The digital EV3 [blank_start]Ultrasonic Sensor[blank_end] generates [blank_start]sound waves[blank_end] and reads their [blank_start]echoes[blank_end] to detect and measure distance from objects. It can also send single sound waves to work as [blank_start]sonar[blank_end] or listen for a sound wave that [blank_start]triggers[blank_end] the start of a program.
EV3 [blank_start]Color[blank_end] Sensor It also serves as a light sensor by detecting light [blank_start]intensities[blank_end]. Students can build color sorting and line-following robots, experiment with light [blank_start]reflection[blank_end] of different colors, and gain experience with a technology that is [blank_start]widely[blank_end] used in industries like [blank_start]recycling[blank_end], agriculture and packaging.
We could say that the robot is similar to the human being since it works with sensors that are similar to the human senses.
