About Bodacious Hillar Wolt

My son's plastic 1lb robot is called Bodacious Hillar Wolt, a name randomly generated by Tinkercad, the 3d CAD tool we used to create it. We built BHW to fight in the monthly Robot Roundabout events that ran regularly over 2016 and 2017.  These fights were among the first "plastic class" antweight fights anywhere, but it was and is a good idea and folks seem to be doing it all over now (smug face.)

Bodacious Hillar Wolt , much as it was when it first fought in 2016.

Since the fights were a new class, what would work was largely up in the air.  All the robots were brand new robots.  (Sadly all my photos from this early period were lost.)  Mistakes were made at first, but the robots evolved and improved rapidly, as did the building skills of everyone who participated.

The 2nd generation. We went through a bunch of these.

The first upgrades included stretching the body out, widening everything, including the weapon. The wheel guards were added to both protect the wheel and keep them from falling off. Sturdier screwed on "wedgelets" replaced the fragile oval feet keeping the spinning weapon off the floor. We got it dialed in and it got better and better. Until...

After the rumble. A nice view of the weapon motor and pulley, though.

While it obviously did well, I could still see one or two places spots for improvement. Subtle, to the untrained eye, I know.

The new and current version of BHD was the most radical upgrade since the first upgrade, all those years ago.  While keeping the basic dimensions the same (I used the original CAD, of course) the rear wedge was removed and the wheelguards and weapon brackets heavily reinforced. 

And how did "Old Bo", the reprint of the original do?

It was worse than this makes it look.

Old Bo needed upgrades all those years ago. It was front heavy, the wedge was too low, and it frequently couldn't move. This time around it broke or got stuck too quickly for the wheels to fall off, but they would have. The notion that I could/should improve it keeps popping into my head, but I can't because already have.

 The Black/Blue Bodacious fought with the old green one, and did well, only taking minor damage. It got pitted by Mission Control in the quarter finals. More on that later.
