Figure 1. Nice model of a Flexbot leg. The green parts are the main joints, foot, knee and hip. The black tubes are 16mm carbon fibre tubes, at the ends there are black plastic blocks, that connects the tube to the joint axle. The aluminium colourized parts are actuators and the base frame of the robot. The layout of the main joints are slightly outdated.
