Lego-compatible prosthetic arm lets children swap grips

The standard three-finger grip can be replaced by one made entirely of Lego.

Umeå University designer Carlos Arturo Torres has designed a prosthetic arm called the Iko that children can equip with their custom claws.

Iko was developed during an internship at the Lego Future Lab, and is intended to aid children with prosthetic limbs. In terms of function, Iko acts like a traditional prosthetic arm, but with a Lego-compatible twist-and-lock design that makes assembly simple for children. Its three-finger claw can be swapped out for one made entirely of Lego and custom-designed by the user.

A charging station connects to the upper arm of the missing limb, and contains a processor and sensors that detect muscle movement.

Iko was designed to help children get over the stigma of wearing a prosthetic by making them fun. During his stint at the Lego lab, Torres found that Lego lets children improve social connections and encourage them to boost their creativity.
