An amazing 3D printed project from gifted designer Matthew Borgatti uses pneumatically controlled air chambers to create the spooky, organic behaviors of this design, detailed further in Soft Robots. And check out his posts in the Adafruit Forum as he developed the project! From the video description:
I’ve been developing ways to use 3d powder printing to make air powered robots that have no hard moving parts. Using procedural modeling I can create rapid iterations, incremental designs, and inexpensive prototypes with a simple set of tools. Find more details here.
Here’s an early demonstration of a trefoil tentacle in action. There are three hollow ribbed volumes inside this tentacle that control its motion. It is controlled through a Processing interface and an Arduino switching a bank of solenoid valves using a simple Darlington transistor. You can grab the code here at the Adafruit Forums.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
