made up some aluminium strips thatll act as giant washers for where the actuator is going to bolt on. dont want that pulling through the base plate. and it makes it look more aluminium made.

also figured out a way to bolt the side panels to the wheel well walls. not sure how im going to bolt that assembly to the baseplate now though, might just use some more L bracket on that.

some of the wood is starting to split in the corners too, ill probably try coating all the edges in 5 minute epoxy and see if that helps matters. might try painting the entire MDF panel in it... who knows might make it a little better.

much design work done on the clamper mechanism today. and i also made one really cool visual change that really gives it that right look.



BUT the change is dual wheels. instead of just a single pair of red wheels it now has two sets bolted together side by side, reduces wear, gives it more traction and it makes the thing look seriously MEATY. not worried about the gearboxes as the whole robot will only weigh some 7kg when its done.

this is what the mech looks like after some extremely quick designing. havent done any accurate geometry positioning and stuff yet, its all just been thrown in. made out of 10mm aluminium and running on 16mm stainless steel shafts. that bit im making seriously hardcore because i want to use it in a newer feather down the track. and face it MDF would never be up to lifting 14kg over such a long arm.

have to lengthen out the forks and jaw too, made them much too small.

more design revision... said i was going to build a crusher from the start and wouldnt you know it here i am again...

in an appropriate action shot..



simpler, stronger, made from 6mm steel it weighs 1.5kg and its just gunna have a shyte load of power to it i should hope. the leverage on it should be pretty well as good as it gets because about 150mm travel on the jaws translates into 200mm movement on the actuator. 3mm steel wedge as well, was gunna use ali but im sure that would bend nice and quick like.

and i also took apart the actuator gearbox and found one plastic gear that was nicely stripped of all teeth, so ill have to give it an entire metal gearbox mod.

mmmm me thinks that a metal frame is starting to grow inside that robot ...lol

i was going to say i dont wanna be rude but yer that is starting to look more like a ali frame

hmmmmmmmm i thought it probly going to go this way.

the down side to this class is that many of our weapons need metal componatry to mount to or eles it will break under the force of its self.

just looking at the pictures of the above shot it looks like glens just using wooden armor on metal frame and mounting everything to the metal

Im not entirly sure bout the rules in this class but i hought a "wooden" bot could only be made out of wooden bits with a few ali or steel brakets in it to mount weapons on not to make bulk of the frame of it.

mayby im being to harsh but iwould have put it in the same weight class as the metal bots due to the fact that it had a metal "frame" in it

someone corect me if im wrong

No frames allowed; Means that the MDF is structural damaging the MDF will lead to a broken bot that can be easily repaired.
We are tying to avoid framed Bots (welded, bolted, glued, riveted) because we what to see robot disabled though damage and then rebuilt for the next heat.
You can us blocks, brackets, angels, etc of any material to joining of MDF panels

---

well with the brackets its just I think that they go all the way up hence unbreakable and they are also the same size or very close to the same size as the mdf armour. So if you break the mdf all the metal brackets will hold the rest of the bot. thats just what i think.

I think it is fine, the metal brakcets spread the load to the mdf. In the end the 'frame' is the mdf, the point is that if you hit it with something mdf will break and the bot will not hold together.

Glens Bot does this fine, break the mdf and the robot is a pile of brackets... hehe

looking nasty Glen! I like it!

well it does look goodbut i think we may have to draw up a clear ruleing system for metal braceing in a bot Ie something like 25 % of the weight can be used as a support structure


PS sorry for the clogging of the build thread we should continue this in the "fun bots" section.

oops sorry Glen the coment was meant only as a bit of humour .. at the moment you are starting the precident with the wooden class so it wil be up to the event organiser to determin whats brackets and whats a metal frame ... i cant see any of the angles bolted together so im gueseing your still with in the rules ..

hehe thats alright andrew, itll be interesting to see what ammendments have to be made when its all done, that MDF is some wierd stuff it is
