2 Veteran RoboParade team members and coaches Rookie teams that took Oct 9 workshop at Lawrence Tech This workshop is for 2

3 Tribot Light sensor: 3 Sonar sensor: 4 Left motor: A Right motor: C Additional motor: B Robot to be used 3

4 Endless loop – If sonar sensor detects an object Stop! – Otherwise Follow a black line Review – Parade Program 4

5 Review (2) – Parade Program 5 Power: 50

6 Flat View of the Parade Program 6

7 for NXT-G 2.1 users: broken file error (1003) can be fixed by rewriting the code. Please rewrite the program to review 7

8 How and Where to start the robot? 8 AC

9 9 AC

10 10 AC Lost…

11 Always safe to start on the line! 11 CA

12 More reliable line following? Use two light sensors! 12 Solution is available on tech resource/ workshop 1 / slide 23www.robofest.net

13 How to make it go smoother? (without using additional light sensor) 13

14 Lets test on the test course 14

15 Registered spectators will be given a ballot (go to: and click on schedule to register online)www.lorenzoculturalcenter.com Teams will introduce Robotic floats During the 2 nd Official Parade: – Floats violating the traffic law will be removed – People will select best float from only remaining robots RoboParade Peoples Choice Award 15

16 Reliable line following is important – check light values Do not hit the robot in front – check sonar sensor value Test, test, and test!!! First thing for Peoples Choice Award 16

17 Check the sonar sesnor range – Inch – cm Cover the back of the robot with paper for the robot behind you Meet the robot team in front of you: ask them to cover the back May need to adjust your sonar sensor location based on the robot in front of you Why not detecting the front object, sometimes? 17

18 Watch Previous RoboParade Videos – See Pictures – Think something Wow in order to win the Peoples Choice Award Ideas for floats 18

19 Decorations: You may use additional independent batteries for lighting You may put anything on your float Musical Instruments – Castanets – Triangles – Tambourines – Drums –…–… Movements on the float: use additional motors Ideas for floats 19

20 How to operate additional motors while following the line? 20

21 Move the mouse on the beam Press shift, the you will see a spool Drag and connect (click or double click) How to connect a parallel sequence beam? 21

22 Wireless interaction between the robot and team players is strongly encouraged Sound sensor: claps, knocks Light sensor: flashlight Sonar sensor: hand waves Interaction with your robot 22

23 Difficult to follow the line, if too long and too heavy In addition, it will make it difficult for the robot behind you to detect you Comments on Trailers 23

24 Make a train with many smaller trailers, if you want to build a long float You may use strings to connect trailers for flexibility Trailer II 24

25 Trailer III – Heavy Object 25

26 Robot speed requirements: 4cm/sec ~ 18cm/sec (not too slow, not too fast) You cannot join the official parade unless your robot pass the test on: – Friday, November 19, 5:00 pm – 8:00 pm – Saturday, November 20, 10 am – Noon (for this slot, teams must make an appointment) If you pass the test, you will be given an official flag Remember 26

27 A team can enter only one robot float If you have more than one float, then you must enter another team All family members must be registered through Lorenzo Cultural Center to enter the event hall. Online registration available at Note to Coaches 27

28 Happy 28
