This little bot can hitchhike, swim, and swoop with ease:
Robots on long survey missions need to conserve power whenever possible. What if they could just hitch a ride on whatever they’re studying? That’s the idea behind a new robot, inspired by remoras—fish that hitchhike onto other animals using an adhesive disk on top of their head.
Remoras use lamellae, slatlike bones encased in soft tissue, and spinules, rows of hard teethlike tissue to create tight suction. In 2017, scientists. But the disk couldn’t suction with individual lamellae, making it vulnerable to falling off. In the new study, the researchers created a disk with redundant suctions, allowing it to attach to surfaces even if part of its disk was not fully attached. Adding propellers on board enabled the robot to swim underwater and latch onto moving objects. The bot could alsoThe researchers anticipate this robot being used in a variety of situations: from diving in the water to tag animals, to long-term environmental surveys. Watch the video to see the robot tackle a variety of situations with ease.
