Touch Sensor

Challenge 1 Design and program your robot to move forward and stop when the touch sensor is touched. Hint: You will combine: Move Steering + Wait Block

Challenge 2 Part A: Program your robot to move until it hits the edge of a wall. Then back up and stop Part B: Program your robot to move until it hits the edge of a wall. Then back up and stop

Challenge 1 Part a: Have your robot say “go” and have it travel 15cm, then have it stop and say “stop”. Part B: Have your robot travel 15cm, then have it display an image. Part C: Have your robot travel 15cm, then have it display a text.

Challenge 2 Design your robot to move forward, stop, then reverse with a warning light and warning sound indicating it is moving in reverse using the brick status light.

Challenge 3 Deliver a message to Mr. Fava using your robot. Record your own message and have the robot stop and say it once Mr. Fava “bumps” the touch sensor.

Challenge 4 Place both touch sensors on your bot. Design and program a robot that moves forward, and when the robot “bumps” into another object the robot will back up and turn and continue in a different direction.

Challenge 5 Drive your bot with your touch sensors as a remote control. Have the right touch sensor control the right motor and the left touch sensor control the left motor.

Ultra Sonic Sensor (Wall-e) Unattached the touch sensors and place them in your bins. Next attach the ultra sonic sensor to the Front of your bot. Make sure the ultrasonic sensor is attached securely – it should not move around. Help each other out attaching. Look at the next slide for ideas

Ultra Sonic Challenge 1 Make the robot move until it is 20 cm away from the wall. Hint: Use the wait for block

Ultra Sonic Challenge 2 Part a: Make the robot move until it is 20 cm then stop, back up and make a warning sound with a flashing light. Part B: Make the robot move until it is 10 cm then stop, back up and turn around and head in a different direction for 5 seconds.

Ultra Sonic Challenge 3 – “Luke I am your father” Use the force to control your robot! If the robot is closer than 20cm away from your hand move backward, otherwise move forward. Hint you will need a Loop

Avoiding objects Challenge Have your bot move through the straight away portion of the track on its own, without knocking into any of the objects.

Color/Light Sensor

What is the Color Sensor? What are they? Sensors that detect the intensity of light that enters it Three modes: Color, Reflected Light Intensity and Ambient Light Intensity Color Mode: Recognizes 7 colors (black, brown, blue, green, yellow, red, white) and No Color Reflected Light: Measures the intensity of the light reflected back from a lamp that emits a red light. (0=very dark and 100=very light) Ambient Light: Measures the strength of the light that enters the sensor from the environment. (0=very dark and 100=very light)

Attach your color sensor You want you color sensor facing the ground, and to be as close as possible to the ground.

Colors and Numbers

Challenge 1 Part A Have your bot move forward and stop at the green line. Part B Have your bot move forward then turn around in the other direction when it reaches the blue line.

Challenge 2 Part A Have your bot move forward, and as it reaches each color line, have it stop and say the color of line it has just passed. Part B Same as part a, but have it stop on each line, say the color, then continue to move.
