And so they don't get hit up and get hit by the bar :P. Looking great Haz, looking forward to seeing it!

[harry hills]

^ That too. And Cheers.

Hi Harry,

When I was running a Hazard style bot, I developed an alternative hinge that worked really well:

Its just a row of bolts along the edge of the armour that have a gap under the heads. by adjusting the gap under the heads, you can get the right amount of motion so that the armour rides over the floor seams but opponents can't get underneath. you will also need to make the mounting holes in the armour a bit over-sized.

In my case, two M8 cap head screws at either end of the armour plate worked for years.

Sweet idea Nick. I have been reading that 350 odd page thread of yours lately. Great stuff. I'll see what I can do wedge wise. I got a few 12.9 m8 capheads so they should hold.

You can see what I did on the very first photo on page one .

Just rewatched the melee from last year. With any luck Binky wont be able to peel back the front blade of this version like tin foil. It will be a proper fight! We aught to have an all spinner Annihilator! It would be chaos!

Never looks like I'm making much progress (side effect of Pretend-O-Boting)

I sneakily machined the main weapon shaft at college the other day. I mean what else am I supposed to be doing, work or something? Idk. Got it to within 0.01 of 25mm so it should be fine. Fits the bearings nice. Also mounted the weapon gearbox and motor now.
Don't worry I will be making sure that the wiring is as far away from the spinning everything as possible. I'll hold off that until I have found a sensible wiring loom that makes sense and isn't too spaghetti.

Coming along nicely Haz. Robots always look better on grass too.

Where have you decided on placing the link?

[harry hills]

If you look you can see the shaft is hollow. Link will be above the bar Little spinner style. I'll be milling out a protective case/box for it though. Its the safest way to do it, although not the most practical for the robot. And thank you

Hi All,
Did some more on the battery mounting, added a bracket and some foam to protect it from shocks.




Also got the lid cut out and the hole for the pulley/bar to go through cut. The pulley is sitting about 4mm lower than it would normally because I just stuck it on there to show how it fitted through.



Bar got a coat of black paint, but the edges are kept bare, thanks to daveimi (I think) for the suggestion.




Still got lots to do. Hope it comes together ok. Cheers.
