The goal of this project is to build and design a robot capable of drawing a requested image by the user. The goal is to design it as compact, user-friendly and “stand alone” as possible.
The user picks an image from his phone’s gallery and, using a designated app, uploads instructions for drawing it to an NFC tag. From there, the robot can read the instruction and draw the desired image on a white board. The robot has an additional interactive screen which tells the user what fraction of the drawing is finished.
The robot’s layout is based on 5-Bar-Linkage and uses the Pico 2 microcontroller. Choosing a 5-Bar-Linkage made the robot lighter and sturdier, and the Pico 2 microcontroller is cheap and has two different cores which enabled us to move both of the robot’s arms at the same time.
