The TurtlePlotBot is a MicroPython based 3D printed drawing robot inspired by MakersBox's Arduino Chassis for Drawing Robot. The TurtlePlotBot can be easily built in a couple of hours and offers a fun environment to learn python programming and robotics.
The software that runs the TurtlePlotBot is modular and includes the turtleplot module. The turtleplot module contains the methods needed to turn turtle graphics commands into simple robot movements. You can use the turtleplot module run your own robot using different hardware without having to write all the python code for each of the turtle graphics commands.
A TurtlePlotBot is built from 3D printed parts, a pair of 28BYJ-48 stepper motors and uses a MG90S mini servo to lift and lower a pen used for drawing.
An ESP-32 Based Microcontroller module with a 240x135 LCD display running MicroPython is paired with a ESP32 DrawBot Board to provide the interface circuitry needed to run the stepper motors, servo, MicroSD card and a five way joystick. The TurtlePlotBot has Wifi capability allowing it to be controlled and programmed wirelessly from a computer, smartphone or tablet.
A menu system provides an easy way to configure the TurtlePlotBot, connect to or create a Wifi access point as well as running TurtlePlotBot MicroPython programs without the use of a computer or another device.
