Heat-driven modules passed an inflation wave around a wired ring and moved a laboratory crawler 25 millimeters, while slow cycles and thermal failures bound the result.
An ETH Zurich controller learned how finger commands moved a grasped pen without simulation training or demonstrations, achieving a reported 0.64-millimeter mean in-plane error in laboratory tests.
A two-vine prototype moves a six-millimeter external channel around a sharp silicone bend, separating steering from payload space while leaving automation and performance measurement unfinished.
