lol i would have liked to hear what you thought of my bot alex lol

drum i could see it now you would have been like look all of these broken taps and how the holes dont line up at all lol

lol every ones rippin on the plastic im about to take a pic of the sides and show the damage i took on them

kv is a highspeed drumbot?

any pics of the drum and teeth? How did it do?

Any closeups of the drum?

Was it a 1 piece deal? I see a pair of teeth on one side and a round belt?

Any video?

Round belt in the middle of two rectangular teeth.
Yep one piece s7.

Single tooth or double?

Ok...so a standard non-staggered design

How did it do?

How fast did they spin it?

Did it fight any of the beaters and large drums?

frisco's up to some new tricks....

WOT, only vs other verts....

also try spinning the wrong way = someone's something is gonna break

vs wedges, etc. slow it down

Need to charge at wot....

Sting wmd vs Fluffy 2 = how it's supposed to work

need good driver, lots of practice and has to know what he's trying to do.....

Not always easy

We were running 5 cell on that so it was over 40K...

2.5 diameter solid S7 Non Staggered 4 tooth drum...

Designed to beat Plum and the other big high speed drums..

Did what we planned and performed very well but did not get real good bites...

Our UHMW was too low and we kept getting hung up (wouldnt let us test drive in the arena)

Steve was still getting used to controlling the weapon so he really did not slow it down enough to really hit anyone...

He is used to the bigger drums and needs a little more fight time with it before he can control it good.

He is a pretty good driver but getting hung up has its drawbacks....

I will say that we had absolutely no damage to this bot after prelims or finals....

Just some bad luck with a switch contact bar cracking on us as we turned it on in our first match (one hit done) then our armor draging the floor and preventing us from getting position on bots (actually made us get hit a few more times than normal)

I thought it was Steve screwing up driving but we found out the armor was hitting the floor causing him to stop then turn then stop then turn the other direction...

I think the only thing we are changing from this to next year is the front ramps....

What do you think Titanium or Stainless Front Ramps???

FRISCO

imo forget stainless...if y.ou have the eight for stainless, maybe hardened tool steel. make them pay for hitting you

a FULLY charged 5s (4.2v per cell) could see over 40k for a bit, initially? but probably not likely

laser tach

1.875 to 1.75 diameter weapon pulleys gives me the ratio to go over 40K..

We get 18.7 V out of the batteries for a bit. then drops to 16.8 at the end.

Math figures out

make your robot Nom Nom Nom proof

Def titanium or tool steel.
Everything else would give it a more solid piece to bite into and stainless is really bendy.

Ya Alex... I had a 1.75 pulley made at prelims but didnt use it and used a 1.125 pulley and then went a little bigger 1.875 at finals...

If you look, the belt was rubbing the top and bottom plastic and burning a groove in it because we went up a little in size...

After you guys hits us at prelims I thought we needed a little more then i found out that the ESC was not programmed right and after we reprogrammed it it was flying..

the one problem we are having is the o ring belt balooning up when we hit top speed.

I was a little worried about spinning backwards and not using any magnets to hold us down...

I would of hated to see us flying through the ceiling after spinning down.

The bot can take it and still run but A little worried there.

FRISCO

yah what he said lol i have been at school sorry i couldn't answer your questions and yes the video of the rumble was good if you want to check that out i think the link is on the swpa page somewhere ill have to look

You siad the plastic didnt have a scratch on it! haha
This is sort of what we we're talking about before and being inverted

not overly impressive

3 thoughts....outside of not having a spinning drum for most of the match (mlec'ish in that respect)

1) too many teeth ...would be twice as good or half as bad with single or staggered teeth

2) I hate the inverted op of most non-symetricals

3) damage to plastic severly limite by fact that other bot's drum dtopped spinning as well.

Any other video where it performed better?

https://youtu.be/LLbkFaIFfqs
kv is in this rumble and does pretty well

how is the weapon top speed half the match im surprised your battery didnt blow up

That is a good learning video

1) 6s 45c lipo pack = can dump alot of amps

2) rookie driver actually never let up on the drum (wot) until near the end...but he ws told to keep it spinning and avoid getting damaged by anything the horizontal (with MAG motor) could dish out.

3) finally gets a good bite and removes opponents weapon by slowing down the drum

4) This is a 40k+ drum, 6s with almost 1:1 ratio, but also this bot has a true single tooth drum.

Any of you guys playing with hs drums need to look at these types of videos and figure out how to setup what you have and how to drive/not drive a bot with this type of weapon. Look up in Riobotz....single tooth vs forward speed for bite, in section on drums and spinning weapons.

the video below shows how a hs small diameter drum can take out a much bigger drum (6 seconds into the fight, it's over). The drum needs to spin tho..and fast. Hard to find a bigger drm /beater than Fluffy...ymmv

oh believe me i saw the fluffy video along with all of the other sting and rattler videos on your youtube lol

?
But did you try to analyze it?

here's my take on KV in case your interested.

1) Take the drum and mill off 1/2 of each tooth..i.e, turn it into a staggered single tooth.

2) nix the O ring and get a decent belt on there and keep the ratio close to where it is now.

3) Practice full speed charging

4) Continue to improve inverted ops

5) Possibly clear a spot on your trophy shelf....hahaha ....

6) Tell Frisco to send picture of presidents...

Cody yes i have analyzed them many times i saw different driving styles and different weapon speeds for different size hits ( more bite/ less bite )

Rj

1) so you mean like stings drum and what will that change

2) ill think about it

3) do you mean running at them the second the match starts

4) yah need to work on that

5) will do lol

rjw's right if u make it so u machine one tooth on each side of the drm it will spin faster than it already does
