    Ans.  For a library robot, suggested features:
                                 l  Sensors: Barcode/RFID readers, cameras.
                                 l  Actuators: Wheels for movement, robotic arm for picking/placing books.
                                 l  Computing: AI for catalog search and navigation.
                                       Type: A mobile service robot with manipulator.
                        2.   A manufacturing unit wants to reduce workplace accidents. Suggest how robotics could be applied in this
                            scenario, and explain which type of robots would be best suited.
                            Ans.  In a manufacturing unit, robots can perform:
                                 l  Hazardous tasks (like welding or handling toxic materials).
                                 l  Heavy lifting (reducing human strain).
                                 l  Repetitive work with high precision.
                                       Best suited robots: Industrial manipulators and autonomous mobile robots
