This 10-pound, two-legged robotic replica of a Troodon from the Cretaceous period walks like the real thing
To the high-pitched hissing sound of electric servos, Troody slowly tilts forward. Fourteen tiny motors in her limbs begin to hum as her shins lift up from her feet. She stretches her legs and rises to an upright position. Still wobbling back and forth a bit, she takes her first timid step forward, then another—and then she is walking.
