Why are sensors important to robots?

They give the robot information about its surroundings

They allow multiple commands to run in order

They allow robots to repeat similar tasks

What is the advantage of Sensor Control over Sequential Commands?

The robot can react to its environment

The robot can remember hazard areas

The robot can perform actions a lot faster

Look at the WAIT FOR TOUCH program below carefully.What does the robot do when the WaitTouch program runs?

Waits for the Touch Sensor to be pressed in, then moves 1 rotation

Runs continuously until the Touch Sensor is pressed in

Waits for 1 second, then moves 1 rotation

Look at the WAIT FOR TOUCH program carefully. The program waits BEFORE it moves because...

The Wait Block comes first in the program

The Wait Block always takes priority over Move Blocks

What does a Move command do when its Mode is set to “On” as shown on the program?

Turn the motors on for a certain number of rotations

Turn the motors on until the Touch Sensor is triggered

Combines with the next block to make a special command

What does a Move command do when its Mode is set to “Off”? See the image

Waits for the Touch Sensor to be pressed

Wait for the Touch Sensor to be pressed, then turn the motors off

Look at the WAIT FOR TOUCH program carefully. What does the robot do when the WaitTouch program runs?

Waits for the Touch Sensor to be pressed in, then moves 1 rotation

Runs continuously until the Touch Sensor is pressed in

Waits for 1 second, then moves 1 rotation

Look at the WAIT FOR TOUCH program carefully. The program waits BEFORE it moves because...

The Wait Block comes first in the program

The Wait Block always takes priority over Move Blocks

What does the Wait Block wait for before playing the "Hello" sound on the program below?

The Ultrasonic Sensor to detect an object less than 50 cm away

The Ultrasonic Sensor to detect an object more than 50 cm away

The robot to travel less than 50 cm

The Ultrasonic Sensor's reading to change by up to 50 cm

How do you select the sound file the robot plays on the program below

By clicking in the upper-right "File Name" blank on the block

By speaking into the speakers of the EV3

Look at the program below carefully. If the robot is facing a wall, it will move until...

The Ultrasonic Sensor is 50 cm from the wall

The Ultrasonic Sensor has traveled 50 cm

The robot detects an obstacle beyond 50 cm away

What does this code do?

Move Backward until it "sees" something 30 cm away then stop

go forward until it "sees" something 30 cm away then stop

Why are sensors important to robots?

They give the robot information about its surroundings

They allow multiple commands to run in order

They allow robots to repeat similar tasks

Which of the following actions can be programed using the touch sensor?

Pressed and Released Just Before (Bumped)

What will this code make the robot do?

Go forward quickly until the touch sensor is pressed, then go slowly backwards

Go forward for 1 second, then move backwards

Go forward quickly, wait 1 second, then backwards slowly

Go forward quickly until the touch sensor is bumped, then go slowly backwards
