Introduction
Definition of a Robot
“A reprogrammable, multifunctional
manipulator designed to move
materials, parts, tools, or
specialized devices, through
variable programmed motions for
the performance of a variety of
tasks”
Introduction
• History of Robotics
– 1946, memory device for controlling
machines
– First industrial robot
• 1961 at GM factory in NJ
– Invention of microchip in 1970
– Universal devices (UTD) in 1970’s
• Basically just mechanical arms
• Spot-welding, painting, loading
History (cont’d)
• 1980’s: “First Generation” robots
– Repetitive and dirty jobs
• Welding, painting, grinding
• 1990’s: “Second Generation” robots
– Able to “see” and “touch”
Theory and Background
• Overall Use
-90% industry
-10% miscellaneous (Battlebots)
• Types of Robots
-Limited Sequence
-Playback Robots
• Point-to-point
• Continuous
Advantages
• Time Efficiency
-Being able to work all three shifts
-No absenteeism
• Safety
-Reductions of accidents
• Higher Quality
-More precise
• Increased Outputs
-Higher speeds and consistent cycles
Advantages (cont’d)
• Reliability
• Reduces manufacturing lead time
• Ease of use
-Simple control panels
• Flexibility
-Capable of multiple tasks
Disadvantages
• Higher Initial Costs
-Sophisticated machinery
-Installation and machine setup
• High Maintenance
-Complex components
-Repairs
Disadvantages (cont’d)
• Takes away human jobs
• Overall Cost
– Energy Usage
– Depreciation
• Eight to Ten years service life
Applications
• Part Removal

Conclusion
• Future: “Third Generation” robots
– Intelligence and massive computing
power
– “Infer Logically”
• Work out for themselves how to do
something
Conclusion (cont’d)
• Future Capabilities
• Mobility
-”Walk” around plant
• Man-Robot Voice Communication
-Speech recognition
• Tactile Sensing
-Ability to recognize by touch
Conclusion (cont’d)
• Future Capabilities (cont’d)
– Minimize spatial intrusion
• Smaller robots
– Energy conservation
• Energy efficient robots
– General Purpose Hands
• Universal Grippers
