While I might be ahead of myself a little here I was asked to do a how to on the Robo Spot by Brian. I have not totally finished and tested the complete units so please don't start on these until then. I don't won't anyone to wasting their hard earned dollars on a untested project. As I said I am taking advantaged of some free time I have to start this how to. I have worked them out as proto units and have the PCB's ordered for them so it won't be long before they are finished and tested. These are DMX devices and I will not be making anything that doesn't use DMX unless it is not pratical to do "like the LedTriks". I know this knocks a lot of people out of using them but it would be no good to develop stuff that did not work for me.

In this how to I will explain what they are, how they work, and show you how to build the units. I will provide the PIC firmware hex files for the 18f1220 to anyone who wants it. I would like to finish the testing first. This is the parts list for the mechanics of Robo.

This is the stuff it takes to get the housing and mechanics working.

You will need the following tools:

*Drill & bits
*Jig Saw with metal cutting fine tooth blade
*A few screw drivers
*Something to measure accurately with (I prefer calibers but if you're careful a steel rule will work)
*A sharpie permanent marker with fine tip to mark with
*Allen key to fit the 4-40 bolt and wrench to fit the nut
