Melty ant

I have a few ideas for a melty ant....and I have almost everything I need to build it, except for escs which are on the way.

Current design is cut out of a solid chuck of alu and has only 12 screws in total !! and 6 of them hold the top cover on.

Still so tough to make weight at 1 lousy little pound!!!

Should be able to cut and build the entire thing in a day...stay tuned...still messing with minor stuff, before going to the machines.

oh...and this will also be brushless

hmmm.
I was under the impression that meltys required microprocessors, gyroscopes and/or accelerometers, too much electronics to be feasible under 3 pounds!

Let me know how it goes (and how you do it!!)

Good luck.

motors and speed controllers obviously change, but the board, accelerometer and leds could all be the same from a fairy to a 15 pounder. Beyond that, just the leds would change....

Think of the melty electronics part (outside of the leds and resistors) as a receiver. you can use a br6000 in any weight robot, no?

What I mean is: "Isn't all that stuff kinda heavy and space-consuming?


I really don't know what I'm talking about, do I?

The whole thing is smaller than a scorpion xl and weighs the same or less

ShamWOW! i wish i had the machines you do, i have so many designs i haven't touched yet just because i know how much time and work needs to go into them. but then again i do enjoy the challenge of manual machining, any way looking freaken awesome, so are you going to send this one all over the place?

wow

roughly how big is it?


is it small enough to spin ontop of the larger one while it is spinning?(really cool video idea!)

Shamthanks...

It's a little marvel of engineering (I think)

The body is cut from a single piece of 1" x 6" 6061 alu...Yes...1 solid piece!!!

When you see inside, it's really a clean build

I took a 1 5/8" Colson and cut it in half.... wheels are 5/16" wide, but they need to be flattened out (broken in)

Wheels are belt driven from small Neu brushless motors (discontinued razors that I bought for a song)..

The bot measures roughly 6" x 5" x 1" high. The swing of the knocker is roughly a 7" diameter and should get up to 4500 or 5k rpm. It seems weak compared to the beatle, but it does hit very hard...

Both melty's have dual leds, and the gear switch makes driving upside down painless. I'm still messing with the code, but it should be ready by Saturday. I did run it, but my Ar500 went south???

Darn. You have to make every competition hard for me dont ya?

Which direction do you spin? If we are going for a weapon hit, Lets at least make this a spectacular one.

It spins sideways....

I'm also bringing Sting to play with Cake...so we should have all sorts of fun

i think he means clock wise or counter clock wise, because i think DDT spins clock wise if im not mistaken. and somebody better get video!!! witch reminds me, didnt you but a high speed camera rj?

I'm messin with him....at the moment it spins clockwise....but things can change... eventually it will spin either way as needed.

Yes I have the hs cam, but I want realtime vid and slow mo if possible, but not enough hands unless I can get some help...

ya i know what you mean =P im going to make a camera mount for my tripod so i can have both my hs and normal cam on it at the same time because im sad that i didnt get some of my fights in real time from the bot blast

I know...you really need both...the slo mo is really only to get a better idea of what happened at certain times during a match, which you can see by going frame by frame with standard video, except that you can miss stuff.

Clockwise it is! This will spectacular!

I am amazed how small that bot is. You spoke about not building an ant because everything is so small and light, but here you are with this compact marvel of engineering! Your robot fits inside DDT's blade! XD

with Cody's chewy aluminum, if it stops spinning, it'll get crunched totally!!

Outside of testing melty boards and code,etc. I want to see how the 2 totally similar yet deifferent designs fare in battle.

Mind you, the arena will probably claim both ofnthem, cause they have a tendency to ping pong..

DDT has a Ti blade?? my knocker is also Ti...

How fast do you spin that thing?

All I remember is serious gyro and a bit of ping pong as well...but the blade did look huge!!!

yup, also Ti. 6.5" @ ~7200 rpms.

rj, that ant is gorgeous

hey you know the next NERC event at the Franklin Institute will be in a 16x16 ants and up

the ant could do well on the wood floor, but not sure about the beatle...

First test video...top speed of 5500 rpm so far

Inside the little tort

pretty neat little design, very cool, hope is does well!
