A spin-off of the Massachusetts Institute of Technology (MIT), Boston Dynamics, develops robots that magnify or improve human and animal capabilities to perform awe-inspiring tasks. These robots move with the strength and agility of animals. They can also change shape to navigate in tight spaces or climb walls.

We would like to focus upon one of these creations, BigDog. The robot is a four-legged, three feet tall, three feet long, 109kg dog-like robot that can manoeuvre up a muddy slope and carry a 154kg load.

Go-kart engine

A 11kW go-kart engine, comprised of a two-stroke/one cylinder, water-cooled operation, powers a hydraulic system that operates the legs. The leg design was fashioned by designers after large mammal's natural movements.

Sensors

Fifty sensors feed into a computer to help maintain balance and direction as well as helping the robot recover in the event of a fall or being forced off its intended course.
