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 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.

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.

Playing Football with robots is extremely fun. It could be part of the classes, it could be part of demonstration days. The Striker is a robot for handling the ball and attacking the goalkeeper.

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

The goal of these building instructions is to build a simple LEGO Mindstorms EV3 robot without wheels. You should then think of yourself how exactly to add the wheel. Which wheels would you use on the front? How are you going to build the third wheel? Here are for example a few recommendations on building the third wheel - 1, 2, 3, 4 

Later on you can expland this construction with a grabber as demosntrated here. 

Accomplish three FIRST LEGO League missions at once. This is an interesting Large multi-purpose FLL attachment for a box robot that could be used to accomplish a number of missions with a single exit of the field base. 

This is an attachment for the cases where you need a two touch bumper sensors. It could be placed on almost any LEGO Mindstorms EV3 robot.

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. 

Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.

Here is another great example of a large multi-purpose attachment used in FIRST LEGO League competitions. This one is specifically for the 2017-2018 Hydrodynamics competitions and is doing a number of missions. (01) Pipe removal, (06) Water Treatment and (08) Manhole cover. 

The attachment consists of two parts. The first part is placed on the robot while the second part is in front of the robot and the robot pushes it. While working on the field the robot leaves the second part on the Water Treatment plant and when returning back collects it back and returns to base.

The goal of the attachment is for you to build it and experiment with it with the existing field. Use Box Robot 2 as a robot base on which to add the attachments.   

Building instructions for a simple chain tread machine. The robot is actually a simplified version of the Freedom Folk Race tank. All of the ultrasonic sensors are stripped away and the robot can be used for multiple different tasks. The construction is appealing to students and simple enough to be included in a class.

A robot that was used in the WRO Elementary 2018 Robot competition. It is a nice idea of how the motors could control different levers to push things around

Probably the largest multi-purpose FLL attachment at FLLCasts. These attached is doing a number of missions at once. 4 of them. You attach it to the robot and start the program. The robot moves and accomplishes a number of missions using only this attachment. At it also has a lot of parts. It is quite large and you can not build it from a single set. But that's ok because you are preparing for a competition, right?

This was an idea. You would we demonstration a multi-axle power and rotation transmitting box. Well, here it is. Build it. Start it. And see how the power from the motor is transmitted through different axles. The lever will demonstrate it.

We love bears. These are great creatures. Do you know that the Polar Bear is the largest bear there is. 

This robot was first constructed years ago for some of the first classes in LEGO Mindstorms Robotics that we held. It is quite challenging, but nevertheless very rewarding when completed and when you manage to program it to walk. Check it out. 

These are building instructions for an attachment accomplishing the FIRST LEGO League 2017-2018 Slingshot mission. The based of the robot is LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro

Two missions in one. This attachment accomplishes the Hydrodynamics Fountain and Faucet missions from the FIRST LEGO League Hydrodynamics 2017-2018 competitions. The attachment shows a really interesting and widely used approach of a single attachment that is used for two, three and even more missions. This is a standard practice for many of the advanced teams, especially those that reach the finals. The based of the robot is the LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro
