The Kid Should See This

Magnetic fields make this tiny robot roll, jump, swim, and wriggle

This very small elastic strip is a robot that can walk, roll, jump, swim, and wriggle like a worm. Infused with magnetic particles, it responds to the strength and direction of magnetic fields surrounding it. As scientists modify the fields, the tiny robot can even pick things up and move them.

Could some smaller, future version of this soft-bodied robot be used for medical purposes inside the human body? See it in action in this video from Nature: A mini, magnetic, all-terrain robot.

There are more unusual robot videos in the archives, including, these Magnetically Actuated Micro-Robots, almost-invisible hydrogel robots that can grab quickly, and this mini origami robot self-folds, performs tasks, & can be dissolved.

This Webby award-winning video collection exists to help teachers, librarians, and families spark kid wonder and curiosity. TKSST features smarter, more meaningful content than what's usually served up by YouTube's algorithms, and amplifies the creators who make that content.
