SNU Soft Robotics Center led by Professor CHO Kyu-Jin has developed a foldable robotic arm like ‘Inspector Gadget’ arm.

Adding a robotic manipulator to unmanned aerial vehicles is a big challenge because increasing weight and size can be critical to those vehicles

Inspired by the origami, the researchers have designed a flat, foldable, light-weighted, but highly stiff robotic arm that can be attached to UAVs.

A single module of 28 g can withstand over 12 kg, which is more than 400 times of its own weight.

The origami-inspired design makes it possible to create light-weighted, highly rigid, and self-assembling structures. It might be possible in the future to create building structures for extreme environment with this origami-inspired design.
