1 Introduction

1.1 Minimal requirements

CeeBot requires a reasonably recent computer. It is particularly important to have a

good 3D graphic adapter for maximum performance.

• 300 MHz CPU, 64 Mb RAM

• 3D graphic card with 16 Mb RAM

• Sound card and loudspeakers or earphones

• 200 Mb free disk space

• Windows XP, 2000, ME, 98 or 95

• DirectX 8 (If necessary, CeeBot will install DirectX 8)

Recommended graphic cards :

• nVidia GeForce 2, 3 or 4

• Matrox G400, G450, G550 or Parhelia

However CeeBot3 will probably work reasonably well even on low-end onboard graphic

chips. 3dfx Voodoo graphic adapters are not officially supported, but they may work (no

guarantee). Some graphic chips in notebooks will not provide satisfactory performance.

1.2 To install CeeBot

• Insert the CeeBot CD-ROM in the drive

It should start automatically after ten seconds or so.

Click Install

If the autorun doesn't start, follow these steps :

• Double-click My computer

• Open the D : drive (where D: is the letter of your CD-ROM drive)

• Double-click Install

The installation process will check if you have DirectX 8a. If this is not the case, you'll

be prompted to install it.

If you have a previous version of CeeBot, a new installation in the same folder will

overwrite all data, saved games or programs.

1.3 To uninstall CeeBot

• Double-click My computer.

• Double-click Control panel .

• Double-click Add or Remove programs .

• Double-click CeeBot3 in the list.

2 First approach

The detailed explanations will be found in the following chapters. This is your very first

contact, to help you get familiar with CeeBot.

The first thing CeeBot needs is the player's

name. Each player must use a separate

name, because CeeBot saves your

programs and keeps track of your

progress. Choose the user name Teacher ,

so that you can access the settings and

the solutions for every exercise. Then click

OK .

CeeBot now lists the various exercises.

The left column shows the different

chapters, and the right column is the list of

the exercises in the selected chapter.

The exercises get progressively more

difficult. We suggest you try them in this

order, even though this isn’t compulsory.

Choose 1: Move ! and 1: Move 1 , then

click Play .

The green text at the top of the screen

asks you to press F1 to get the instructions

for the current exercise.

You can also click this button, at the

bottom of the screen:

The information displayed is the same as

in these pages. To close this window,

press the button in the bottom left corner.

If necessary, you can come back to this

screen at any time by pressing F1 .

In the lower left corner of the screen

select the first program in the list. Each

robot can have up to 10 programs. This

can be handy when you're testing

different solutions. All these programs are

saved automatically in each player's

profile.

Program number 10 (use the scroll bar)

contains one possible Solution for the

exercise. You can immediately execute it

with the following button:

To enter the program editor, click {..} . If

you selected program 10, you will see the

solution.

If you selected an empty program, the

editor comes up with an empty shell ready

for you to write your new program.

The text cursor is between the braces.

Do not alter the first line or the braces.

The exercise consists in tracing a 5 cm-

long line on the ground. First us e the

following instruction to lower the pen:

pendown();

Then move the robot 5 cm forward with

the following instruction:

move(5);

Click OK . If you've made a mistake, it will

be highlighted in blue, and a message will

be displayed at the bottom of the screen.

If everything is correct, when you click OK

the editor is closed.

Click this button to execute the program.

The robot should now lower the pen (it

becomes transparent so that you can see

what it draws), then move 5 cm forward,

leaving a black trace behind.

That's it, you just did the first exercise.

In order to leave the exercise, click the

cross button on the upper left side of the

screen (or push the Esc key), then click

Close .

You can now take a look at the following

exercises. There are more than 100

exercises, starting with the instructions to

control the robots. Then the students will

progressively learn to program animations

with hundreds of frames and a sound

track. They will finally apply all the skills

they have acquired in the final group or

class project, where every student can

contribute in the domain he or she likes

most.
