‘Robot blood’ powers machines for lengthy tasks

Futurizonte Editor’s Note: Robot blood? There are implications of robot blood that go far beyond science and technology. For example, religious implications.

Summary: Researchers have created a system of circulating liquid — ‘robot blood’ — within robotic structures, to store energy and power robotic applications for sophisticated, long-duration tasks.

Researchers at Cornell University have created a system of circulating liquid — “robot blood” — within robotic structures, to store energy and power robotic applications for sophisticated, long-duration tasks.

The researchers have created a synthetic vascular system capable of pumping an energy-dense hydraulic liquid that stores energy, transmits force, operates appendages and provides structure, all in an integrated design.

“In nature we see how long organisms can operate while doing sophisticated tasks. Robots can’t perform similar feats for very long,” said Rob Shepherd, associate professor of mechanical and aerospace engineering at Cornell. “Our bio-inspired approach can dramatically increase the system’s energy density while allowing soft robots to remain mobile for far longer.”

Shepherd, director of the Organic Robotics Lab, is senior author of “Electrolytic Vascular Systems for Energy Dense Robots,” which published June 19 in Nature. Doctoral student Cameron Aubin is lead author.

The researchers tested the concept by creating an aquatic soft robot inspired by a lionfish, designed by co-author James Pikul, a former postdoctoral researcher, now an assistant professor at the University of Pennsylvania. Lionfish use undulating fanlike fins to glide through coral-reef environments.
