This attachment for the Nautiq robot is designed to collect the Trident Parts for M14, deliver the Shark for M02, and collect one Krill for M12 in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It features a passive trigger for the krill collection and aligns the robot with the mission model before collecting the trident parts.

This set of two attachments for the Nautiq robot is designed to collect and deliver the scuba diver for M01 Coral Nursery and M04 Scuba Diver, collect the shark for M02 Shark, and flip the coral reef for M03 Coral Reef in the FIRST LEGO League 2024‑2025 SUBMERGED competition. One attachment is mounted from above, and the other from below, allowing efficient execution of multiple missions in a single run.

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

Second part of the building instructions for this LEGO Mindstorms EV3 competition robot chassis

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.

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.

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

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.

This modification of the box robot contains large wheels. It was specially requested by you and we have it.

Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.

The frame contains parts from LEGO Mindstorms EV3.

Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.

When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.

Build with LEGO Mindstorms EV3 parts. 

Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things. 

The attachment could be built from LEGO Mindstorms EV3 and NXT parts. 

Building instructions for a LEGO robot that shoots 40 mm ping pong balls. The shooting mechanism is powered by two EV3 Large motors, while the whole mechanism is rotated by a medium motor. The robot can store up to 6 ping pong balls and has a Ultrasonic Sensor to detect targets. 

In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. The purpose of this attachment is to demonstrate How NOT to build attachments. 

Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand. 

This is a simple pinless active attachment for the SUV Box Robot.

In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.

While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.

This robot was built by your request. It includes NXT large wheels. The Large LEGOO Mindstorms wheels will give you a faster robot, but be careful, because it will not be that accurate. 

We had a couple of minutes before starting another robot and we just came up with this robot. If you would like to build a Box Robot, but don't have enough parts this is a good construction that you could learn from. It has a frame. It has three motors. You can add attachments at the top. 

This attachment uses a connector ("(98585) Technic Connector Circular With 2 Pin Holes and 3 Axle Holes") with 4 pins to connect with a knob wheel ("(32072 ) Technic Gear 4 Knob") of the robot. Because both elements are parallel one to another there is no jumping effect.

The attachment uses two pins, but it is easy to attach and detach because it uses "(6558) Technic Pin Long with Friction and Slot". When you attach or detach the attachment the slots are keeping the pins strong on to the attachment.

Also an attachment connected to the robot in this way, can be move to the rigth knob wheel or to the left knob wheel.

Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.
