6 Quick Tasks Inputs and outputs only - Complete Palette Task now try the following song - and see if you can work out the timing on your own C C C C B C C B C D E D C C C C B C C -G C C C C B C C B C D E D C C C C B C C -G Chorus C D -G G F E D E F E D C B C B A B C D -G G F E D E F E D C B C B C D Were you able to recognise the song? Y N use the template below to assist you with the timing - then add your own for the chorus C C C C B C C B C D E D C C C C B C C -G Were you able to work out the rest of the timing? Y N Task 39 [ for this tasks - your teacher will provide you with a sheet of colour to drive over - or you'll use the training mat ] - use the tribot model ( or any other model ) - add a colour / light sensor to the model - program the model using the key below to play sounds as it moves over a series of colours Key suggestions C D - set the power for the motor to 20 E - play each sound for 2 seconds G - untick Wait for Completion Vol = 0 - play white with volume at 0 OFF - play all other sounds at full volume HINT 1 Use embedded if statements - in 1 continuous loop - with a sperate task to move the motor forward. Were you able to program the robot to play the music? Y N Do you need some more help? Y N If so, turn over to the next page. Page 17

7 Quick Tasks Inputs, outputs and data wires Build and use the Tribot or the HotBot Model ( or any similar model ) for the tasks on this page. Task 50 - copy both programs below and download them to the NXT for testing Program 1 Program 2 - place your model about 2 metres away from a solid object and run program 1 followed by program 2 - record your observations below : ( test each program at least twice ) Program 1 Program 2 Is the starting speed the same? Y N Y N Does the model stop before the object? Y N Y N Does the speed of the model change? Y N Y N Does the speed depend on the distance of the object? Y N Y N How far from the object does the speed first change? How far from the object does the model stop? What colour data wire was used? - can you think of reasons / situations where one of these options may be better than the other? Y N Keep your model and these programs for the next task! Page 22
