I still love the overhead concept and I still believe that they can be an awesome force if properly constructed. I'm just having major problems with that part. I'm starting a 2 year mechanical engineering course next week at collage so that should be able to, if nothing else teach me some nice useful practical skills and some nice bits of maths and physics.
Lack of planning and no real world experience with gears lead to the weapons failure. To combat this I've been planning the setup much more in-depth than before and will be leaving enough time to test that it works in reality. Here's hoping for >5rpm this time! General robot practice is to KISS, you know, Keep It Simple Stupid. That's all well and good if you want to build a
Parts for this are all major upgrades to the parts used on the V1.0 as I shall now compare.

Since having 6 separate motors for the wheels
I have wanted to play with a waterjet FOREVER and now I get the chance. Now people knowledgeable in such areas mentioned to me that all the cuts and blow outs (holes, etc) really ramp up the cost so I came up with.. Ze Great Uberlump. Its one long cut around the outside, and only 10 holes so its not totally bank busting allowing me to be able to afford a better material. I do have to put a bit more effort into assembly, popping the panels out airfix style and filing them down myself. Not quite the jigsaw puzzle some people like.. but then again this is just a boring box. That just about covers it for now, when I get my act together and start the build Massacre will feature quite prominently here.
