TOUCH SENSOR AND ULTRASONIC SENSOR

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 the Basic Movement Commands?

• The robot can use little to no battery power.

• The robot can levitate if enough sensors are used.

• The robot can react to its environment.

• There is no big advantage.

Why might the Distance Sensor be preferred over Touch Sensors for detecting walls and obstacles?

• Hitting a wall could damage the wall

• Hitting a wall could damage the robot

• It is quicker to detect obstacles at a distance

• All of the above

Which sensor capable of detecting how far or near it is from an object/obstacle?

• Touch Sensor

• Ultrasonic Sensor

• Gyro Sensor

• Color Sensor

What does the wait-Sensor block allow you to do?

• Allow the robot to keep doing what it was doing until what the command is set to wait for has happened

• Force the robot to stop until what the command is set to wait for has happened

• Wait for an until command block to be processed before moving on

• Wait is not a valid name for a command

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 will the robot do based on the program?

• The robot will move forward until the Ultrasonic Sensor is 10 inches near an object, then the robot will stop.

• The robot will move forward until the Ultrasonic Sensor is 10 cm near an object, then the robot will stop.

• The robot will move forward until the Ultrasonic Sensor is 10 cm away from an object, then the robot will stop.

• The robot will move forward until the Ultrasonic Sensor is 10 inches away from an object, then the robot will stop.

What will the robot do based on the program?

• The robot will move forward for 1 rotation.

• The robot will move forward while waiting for the Touch Sensor to be pressed.

• The robot will move forward while waiting for the Touch Sensor to be released.

• The robot will move forward while waiting for the Sonar Sensor to bump an object.

What are the two (2) units of measurement of Distance Sensor?

• kilometers and inches

• kilometers and centimeters

• centimeters and inches

• inches and meters

What are threshold values accepted by the Touch Sensor?

• 1, 2, 3

• 2,3,4

• 0, 1, 3

• 0, 1, 2
