AMT 105 CHAPTER 4 - REVIEW QUESTIONS
The evolution of programming for robots consists of three periods called - Answer -
generations
First generation timeframe - Answer -Late 1950's through the mid 1970's
First-generation robots performed - Answer -repetitive tasks did not respond to
changing conditions only two or three degrees of freedom. used pneumatic or hydraulic
actuators for moving objects.
Programming of First-generation robots - Answer -involved adjusting mechanical stops
and limit switches.
First-generation robots often used what kind of relay logic circuits - Answer -Pneumatic
or electric relay logic circuits were commonly used.
Second-generation robots used what kind of manipulators - Answer -computer-
controlled manipulators
What did Second generation Microprocessors provided - Answer -increased processing
power at reasonable cost.
Second generation timeframe - Answer -Mid 1970's through the mid 1980's
Second generation robots were equipped with what kind of sensors - Answer -internal
sensors and closed-loop control systems.
How much feedback about the environment and condition did Second generation
sensors provide - Answer -a limited amount.
Third generation timeframe - Answer -Mid 1980's to the present.
Third-generation robots evolved through the use of - Answer -artificial intelligence.
What generation robots are capable of sensing their environment and can make
intelligent decisions about performing tasks more efficiently - Answer -Third-generation
robots
The three classifications for robotic motion control include - Answer -Pick-and-place
motion: Point-to-point motion: Continuous-path motion:
Pick-and-place motion programming is done by - Answer -manually setting mechanical
end stops or limit switches for each designated point.
