inFORM: MIT’s Morphing Table

inFORM table

Have you ever wished your dinner table could pass the salt? Advancements at MIT may soon make this a reality — although it might spill the salt everywhere. Enter the inFORM: Dynamic Physical Affordances and Constraints through Shape and Object Actuation.

While the MIT paper doesn’t go into much detail of the hardware itself, there are a few juicy tidbits that explain how it works. There are 900 individually actuated white polystyrene pins that make up the surface, in an array of 30 x 30 pixels. An overhead projector provides visual guidance of the system. Each pin can actuate 100mm, exerting a force of up to 1.08 Newtons each. To achieve the actuation, push-pull rods are utilized to maximize the dense pin arrangement as seen, making the display independent of the size of the actuators. The actuation is achieved by motorized slide potentiometers grouped in sets of 6 using custom PCBs that are driven by ATMega2560s — this allows for an excellent method of PID feedback right off the actuators themselves. There is an excellent image of the entire system on page 8 of the paper that shows both the scale and complexity of the build. Sadly it does not look like something that could be easily built at home, but hey, we’d love for someone to prove us wrong!

Stick around after the break to see this fascinating piece of technology in action. The video has been posted by a random Russian YouTube account, and we couldn’t find the original source for it — so if you can, let us know in the comments!
