Since 2014, Clone Incorporated cofounder Łukasz Koźlik has been working on a humanoid that could be the most advanced the world has ever seen. So far, Koźlik has spent most of his time perfecting the arm, which works with artificial muscles based on a prototype from 1957. The design has made some impressive improvements over the years and can be seen lifting weights, showing off some realistic thumb motions and now wrist and forearm cooperation. | Mashable
