Drive a [CNC-shield, Steppers, Arduino] based Robot Arm with Hand Gestures using Leap Motion Controller

Robot arm controller

I made this code to control a 3D printed robot arm I built using:

• Arduino
• Nema 17 - stepper motors
• CNC-Shield
• A4988 stepper motor driver
• Leap Motion Controller v1 (first version)

Libraries

• leapjs
• serialport

Preview

I made a brief YouTube video to show the project:

How to use

• Install the Leap Motion software (use v2.3.1 you find under "Legacy Downloads" on the Leap Motion offcial website)
• Open the software and check the "Allow Web Apps" checkbox to turn on the WebSocket server that provides tracking data to web applications
• Use leapjs to connect to Leap Motion with JavaScript
• Setup your Arduino with GRBL
• Connect to Arduino using Serial Communication (serialport.js library)
• Now you can send GCODE to Arduino based on the data you receive from the Leap Motion

⚠ IF YOU ARE USING WINDOWS 10:

There is a bug in the Leap Motion software on Windows 10, here is how I fixed it:
