DARwIn - OP: (Dynamic Anthropomorphic Robot with Intelligence - Open Platform) is an affordable, miniature-humanoid-robot platform with advanced computational power, sophisticated sensors, high payload capacity, and dynamic motion ability to enable many exciting research, education, and outreach activities. Darwin runs on UbuntuLinux (adaptable to other systems).
Imagine the NASA hacking applications. Remove the legs and put this robot's upper body on a small ROV. Make the arms longer, add better (and exchangeable) end effectors, and put better optics in its head. Video below.
