Soft Robot With Microfluidic Logic Circuit

Perhaps our future overlords won’t be made up of electrical circuits after all but will instead be soft-bodied like ourselves. However, their design will have its origins in electrical analogues, as with the Octobot.

The Octobot is the brainchild a team of Harvard University researchers who recently published an article about it in Nature. Its body is modeled on the octopus and is composed of all soft body parts that were made using a combination of 3D printing, molding and soft lithography. Two sets of arms on either side of the Octobot move, taking turns under the control of a soft oscillator circuit. You can see it in action in the video below.

Microfluidic art

Microfluidics expert [J. Tanner Neville] decided to turn his work into art. Along with his student, [Austin Day], they turned lab chips into miniscule works of art by developing a technique of patterning proteins onto substrates. Each colored line you see is actually a groove full of liquid about 20 microns in width. Another student of [Neville’s], [Albert Mach], is currently working on a method of preserving the liquid for longer amounts of time. As you can probably guess, the dye tends to dry up within a few days. He is also taking submissions for artwork, so we encourage you to submit! We’re certainly looking forward to what else [Neville] and his students come up with next.
