Open Bionics makes the Hero Arm, a multi-grip bionic arm for people with upper limb differences. Open Bionics' mission is to make the most advanced bionic technology more accessible to the people that need it. The Hero Arm is the lightest bionic arm on the market, and the only one with a ventilated, adjustable socket and removable aesthetic covers. Wearers have a choice of the design aesthetic, including the official Disney Frozen, Iron Man, R2D2, and BB8 designs.
