The NexBot Robotics 921-004 Preventive Maintenance Plan is a comprehensive annual service designed to ensure your robotic systems operate at peak performance, safety, and reliability. This FAQ outlines what is included in the plan, the process, and its benefits.
Answer: Service Scope and Inclusions
The NXB-KIT-921-004 Preventive Maintenance Plan is an on-site service performed by a NexBot Robotics certified Field Service Technician. The primary goal is to proactively identify and address potential issues before they result in unplanned downtime. The service is structured around a detailed 40-point inspection checklist, which covers all major aspects of the robot system.
This plan is applicable to the following NexBot Robotics series:
- R-20 (Articulated)
- R-50 (Articulated)
- C-10 (Collaborative)
- S-5 (SCARA)
Key Areas of the 40-Point Inspection
While the full checklist is proprietary, the inspection covers these critical domains:
1. Mechanical Systems Inspection:
- Axis Drives & Gear Reducers: Inspection for abnormal noise, vibration, and excessive backlash. Lubricant levels are checked, and samples may be taken for analysis if specified.
- Belts & Pulleys: Belts are inspected for proper tension, frays, and signs of wear. Pulley alignment is verified.
- Robot Structure & Castings: Visual inspection for stress fractures, impact damage, or loose hardware.
- End-of-Arm Tooling (EOAT) Interface: Mounting flange and connectors are inspected for wear and secure connections.
- Hardware & Fasteners: Critical mounting bolts are checked to ensure they meet factory torque specifications.
2. Electrical & Control Systems Inspection:
- Controller Cabinet: Internal components are inspected for dust or debris buildup. Cooling fans are cleaned and tested for proper operation.
- Cabling & Connectors: Robot and controller cables are inspected for chafing, cuts, or loose connections. Connector pins are checked for damage or corrosion.
- Power Supplies: Voltages are measured to ensure they are within specification.
- Safety Circuits: All safety systems, including Emergency Stop buttons, safety gates, and light curtains, are functionally tested to ensure they perform as designed.
3. Software & System Diagnostics:
- System Backup: A complete backup of the robot's software, programs, and system parameters is performed.
- Error Log Review: The system's error history is analyzed to identify recurring or unresolved faults that may indicate an underlying issue.
- Firmware Check: The technician verifies the installed firmware versions and advises if critical updates are available.
4. Performance & Calibration Verification:
- Robot Mastering/Calibration: The robot's mastering values are checked for drift. A basic repeatability test is performed to confirm the robot can accurately return to taught points.
- Program Execution: A standard production program is observed to verify smooth motion and normal operation.
What is typically NOT included?
- Cost of replacement parts not covered by warranty.
- Emergency or breakdown service (this is a scheduled, preventive service).
- Major repairs, retrofits, or application reprogramming.
- Consumables like grease, oil, or batteries unless specified as part of a package add-on.
Tips for a Successful Maintenance Visit
To ensure the technician can perform the service efficiently, please prepare the following:
- Provide Clear Access: Ensure the robot cell and controller cabinet are easily and safely accessible.
- Schedule Appropriately: Schedule the service during a period of planned downtime to avoid interrupting production.
- Gather Information: Have any recent error logs, operator observations of unusual behavior, or maintenance records available for the technician to review.
- Authorize Personnel: Ensure a qualified plant representative is available to authorize any recommended follow-up actions or repairs discovered during the inspection.

The NXB-KIT-921-004 plan is a cornerstone of a robust asset management strategy. To further enhance your team's capabilities, consider the following:
- Operator & Maintenance Training: Enrolling staff in certified training, such as the NXB-TRN-913-004 course, empowers them to perform daily checks and identify early warning signs of system degradation.
- Corrective Maintenance: While this plan is preventive, any issues found may require corrective action. Having a stock of common wear items, such as those found in basic maintenance kits like NXB-KIT-912-004, can expedite repairs.
