Like a 3D printed swimming crash test dummy, the SWUMANOID (SWimming hUMANOID robot) is for the research of unsteady fluid force.
To clarify the unsteady characteristics of the fluid force acting on a swimmer, an underwater swimming humanoid robot was developed. The swimming robot was actuated by 20 motors and could perform the various human swimming motions with four limbs.
The researchers 3d scanned a human then 3D printed the form at half scale. I do wonder how they adjusted the buoyancy of super light nylon (we assume) to that of human flesh?
