A caterpillar with nine electric motors climbs a woodpile!
This is the first caterpillar I’ve made that can tackle variably curved terrain. 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 bounds of certain convex and concave curvatures. It is made of scrap wood and took about week to make.
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.
