1 lb drum bot!

sounds good, i dont know if you posted alrdy, or if someone else asked, but what is your frame material?

he dreams of 7075..

haha yeah it depends on what I can get my hands on lol.

OMG these motors are so SMALL!!



I'm going to alro metals and robotmarketplace on monday to pick up the rest of my non-mcmaster-carr stuff. I'm getting excited!

So, where are you gonna fight these things?

I'd be interested in building one

on builder's db there are two upcoming fairy/ant/beetleweight competitions in FL - one in bradenton at the hobby marketplace on July 11, and the other in Tampa (called BARF lol Bay Area Robot Fights) on June 20th. I'll be at both. My dad is also gonna build an antweight for these but he hasn't settled on a design yet...

what does the arena look like?

how big?

Is there a pit fo bots to be pushed into or out of bounds area?

I think my bristlebot could take your drum spinner.
It's weapon, THE POWER TO CLEAN!

for GCRS, http://www.robotmarketplace.com/products/GCRS.html

yeah donald's right.

it's got drop zones. I don't know much about barf, but LOOK!!

(it's on the robot marketplace GCRS page) and I'm the fat one eating popcorn lol. Standing next to my dad. Eddie's in the black shirt. cool!

lol

I'm really pissed now because I'm out of town for BOTH competitions!! NOT FAIR!!!!! ARGHH!!

WILL!! good timing...
lol

I stopped at robot marketplace yesterday to pick up more parts for this! yay!



I bought a Spektrum DX5e, a Spektrum AR6100 receiver, a battery (Common Sense R/C 800mAh 2S LiPo), and two 56:1 micro gearmotors. OMG the gearmotors are SO SMALL!

I made two of the mounting brackets for the drive motors, and I got one of the two support blocks down to the right size. I need to cut slots in both, and put in two #4-40 tapped holes. I think I need to revise the design of the support system slightly because I expected a step between the motor and the gearbox, but the gearbox is flush with the motor, so there is nothing in my design to keep the motor from twisting. I need to deepen the U-channel I made so that the sides of the cap piece come down beyond the motor and notch with the support block.



I'm going to get the aluminum for the frame and maybe even steel for the drum later this week. I need to finish this bot in two and a half weeks!

Are AR receivers allowed in rfl rules???

I just ordered 2 BR 6000's

We may see you there in July with a 3 pounder and maybe a 1 as well

Looks good so far!!!

the difference is that the BR has a failsafe on ALL channels, whereas the AR has just the throttle failsafed. I think only botsIQ and the larger weight classes require the BR6000... I hope I'm right.

I know the differences....but you were just at rmp....and they are holding a competition?

I relaize that the insect classes are probably extreme budget tweaking classes, but a runaway spinner or drum could be dangerous.

yeah rmp is having a competition. the girl i talked to (amanda) said that she was excited for what I was building. I asked steve (the guy normally behind the counter) if I was allowed to use the AR instead of BR, and he said I was. I looked at Jim Smentowski's micro Nightmare and he used some funky receiver I'd never seen/heard of that steve said they no longer sold or something...

I'm sure at that level, they allow fm and maybe even toy tranmitter/receivers......just good to know.

btw: are you happy with the place that you bought your feigao's from?...was it bphobbies?

it was bphobbies. I ordered, and they came in like 5 days. No issues. Everything was fine, no problems. I've never had a problem ordering anything from anywhere though... I just ordered the fingertech tinyESCs today, so we'll see what happens there - they're canadian lol. the shipping was a little weird because it gave options, and three options were 212 days, and one was 13, and like two were 20, so I'm hoping 212 means 2 TO 12... if not then I'm totally screwed for this summer...

I'm looking at the sabretooths????? from rmp for a couple of possible beetles that may show up in Tampa and at rmp..we plan on using bb 24mm boxes with better motors, so 5 to 10 amps is what we need.

sabertooths are awesome! The 5A one was just too big to fit in my bot. We've used the 10A ones in our 15lbers with much success... you can't beat their features. mixing, inverting, etc...

would you say they are as good or better as a scorpion???

actually, I've never used scorpions, so I don't know... for us it was always "the sabertooth looks like the best, let's use it"

well. All my plastic parts are done.


my zip-tie support method for my drive motors may need some hot-glue augmentation or something... the motor is only restricted in 2 dimensions, not 3. again, I was banking on the fact that the motors would have a step in them which they don't... :/

i am so mad! I screwed up the other one of these...


there's like three hours of machining in each of these, and i measured WRONG damnit.
guhh. anywaysss these are the front shaft clamp blocks. 7075-T6. 1.275 x .5 x .5

a good piece of material gone to waste?

We use mastercam and solidworks and cnc most stuff....if it can't assemble in sw, then we don't cut it.

12 days till barf and we have 2 bots that we are waiting on parts for BEFORE we cut anything...hope we make it

the sabretooths arrived and weigh 45 grams each, not 32 as advertised at rmp!!!

That'swhy we don't cut anything until ALL the components are in hand, measured and weighed.

13 grams is a lot in a little bot....lol
