Applications in medicine, homeland security, search and rescue. The first single actuator wave-like robot (SAW) has been developed by engineers at Ben-Gurion University of the Negev (BGU). The 3D-printed robot can move forward or backward in a wave-like motion, moving much like a worm would in a perpendicular wave.
SAW can climb over obstacles or crawl through unstable terrain like sand, grass and gravel, reaching a top speed of 22.5 inches/s, 5X faster than similar robots. Its minimalistic mechanical design produces an advancing sine wave with a large amplitude, using only a single motor with no internal straight spine...
