Re: Team Terminal Damage

Thanks guys

Alex - the boxy part of the chassis is 75mm high (and I'm planning on tapering the back now the same was Kaizer was, if I can get away with even less internal space - its gonna be tight!) and the height at the front skids will be about 130mm when I get the additional skid pads fitted in place.

Calum - I'd never really considered WD-40 to be the best lubricant for cutting stuff, I always thought a more liquid-like fluid was needed, and I also didn't know if the WD-40 would have any weakening or corroding effects on plastic but it seem fine, and I'll need to stock up on a couple more cans soon. Hoping to get the videos uploaded for you today as well for the old weapons setup; yesterday's time managed to disappear a lot faster than I anticipated :|

Re: Team Terminal Damage

ok thanks that would be great

Re: Team Terminal Damage

Guys don't bother with the WD40 as its quite pricey and a waste of good lubricant!

Instead just buy a litre of coolant here http://www.chronos.ltd.uk/acatalog/Chro ... c_124.html

The 1 Litre Multicut Soluble Oil is brilliant for all cutting operations. Just take a sports cap lucazade bottle, pour a shot of the oil in and then fill up with water. I use this with my lathes and have no problem and that litre will last you a LONG time if you dilute it correctly, believe me!

You do have to spend a min of 10 quid with chronos but I'm pretty sure you could find some other random tool that you never even considered using before for a couple quid.

Re: Team Terminal Damage

O and the new chassis looks good Jamie

Re: Team Terminal Damage

Update

Well I didn't get it driving today; it was one of those days where you think everything will be nice and simple, screw a few screws in, bolt/tape some things down, wire up some connections and it'll all be good but instead it turns into one of those days where little niggling things slow you down, get in the way and generally just annoy the crap out of you.

The rear of the robot got cut to a taper because otherwise the wheels would not touch the ground, and tapering it shortened the length of the base and solved that problem. But its very tight for space inside now (tighter even than my dad when it comes to paying for shopping/restaurant bills etc )
I always prefer to build my robots to contain as much power as possible in as small a space as possible, but I'm pushing it a bit this time:



May not look too squished but by the time I add a second battery pack (to go in the void on the right-hand side) motor mount, Victor speedo mount, wires, radio gear, removeable link, LED, aerial etc it'll be difficult to work with. So I'm going to really have to keep wires trimmed and everything neat and tidy if I don't want to drive myself nuts at events trying to effect repairs. It'll be a bit better when the brushless is fitted, but since the bigger motor/speedo combo of the Speed 900 is my back-up and space is limited, I figured it'd be better to mount that in place first to make sure it fits and then swap in the smaller brushless setup. Should be plenty of room inside once I've indulged in some A123s, Scorpion or Sabretooth controller etc

Gonna take a building break for a few days after today frustrated me quite a bit (part of me wants to chuck the current chassis, remake it from Nylon and stick to the original CAD layout) and such a break coincides nicely with going back up to Glasgow for the weekend to work

Re: Team Terminal Damage

looking nice but very tight on space. whats the over all dimensions? im also interested to see what you will do with the wheels to protect them once its finished. lol i know you feel like giving up but just think- no self-righting hoops

how heavy is it so far ?

and thanks gary for the link ill get some of that

DERUBOLL IS LOOGNKI GOD WARGHG

GO PENGUNIS

[RogueTwoRobots]

Re: Team Terminal Damage

Well a night's sleep works wonders for the perspective; I'm not quite so annoyed with it now and reckon I can cope with the challenge of getting it fitted/wired up in such a small space
And yes Calum, remembering that I wouldn't need self-righting hoops helped :P

Current weight as it is in the picture is 4.6kg; when I add the drum and shaft onto that it takes it up to 9.1kg - then add another 500g for a battery pack gives me 4kg free for armour! :twisted:
More when the brushless is fitted

Wheel protection will either consist of some 12mm polypro, or 12mm HDPE, or possibly some bent steel/welded ti. Other option is to look at Hornet, which has been running five events without wheel protection and has never lost a wheel. Kaizer's wheels were exposed though for a couple of battles at the UK champs and took some damage but still not enough to rip them off the drill shafts. But they'll be one of the last things I'll consider.

