Q

Selectivity

A

Capacity of a sensor to measure a single parameter without being affected by the presence of others

18
Q

Response time

A

It is the time it take for a transducer to reach a stable output when it is exposed to a given input (also named as Rise time or settling time)

19
Q

Vision sensors

A

Cameras, laser, ultrasonic, radar, lidars, stereo, kinect

20
Q

Touch and hearing

A

Micro switches, limit switches, pressure, capacitive

Microphone

21
Q

Kinesthetic and proprioception

A

Rotation and gps

22
Q

Industrial proximity sensor

A

Limit switch, ultrasound, Inductive, Capacitive, photoelectric

23
Q

Parts of a sensor

A

Sensitive element ( part that feels) and transducer (affected by the change of the sensitive element)

24
Q

Passive sensor

A

The ones that don’t require any external source

25
Q

Active sensors

A

Use an external power source

26
Q

Analog sensors

A

They give as output continuous signals

27
Q

Digital sensors

A

They give as output a discrete signal

28
Q

Proprioceptive

A

Sense the robots own parts

29
Q

Exteroceptive

A

Sense the outside world of the robot

30
Q

Inductive sensors

A

Detect metallic and measurement range is short (mm)

31
Q

Parts of a inductive sensor

A

Inductor, Oscillator, Trigger, Output Circuit

32
Q

Capacitive Sensors

A

Detects Metallic, non-metallic, objects of any type the potentiometer alters the range of measurement

33
Q

Parts of capacitive sensor

A

Capacitor, Oscillator, detector, output

34
Q

Photoelectric Sensor

A

Beam of light to detect the presence or absence of an object, long distances, and the object doesn’t need to be metallic

35
Q

Parts of a photoelectric Sensor

A

Emitter, Receiver, detector or comparator, output

36
Q

Types of photoelectric sensors

A

Opposed, retroreflective, diffused

37
Q

Opposed sensing

A

The emitter and receiver are housed separately and the detect the object que it interrupts the light beam, highest range

38
Q

Retroreflective sensing

A

The emitter and the receiver are in the same body and it detects the lights using a reflective element

39
Q

Diffused sensing

A

The emitter and the receiver are in the same body it detects the reflection of the sensed object

40
Q

Magnetic proximity sensors

A

It works using a magneto-resistive element that changed it resistance when subjected to a magnetic field it only detect magnetic and ferromagnetic objects

41
Q

Ultrasonic Sensors

A

Transmits and receive through sound waves used in long range applications for detecting films, transparent and liquid objects
