Why are sensors important to robots?
They allow multiple commands to run in order
They give the robot information about its surroundings
They allow robots to repeat similar tasks
All of the above
What is the advantage of Sensor Control over Sequential Commands?
The robot can remember hazard areas
The robot can perform actions a lot faster
The robot can react to its environment
There is no big advantage
Look at the WAIT FOR TOUCH program below carefully.What does the robot do when the WaitTouch program runs?
Runs continuously until the Touch Sensor is pressed in
Waits for 1 second, then moves 1 rotation
Waits for the Touch Sensor to be pressed in, then moves 1 rotation
Runs for 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
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
Turn the motors off
Waits for the Touch Sensor to be pressed
Wait for the Touch Sensor to be pressed, then turn the motors off
End the program

Runs continuously until the Touch Sensor is pressed in
Waits for 1 second, then moves 1 rotation
Waits for the Touch Sensor to be pressed in, then moves 1 rotation
Runs for 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
By adding a File Block
Look at the program below carefully. If the robot is facing a wall, it will move until...
The Ultrasonic Sensor has traveled 50 cm
The Ultrasonic Sensor is 50 cm from the wall
The robot moves 50 cm total
The robot detects an obstacle beyond 50 cm away
What does this code do?
go forward until it "sees" something 30 cm away then stop
Move Backward until it "sees" something 30 cm away then stop
Reverse 50 rotations
go forward 50 rotations

I want my robot to move forward until it finds the colour green, and then stops. Which coding will do this?
What will this code make the robot do?
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 pressed, then go slowly backwards
Go forward quickly until the touch sensor is bumped, then go slowly backwards
