Basic Concepts | Robotic and Automation | Questions Answer For Interview
In this post we will see important questions regarding Robotics and automation – Basic Concepts . This questions with answers are helpful for interview ,viva , oral examination regarding robotics and automation subject or field.
1. Define a Robot?
RIA defines a robot as a “programmable, multifunction manipulator designed to Move materials, parts, tools or special devices through variable programmed motions for the performance of the variety of task”.
2. What is mean by automation?
Automation is a technology that is concerned with the use of electronic mechanical and computer based system in the operation control and production.

3. What is a robot?
Robot is an
• Electro-mechanical device
• Perform various task
• May be human controlled or automated.
• It finds its uses in all aspects of our life
4. What are the rules of robot?
• Do not harm being
• Obey human being
• Protects itself from harm.
5. Why a robot used?
a. To reduce production cost
• Difficulties in human nature
b. To avoid 3-D jobs
6. What is meant by robot anatomy?
Robot anatomy means study of structure of robot. Manipulator is constructed of a series of joints & links. A joint provides relative motion between the input link and the output link. Each joint provides the robot with one degree of freedom.
7. Name the commonly used robot configuration system?
The commonly used robot configuration systems are
- Cartesian coordinate system
- Polar or spherical coordinate system
- Revolute coordinate system
- Cartesian coordinate system
8. What are the types of automation?
• Fixed automation
• Programmable automation
• Flexible automation
9. Write are the Benefits of industrial automation?
• Improved product quality
• Improved safety
• Increased manufacturing flexibility
• Improved operation reliability
• Improved decision making
10. List the different types of robots?
• Robotic Manipulator
• Wheeled Mobile Robots
• Legged Robots
• Underwater Robots
• Flying Robots
• Robot Vision
• Artificial Intelligence
• Industrial Automation

11. Write Asimov’s laws of robotics?
Three rules written by science fiction author Isaac Asimov and later expanded upon. These rules are built in to almost all positronic robots appearing in his fiction and cannot be bypassed. The rules are introduced in his 1942 short story Runaround although they were foreshadowed in a few earlier stories.
The Three Laws of Robotics are as follows:
I. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
II. A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law.
III. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
12. What is mean by workspace?
The space in which the end point of the robot arm is capable of operating is called as a workspace in other words reachabillity of robot arm is known as workspace.
13. What are the limitations of robot?
Assembly dexterity does not match that of human beings, particularly where eye- hand coordination required.
• Payload to robot weight ratio is poor, often less than 5%
• Robot structural configurations often constrain joint limits and thus the work volume
• Work volume can be constrained even further when parts of substantial size are picked up when tooling/sensors added to the robot
• The robot repeatability and/or accuracy can constrain the range of potential application
14. What is meant by work envelop?
The work envelop is described by the surface of the workspace.
15. What is meant by a accuracy of robot?
The robot’s ability to reach a reference point within the robot’s full work volume is known as accuracy of robot.
16. What is meant by pay load capacity of robot?
The maximum load which can be carried by the manipulator at low or normal speed
17. What is meant by precision of robot?
It is the smallest increment of motion for which the robot can be controlled
18. What is repeatability of robot?
Repeatability refers to robot’s ability to return to the programmed point when it is commanded to do so.
19. What is meant by quality of robot?
A robot is said to be high quality when the precision and accuracy is more
20. Classify the motion control of Robot arm?
• Limited sequence control
• Point to point control
• Continuous path control
• Intelligent control
21. What are the Subsystems of industrial robot?
• Transmission systems
• Power supplies & power storage system
• Microprocessors & controllers
• Algorithms & softwares (higher level & lower level)
22. What is meant Degrees Of Freedom?
It is described as one of the variables required to define the motion of a body in space. Each joint in a robotic system gives the robot one degree of freedom.
