1. Overview

Industrial robots are programmable mechanical devices designed to automate complex tasks in manufacturing, logistics, and service industries. Defined by ISO 10218-1 as "actuated mechanisms programmable in two or more axes," these systems combine precision mechanics, sensor technology, and advanced algorithms. Their importance stems from enabling mass customization, improving workplace safety, and optimizing production efficiency in Industry 4.0 environments.

2. Major Types and Functional Classification

3. Structure and Components

Typical robotic systems consist of:

• Mechanical structure: Aluminum/steel frames with harmonic drives
• Actuation system: Servo motors with torque transmission components
• Sensor array: Encoders, torque sensors, vision systems
• Control system: Real-time processors with ROS-based software
• End-effectors: Grippers, welding torches, suction cups
• Power supply: Integrated cabling or battery systems

Modern designs incorporate AI-driven perception systems and digital twin integration capabilities.

4. Key Technical Specifications

5. Application Fields

Major industrial applications include:

• Automotive: Spot welding robots (e.g., KUKA KR 1000)
• Electronics: Chip mounting systems (e.g., Epson SCARA)
• Logistics: AMR fleets for warehouse automation (e.g., Amazon Robotics)
• Healthcare: Surgical robots (e.g., Intuitive Surgical's da Vinci)
• Food & Beverage: Hygienic packaging robots (e.g., ABB FlexPicker)

Case Study: Tesla's Gigafactory employs over 1000 robots for battery production, achieving 99.95% process consistency.

6. Leading Manufacturers and Products
