Dual weapon ant build diary

[Roboteernat]

Hi all,
wanted to introduce my idea for a 2 weaponed ant.
It is going to be a challenge with my plans due to the weight, but i think its a challenge worth taking on! who knows what the results will be like,
Anyway, this is a new bot that adds to my DELLapidated bANTtry and my disk wedge bot, which have not actually been to a battle...
Dell was an initial tester push 4WD bot, and Disk was my first 3d printed chasis bot.

This new bot will have a tube spinner and a flipper in one compact unit.
My current parts i have been buying will allow me to have a nice 3d printed chasis with 0.3mm titanium armour. The sides will be of 4mm CF.

Here is a nice (somewhat not completed) solidworks model of the bot. currently i am happy with the weights, once i have added weight reducing holes in the tube and cut off the excess from the servo.

So far i have machined the tube up and started to machine my CF plates for the sides, although i need to finish the chasis before i can settle on the CF sides.
Will have a nice clear PC top` too to see the goodies.
I am waiting for the final part to come, my Lemon RX from the US before i have all parts to finish off a nice design.

Specs: (to confirm when gone to my stock, will add links soon - most from hobbyking)
Weapon: Flipper and spinning tube
Drive: NanoTwo controller with 2 gear motors (speed unknown as lost the spec sheet!)
Battery: Nano 180mAh 2S
Flipper: Servo 9g
Tube motor Turnigy brushless motor 18?? ?
Brushless motor ESC: Kingkong 10A (12A) to confirm
RX: LemonRx 6 axis
Chasis: 3D printed, CF and titanium/Polycarbonate

Will update this as I go.

I like the idea.

Kingkong escs are awesome. I own 12 of the things SO CHEAP & SO GOOD. Nice to see another drum spinner. Best of luck.

Today i received the final piece of the puzzle, my 2 Lemon Rx have arrived.
I bought 2 of them so the total would be £14.63 ish, just under the import duty price,so i would have to paty the additional £8 plus customs charge. I would have bought the 5 pack, but it would have cost the same if i bought 4 from UK in the end.

I have the package and yes i was not charged duty, but i noticed they are labeled as gifts (which they are... ) and that they are valued at $2.30 (which they are... ) so i guess if i bought the 5 pack, they declaration would have been less than the (actual... ) cost.

Oh well, i can now model the final part of the puzzle and see what the weight is coming in as.

Yeah, I've bought 10 packs many many times from them in the past and have never been charged duty... these nice men in china are always sending me gifts

Today I managed to get to use my milling machine at lunch time, and am very impressed by how well the mill left the edges of the acrylic (pinched from model making) I will be using carbon in the final one, but I do like the clear plastic look, although it would shatter, anyways, my chassis base is printing and the test sides are done, awaiting to fit it together.
Sadly I cant seem to get the url for the images to copy on my iPad, so please take a look at my Flickr pages for the pics, I'm really impressed by the finish from the mill, no post processing... And I must buy a cheap chopping board for some good plastic!

Changed to my laptop, pics here:

Acrylic test sides milled in milling machine. No post cleanup!


Looking good, I love this machine! Much better than my first printer back in 2009!

Sorted the images!
Anyway, if anyone wants to have some 3D printing done, feel free to drop me a message (UK) as i need an excuse to use my MANY colors!







And the weight...

[Roboteernat]

I have been working on a new chassis for the ant, and so far this is what i have come up with


It looks a bit sporty on its own i think, but the spoiler is meant to be a back guard from the drum.
I have had the ant driving around and spinning up against my old ant chasis, and i am very impressed, although i would be dumbing down the speed of the drum so that it does hit, but doesnt knock me around the arena incase it too throws me out!

Looking very impressive so far can't wait to see it in action.

Just an update to the design, shall try and print this tonight and see how it goes, once i have it printed i can set to removing excess plastic for much needed weight reduction!
