JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech III ROBOTICS Previous Question Paper (February/March - 2022 - R16)

The integration of CAD/CAM and robotics creates a synergistic environment known as Computer Integrated Manufacturing (CIM). The combined effects include:

• Seamless Data Flow: CAD designs are directly converted into machine-readable code (CAM), which is then executed by robotic systems, eliminating manual data entry errors and reducing lead times.
• Enhanced Precision and Consistency: Robotics ensure that the complex geometries designed in CAD are manufactured with high repeatability, maintaining tight tolerances that are difficult to achieve manually.
• Increased Flexibility: CAD/CAM systems allow for rapid prototyping and quick reconfiguration of robotic workcells, enabling manufacturers to switch between product lines with minimal downtime.
• Optimization of Resources: Simulation tools within CAD/CAM environments allow for the virtual testing of robotic paths and cycle times before physical implementation, leading to optimized material usage and reduced energy consumption.
• Improved Quality Control: Automated inspection routines can be integrated into the robotic workflow, where CAD data serves as the reference model for real-time quality verification.

Robot systems have evolved from simple repetitive tasks to complex, autonomous operations. Their applications are categorized as follows:

Present Applications:

• Manufacturing: Dominant in automotive and electronics industries for spot welding, arc welding, spray painting, and high-speed pick-and-place assembly.
• Material Handling: Palletizing, machine loading/unloading, and automated guided vehicles (AGVs) for warehouse logistics.
• Healthcare: Surgical robots assisting in minimally invasive procedures and rehabilitation robotics for physical therapy.
• Hazardous Environments: Handling radioactive materials, bomb disposal, and deep-sea or space exploration tasks.

Future Applications:

• Service and Domestic Robotics: Advanced human-robot interaction for elderly care, personal assistance, and autonomous home maintenance.
• Precision Agriculture: Autonomous drones and ground robots for crop monitoring, selective harvesting, and automated pesticide application.
• Collaborative Construction: Robots capable of 3D printing large-scale infrastructure or performing dangerous tasks on high-rise construction sites.
• Advanced Logistics: Fully autonomous last-mile delivery systems and intelligent swarm robotics for complex supply chain management.
