Robita, a Japanese hobbyist and blogger, is currently in the process of re-engineering his Ignis bipedal humanoid robot. He uses CAD to design all the metal brackets and uses primarily Vstone’s powerful VS-S281J (torque: 28.5 kg/cm). In the following video, you can see one of his robot’s legs supporting a 1.5 L bottle of water without breaking a sweat. You can also check out what the previous version of the completed robot looked like here.
