BigDog Robot Learns To Obey Voice Commands, Follow, Roll Over

DARPA's menacing military machine gains some new tricks.

The Legged Squad Support System, a.k.a. BigDog, which looks more like the offspring of a bull and a spider than a dog, shows off some new skills in this video. At the order “Follow tight,” the stocky robot keeps pace behind its master, trekking uphill through autumnal woods with an ominous whine of servos.

It also demonstrates an impressive ability to stand back up and continue marching after suffering a nasty roll into a puddle.
