Quality and Safety Considerations for Nachi Robots

Ensuring the quality and safety of industrial robots like those manufactured by Nachi is essential for protecting personnel, maintaining operational efficiency, and complying with international regulations. Nachi robots are widely used in automation, manufacturing, and precision tasks, making it imperative to follow strict safety protocols and quality assurance practices. This guide outlines the key quality and safety considerations for operating and maintaining Nachi robotic systems in industrial environments.

Safety Warning: Industrial robots operate with high speed and force. Always de-energize and lock out power sources before performing maintenance or inspections. Only trained personnel should operate or service Nachi robots to prevent injury or equipment damage.

Key Quality and Safety Measures for Nachi Robots

1. Robots Must Be Certified

   All Nachi robots must be certified to comply with relevant international safety and quality standards such as ISO 10218 (for industrial robots), IEC 61508 (functional safety), and regional requirements like CE (Europe) or UL (North America). These certifications ensure that the robots meet rigorous benchmarks for electrical safety, mechanical integrity, and environmental resilience.

   Certification also confirms that the robot has undergone extensive testing for electromagnetic compatibility (EMC), thermal management, and fail-safe operation under various load conditions. Operators should verify certification documentation before deployment.

2. Ensure Structural Integrity

   Robotic components such as arms, joints, and mounting structures are subject to continuous stress and wear. Over time, this can lead to fatigue, cracks, or loosening of fasteners—posing serious safety risks.

   Regular visual and tactile inspections should be conducted to detect signs of deformation, corrosion, or excessive vibration. Worn or damaged parts—including gears, bearings, and linkages—must be replaced immediately using genuine Nachi components to maintain performance and safety. Preventive maintenance schedules should be strictly followed based on operational hours and environmental conditions.

3. Implement Emergency Protocols

   Nachi robots must be equipped with programmable emergency stop (E-stop) functions that instantly halt all motion when activated. These systems should be integrated into the robot’s control panel and accessible from multiple locations within the workcell.

   In addition to hardware E-stops, software-based safety routines—such as torque monitoring, speed limiting, and collision detection—should be enabled. All personnel must be trained on emergency shutdown procedures, including how to safely restart the system after an interruption. Regular testing of E-stop functionality is recommended to ensure reliability.

4. Conduct Comprehensive Risk Assessments

   Before deploying a Nachi robot, a thorough risk assessment must be performed in accordance with standards like ISO 12100 and ISO/TS 15066 (for collaborative robots). This includes identifying potential hazards such as pinch points, uncontrolled movements, and electrical faults.

   Risk mitigation strategies may involve installing physical barriers, light curtains, safety scanners, or implementing speed-and-separation monitoring. The goal is to eliminate high-risk scenarios and reduce remaining risks to an acceptable level. Documentation of the risk assessment should be maintained and reviewed periodically, especially after system modifications.

5. Perform Regular Functional Checks

   Prior to each operational cycle, users should conduct functional checks of both hardware and software systems. This includes verifying motor responsiveness, joint calibration, communication between controllers, and integrity of cabling and connectors.

   Software diagnostics should confirm that firmware is up to date and that no error codes are present. Any anomalies—such as erratic movements, delayed responses, or error messages—must be investigated and resolved before resuming operations. Automated self-diagnostics can be scheduled during idle periods to enhance system reliability.

6. Maintain Sensor Accuracy

   Sensors are critical for precise operation and safety. Distance sensors (e.g., LiDAR, ultrasonic) prevent collisions, while force/torque sensors protect against excessive pressure that could damage parts or injure operators—especially in collaborative applications.

   Sensors must be regularly calibrated according to Nachi’s technical specifications. Dust, oil, or misalignment can degrade sensor performance. Cleaning and recalibration should be part of routine maintenance. For robots used in high-precision tasks, sensor validation should be performed weekly or after any physical impact.

Safety Measure	Purpose	Recommended Frequency	Tools/Methods
Certification Verification	Ensure compliance with international safety standards	Before initial deployment and after major upgrades	Certification documents, compliance checklists
Structural Inspection	Detect wear, cracks, or loose components	Monthly or every 500 operating hours	Visual inspection, torque wrench, vibration analyzer
Emergency Stop Test	Verify immediate shutdown capability	Weekly	Manual E-stop activation, response time measurement
Risk Assessment Review	Update hazard controls based on usage changes	Annually or after process change	Hazard mapping, safety audit forms
Functional Diagnostics	Ensure proper operation of all subsystems	Before each shift or daily	Control panel diagnostics, software logs
Sensor Calibration	Maintain accuracy for safe and precise operation	Every 3 months or after impact	Calibration jigs, multimeter, alignment tools

Expert Tip: Integrate Nachi robots into a centralized maintenance management system. This allows for automated reminders, tracking of service history, and early detection of recurring issues—enhancing both safety and operational uptime.

Additional Best Practices

• Provide ongoing training for operators and maintenance staff on Nachi-specific safety protocols
• Use original Nachi spare parts to ensure compatibility and maintain warranty coverage
• Keep detailed logs of all inspections, repairs, and software updates
• Install environmental monitoring (temperature, humidity) in robot workcells to prevent overheating or condensation damage
• Regularly update robot firmware to benefit from the latest safety enhancements and performance improvements

By adhering to these quality and safety guidelines, organizations can maximize the reliability, longevity, and safe operation of their Nachi robotic systems. Remember, safety is not a one-time setup but an ongoing commitment that requires vigilance, training, and proactive maintenance. When in doubt, consult Nachi’s technical support or a certified robotics integrator to ensure full compliance and optimal performance.
