Robotics Engineering Interview Questions and Answers
Question - 21 : - What do you understand by numerical control?
Answer - 21 : -
Numerical control is a process of controlling the machine with the help of a computer or sets of instructions.
With the help of numerical control, we can automate the machines.
Question - 22 : - What is Servo controlled robot?
Answer - 22 : -
A servo controlled robot is one which works on the servo mechanism. Servo controlled robots are consist of servo motors which processed by the signals. A servo controlled robot can accelerate, that means these robots can change their speed at a different point.
Question - 23 : - Name of the industry which highly used the robots?
Answer - 23 : -
The Automobile industry is an industry which highly used robots for production.
Question - 24 : - What are actuators in the robotics?
Answer - 24 : -
Actuators are the electromechanical device which converts the electric energy into mechanical energy. Actuators can generate motion in each part of the robot.
Question - 25 : - What types of motors used in industrial robots?
Answer - 25 : -
There are various types of motors available, but we can choose a motor for the robotics as per the use of an area. The motor used will depend on how and where a robot is to be used. But there are some common motors which can be used in industrial robotics:
- Servo Motors
- DC/AC motors
- Stepper Motors
- Belt drive motor
- Arm adapted motors.
Question - 26 : - What is continuous-path control in the robotics?
Answer - 26 : -
When we program a robot for physically move through the trajectory or an irregular path exactly then such type of control is called as Continuous-path control in robotics.
Question - 27 : - If we wanted to add two number a and b, then how it can be written in LISP language?
Answer - 27 : -
If we wanted to add two numbers a and b, then it can be written as (+a b) in LISP language.
Question - 28 : - What is the use of the function (copy-list ) in LISP?
Answer - 28 : -
This function is used to return the copy of the defined list.
Question - 29 : - What is the Future of The robotics?
Answer - 29 : -
There are the following areas where the robotics can be used vastly in future
- The robotics can be used for e-commerce
- The robotics can be raised with cloud-based software which will define new skills in the robots
- The robotics can be used more than the industries.
- The robotics can be used in the medical field
Question - 30 : - What are industrial robots? Explain the various types of Industrial robots?
Answer - 30 : -
Industrial robots are those robots which mainly work for manufacturing and production in industries.
There are various types of robots which are being used in multiple areas depending on their work, and the following are the description of some industrial robots:
- Cartesian: Cartesian robot applies the Cartesian coordinate system(X, Y, and Z). These type of the robots have three linear joints. They also may have a wrist which can provide a rotational movement.
- Polar: The Polar robot is a type of robot which can consist of a rotatory base with an elevation pivot. The polar robot has only one arm which can perform the various task.
- SCARA: SCARA stands for "Selective Compliance Assembly Robot Arm." Sacra robot can do three linear movements with a vertical motion. It is fixed at the Z axis and flexible in XY axes.
- Delta: These robots are the shape of a spider which has parallel arms connected to the universal joints.
- Cylindrical: Cylindrical robot has a rotatory joint for the rotational transaction and a prismatic joint for performing a linear movement.
- Articulated: Articulated robots have rotatory joints which can range from simple two joints structure to a complex structure with 10 or more joints.
