Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features. 

One of the very good things about box robots is that you could easily align with them both to the front, to the back or to the rear sides. This aligning is helpful for FIRST LEGO League, World Robotics Olympiad or other robotics competitions with LEGO Mindstorms EV3/NXT robots. 

This is a video tutorial that demonstrates how to accomplish M06 and M07 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster box robot which is a LEGO Education SPIKE Prime robot equipped with an active attachment with gear wheels, which engage the mission model’s gears to rotate the respective parts. The entire run takes less than 3 seconds, delivering a neat and precise performance.

In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.

Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.

This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended. 

One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects. 

This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.

In this Episode, we create the next attachment for the box robot two. It is again a pinless attachment, attached to the frame that transfers the motion to a vertical axle. 

Need to transfer circular into a linear motion. You need a rack. Here is an attachment with a rack for our box robot.

Recap on the attachments, their purpose and how you should use them. 

Energy storage mission from FIRST LEGO League 2022-2023 is again a two parts mission where we have to drop a few energy units in the mission model, but we also have to pull part of the mission model. In this video tutorial we demonstrate how the Chain Monster LEGO box robot accomplishes this with a multi purpose attachment for box robots.

This is a 10 out of 10 tutorial in which the MiniBox robot accomplishes the M12, M13, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. The MiniBox is a LEGO Education SPIKE Prime box robot that uses detachable attachments.

In this run, the robot performs five actions: it collects the M15 minifigure and throws it backward, rotates the chicken for M12, and then pushes and pulls the M13 Craft Creator mission model. All of these actions are completed in under 15 seconds!

This one is very special- an attachment that could lock itself on purpose while working. 

Sometimes the way an axle is placed is just not suitable for a certain attachment and you should transfer the motion to another axle a few LEGO units above the current.
