March 30/2000 - Build Update 6

Wow. March went by far too quickly. After doing some stuff with my car (namely swapping in a new engine and driving it home from Seattle), school work, and waiting for parts, I finally got to do some work on the robot this last week. In exciting news, Battlebots has announced that the June event will be the filming for the upcoming Battlebots weekly show, to be run on FOX, starting this fall. Crazy! More incentive to build a super-dope robot for sure. Less typing, more roboting! - Derek.

Suggested Listening During Late March Robot Building:
The Specials - Self Titled
Pulley - Esteem Driven Engine
Bracket - Novelty Forever
The frame with the mounted and modified cylinders. They had rods through the whole cylinder, which wasn't going to work for my application (my mistake in not reading a catalog careful enough). So, I just hacked one end off the rod, and capped the resultant hole. From initial testing, they seem to be working fine.
The newly welded in centre bars with the lower turret support. Also shown is the new 3rd pillow block for the centre axle. I also welded in some support underneath the winch.
As liquid CO2 will be used, I can take advantage of it requiring heat upon expansion. This copper tube will run between the regulator and the expansion chamber, in an attempt to get the CO2 warm and the intermittant duty motor cool.
Here's the expansion chamber, standard C&H stuff. The fittings are really nice though, not only do they look like rocket boosters, they are snap together and you can remove the hoses with no tools -- and without damaging them! Good to 250 psi etc etc.
A close up of the cylinder adaptor that will raise and lower the ground bar. Made from 1/8" steel angle and 1" tubing, I welded a 5/16-24 nut on the top to thread onto the cylinder rod.
A big, blue caster wheel. The steel sleeve inside was turned down from a 1.5" od .75" id piece of seamless steel tubing.
The upper turret mounting/battery support. Some sketchy welding, but most of it is 1/8" steel, so I hope it's not going anywhere. I'm not even close to the weight limit yet, so the 1/8" steel doesn't worry me (yet). With motor and batteries, but no legs or weapons the robot weighs in at 70lbs.
An over view of the robot at present. The caster wheel is a friction drive for the turret. Next up is finishing the new ground bars, mounting them to the pneumatics and getting the turret motor attached.
I found this page with the absolutley coolest old Japanese cars on it. So what if it's not robot related?.. Check it out here: http://www5.airnet.ne.jp/custom/ccf00/main.htm
