bonecrusher- the first bw from Suvv Industries Robotics devision

meet wonky i cobbled together in 2 days out of offcuts of hdpe and polly i had kicking about in the scrap pile gona get a nice peice of titanium to make a blade for hte front and then watch it get dismantled by the first spinner it fights the second pic is an attempt to show ware the esc decided to eject lots of smoke but i dont think it came out to well on cam

and im only guessing at the short it was smoking like it was about to explode

I use these for testing, the plastic can be be slid on and off the clamps.
But they should only be used if the machine stays stationairy.

been a while since i have done anything to this so i thought id bring everyone up to speed

since i last played with anything work descended on my life like the proverbial ton of bricks and i lost a bit of time i then suddenly i had entered a competition and had nothing to fight with so i panicky turned to harry and with his help..and me throwing money at him till i was poor the creature you see in the picture below was created amazingly it all came in weight even with 4 mm steel wedge and bumpers

Attachment 5496



iron games scotland:

being my first competition i was decidedly unsure how it was going to go but thankfully everyone was accepting of my nervousness the night before after a simple rewiring screw up i fried the entire wiring set up thankfully the link melted before any damage was done but it did mean that i was going into my first competition having never even tested the thing they let me chuck it in the box for a bit between pay to play fights and i discovered 2 very important things 1. allways check you have tightened the grub screws on your hubs 2. it doesn't handle like anything i have ever driven before...great but i was positive my wedge of doom was ready for anything......

fight 1 eggbeater:

i was nervous and i was drawn against the one bot i was worried about at the comp simply because it was a vertical spinner that i was convinced was going to rip my front wedge clean off thankfully he was having as many issues as i was he couldn't spin up and drive at the same time or at least not very well so my plan was to avoid the front and shove him side on and pit him activate calls out and i charge...and immediately turn left i take it a bit more gentle this time and get proper forward movement however i drive straight into the nasty spinning bar of unpleasantness amazingly the front stays solid on the bot and it does a double back flip and carry's on moving then his bar stops moving so i figure this is my chance i charge in and wedge myself in under the blade stopping hit from spinning however as i try to push him i find myself going backwards making a nasty grinding noise which turned out to be the hubs that had come loose from the motor shafts after some more pushing and some more back flips cease was called and egg beater got it on a judges decision i felt better knowing i could take a pounding but i definitely need to sharpen the wedge so that it gets under people.

fight 2 flatulance:

having tightened the grub screws i was determined to do better however my next fight was against flatulence who after much dancing between us both lifted me up and beached me on my rear bumper the fight was pretty uneventful and once again i had the wonderful noise of hubs spinning on wheels meaning i have no pushing power at all

fight 3 fqhwaghds:

this was more of a dignity saver attempt for me having won nothing so far and surely i couldn't lose to a bunch of cable ties and optimism...oh how wrong was i things started off well i was able to push him about and generally do something i opened the pit thinking i could navigate him round and in my haste to get back into the fight i forgot what my bot does if you give it full throttle...and turned myself directly into the pit

overall it was a good competition and i learnt a great deal including the wonders of loctite and that i need to practice driving this thing watch this space as i will hopefully have the designs up for the mk3 and who knows it might do better than all loses.

You did really well :) Something that may help like it did me was replace the grub screws with normal screws of the same thread. Then I really managed to tighten them. N as you said threadlock. What electrics does your bot run? Would it be ok to see a pic of the inside?

its 2 40amp botbitz controlers and in my haste to glue the grub screws i may have loctite the entire hub to the motor shaft....it may need combat to shift them off the motors again and i have discovered that the grub screws have fell apart inside so they werent tightening properly once the whole glue thing has decintergrated im goong to drill them out and re tap the threada d try your suggestion

Secondary weapon: intimidation and mind control. YOU CAN'T BEAT THE FHQWHGADS.

In all seriousness though, I'd consider that a win by all accounts, you walked all over Fhqwhgads. Was extremely unfortunate you ran into the pit! And, you managed to bust one of my gearboxes further, I'd need to watch the video back of it (anyone have that btw?) but I was immobile on one side I think. Ironically if you'd have left me alone, you'd have taken that!

