A Spanish company called Tecnalia has developed a new type of fabric that can be made to go from soft to hard and back again. Called VarStiff, the material’s default state is soft, like regular fabric; but attaching a vacuum to an embedded valve and sucking all of the air out turns the material rigid, “[achieving] hardness equivalent to that of a conventional plastic.” To get it soft again, re-introduce air.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

Wish my Spanish was a little better. Looks like a perfect material for first responders needing to stabilize something like a broken leg. Folds flat in the ambulance, form fits an individual’s limb, and can be set with a foot pump. Neat.
