Dandelion Version 1 Build Report

This was a fairly complicated build, one of the most fun of all the Happy Robots.
 
Here's the frame.  The sides are 1/4 aluminum plate, and the bottom is 1/16 aluminum sheet.

The pieces are attached together with #6 screws; the side plates are edge-tapped for these screws, which is a delicate operation.

The boxes in the corners are part of the drive gearbox.

More progress, including weapon holder, batteries, power switch, and cooling fans.
The weapon disk.  Half brass and half aluminum with stainless steel teeth.  Only 3" across but designed to spin fast.  It has a 3/8 shaft which would turn out to be too small, as it bent during combat.
Gearbox assemblies.  The Promax motors have 4:1 gearboxes on them, and this is then put through another 2:1 stage.  So it's 8:1 to a 2" wheel, which gave me the speed I wanted but the motors were not quite strong enough, and I later burned them up in testing, after Steel Conflict.

 

Here the bot is essentially completed.  Note the belt drive connecting the front wheels to the rear wheels (1/4 wide XL belts).  Also note the Tekin Rebel speed controllers.
With the top on and the rear wedge attached, sitting on my work table.
Dandelion V1 had a pretty fancy paint job.
