Programming level 1

Build a ramp with a marble run path & Build a mechanical marble catapult & Build a „marble sweeper” with two figures on it

P1

How to build

Ramp with a marble run path

• It can be achieved by movable parts without robotics
• Baseplate, multibase or beams can be used for building
• Build a mechanical boom barrier (axle) to close/open the way of the marble

Mechanical marble catapult

• Use beams and axles for building
• Try to launch the marble by affixing the axle to different points of the beam

"Marble sweeper” with two figures on it

• Build a car with 2 DC motors
• Add a scoop and two boys to it
• The „marble sweeper” should move automatically

Programming level 2

Build a ramp with a marble run path and a motorized boom barrier

P2

How to build

Ramp with a marble run path and a motorized boom barrier

• Baseplate, multibase or beams can be used for building
• Build a boom barrier moved by servo motor to close/open the way of the marble
• The barrier should open when a Touch Sensor is pressed. A LED sould signal the moment of starting the marble

Robotic catapult

• Use a servo motor for launching
• The movement begins at the press of a button

Directable „marble sweeper”

• Build a car with 2 DC motors
• Add a 4-Touch sensor remote control to it
• Add a scoop and two boys to it

Programming level 3

Build a ramp with a random marble run path and a motorized boom barrier & Build 5 boys playing with marbles & Build a directable marble collector

P3

How to build

Ramp with a random marble run path and a motorized boom barrier

• Baseplate, multibase or beams can be used for building
• Build 2 barriers moved by servo motors to close/open the way of the marble.
• Randomly chosen, one of the barriers should open when the Touch Sensor is pressed. A LED should signal the chosen barrier and the moment of starting the marble

5 boys playing with marbles

• Build 5 small figures standing on the button of 5 Touch sensors
• Use 5 servo motors for launching
• Each figure should launch a marble when its Touch sensor is pressed

Directable marble collector

• Build a car with 2 DC motors and add two boys to it
• Add a 4-Touch sensor remote control to it
• It should have a marble collector arm moved by a servo motor and controlled by a 5th Touch sensor
• A Buzzer should make a sound every time the arm collects a marble

Programming level 4

Build a ramp with random automatic junction and a motorized boom barrier & Build a directed catapult & Build a „smart” marble collector

P4

How to build

Ramp with random automatic junction and a motorized boom barrier

• Baseplate, multibase or beams can be used for building
• Build and program the barrier at the beginning of the path as in P1
• On its path the marble hits another barrier that is equipped with an IR Photoreflector and opens the path for the marble when it detects it.
• When the barrier opens, it should randomly choose between 2 paths.

Directed catapult

• Use 2 servo motors: 1 for launching and 1 for aiming
• The movement begins at the press of a button
• The launching structure should rotate left and right with 2 more Touch sensors

„Smart” marble collector

• Build a car with 2 DC motors and add two boys to it
• Add a 4-Touch sensor remote control to it
• It should have a marble collector arm moved by a servo motor and controlled by an IR Photoreflector (the arm should make the collecting movement when the IR Photoreflector detects a marble )
• A Buzzer should make a sound every time the arm collects a marble
• The robot should count the collected marbles. The robot should stop when 5 marbles have been collected.