Kody, go on, have another

[typhoon_driver]

Re: Team Terminal Damage

Make that 6 events for hornet so far! :P

Having your wheels exposed with a spinner is quite a good idea as people always focus on them and never think to worry about the big spinning mass in the front

You'll be gaining more weight if you go to A123s too mind! Might as well just make it into a hardox box with the spare weight.

[RogueTwoRobots]

Re: Team Terminal Damage

I've been considering swapping the poly for hardox actually since the spare weight is there for it. I'll wait and see what the weight of it is all in when its completed; this chassis will probably run at the tag champs though and then I'll look at possibly making it hardox

Eurochamps 2007
Tag champs 2007
UK Champs 2008
Rebel Robots 2009
UK Champs 2009

I still make it five events
When else has Hornet been out to play?
(yes I sadly have a memory that seems to subconciously note unnecessary robot stats such as this)

[typhoon_driver]

Re: Team Terminal Damage

meh there was another one in there somewhere. Every battery pack thats gone in the robot so far has lasted the grand sum of 2 events, throw 3 batteries in, you get 6 events :P

Either way my wallet and bank balance have felt the number heavily. I doubt there is another feather out there that has actually required a full rebuild to the same degree after each event

[RogueTwoRobots]

Re: Team Terminal Damage

Hehe fair enough
Yeah like you said one time, you should really be on Hornet 6 or Hornet 7 by now
Probably the machine that's had the most TLC in the featherweights!

Update
Nothing major, but will be swapping the polypro that I'm using for the base panel right now for some aluminium, since its easier to bend and mount at the points where the chassis blukhead slopes. I searched on eBay for some ali and the very first item that came up was the perfect width and only requires 20mm trimmed off the length

[typhoon_driver]

Re: Team Terminal Damage

If I'm not wrist deep and sweating trying to fix hornet its usually been retired from the event :P

Gotta love ebay!

Re: Team Terminal Damage

Well this build thread has been stupidly quiet for a while. Sadly not got any robot build progress to report but I was bored today and trawled through a bunch of old robot pictures and footage on my computer. Came across this from four years ago; ah the good old days of windscreen wiper motors, SLAs and microswitches

http://www.youtube.com/watch?v=8nNw1HP06FQ

Exams finish next Tuesday so after that I'll be able to get back to robot work and start preparing everything for the tag champs. Drumroll II is on hold construction-wise at the moment due to me not being happy with the chassis construction and design, so the original Drumroll will be in action again. To-do list includes; making a new cross-bulkhead to replace the cracked one, soldering up some new battery packs out of existing pile of Nimh cells, fitting the brushless motor and controller, painting the drum and (all being well weight-wise) incorporating a srimech arm in a bid to get rid of the ghastly roll-hoops.

Then there's Incisor to build from scratch (CAD started today) and a power tool drag racer to make and pimp, as well as sorting out all the stuff for camping. And by the time I get back home, I'll have a grand total of two weeks - eeep!!!

I'm looking forward to seeing how I get on with this actually. I was planning on having nice new A123s in Drumroll and a well-constructed Incisor etc but the Subway shop I was working in has recently shut down therefore my plan of working lots of extra shifts to raise bot capital has fallen flat on its face. Factoring in camping supply costs and fuel, its not possible to get A123s, appropriate charging gear and loads of bits I don't really need. So modifications to Drumroll and construction of Incisor will involve a fair bit of old-school style 'make do with what's at hand/what can be salvaged from other people's trash'. It'll involve a bit of bodging which means some materials and parts won't be top notch but I'm really quite looking forward to seeing what I can do by returning to the 'use stuff I've already got' approach rather than the 'new stuff bought off internet' process that I've been using for the past two years.

I think I'm starting to slip into 3.30am waddling mode so I'll retreat to bed now
