Building Instructions

Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.

These are 3D Building Instructions for M12 Forest Elder mission model for the FIRST LEGO League 2026-2027 BIOGLOW competition.

The first part of a box robot chassis for robotics competitions. The robot is quite large and this is why we split it into two parts - to make it easier to construct it. This is the second part. 

The robot is built with LEGO Mindstorms EV3, with an additional part for the walls used in the second part.

These are 3D Building Instructions for M06 Leafcutter Frenzy mission model and M07 Humongous Fungus mission model for the FIRST LEGO League 2026-2027 BIOGLOW competition.

Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.

Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.

These are 3D Building Instructions for M10 Fragile Microhabitats mission model for the FIRST LEGO League 2026-2027 BIOGLOW competition.

This is a real competition robot with three light sensors and a gyro.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and is used in the FIRST LEGO League 2025-2026 UNEARTHED competition. It completes Mission 13: Statue Rebuild, collects the other team’s minecart, delivers a flag next to the minecart extraction area, and transports all artifacts from the Right Base to the Left Base.

Building instructions for a Full LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions.

These are 3D building instructions for an alternative M12 Salvage Operation mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M12 Salvage Operation.

These are 3D building instructions for an alternative M05 Who Lived Here? mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M05 Who Lived Here?.

The very first robot that we usually build in a class. 

The "five minute bot with handle" gives an easy and intuitive place for children to hold it. It provides a stronger construction and cables are not included, so that adult assistance with the cables at the end of the building process is required.

These are 3D building instructions for alternative M03 Mineshaft Explorer and M04 Careful Recovery mission models for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original combined mission model, see M03 Mineshaft Explorer and M04 Careful Recovery.

These are 3D building instructions for an alternative M10 Tip the Scales mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M10 Tip the Scales.

This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments!

It's has "V2" in its name, because it's the second version of Whakatae - LEGO Education SPIKE Prime Competition Box robot. The difference between the two is that the first one can be built with only a Large Motor and a Color sensor in addition to the Base set, while this one needs an additional ball bearing. This provides this robot with a lot more stability and can be seen as a true upgrade to the first version.

"How do you build a forklift using only gear wheels and levers without a rake"... Ok, we would admit that is a difficult question. It even sounds difficult. So let's start with something easy. A LEGO Mindstorms EV3 robot. It lifts objects in the air. It uses two gear wheels that work together and then move in different directions and are placed perpendicular to each other... This sentence kind of got difficult again... Let me try again.

Follow the building instructions with these 70+ steps and you will have a very nice robot and you will learn a simple trick of how to use gears and change the directions in which they rotate.
