Red Wedding

Red wedding. It's fights should be short, brutal and ruin everything for everyone just like its namesake.

Ellis and I got these discs cut at the same time, he used his on Newton and I tried fruitlessly to use one in a vertical. Just slightly too big to get it to look right (derpy proportions etc) or be in the weight limit. Horiz it was then

Most of you know Newton as a phenomenal piece of workmanship and a wonderful testament to what can be achieved with skill on the builders part, hand tools, patience and lots of care taken over every detail to get it perfect.

This is very not that.

Characterless and careless, Red Wedding should come together fairly simply and *probably* make a half decent robot at the cost of having any soul. I decided I'd want something that works and goes together nicely for once : P

So far this is what happened

I tapped the holes myself at least lol.

How did you make the piece that forms the back and sides from one piece? Did you machine it yourself or was it done elsewhere?

Oh and we need stats! Voltage, RPM, Mass.. etc!

Its just dished out from a bit of 30mm plate. CNC Milled. I didn't fancy doing it myself added it on to the bulkheads order as an afterthought.

Disc is about 500g with all the pulleys and stuff. NFI on what the RPM but about 8000 Theoretical. I might end up dropping down to 3s to get the speed down.

Shaft shortened and threaded, disc mounted. Spins pretty freely and clearance is all good.

Did a little work on the top and base of RW. Cut out some carbon fibre to insert into the top panel. For a totally handmade part it fits pretty nicely.

Also I've been shopping. ESC's and motor ordered. Got some fingertech stuff from technobots would have liked to get some tinyescs but those will have to wait until funds are back. Got some foam wheels which I'll turn some alu or hdpe hubs for and a fingertech switch. NFI if the beetleweight EO's will let me use it but it was too nice not to buy one. Can always use it in an antweight or something maybe or a passive beetle if people are uncomfortable with weaponed beetles running with a fingertech switch.
I've ordered a few lengths of threaded bar from ranglebox. That is how I intend to hold these panels in and mount wheel guards and thing if needed. Got some of the M6 too to use for ease of internal mounting in my featherweight, Massacre.

Nice work Harry liking that CF panel especially, what are the dimensions of it? it looks tiny but that might just be that i'm too used to looking at Lynx seeing as it's roughly the size of a small moon.

150 wide, 182.5mm long and the disc is 180mm diameter

Yepp tiny then, Lynx is something stupid like 250mm x 250mm with a 350mm bar.

Where'd you get your carbon fibre from haz?

That's such a clever disk.

Carbon fibre came from ebay.

Thanks

Stuff turned up :)

Threaded bar. Super quick delivery. Really nice stuff, surprising how rigid it is. Looks to be super useful for generic fixing of panels and stuff. No complaints thus far. Lets see if I do once I've used it.

Fingertech switch (which I wasn't allowed to use in the end ho hum) This is tiny. Quid coin for scale. Would use on a passive beetle or an antweight if I can. Its such a little cutey.

Foam wheels arrived. Pretend-O- Bot shot of RW with Egg to give an idea of size.

Really impressed with how quickly this thing is coming together, looking really nice, what's the weight currently at?

1316g without pulley or wheels and something else I can't remember

Love the name. I'll call my next bot "Rains of Castamere" and together we will ruin everyone's wedding!

Did a bit o Red Wedding stuff.

Step 1: make small hole

Step 2: make it bigger

insert motor and boomdone.

Getting a guy to print some hubs for the wheels if they ain't strong enough I'll turn some. Progressing nicely

That looks sweet man, are the drive motors just a push fit or is there something else holding them in?

Gonna make up some steel parts that mount the motors by the faceplate. Cheers

Do you think I should call my bar spinner 'Live and Let Die Boat Chase', cos if you are going to ruin a wedding, ruin it in style... or is that going just a little to far?

Hi, just wondering, what are foam wheels like for grip and wear and stuff?

These fingertech ones are great for grip. Int used them so I can't comment on wear

Cheers Haz. I'm just thinking of alternatives to banebots ones as there's hardly any left at technobots. I think foam wheels will work nicely though.

Printed hubs happened. They ait. Not great. Probably going to turn some out of alu instead.

Bored out the other motor mount.

Then decided to have a quick wire up and see how the thing drives. Had to piss about with the mixer for ages to get it to behave. Stuff is very shoehorned in atm because lack of proper mountings.

It drove tho. Pretty nice although control is a bit clunky still. Mind you that might just be my own driving skill or lack thereof.

Then gave it a weigh, was surprised.

http://i.imgur.com/6td25lI.jpg

Kinda tempted to make it a proper beetle not one of our 1.5kg fatties. The armour is 8mm alu so there is weight to come out of there if needs be.

How are you going to stop the wires from touching the outrunner? There is almost no space in there!
And you may as well take it to 1.5kg given that is now the official weight limit.
Amazing machine regardless!

Will bend some 1mm polycarb into a guard to stop wires getting eaten. Will leave that until I get a pulley sorted.

Cheers.

Had a day off today so I relaxed by piddling around with some stuff on Red Wedding.

Grabbed some generic offcuts of some random steel, squared them up and then began shaping them into face mounts for the motors.

Mount 1 nearly finished next to a bit of steel it was made from.

Holes drilled and tapped in the frame. The hole for the motor was a pretty tight fit so it was pretty important for it all to line up right.

http://i.imgur.com/rpTduWg.jpg

eeeh. Close enough. It also got painted black because reasons.

http://i.imgur.com/J9w5TJH.jpg

Both mounts made + motors attached.

Mounts done.

Thread necromancy time.

I'm back baby. And brushless everything too.

Brushless drive? handles really nice if it is

You at any of the Kinematic events? looking forward to seeing this

Yeah brushless drive. Nah I'm not going to kinematic events
