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 an alternative M09 What’s on Sale? mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M09 What’s on Sale?.

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 an alternative M11 Angler Artifacts mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M11 Angler Artifacts.

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 an alternative M08 Silo mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M08 Silo.

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

These are 3D building instructions for an alternative M02 Map Reveal mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M02 Map Reveal.

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 M15 Site Marking mission model for the FIRST LEGO League 2025-2026 UNEARTHED competition. For the original mission model, see M14 Forum and M15 Site Marking.

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

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 12: Salvage Operation and part of Mission 15: Site Marking in the FIRST LEGO League 2025-2026 UNEARTHED competition. It raises the ship, pulls the sand lever to clear the sand, and places a flag in its designated position next to the Salvage Operation mission model.

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.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 14: Forum and Mission 15: Site Marking in the FIRST LEGO League 2025-2026 UNEARTHED competition. It delivers all the artifacts to the Forum and places the flag in its designated position nearby.

The instructions for building the improved EV3 Competition Robot by Mic Lowne

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 09: What’s on Sale? in the FIRST LEGO League 2025-2026 UNEARTHED competition. It pulls the horizontal axle to raise the roof, then presses the lever to lift the wares.

"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. 

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 10: Tip the Scales in the FIRST LEGO League 2025-2026 UNEARTHED competition. It releases the large scale, latches onto the Scale Pan, and transports it safely back to base.

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.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 11: Angler Artifacts in the FIRST LEGO League 2025-2026 UNEARTHED competition. It aligns the robot with the Angler Artifacts mission model and rotates the gear mechanism to raise both the artifacts and the flagpole.
