3d Robot Hand Gesture Control using Computer Vision

Murtaza's Workshop - Robotics and AI3 October 2026Watch on YouTube

What you'll learn

  • You learn how a webcam tracks the user's hand using computer vision.
  • You see how Python calculates the bend angle of every finger joint.
  • You learn how a 3D robot hand in the browser copies your movements in real time.
  • You follow the vision side, the math and the communication between Python and the browser step by step.
  • The same angles can later drive a real servo-powered robot hand.

Frequently asked questions

What do you build in this tutorial?
You build a gesture-controlled robot hand from scratch. A webcam tracks your hand, Python calculates the bend angles and a 3D robot hand in the browser copies your movements in real time.
What exactly does Python calculate in this setup?
Python calculates the bend angle of every finger joint based on the hand tracked by the webcam.
Where do you see the 3D robot hand move?
The 3D robot hand runs in the browser and copies your hand movements in real time.
What can you do later with the calculated angles?
The same angles are meant to later drive a real servo-powered robot hand, which is covered in a separate video.

Description from the channel

Download Files: https://computervision.zone/cv-academy/robotics In this tutorial, we build a gesture-controlled robot hand from scratch. Your webcam tracks your hand, Python calculates the bend angle of every finger joint, and a 3D robot hand in the browser copies your movements in real time. This is a coding tutorial, not just a demo. We go step by step through the vision side, the math, and the communication between Python and the browser, so you can use the same approach in your own projects. The same angles will later drive a real servo-powered robot hand, which is coming in a separate video.
