mechaXY: Bluetooth-Controlled XY Precision Stage

XY Stage Mechanical

Overview

mechaXY is a Bluetooth-controlled XY precision stage built using stepper motors and an ESP32 microcontroller. Users send position commands from a custom Android app, and the stage responds by precisely actuating two axes of motion. Designed as part of ME6102 (Design of Mechatronic Systems) at IIT Bombay.

Developed by Aaron John Sabu and Radhik Rammohan in 2019.

Features

  • Wireless XY motion via Bluetooth
  • ESP32-based control firmware
  • Android app built with MIT App Inventor
  • Stepper motor drivers with directional control
  • Perfboard prototype with full schematic (Fritzing)
  • Demo videos of full-stage operation

Installation

1. Flash Firmware

Open firmware/main.ino in the Arduino IDE or PlatformIO. Select ESP32 Dev Module, and upload to your board.

2. Install Android App

  • Option 1: Import app/controller.aia into MIT App Inventor
  • Option 2: Install APK directly from app/controller_API_26.apk or app/controller_API_28.apk depending on your Android version
