Check out Spidey, an open source legged robot (and robot platform) designed in OpenSCAD with printed parts that can be completed in about 12hrs of print time, and additional dedicated electronics and hardware that you can purchase from Robotis and other sources. Via 3ders.org.
This is intended to be a standard platform for hobbyists, research and education. You can easily change any part of its 3D design, like setting new dimensions, number of legs or adding new parts, but also its electronics, adding new sensors or actuators, and, of course, its software, creating new behaviours, gaits or any intelligence you can think of!
Making the robot yourself is quite easy, it requires to order some parts, mainly from Robotis.
The original Spidey contains 12 XL-320 actuators, which is the main component of the price. You’ll also have to buy its controller, the OpenCM9.04 (type B), and a battery. You’ll also have to print some 3D parts. On our printers, we can build a Spidey in about 12 hours of print time….
…The parts were designed using OpenSCAD, a free and open-source tool. The source code of the parts is flexible and parametric, you can change the number of legs, the size of the robot etc.
You can customize your robot really quickly, by editing the scad files, re-generate the parts and then 3D-print it! …
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
