A Climbing Robot Caterpillar

Kinetic artists Reuben Margolin has made a number of robots that are like sculptures, or sculptures that are like robots. We like anything that proves engineering and art can be the same thing. Here’s more from Reuben Margolin:

Inside the caterpillar is a micro-controller holding a file with a quarter million angles. As the motors sequentially follow these angles, the caterpillar traverses the woodpile.

The woodpile is not as random as it looks, but follows a predetermined polynomial spline within certain bounds of curvature. It is made of scrap wood and took about week to make. The caterpillar took several months, although a lot of that time was spent learning about servo motors, micro-controllers, Terminal and Python, and learning how to use an oscilloscope to trouble shoot the square wave signal that carries the angular information.

Screenshot 4 2 14 11 48 AMEvery Tuesday is Art Tuesday here at Adafruit! Today we celebrate artists and makers from around the world who are designing innovative and creative works using technology, science, electronics and more. You can start your own career as an artist today with Adafruit’s conductive paints, art-related electronics kits, LEDs, wearables, 3D printers and more! Make your most imaginative designs come to life with our helpful tutorials from the Adafruit Learning System. And don’t forget to check in every Art Tuesday for more artistic inspiration here on the Adafruit Blog!


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.
