• Artificial Intelligence: Robots can be equipped with AI algorithms to learn, adapt, and make decisions.
• Collaborative Operation: Robots can work safely alongside human operators, enhancing flexibility and productivity.
• Remote Monitoring: Robots can be remotely monitored and controlled, facilitating maintenance and support.

Story 1: The Over-Ambitious Factory

A factory installed an articulated industrial robot to automate the painting process. However, they chose a robot with a reach too short to paint the entire area. The result? An unfinished paint job and a wasted investment.

Lesson: Define clear requirements and select a robot that matches those needs.

Story 2: The Uncooperative Robot

A manufacturing facility purchased a high-speed robot to increase productivity. Unfortunately, they neglected to train their operators properly. The operators made programming errors, leading to frequent collisions and downtime.

Lesson: Train operators thoroughly before implementing robots to ensure safe and efficient operation.

Story 3: The Robot Revolution

A company embraced automation by replacing all manual laborers with articulated industrial robots. While productivity initially soared, the lack of human interaction led to a decline in innovation and creativity.

Lesson: Implement robots as a complement to human workers, not as a complete replacement.

Potential Drawbacks of Articulated Industrial Robots

• High Initial Cost: Purchasing and installing robots can be expensive.
• Complexity: Robots require skilled technicians for maintenance and repair.
• Job Displacement: Automation can potentially lead to job losses for human workers.
• Safety Concerns: Robots must be properly guarded and operated to prevent accidents.
• Limited Flexibility: Robots are designed for specific tasks and may not adapt easily to changing production requirements.
