Explanation: None.
4. The following type of robot is most suitable for pick and place operations
a) rectangular
b) cylindrical
c) spherical
d) jointed arm type
View Answer
Explanation: The rectangular robots are often fixed-sequence robot, also called a pick-and-place robot, is programmed for a specific sequence of operations. Its movements are from point to point, and the cycle is repeated continuously.
5. A computer program that contains expertise in a particular domain is called an
a) automatic processor
b) intelligent planner
c) expert system processor
d) operations symbolizer
View Answer
Explanation: None.
6. The knowledge base of an expert system includes both facts and
a) theories
b) heuristics
c) algorithms
d) analysis
View Answer
Explanation: Heuristics is any approach to problem solving, learning, or discovery that employs a practical methodology not guaranteed to be optimal or perfect, but sufficient for the immediate goals.
7. A robot’s arm is also known as its
a) actuator
b) end effector
c) manipulator
d) servomechanism
View Answer
Explanation: The manipulator is a mechanical unit that provides motions (trajectories) similar to those of a human arm and hand.
8. Which type of actuator generates a good deal of power but tends to be messy?
a) electric
b) hydraulic
c) pneumatic
d) none of the mentioned
View Answer
Explanation: None.
9. If a robot can alter its own trajectory in response to external conditions, it is considered to be
a) intelligent
b) mobile
c) non servo
d) open loop
View Answer
Explanation: The intelligent robot, also called a sensory robot, is capable of performing some of the functions and tasks carried out by humans. It is equipped with a variety of sensors with visual (computer vision) and tactile capabilities.
10. Programming a robot by physically moving it through the trajectory you want it to follow is called
a) contact sensing control
b) continuous path control
c) pick and place control
d) robot vision control
View Answer
Explanation: None.
11. Reasoning from a goal state towards an initial state is called
a) backward chaining
b) bidirectional
c) breadth first
d) heuristic
View Answer
Explanation: Heuristics is any approach to problem solving, learning, or discovery that employs a practical methodology not guaranteed to be optimal or perfect, but sufficient for the immediate goals.
