 Articulated mechanics 

Realization

After following many episodes of Robotica I was fascinated by one of the winners: Flexy Flyer. It is so simple and efficient on going everywhere and “over” everything. Starting on self-constructing an outdoor robot, this is the mechanical configuration I’ve thought about.
The most important thing on this kind of articulated chassis robot is the central hub. There are a lot of flanged bearings available, different quality, precision and, of course, costs.

A very robust and cheap one can be found at Profibohrer on-line shop. My choosing process started from the central hole size, it must be large enough to allow all the connections between the two parts. This is a selection of square flange bearing. A little bit heavy, but robust more than enough. A couple of them joined with a pipe, make the right joint for this robot.

The project for the mechanic structure goes ahead. The complete Google SketchUp project is available here. It contains many layers that allows you to view every details, included quotes for exact measurements.
