Charles Xiao and his colleagues created a two-meter device with many segments. Just like the grapevine
The basic concept of the drive is based on the foldingpneumatic artificial muscle. The multi-segmented bot contains a pair of thin Mylar bags filled with Novec 7000 coolant. The bags are separated by insulating low-density polyethylene. Each sleeve, divided into segments, can expand when reducing the overall length. This happens when their internal coolant evaporates above 33°C.

When the heated side segment expands andshrinks, the part on the other side lengthens at the same time. The researchers emphasize that their robot can bypass simple obstacles and lean backward to remove heat. The robot also has an eversion capability, which means it can extend or turn around from the inside.
“Robots of the future based on the concepts presented could provide enhanced capabilities in search and rescue and firefighting applications,” the developers wrote.
