Robotics Q & A

1. What is frame grabber?
It is a hardware device used to capture and store the digital image.
2. What is the common imaging device used for robot vision system?
Black and white vidicon camera, charge coupled devices, solid state camera, charge injection devices.
3. What is pixel?
Picture elements are also known as pixels
4. What is a frame of a vision data?
The digital image of the camera is called frame of vision data
5. What is segmentation?
Segmentation is the method to group areas of an image having similar characteristics or features into distinct entities representing part of the image.
6. What is thresholding?
Thresholding is a binary conversion technique in which each pixel is converted into a binary value either black or white.
7. What is region growing?
Region growing is a collection of segmentation techniques in which pixels are grouped in regions called grid elements based on attribute similarities.
8. What are the functions of machine vision system?
Sensing and digitizing image data Image Processing and analysis Application
9. What are the applications of machine vision system?
Inspection Identification Visual Servoing and navigation
10. What is a sensor?
Sensor is a transducer that is used to make a measurement of a physical variable of interest.
11. Transducer is a device which convert the one form of information into another form without changing the information content
12. What are the basic classifications of sensors?
Tactile Sensors, Proximity Sensors, Range sensors, Voice sensors etc
13. What are the desirable features of a sensor?
Good Accuracy, High Precision, Wide operating range, Instant speed of response, Good Repealibility, Low cost and ease in operation
14. What is a tactile sensor?
Tactile sensor is device which indicate the contact between themselves and some other solid objects.
15. List the different types of tactile sensor?
Digital (Touch ) Sensor and Analogue (Force) Sensor
16. .What is a touch sensor?
Sensor which senses the presence or absence of the object by having physical contact between the object
17. List the components of the force wrist
Metallic frame, Bracket for tool mounting and strain gauges.
18. What is a tactile array sensor?
Tactile array sensor is a special type of force senor composed of a matrix of force sensing elements.

Sensor which senses the presence or absence of the object without having physical contact between the object
20. What are the classifications of a proximity sensor?
Inductive Sensor Capacitive Sensor Ultrasonic Sensor Magnetic Sensor
21. What is a range sensor?
Sensor which senses the range of the object
22. What is a voice Sensor?
It is a advanced sensor system used to communicate commands or information orally to robot.
23. What is a vision Sensor?
It is a advanced sensor system used in conjunction with pattern recognition and other technique to view and interpret event occurring in the robot work space.
24. What is a potentiometer?
Potentiometer is an electrical meter to measure the voltage.
