Core Types of Industrial Robots

Industrial robots come in various mechanical forms, each with unique strengths and typical applications:

Key Notes:

• Articulated robots excel in heavy industries like automotive, enabling precise welding and painting.
• SCARA robots are ideal for electronics, providing high-speed pick-and-place operations.
• Delta robots dominate in packaging, prioritizing speed.
• Cartesian systems are efficient for large parts where linear movement is necessary.
• Cobots facilitate collaboration with minimal safety barriers.
• AGVs are distinct from AMRs, which approach dynamic navigation.

Common Mistake: Don’t assume one robot type fits all tasks; consider payload, reach, speed, and environment.

Key Components & Technologies

Understanding industrial robots involves familiarization with their essential components:

• Actuators & Drives: Electric motors or hydraulic drives facilitate joint movement, impacting speed and precision.
• End-Effectors: Tools attached to the robot wrist (grippers, weld guns) ensure effective task handling.
• Sensors: Encoders, force sensors, proximity sensors, and vision cameras are crucial for safe and accurate operation (learn more about camera sensors here).
• Control Systems: Robot controllers dictate motion and safety protocols; PLCs manage cell-level functions.
• Communication Protocols: Ensure compatibility and integration efficiency.
• Software Stacks: Open-source frameworks like ROS and ROS2 facilitate complex prototyping (see our ROS2 beginner guide).
• AI/ML Technologies: Enhance robot capabilities in defect detection and adaptive control.

Tip: Use off-the-shelf components for rapid validation in initial prototypes.

Common Industrial Applications by Industry

Robots serve various sectors effectively, exemplifying their versatility:

• Automotive: Spot welding and body assembly using articulated robots for high throughput.
• Electronics: Precision tasks like PCB assembly using SCARA or delta robots.
• Food & Beverage: Automated sorting and packaging with strict hygiene standards.
• Pharmaceuticals & Medical: Cobots assist in sterile handling and lab automation.
• Logistics & Warehousing: AMRs optimize transport and sorting operations.
• Metalworking & Fabrication: Cutting and welding tasks are increasingly automated.
• Plastics & Injection Molding: Cobots manage machine tending and quality checks.

Robotics mitigate human exposure to hazardous tasks while enhancing quality and productivity.

Benefits, Limitations & ROI Considerations

Tangible Benefits:

• Increased cycle rates and throughput
• Consistent quality with fewer defects
• Reduced labor exposure to hazardous tasks
• Seamless 24/7 operation

Limitations:

• High initial costs for equipment and integration
• Programming complexity for small batches
• Skilled personnel required for operation and maintenance

ROI Calculation Steps:

1. Assess current cycle times and labor costs.
2. Estimate robot cycle periods and utilization rates.
3. Calculate annual savings to evaluate payback period using simple formulas, as shown in code snippets.

Hidden Costs: Consider integration costs, training, maintenance, and more when budgeting.

Common Mistake: Don’t underestimate integration costs; the system includes additional components vital to full operation.

Safety, Standards & Best Practices

Safety must be prioritized. Key standards include:

• ISO 10218: Safety requirements for industrial robots.
• ISO/TS 15066: Guidance for collaborative robot safety.
• OSHA Safety Resources: Provides essential safety strategies (OSHA Robotics).

Implement practical measures: physical guarding, presence-sensing technologies, and regular training for effective risk management.

Implementation Roadmap for Beginners & Small Teams

A phased approach reduces implementation risks:

1. Evaluate: Identify high-labor tasks and establish baseline metrics.
2. Pilot: Start with a single task employing cobots for ease of validation.
3. Integrate: Ensure mechanical and electrical safety and programming integration.
4. Scale: Apply lessons learned to expand operations.

Partner Selection: Consider experience level for integration tasks, which impact costs and timeline.
