"Prosthesis" is operated by a human pilot that stands inside the machine. From there, the pilot is able to control the mechs movements with his arms and legs. It weighs about 3,900kg and stands at around 4.5 meters tall. According to the founder, they will build enough mechs to eventually create a new sports league based around running, jumping, climbing and lifting heavy objects. That is the first time showing up in Maker Faire Bay Area tech festival.
