Forgot to mention, of the layering epoxies, the more of a pain it is to work with the better.
You get some that need baking. Others room temp. Guarantee that the one you'd ideally like is impossible to do without special kit. Which is why I'm more likely to save-up and get a firm to do it for me :(
Right, have finally got some proper figures for my proposed X-bow style actuated "captive bolt" or spear type weapon.
A collector I've been able to reasearch has a hand-held arbalest which weighs 18lb and has a draw-weight of 1200lb (5,200N)
There were larger and heavier ones that went up to x 5 this power for use from ramparts.
These were using spring-steel whereas we have carbon fibre, and the weight includes a large stock which I will not require at all. We also now have the reverse-energy configuration and compound-bow technology.
I am confident that I can seriously hurt an opponent bot with this arrangement, and possibly the first move should be a simple FW (not a walker) with this kind of weapon on-board for testing. I need to know how effective it is before designing the rest of a HW walker, because the entire bot will need to work around the size, shape and weight of the weapon.
It WON'T be top-mounted though, it'll need to be housed within the body somehow. "Reverse-energy" type arrangement will help make this possible, but it's still a concern.
My plan for my hw is to have a high pressure pneumatic ram with a spike on the end, it should make 1000kg of force which I'm hoping will be enough.
I know a lot of people have advised against weapons like this in the past but I hope it will be able to do something and at least it is not another flipper!!
I would gladly take a shot gun to any of my machines. A tethered projectile weapon will do little damage
No wonder: a shotgun is unlikely to deliver much more than 3500 fp. Far less than what I am now proposing.Quote:

You store energy up in a spinning fly-weight and release it upon contact using a spear-tip or "tooth"
I'm planning to store energy using modern materials used as springs (steel won't do the job, it's too heavy and sluggish) and release it upon contact using a spear-tip.
It all comes down to how much energy you can store.
It's not been tried before as far as I can tell, but the figures stack-up. So I'll trial it and if it doesn't do the job I'll move to plans B and C.
At the worst, I'll turn it into a straight crossbow without using it in a robot at all.
sorry but i can't really see this being an effective weapon, all it will do is push the 2 robots away from each other or at best a small dent in thin metal
even with some of the heavyweights on robot wars they either made a small hole in thin armour or pushed the robots away from each other and they had 100kg of weight absorbing the force where as feather have such a small amount of weight and less grip on the floor
this is assuming i have it correct and your building a feather
Plargen, I will most likely be building a series of very standard almost off-the-peg feathers on which to test certain concepts, but corvis is eventually to be a heavy. I will have 200k to play with.
If you have the technical ability to create it that's great. Its really good to see some different designs and thinking outside the box. As an event organiser, if you could send some technical drawings of how the projectile will be tethered and the mass of the object being fired we can make sure it is safe to contain in the arenas. It may well be if its anywhere near as effective as you suggest, and you seem to know what your talking about, we may want to arrange some testing of your machine at our workshop to be sure it's safe to contain inside the arenas
Lemme build the damn thing first!Quote:

the 200kg version sounds like it could have potential
