BigDog is a four-legged, 250-pound, engine-driven hydraulic quadruped from Boston Dynamics that remains one of the most nimble and maneuverable legged robots designed to-date. It’s capable of running at 4 miles per hour, climbing slopes up to 35 degrees, climbing muddy and snowy trails, and carrying up to 340 pounds over flat ground.

I joined Boston Dynamics late in this program, and as a result focused mostly on upgrades. I helped significantly improve part and system MTTF (mean time-to-failure) in the leg systems, sensors and the hydraulic powertrain, in particular.
