Robotics Engineering Interview Questions and Answers
Question - 1 : - What do you understand by the term, the robotics?
Answer - 1 : -
The robotics is a combined branch of engineering and science which deals with the study of development, operation, and control of intelligent robots. The robotics is a part of Artificial intelligence.
The robotics technology is used for the development of machines which can perform a complex human task in a very efficient way.
Question - 2 : - What is a robot?
Answer - 2 : -
A robot is a programmable machine which is capable of doing complex tasks automatically with precision and efficiency. The robots can be guided by external or internal input to perform any work.
A robot can be designed as resembled as human or it can be designed as a standard machine look alike.
Question - 3 : - Which was the first industrial robot?
Answer - 3 : -
The first industrial robot was "Unimate." It was manufactured by American inventor George Devol in 1950 and used in 1954. It was produced for the transportation of die casting form an assembly line and then welding on auto bodies.
Question - 4 : - What are the Laws of the robotics?
Answer - 4 : -
The "Three Laws of the robotics" also known as "Asimov's law," given by the author Isaac Asimov. The three laws are given below:
- First law: A the robot may not injure a human being or, through inaction, allow a human being to come to harm.
- Second law: A the robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
- Third law: A the robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
After that Asimov also added one more law which precedes the other laws:
Zeroth law: A the robot may not harm humanity, or, by inaction, allow humanity to come to harm.
Question - 5 : - List the name of the areas where the robotics can be applied?
Answer - 5 : -
Now a day's the robotics can be applied to most of the areas to provide efficient work with the highest precision and in less time. So there is an overview of areas where robots can be applied in day to day life as well.
- Military Area
- Industrial Area
- Agriculture Industries
- Domestic Areas
- Medical Areas
- Researches
Question - 6 : - What do you understand by "humanoid robot"?
Answer - 6 : -
A robot which looks like overall as a Human body is known as a Humanoid robot. A Humanoid robot can have human facial expressions with the features. There are two types of the Humanoid robot to resemble as male and female:
Android Humanoid: They are built to resemble a male body
Gynoids Humanoid: They are made to resemble a female body.
A humanoid robot is entirely an automatic robot which can interact with the Humans and also can react according to the surrounding.
Sophia is a first humanoid which has also got citizenship from the country of Saudi Arabia.
Question - 7 : - What are the basic aspects of the robotics?
Answer - 7 : -
The basic aspects of the robotics to create a robot are given below:
- Electrical/electronic components- The robotics required electrical and electronic components as power supply, sensors, and microcontroller and motors circuits.
- Mechanical equipment- The robotics required mechanical equipment for giving shape or designing the body of a robot
- Computer programs- The robotics also includes computer programs to provide the instructions to the robot as what type of task, when it should be done, how it should be done, etc. Robo ML, ROBOFORTH, XRCL, and visual programming are the programming languages which are used in the robotics.
Question - 8 : - What are the components of a robot?
Answer - 8 : -
There are the basic components of a robot which are given below:
- Power supply- Power supply is the main components for the run of any device or machine. So a robot also takes energy from the power supply to perform a task. It can be provided from the batteries, hydraulic, solar power or pneumatic power sources.
- Actuators- Actuators are the devices which convert energy into movement.
- Electric motors (DC/AC) - Motors are used to convert electrical energy into mechanical energy. Most of the robots used these motors to provide various type of movements to their parts. Brushless and brushed DC motors used in portable the robots and AC motors used in industrial the robots.
- Sensors- Sensors are used to sense the changes in surrounding and produce a signal. Hence the robots are also equipped with the various types of sensors to detect the environment and responded accordingly.
- Controller- Controller is the brain of a robot, which controls and co-ordinate with all parts of the robot. And with the help of the controller, the robot can perform all the assigned task. A Microprocessor is a core part of the controller, which takes various signals as Input and generate a corresponding output signal.
Question - 9 : - Why do we use robots in the industry?
Answer - 9 : -
There are the following reasons to use the robots in industry:
- The robots are used in industry as the robots can perform a task with the highest precision and efficiency.
- The robots can be operated 24/7 for continues production.
- The robots can perform some dangerous tasks in the industry.
- The robots are cost-effective concerning the industry.
Question - 10 : - What is AI? Why do we implement AI in the robots?
Answer - 10 : -
Artificial intelligence is a technology which can develop intelligent devices that can react and work as a human being. AI includes:
- Speech recognition
- Learning
- Problem-solving
- Planning
Implementation of AI in the robots makes a robot intelligent which can perform a complex task, and it can sense the environment and react accordingly.
