Language

The programming language in CeeBot is very similar to Java, C++ and C#. It has been developed especially to make learning programming easier. Its syntax may seem somewhat complex, but the idea is to learn a well-known programming technique. All knowledge acquired here can be used in everyday professional programming.

Here's a sample of the instructions used in CeeBot :

if/else	Choice structure
repeat	Repetition structure
for	Repetition structure
while	Control stucture
do	Control stucture
radar	Object detection
direction	Work out a direction
distance	Calculate a distance
wait	Wait
move	Forwards (+) or backwards (-)
turn	Turn left (+) or right (-)
goto	Go to a specific position
motor	Direct commands for the motors
jet	Direct commands for the jet propulsion
message	Display a message

pendown	Lower the pen to start drawing
penup	Lift the pen up to stop drawing
pencolor	Color of the pen
penwidth	Size of the pen's tip
grab	Take an object
drop	Put an object down
fire	Shoot with the robot's weapon
receive	Receive data from an information post
send	Send data to an information post
class	Declare a class
public	Indicates a public function
private	Indicates a private field
static	Indicates a static field
new	Creates a new instance
this	Refers to the current instance

pendown

This instruction is used to draw on the ground. The robot has a pen that leaves a line behind it when it moves. You can define the line's width and color.

pendown(Red);  // Use a red pen
repeat(4)      // repeat 4x
{
  move(20);    // draw a straight line
  turn(90);    // turn 90 degrees left
}

grab

Some bots have a swivelling arm that can pick up and move objects.

object item;
item = radar(Titanium);  // find metal
goto(item.position);     // goto to the metal
grab();     // pick up the metal
move(-10);  // reverse 10 meters
drop();     // put the metal down

fire

Some bots have a canon used to destroy training targets or undesirable insects.

while(true)     // repeat forever
{
  motor(1,-1);  // turn right
  fire(2);      // shoot for 2 seconds
  motor(-1,1);  // turn left
  fire(2);      // shoot for 2 seconds
}
