PROJECTS FOR SCRATCH & MOWAY
INSTRUCTIONS TO PROJECTS A"er every project, make sure you start a new Project from inside Scratch Projects will be released every Monday Answers will be released every Friday If you have doubts, check with your fellow friends first, then check with your teachers If you sall do not have a saasfactory answer, email to moway.support@lithanhall.com
Project #18 What are the different sensors in a moway robot? What is the type of sensor used by moway to detect obstacles in front? Where does moway robot get its power?
Project #19 Write a program in Scratch where every Ame we press one of the arrows on the keyboard, Scratch sends a movement command to moway. when the up arrow is pressed, the command sent is go, making the robot advance forward When the down arrow is pressed, the robot stops when the le" or right arrows are pressed, the robot turns 90º to le" or right, respecavely
Write a program in Scratch to make the moway robot move to form a square, both in the Scratch drawing and in reality Project #20
Project #21 Make the moway sprite move around the Scratch screen Mimic the movement of the moway sprite on the moway robot in physical world
Project #22 Write a Scratch program to acavate the LEDs on the moway robot The lights should correspond to the following keys being pressed: Lights Key Ac>on Front & Brake LEDs Up On Down Off Green LED Le" On Red LED Right On All LEDS Space Bar Off
Project #23 Write a program such that moway sprite is enclosed within the window and the real robot copies the sprite s movements. In this case, LED acavaaon is added, so that: When the robot moves forward, the front LED lights up. When the robot stops, the brake LED lights up When the robot turns le", the red LED turns on When the robot turns right, the green LED turns on. Every Ame a command is sent to acavate an LED, the robot drawing changes to the corresponding LED image. HINT: Use the different costumes of the moway sprite
Project #24 Create a Scratch script that when the moway robot reverses, it emits a sound from moway s internal speaker HINT: Use the different costumes of the moway
Project #25 Using the built- in microphone on the moway robot, create a Scratch script to detect the sound and display the sound level received by the microphone on the Scratch screen HINT: Use Sensor and Variables blocks
Project #26 Create a Scratch program to use the moway s microphone to mimic a sound meter It should display a meter similar to the one below HINT: use Sensor, Mo>on (point in direc>on) & Operator Blocks, and an Arrow Sprite
Project #27 Using the moway microphone, create using Scratch a sound recorder Display the sound received as a graph on the screen HINT: use the Sensor, Pen & Variables blocks, and 2 Sprites (Arrow and ) *(fill in the blank)
Project #28 Create a moon mission for moway robot It will hear a first sound and it will move unal it reaches the horizon, and a second sound will make it return to its starang posiaon HINT: In the exercise, use Scratch s move steps and change size blocks to simulate that moway is going away (shrinking) and approaching (enlarging). Also, use an imaginary black line at the horizon of the Moon to trigger the return of the moway
Project #28 (cont d)
Project #28 (cont d) Addi>onal Hints Download a sample moon surface picture from the Internet Use 2 sprites: a moway explorer and a black line, with the black line on the horizon of the moon surface When the up key is pressed, the explorer moves to wards the horizon of the moon and the explorer becomes smaller and smaller; the explorer stops when it touches the moon s horizon and the explorer turns around (180 ) When the down key is pressed, the explorer returns to its star>ng point; the explorer becomes larger and larger Instead of using the keys to ini>ate the explorer, use the sound received to ini>ate the explorer s movement
Project #29 Create a Scratch program to plot moway s obstacle sensors in a graphical representaaon as shown below (1 for each sensor) HINT: Sensor Block, Variable (x_posi>on), Pen Block. There will be 4 scripts, 4 sprites to generate the 4 graphs and 1 sprite for the background (stage)
