ICT Prep1 2nd Term Lesson 2 : Sensors

Sensors are .

• devices used to decorate robots.

• devices that sense changes in the environment and convert them into signals.

• devices used to operate electrical appliances.

• devices used to store data.

In robots, sensors help to .

• powering robots

• give robots mobility

• enable robots to understand and interact with their environment

• store information collected by the robot

is not an example of a sensor.

• Temperature sensor

• Light sensor

• Electric motor

• Sound sensor

is the first step in the work of the sensor.

• Sending signals to another device

• Converting signals into electrical signals

• Making a decision based on the sensed information

• Sensing changes in the environment

Ultrasonic sensors are used in vacuum cleaner robots for .

• determining the color of objects

• measuring room temperature

• determining the distance between the robot and obstacles

• controlling the suction power

The main function of the sensor is ..................

• store data

• capture environmental changes and convert them into signals

• display images

• produce sound

Sensors help robots to ...............

• teach them new languages

• allow them to interact with their environment

• increase their size

• slow down their operations

................ is a type of sensors used to avoid obstacles.

• Light sensors

• Sound sensors

• Distance sensors

• Heat sensors

The first step in the operation of the sensor is ..................

• transmission

• displaying

• sensing

• signal conversion

................ are commonly used in remote controls.

• Ultrasonic sensors
