Jawaharlal Nehru Technological University Hyderabad B.Tech IV Year INDUSTRIAL ROBOTICS Previous Question Paper (September - 2022 - R18)

• Versatility and Flexibility: Industrial robots are programmable, allowing them to be repurposed for different tasks by changing the end-effector or software, which is essential for high-mix, low-volume production.
• Consistency and Precision: Robots perform repetitive tasks with high repeatability and accuracy, ensuring uniform product quality and reducing the defect rate compared to manual labor.
• Operational Efficiency: Robots can operate continuously for long durations without fatigue, breaks, or shift changes, significantly increasing the throughput of a manufacturing line.
• Safety in Hazardous Environments: They are ideal for dangerous tasks such as welding, painting, handling toxic materials, or working in extreme temperatures, thereby removing human operators from hazardous conditions.
• Scalability: Robotic systems allow for easy integration into existing production lines and can be scaled up as production demands increase.
• Data Collection and Monitoring: Modern robots are equipped with sensors that provide real-time data on performance, enabling predictive maintenance and process optimization.

Automation is the technology by which a process or procedure is accomplished with minimal human assistance. It involves the integration of mechanical, electrical, and computer-based systems to operate and control production processes.

The transition from mechanized units to automated systems is driven by several critical factors:

• Increasing Labor Costs: Automation reduces dependency on human labor, which is often the most significant variable cost in manufacturing, especially in high-wage regions.
• Improving Product Quality: While mechanized units provide mechanical advantage, they lack the closed-loop control of automated systems. Automation ensures tighter tolerances and consistent quality control.
• Shortage of Skilled Labor: As manufacturing processes become more complex, finding skilled workers for repetitive, manual tasks becomes difficult; automation bridges this gap.
• Increasing Productivity: Automated systems operate at higher speeds and with fewer interruptions, maximizing the utilization of capital equipment.
• Safety and Ergonomics: Automating tasks that involve heavy lifting, repetitive motion, or ergonomic strain protects the workforce from musculoskeletal disorders and workplace injuries.
• Global Competition: To remain competitive in the global market, industries must adopt automation to lower unit costs and improve the speed-to-market of their products.
