Circle See the program

How to draw a square. Move forwards 20 meters, then turn 90 degrees. If you do this 4 times, you'll get a square. To draw the circle shown here, we'll repeat "move forwards 2 meters" and "turn 10 degrees" 36 times . You'll notice this exercise introduces you to variables, an essential notion in programming.

Loop See the program

In this exercise, 6 targets are set up in a regular pattern. Use a repeat loop to shoot them all. Move forwards, turn left, fire the robot's canon, turn right and start again. Later on, we'll come across a for loop, which is more complicated. while and do/while loops will also be studied.

Drawing See the program

One of the first exercises was to draw a square. Little by little you'll be brought to more complicated figures. This example shows a geometric figure made of 12 squares. It brings up the concept of procedures.
The procedure Square() is called upon 12 times to draw this stylish flower.

Maze See the program

Leading a robot through a maze is a great classic. Your robot will use its radar to check if there's an obstacle in front of it, or to one side. Depending on the result, it will figure out if it can move forwards or needs to turn. This is a good example of how to use a conditional if branch instruction.

Path See the program

Your robots can gather data from information posts set along the path. This information is stocked in variables the robot can read as it goes. If you've got it right, your droid will zigzag safely between pools of burning lava and sheer cliffs all the way to the platform.

Array See the program

After having studied simple variables (int and float), this exercise brings up the more complicated arrays. Objects are stacked on 5 bases. Your robot must shift them around and bring them back in the reverse order. This means memorizing each object's position in a 1 dimensional array of 5 elements. Another exercise shows how to use 2 dimensional arrays.

Motor See the program

Each robot is equipped with 2 motors that drive it like a caterpillar's tracks. In this exercise, you must spot the closest blue cross, and then figure out at what speed each motor must run to drive the robot up to the cross. You'll notice how smooth and elegant the robot's motions are.
