A robotic arm designed for an assembly line would be created by

• A. A single engineer
• B. A group of technicians from the shop floor
• C. A team composed of engineers from several areas of engineering
• D. The purchasing department

Answer: (C)

Designing a robotic arm for an assembly line requires input from multiple engineering disciplines to address all aspects of the system. Mechanical engineers shape the arm’s structure, joints, actuators, and payload capacity; electrical or electronics engineers handle sensors, motor controllers, wiring, and power management; software or control engineers develop the real-time control algorithms and ensure the system integrates with factory PLCs and control software. Systems engineering and manufacturing engineers help with integration into the production line, manufacturability, reliability, and maintainability, while safety engineers ensure compliance with relevant standards. Because such a project spans mechanical, electrical, software, and safety domains, a team composed of engineers from several areas of engineering is the most effective way to design, test, and implement the robotic arm. A single engineer lacks the breadth to cover all these aspects, and technicians from the shop floor or the purchasing department don’t provide the full design expertise needed for development.
