Building Instructions

Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.

The left attachments work synchronously, and the right attachments are also synchronized couple.

These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us. 

This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.

The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.

Attachment frames are used on Base Robot Chassis to make it easier to add and remove attachments very fast. This frame is for the Box Robot 1. It is a single module build with LEGO Mindstorms EV3 parts and it could handle attachment on all sides. 

We experimented with building a box robot powered entirely by chains—a unique approach inspired by the original LEGO MINDSTORMS NXT Robots. Chains like these can be hard to find, but we thought: why not try to power both the robot and its attachments with them? This design not only powers the entire robot but also provides a great demonstration of how and when chains can be effectively used in robotics.

To build this robot, you'll need approximately 180 chain links (part 3711a), which are available in the NXT kits and some Technic sets.

Please note that this robot requires additional components beyond those included in the LEGO Education SPIKE Prime and SPIKE Essential kits. Check out the additional parts required.

The Sports Utility Vehicle box robot is the new marvelous box robot that we've created. It is designed for teams that would like to learn how to build balanced, stable and working robot chassis following our box principle. It is smaller and easier to build than box robot 1 and it is more simple than box robot 2. 

The main advantages of this robot compared to previous box robots are 

 - motors in the right direction, so when rotating the motor forward, the robot moves forward.

 - it is much easier to attach attachments. There are 4 different gears on which you could attach attachments. 

 - it has a large clearance - which means that it could move over obstacles.

Of course, it has a Gyro and two Color Sensors.  Not only that, but we have all the cables shown in the construction.

When not to use this robot?

The SUV Box robot is design to be used with a Gyro sensor and two Color Sensors for alignment. It is not working well for following lines as the sensors are very high and they are very high to allow for high clearance of the chassis. If you need to follow lines we recommend the Dominator X-Y robot

Introducing Kufar! In Bulgarian, Kufar means "suitcase," and just like a suitcase, this robot is easy to "pack" with different attachments for each task.

Unlike traditional box robots, Kufar is an "out-of-box" design, enabling fast, easy attachment swaps. This flexibility allows teams to build a new chassis with customized attachments for each run, making transitions quick but requiring more parts and careful handling due to its gear transmission, which can sometimes cause gear slippage or play.

To improve precision, Kufar’s gear transmission is optimized for lower speeds. Kufar also includes a color sensor to detect specific colored bricks on attachments and a force sensor to start corresponding programs. With two motors for movement and one for attachments, Kufar is compact, efficient, and easy to handle, especially with its sturdy top handle.

We thoroughly enjoyed exploring this innovative concept and hope you find it equally fun and inspiring!

Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions. 

The Chain Monster is one of the coolest Box Robots that we've built. But what is a robot without attachments that can accomplish missions? These here are 3D building instructions demonstrating how the frame for the robot could be built. We've discussed frames in the Box Robots courses for EV3. Take a look at this one. See if it can inspire you to build robots and attachments in certain way to achieve consistent and reliable robot behavior.

This is an attachment that accomplishes a mission. But they all do. This attachment is special as it is a Glide pinless attachment. It teachers the principles of building attachments that could be easily glided onto the robot and allow for quick changes of different attachments. It is designed for the

The MiniBox box robot features a unique design with three perpendicularly rotating gearwheels, which simplifies the attachment design process. This setup allows teams to easily create and connect attachments on multiple sides, making it quick to adjust the robot for various tasks.

Its structure includes walls with a maximum attachable surface area, offering flexibility in attachment placement. This extensive surface allows for secure connections, so teams can experiment with different attachment configurations.

The MiniBox’s compact size is best suited for smaller, lightweight attachments. When working with larger attachments, its balance and stability can be affected, limiting its effectiveness in tasks that require more substantial setups.

These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments. 

No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.

Build with LEGO Mindstorms EV3 

Vex IQ robot base which could be used with different attachments. The gravity center of this robot is in the backside and it has a lot of space in front for attachments.

We've built a box robot chassis that could easily be extended with attachments for FIRST Technical Challenge competition.

If you ever felt that FIRST Technical Challenge is difficult and you don't know where to start from, building this Tetrix robot is the first thing that you could do. You would have 4 motors, plenty of space for attachments and good access to the phone.

The robot is built from a Tetrix Set without additional parts. It's a winning robot in just 109 steps
