Overview

ArUco markers auto-align tool, conveyor, and vision system, correcting misalignment in real time with no teaching.

Project Background & Purpose

This demonstrates automatic alignment of a tool, conveyor, and vision system using a Universal Robots arm and ArUco markers — the robot and computer vision detect and correct misalignment in real time. Processes requiring precise coordinate agreement between tool, conveyor, and vision system suffered repeated misalignment and downtime when relying on manual teaching.

Components

• Universal Robots cobot
• ArUco markers
• Vision system

Process Steps

1. 1Attach ArUco markers at the tool, conveyor, and vision system reference points
2. 2The robot recognizes the markers and checks for misalignment against reference coordinates
3. 3On detecting misalignment, the system re-aligns the position in real time
