Overview
The untethered, outdoor successor to Boston Dynamics' treadmill-bound Cheetah, shown in an October 2013 video funded by DARPA's M3 program. Instead of an off-board pump, it carried a two-stroke go-kart engine coupled directly to a hydraulic pump. A small fuel tank kept weight down and gave about five minutes of running. In a parking lot it bounded and galloped at about 16 mph. DARPA's stated goal was a quadruped that could run up to 50 mph on all kinds of outdoor terrain.
WildCat was slower than Cheetah's tethered 28.3 mph but ran free, which made it the fastest untethered quadruped of its time (unconfirmed). It shared the loud gas-engine hydraulics of BigDog, which traded speed for long walks carrying loads over rough ground. Boston Dynamics' own legacy page lists WildCat at 19 mph and dates it to 2011, which differs from the 2013 coverage (unconfirmed). It suits readers of legged-robot history rather than buyers.
