Each team is provided with a standard kit of parts.

This consists of over 1200 Lego pieces, along with sensors and other components useful in building an autonomous robot.  All these parts are listed below, with details of where to find them.

Other electronic components are available in the laboratory, for those who want to build their own sensors.

Tools, insulating tape, elastic bands and other items are also available in the laboratory.  The competition rules restrict how you use some of these items.

At the end of each laboratory session, please put all the parts and the robot the large storage box provided.  Please leave the robot, charger and cables accessible in the box, so that they can be charged before the next lab session.  The Handyboard should be switched off and disconnected from the charger - otherwise the battery will be not be fully charged at the start of the next lab session.

After the competition, the kit must be returned in good condition, with all parts sorted as they were at the start.


Parts Lists

Structural parts Motion parts Electrical parts
Bricks Wheels Motors, actuator & accessories
Plates Axles & accessories Switches
Beams (also called Arms) Gears Optical Parts
Pins & Bushes  Pins & Bushes Handyboard & interface



Most of the small parts are in bins in a plastic case.  Each bin can be removed from the case if necessary.


Please close and lock the case when not in use!  These small parts are hard to collect from the floor!

The Handyboard is the computer that controls the robot.  It contains a rechargeable battery to provide power for itself and for the motors and other parts that it drives.

The Handyboard has many connectors:
inputs for signals from sensors;
outputs for driving motors and servos.

Handyboard manual

The interface unit connects the Handyboard, the power supply unit and the computer that is used to program the Handyboard.

It has three indicator lights - all three should be ON when it is connected properly:
Green => computer connected (blinks when active)
Red => interface unit has power;
Yellow => Handyboard battery is charging.

The power supply unit provides an unregulated DC supply, nominally 12V, to power the interface unit and charge the Handyboard battery. not available
