Featherweight Database

[tough_as_nails]

Well i started designing again on my featherweight. It will be a 1T hydraulic crusher. The jaw was already made 2-3 years ago, so i have to base the design on it.

Heres a picture from the first scetch.

The robot will be called Firestarter, as i havent found another robot yet with that name.

i think poly carb will be better as it is stiffer, i think 6mm will be fine but i dont have any axe robots so may be wrong

for an axe robot you need the base as stiff as possible. I would make a metal frame and put that on a polycarb base.

prodigys evil twin (pic on profile)

my daughters first robot and also the first fw i have built and completed from scratch myself (FINISHED AN HOUR AGO!), doesnt look much but pretty chuffed. yes i know its a wedge but i wanted something for her that would be reliable and stand up 2 spinners. its similar to prodigy except its smaller, and alot stronger!!!

she has called it Kahn, after a dalek from doctor who apparantly? it has 6mm mild steel wedge, 15mm poly side armour over 2mm steel, 10mm poly lid. running on 18v drills, weights 11kg. its first outing is Dec 29th at think tank, so she has 3 months to learn to drive it.

i cant believe my 8 year old daughter has a nicer fw than me, and better controllers! something wrong somewhere

we should be able to pick our own

most teams have atleast 2 robots? not sure

but i no big nipper team do and we will have beauty 2 and beauty 3 by then and it wouldnt be fair if we would only be able to fight with 1 in a tag team comp

could be called the tag team championship :P and hold an event once a yr

Id stay away from polycard base if possible as Little hitters first armour was 6mm Polycarb and the first test fire of the axe shattared it. The base is Nylon (I think) and is 8mm thick in the middle and ~25mm on the edges to srew the amour on. As for the Axe head it all depends on the power of the axe, but 6mm doesnt seem enough.

Go for an ali base. If i have done my in my head sums correctly then you should be able to get a 4 or 5mm ali base in the same weight as a 10mm polycarb one.

Instead of a flat plate why not use a solid bar ground down to a tip at the front?

Kahn looks great Adrian. I hope you daughter enjoys it.

BonX has used a 6 mm polycarb base for 1,5 years, it finally cracked during RoboGames during this match,

Orange dave is the improvement to red dave. It has four wheel drive and has lifting prongs on the front. It was not quite finished at hemel but I have now put the hardox on it.
It has good armour and stood up to little hitter well.
It has suffered from a few issues though. Weapon siezed up and stoped working. Ni-cad packs are a bit rubbish. One of the speed controllers only worked in one direction. Soon to be inproved with new weapon, batts and speedo.
