Engineers at The University of Tokyo have developed a flexible robotic manipulator inspired by the neck of an ostrich, which they call RobOstrich.
The researchers used anatomical data to create seventeen 3D printed vertebrae that were linked together with bearings, and bundles of springy piano wire and rubber bands to serve as muscles and ligaments respectively. The RobOstrich can perform complex functions, such as reaching for an object, with simple actuation patterns.
Through testing, the team found that the robot can move in patterns with the same characteristics as the neck movements of an ostrich. However, at present, the robot can only move in two dimensions, although the team is now working to achieve three-dimensional movement for a future version of the manipulator.
If successful, this platform could serve as the basis for a new generation of flexible robotic manipulators (or robotic ostriches!) that can perform tasks that were once too challenging to achieve with any practical device.
The study showcases the potential of biomimicry in robotics, as scientists and engineers increasingly turn to nature to inspire better, faster, and more efficient machines.
