sensors. BigDog's control
system manages the dynamics of its behavior
to keep it balanced, steer, navigate, and
regulate energetics as conditions vary.
Sensors for locomotion include joint
position, joint force, ground contact, ground
load, a laser gyroscope, and 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.
In separate trials, BigDog runs at 4 mph,
climbs slopes up to 35 degrees, walks across
rubble, and carries a 340 lb load.
BigDog is being developed by Boston Dynamics
with the goal of creating robots that have
rough-terrain mobility that can take them
anywhere on Earth that people and animals can
go. The program is funded by the Defense
Advanced Research Project Agency (DARPA).
