Cardan system

pinshape

Hi everyone, This is a Cardan system (or shaft with universal joint) which uses a servo motor controlled by an Arduino Uno. This was a part of stair climbing robot that my group designed as a final work for the 2nd year industrial engineering. I adapted some parts so that it is totally 3D printable. The joint is very difficult to print, you need a very high resolution to make it work. You can use a cardan shaft and joint from a RC car also (like on the video). The cardan system is designed for an M6 shaft. The design can be implemented on your own robot or can be used to learn the working principle of a cardan system. It can also be a fun project for the STEM-academy because you learn mechanics, 3D printing and electronics! A small GIF of a test setup can be found here. On the Adafruit site you can learn the basic steps to control a servo motor through Arduino. Hope you like the design! Don't forget to check @Puka_ta on Instagram to stay tuned for more projects. Cheers!
