After an amazing time with our first entry into the UK championships I thought it would be a good idea to follow the crowd and catalog the development in the lead up to next years championships here on the forum.
Work has already begun on the next version of Conker and quite probably on another machine as well! With help from my dad we have decided to look into a new material for combat robots which will form the basis for both Conker II and his first machine.
Cellite is the material in question, this comes in various forms but the principal is an Aluminium honeycomb matrix with a layer of sheet material boned to each side. Various facing material such as Aluminium sheet, Plywood, GRP and CFRP are used. You can ask the company to face it with pretty much anything you like as long as it comes on a roll or as a sheet.
Back in my secondary school we used it to build our green-power car; some of you may be familiar with the event. Previous machines had been bolted aluminium box section and were not very light or stiff giving is load of problems. Cellite solved almost all all our problems instantly!
We have gone for the GRP or Cellite 620, same as the car, so that it is easy to bond sheets together with resin and more layers of Glass Fibre. The result should be a massive weight saving and an increase in structural rigidity...

I am using an identical electrical set up, the only thing to change is the pulley ratio on the disc, from 2.6 to 3.3. My dads machine will be built using the same technique but he is looking at a lifter rather than a spinner with the same armour set up.
Hopefully using this new material will be worth the investment, someone has to try it out, and then other can use it with confidence two and improve on our designs.
Comments, ideas and improvements most definitely welcome!
Edit: Forgot to mention... Solidworks say this weighs just under 10Kg, add a kg for bonding together the Cellite, nuts & bolts, wiring, relay, receiver, mixer and solder, another kg for the top 3 pannels, cellite boned to titanium, and I still have 1.6kg to play with? Wha...
