Mutiple robots – machine interface – robots in manufacturing and non- manufacturing applications – robot cell design – selection of robot.

1. Unit 5
Case Studies

2. Syllabus
• Multiple robots
• Machine interface
• Robots in manufacturing and non-
manufacturing applications
• Robot cell design
• Selection of robot.

3. Robot cell design
• Robot work cell can be organised in to various
arrangements or layouts:
• These layouts are classified in to 3 basic types
– Robot centered cell
– Inline robot cell
– Mobile robot cell

4. 1. Robot centered Cell

5. 2. Inline robot cell

6. Types of Transfers
• Intermittent transfer
– Work parts will be transferred in the conveyer and all the parts stops and
starts for processing
• Continuous transfer
– Work parts will be transferred in the conveyer and will not stop for processing(
continuous movement)
– The position and orientation of the parts are not defined. (Gets Varied time to
time)
– Can be rectified by 2 means
• A Moving Baseline tracking system
– It involves the mechanism to move the robot along the path parallel to the line of travel of work
part
– Demands for addition al degrees of freedom
– Possibility of collision during multiple robots
• A Stationary baseline tracking system
– Robot will be stationary with continuous moving conveyor.
– Special tracking systems are equipped to track the orientation of the work part
– Demands for high computation power
– Complex design
• Non synchronous transfer
– Also called as power and free system
– Deals with the irregular arrival of parts

14. Applications of Robots
• Manufacturing Applications:
– Material Transfer and Machine loading and unloading
– Processing operations
• Spot welding
• Continuous arc welding
• Spray painting
• Other applications such as drilling, grinding, polishing,
riveting, waterjet cutting, laser drilling and cutting
– Assembly and inspection
• Assembly operations
• Inspection automation

15. Applications of Robots
• Non Manufacturing Applications
– Education and training
– Defense operations
– Rescue operations
– Explorations (Space, Underwater and hazardous
environments)
– Locomotion
