My lego catch

It is a robot that serves to recover your lego in its first part. I tried to add more details I rarelly amuse myself to make this challenge. 

First drawing: THE ENGINE SYSTEM 

It consists of a large pinon that drives another gear throught an oak.The driven pinion on the same bar as our  wheel made of oak.

Second drawing:BRIGHNESS 

Once the engine is on you can have several bright places to bring  charm  to the robot.

Third drawing: SPEED

You have to turn on the robot to get speed.  

Fourth drawing: HIDEOUT

For design I chose to add a hatch for hidden vacuum.

Fifth drawing: DESIGN

It's  very simple.

Sixth drawing: FINALLY 

Here is the robot.