Great machine though, if you can get the little issues sorted out I can definitely see that being a tough little machine! How much weight did you have left over for improvements?

i think i have about 15 grams spare and in traditional robot form now that the competition is over i have got it working much better im going to try to put a bit of a better edge on the wedge and see how it goes and annoyingly my camera decided to not record that one as id like to see the replay on it myself

Unless Fhqwhgads gets hoisted by a certain servo lifter robot, dragged around the arena and dumped in the pit ;)

I think I got all the fights on video so should have Bonecrusher v Fhqwhgads (I'm finally getting the spelling right without having to look at it!) but haven't sorted through my stuff yet. Will get it uploaded if I do.

Which simultaneously broke my gearbox, yes I know ;)

And that'd be awesome if you could do, the crowd reaction was utterly hilarious haha. If you have the aftershow things-running-into-spinners match as well, get that uploaded because that was rather brilliant too!

i beleve the crowd reaction was cheerio cheerio cheerio a tradition scottish farewell for when you have truly faceplanted the pavement of life

and i have the spinners match will get it up at somepoint

The one part of the Event that Lynx actually did something useful, was great meeting you and the robot looked really good for a first effort. Just remember, you didn't do as badly as me :oops:

thanks was great putting names to faces at this though i did work out why my robot seized up at the end i might have been too optimistic witht the loctite and glued the motor solid

well i thought i would drop in a little update seing as my last post was just after the scotland event
that event was a great learning experiance for me in tearms of driving and wheel atachment and how not to use loctight for the mk 3 i decicded to stick with 2wd after much procrastinating and waiting of parts from hong kong i decided sod it and looked at the flaws with the mk 2.

i sat and watched my fights and decided that i needed to

improve the drive train

slightky thinner wedge as 4mm was overkill

stop it being able to sit on its back end

after discovering things online and watchig more of other people robots i did some cutting and grinding and swareing and i think you will filnd the bot mostly an upgrade it now has much grippyer wheels that are attached witn double grub screws so it should be solid the base and top panels are going to be recut to fit better and will be made out of 2mm hdpe the side is 15 mm hdpe and the front is a 3 mm steel wedge that hase been grinded down to give better contact with the floor hopefully it will survive the big hits and with its new drive train it will be able to shove most things out of the way also did i mention its goong to be running on 14.8 volts so to quote the book of clarkson poowweeeerrrrrr

well folks its the long overdue update with what happened at the champs and plans for new creations and the next iteration of bone-crusher.

the uk beetleweight champs 2015

i rocked up to the champs with with a large degree of optimism and after getting everything plugged in and putting it in the arena for a test i discovered a major issue, the wonderful wheels i had basicly designed the whole bot around for max pushing power had absolutely zero traction on the arena surface i had to have them going at full speed just to get a hint of movement que panic and the bodging of some snap wheels to a a spare set of hubs i had with some hot glue suffice to say they were wonky as a clown car but no time left before the first fight meant i had to dive in to it.

bonecrusher mk 3 v bananageddon v rpm v incomplete control

well with wonky wheels i ploughed in with little ability to push against a very good spinner and Rory's one night superbuild and the beetle cluster that did much better than everyone expected i tried pushing incomplete control for a bit then got lucky and managed to shove one of the cluster into the pit with the other half decided suicided into the pit not much else happened as time was called and somehow i went through on a judges decision

bonecrusher mk 3 v limpet v incomplete control

this match had very little highlights in between fights i had tried to mcguyver some wheels useing gorilla tape and hot glue and it turned out to be utterly pointless as after much pushing and shoving limpet decided to end my champs run and dumped me in the pit

the future
boncrusher mk 4
first plans for this are better drive and traction thankfully someone was very generous and gave me some banebot wheels 4 to be precise so its going to be a 4wd upgrade with lots of grip and hopefully will lead to something more effective

scorpinok
one of 2 new bots comming this year very much an attempt at getting a spinner further in the uk champs than this year again updates comming soon

sweet dreams
this is more of a show bot than anything else basicly a beetle version of nightmare more info to follow once i have more to tell
