Researchers at Northwestern University have developed a bizarre life-like material that acts as a soft robot. This light-powered aquatic robot can walk at human speed, pick up and transport cargo to a new location, climb up hills and yes, even break dance to release a particle. It’s nearly 90% water by weight, and the dime-sized robot moves without any complex hardware, hydraulics or electricity. That’s right, it’s activated by light and walks in the direction of an external rotating magnetic field. Read more for a video and additional information.
The robot itself looks like a four-legged octopus and functions inside a water-filled tank, making it ideal for use in aquatic environments. Practical uses include using the robot to catalyze different chemical reactions and then pump out the valuable products. It could also be molecularly designed to recognize and actively remove unwanted particles in specific environments and using their mechanical movements as well as locomotion to precisely deliver bio-therapeutics or cells to specific tissues.
- With LEGO MINDSTORMS Robot Inventor (51515), kids gain essential STEM skills as they build, code and play with remote-control model robots and intelligent creations that shoot missiles, play ball, drive around and more!
- Kids build Charlie, Tricky, Blast, M.V.P. and Gelo, and take on activities and missions using the Scratch-based LEGO MINDSTORMS Robot Inventor App (visit LEGO.com/devicecheck for a list of compatible devices)
- With almost 1,000 pieces, including an intelligent Hub, 4 Medium Motors, Color Sensor and Distance Sensor with break-out interface, youngsters can also build their own fun robotic toys and share them online on LEGO Life
- An easy-to-install rechargeable battery is included, so no need to go hunting for spare batteries when the fun’s about to start
- Blast stands at over 14” (36cm) tall, while Gelo measures over 9” (24cm) long; The Powered Up components in this set are also compatible with the LEGO BOOST Creative Toolbox (17101), Droid Commander (75253) and others
Conventional robots are typically heavy machines with lots of hardware and electronics that are unable to interact safely with soft structures, including humans. We have designed soft materials with molecular intelligence to enable them to behave like robots of any size and perform useful functions in tiny spaces, underwater or underground,” said Samuel I. Stupp, who led the experimental research.
