Tracked robotic base "Ryszard"

Hello!

This is my first bigger project. I decided to design modular tracked platform with provided mountpoints. Track link geometry was borrowed from Drogerdy Raspbery Pi robot (http://www.thingiverse.com/thing:652851). To connect links you need 2mm diameter metal rods (i used bike spokes).

I am using Pololu 37D motors (https://www.pololu.com/product/2826). Due to the size and weight each bigger wheel need two 10x15x4 bearings, and each smaller wheel one 5x10x4 bearing. Motor-Wheel connection is realised by two M4 grub screws (Place for M4 Nuts is also provided). To connect Frame Parts you need M3 screws.

Final dimensions of fully assembled platform:
336 mm long
237 mm wide
78 mm height


Update 0.1

-Added floor
-Added Arduino Mega Mounting plate
-Added flap in floor to easy acces to Arduino (mounted by four 4mm diameter and 4mm height neodymium magnets )
-Changed geometry of Track Assembly Connector, Frond Connector and Rear Connector

I bought a lot of filament
