Researchers develop robot fingers that cool off by sweating

NEW YORK: A team of researchers led by Rob Shepherd, associated professor of mechanical and aerospace engineering, created a soft robot muscle similar to fingers that can sweat to regulate its temperature. Apparently researchers at Cornell University are on board, foreign media reported.

In a press release, the researchers said it’s the basic building block for creating high-powered robots that can operate for extended periods of time without burning out.

According to Shepherd researchers trying to develop adaptable and agile robots have long been stumped on how to control the internal temperature of the robots and prevent the robot from overheating. The chances of overheating are particularly problematic for soft robots that are made by using synthetic materials. Internal cooling technology such as a fan inside the robot takes up too much space and adds weight.

Inspired by how mammals sweat, the team of Cornell researchers partnered with the lab of Emmanuel Giannelis, the Walter R. Read Professor of Engineering, the create nanopolymer materials for sweating. The researchers used a 3D printing technique that uses light to cure resin into shapes, in this case, fingers.
