Alex

IHMC full-body humanoid

IHMC's all-electric successor to its hydraulic Nadia, funded by the US Office of Naval Research, with legs jointed like a human's, human-like arms and a faceless head, built to work outdoors in disaster and military settings. It is expected to weigh about 85 kg with battery versus about 100 kg for Nadia; reported DoF counts conflict (19 vs 29). Not to be confused with Boardwalk Robotics' upper-body Alex.
