Without the use of any motor, you can still accomplish a number of missions using passive attachments. You can still pull/push on different levers using only a beam or two connected to the frame.

This is the first Active Pinless Attachment for the Box competition robot. The attachment is placed on the top of the robot and is controlled by one of the motors. 

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. 

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. 

This robot could quite possibly be build from a single EV3 core and EV3 resource sets. It uses fewer parts and only three motors. There are additional parts that could be skipped when building the robot and we have added these parts only as to make the construction more complete. 

Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons. 

With the EV3 Mindstorms set you receive three motors. Two are large and one is medium. These three motors could be used in different configurations and in this video we show how to use the motors on the second box robot for competitions that we build. 

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 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.

The robot uses one middle motor. This middle motor with the use of a few gear systems controls for different axsels. We have attached wheels on this axles so it is very easy to extend the robot construction for additional LEGO Mindstorms active attachments
