A Robotics Assembly and Maintenance Worker (often covered by Electro-mechanical and Mechatronics Technologists and Technicians) installs, programs, troubleshoots, and performs preventive maintenance on robotic systems and automated machinery used in manufacturing and industrial settings. They bridge the gap between mechanical, electrical, and computer systems to keep complex automation running smoothly.
Typical Education
An Associate's degree in electro-mechanical technology, mechatronics, or robotics is the typical entry-level education for this specialized technical role.
Salary Range in the United States
The median annual wage for Electro-mechanical and Mechatronics Technologists and Technicians was $70,760 in May 2024. The lowest 10 percent earned less than $47,770, and the highest 10 percent earned more than $109,580.

How to Become a Robotics Assembly and Maintenance Worker
- Complete a Technical Degree: Earn an Associate's degree in Mechatronics, Robotics, or a related industrial automation technology program from a technical college.
- Master PLC and Programming: Gain high proficiency in programming, troubleshooting, and integrating Programmable Logic Controllers (PLCs), which control most industrial robotics.
- Obtain Vendor-Specific Training: Complete specialized training and certification offered by major robot manufacturers (e.g., FANUC, ABB, KUKA) on their specific robot hardware and programming language.
- Seek an Apprenticeship or Internship: Secure a position with a robot integrator or a manufacturing facility to gain hands-on experience applying classroom knowledge to live production systems.
- Develop Multi-Disciplinary Skills: Focus on developing expertise in the three core areas: mechanical systems (kinematics), electrical systems (wiring, sensors), and programming (logic, control).
Essential Skills
- PLC Programming and Logic: Expert skill in reading, writing, and debugging ladder logic or other languages used by PLCs to sequence and control robot movements and peripherals.
- Electrical and Mechanical Troubleshooting: The ability to use voltmeters, oscilloscopes, and hand tools to diagnose failures across mechanical, electrical, pneumatic, and hydraulic components within the robotic cell.
- Robot Programming: Proficiency in setting up robot paths, establishing waypoints, teaching positions, and modifying programs to integrate new tasks or optimize existing cycles.
- System Integration: The capacity to integrate robots with external devices, such as vision systems, conveyors, safety light curtains, and end-of-arm tooling.
- Safety System Expertise: Thorough knowledge of industrial safety standards (e.g., OSHA, ISO) related to robotic work cells, including setting up and verifying interlocks, fencing, and safety zones.
Key Responsibilities
- Perform Preventive Maintenance (PM): Conduct scheduled inspections, lubrication, cable checks, battery replacements, and calibrations on robotic arms and controllers to maximize uptime.
- Diagnose and Repair Failures: Quickly troubleshoot and repair both hardware (motors, sensors, cables) and software (programming errors, communication issues) failures to minimize production line downtime.
- Assemble and Install New Cells: Assist in the physical assembly, wiring, and initial setup of new robotic work cells, ensuring all components and safety devices are correctly integrated.
- Program and Test Applications: Develop and modify robot programs for new tasks (e.g., welding, picking, placing), and perform rigorous testing to ensure accuracy, speed, and quality.
- Maintain Documentation: Keep detailed records of all maintenance actions, repairs, program versions, and system modifications for compliance and future reference.
Five Common Interview Questions
- "A robot suddenly stops and displays a 'Safety Fence Open' error, but the fence looks closed. What is your diagnostic process to find the actual fault?" This assesses your troubleshooting skills related to safety circuits and sensor logic, a critical area in robotics.
- "Describe your experience with PLC programming languages (e.g., Ladder Logic, Structured Text). Can you give an example of a function block you created?" This tests your automation control expertise and ability to interface robots with the main production control system.
- "Walk me through the proper 'lockout/tagout' procedure for a complex robotic work cell that has multiple power sources (electrical, pneumatic)." This checks your safety compliance and ability to perform authorized energy control procedures.
- "What is the difference between an absolute encoder and an incremental encoder on a robot joint, and why is this important for maintenance?" This measures your fundamental technical knowledge of robot components and their role in positional accuracy.
- "Tell me about a time you needed to teach a new path to a robot arm. How did you ensure the new path was both efficient and free of collisions?" This tests your robot programming skills and your spatial awareness in defining safe operational zones.
