Overview

[ARCHIVED] 4 DOF Angular Robotic Arm with GUI Controlling Software using Python/Tkinter

Important Note

This is Robo-Arm-V1 which features high level embedded code and low potency 24BYJ48-BJ stepper motors, simple GUI interface.
This repository is archived since I don't find any use mantaining the project anymore.
A Robotic-Arm-V2 will be developed soon, or not.

Features

This project features direct stepper and servomotors movement control using a simple GUI and Serial communication with a Host PC.

Project Structure

• Embedded - Embedded code using Arduino Framework

• Tkinter Code - GUI Code written in Python

• Pyserial Code - Serial Backend for microcontroller and Host PC communication

• Schematics - Electrical wiring reference

• CAD Models - 3D Models reference

Prerequisites

• Hardware:

  • Arduino UNO Dev Board (O compatible)
  • Unipolar Stepper Motors 24BYJ48-BJ
  • Driver Module ULN2003A
  • Servomotors MG90S
  • Arduino USB Cable (USB A to B)

• Software:

  • Arduino IDE
  • Python 3.13
  • Accelstepper Library

• Pip Packages:

  • Pillow
  • PySerial

How to Use

First, upload the Arduino code after following the schematics provided in Hardware/Schemes

Connect your board to the host PC and power the steppers with >24 Watts of potency. (Lesser or equal will be dangerous)

Open your terminal, search for Software/main/src/main.py and run it by entering:

python main.py

In GUI, select the COM Port you are using. You will get error message in case of selecting a closed COM Port.
