Building instructions for a LEGO Mindstorms EV3 Multi-axles mechanism

If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.

Built from LEGO Mindstorms EV3 parts. 

Advanced LEGO MINDSTORMS EV3 Construction. It has two rear motors and it could rotate the whole from part. It has 4 wheels and is kind of like unique in the Mindstorms world.

Building instructions are not very easy and you need LEGO Education Core and Extension Sets - 45544 and 45560. 

Apart from being advanced, it is also quite fun to try to build.

You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.

This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.

The rotation frame requiers an NXT large double gear wheel that is not available at the EV3 set. You can use the instructions below to construct a similar mechanism from Mindstorms EV3 set

These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.

A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.  

This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.  

One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.

This is a simple LEGO Gear System with a ration of 1:5. When the large wheel rotates 1 time the small wheel will rotate 5 times.
