Robotic drawing arm

thingiverse

I decide to build an robotic arm as part of my school project. It can draw with precision using control from 4 servo motors and a Wii Nunchuk. More specifications will be uploaded later, but the process becomes straightforward once you learn how to work with Arduino. To get started, you'll need 4 servo motors and a Wii Nunchuk - I used a connector, but you can skip it if you prefer. The 4 servo motors are assigned specific tasks: one for left-to-right movement, one for forward-and-backward motion, one for up-and-down movement, and the final one controls the pen or marker. I chose an Arduino Uno, which works seamlessly with the Nunchuk connector. If you don't use a connector, any other Arduino model will do as long as it has 4 connections for the servo motors and 2 for the Nunchuk. The code file is available for download, along with more detailed specifications within it - this project combines elements from various others I've worked on.
