Robotic Creatures

In this project we'll show you how to bring creatures to life using magnetic filament and magnets, powered by a Circuit Playground Express and Crickit, Adafruit's robotics platform! The enclosure houses the electronics and the models are printed in Magnetic PLA. Adafruit’s Crickit and Circuit Playground Express have everything you need to build a project with lights, sounds, and motor control.

These magnetic creatures come to life when placed close to the platform. Here a motor and magnet move the creatures around the platform. NeoPixel UV LED help illuminate the dual translucent material!

The print in place hinges bring these 3d printed creatures to life!

How I Designed This

Edit Design

The design is modeled in Autodesk Fusion 360 and available to edit. You can adjust the pieces to print by moving or adding construction planes to cut up the parts . You can modify the sketches or adjust features in the parametric timeline.

Design Source Files
The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the board, displays, connectors and more can be downloaded from our Fusion 360 CAD parts github repo.

Print-In-Place Critters

Print Creatures

We used Magnetic Iron Filament to print our creatures. Objects with print in place hinges that move side to side vertically, maneuver the best around the platform. You can find download links to the models we used in this project below.
