How to on 'Easy Detach of Modules' in LEGO Mindstorms. Example with SUV Box Robot

We've recently received a number of question on how could the SUV box robot be charged. The answer is simple - you detach the back pane. The question and topic of detaching modules from a robot and attaching them again is really interesting and powerfull and yet not very often implemented in many robots.

Detaching modules

Building your robot as a collection of different modules gives you the ability to detach and attach parts of the robot, to reuse and to make your design much more agile. And agile designs are easier to modify to answer the new requirements. 

Detaching modules is not a new concept and in LEGO Mindstorms it is easily implemented. There are "Techin Pin Long with Stop Bush" that could be used for this.


The example above shows you how to easily detach the back pane of the robot and to allow for the robot to be charged. There are 6 Pins that should be pulled and then the pane. 

How many pins for locking

It is a good practice to use 2 pins for each side where your module is connected. In our case we are attaching the module on 3 sides so we have 6 red pins with Stop Bush.


SUV Competition Box Robot from LEGO Mindstorms EV3

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
