Tashic's ants

Postby Tashic » Wed Jun 18, 2014 11:23 pm

Hi from Italy!

Fortunately robot wars was shown on italy too and I've been a fan since then.
I actually started building for some years.

This is my current team:

Stormer 2.1

6WD, pusher, invertible.. You can guess the robot that this is based on.

Planning on rebuild this, because it's becoming too messy, the pieces are glued and I can't take out the wheels, and I discovered that the material craks if I clean it with alcohol.

F2
This is the lastest one and inside the alumimium pannels there is a welded brass tube chassis that holds all the components and the pannels.
All the components can be taken out with all of the chassis intact.

By the way on the dark it's awsome, because the light of the recever is reflected on the floor! :D

The older robots have been dismantled, but I saved the chassis and grouped in this sculpture/pile :

There are 5 chassis in there.

Other than the new Stormer, I'm planning to make a crusher powered by two 298:1 gearbox motors.

Bonjourno! Those are mighty impressive looking! F2 looks uncannily like an old fleaweight called Bruce.

Welcome to the forum Tashic.
Looks like a lot of work has gone into the robots I especially like the 6 wheel drive.
Do you get many competitions to go to in Italy.

Thanks guys!

This is the claw for the crusher

I will polish it later but I need something to control the motors, the battery is a 350mAh 2 cell lipo.

Petter, unfortunately there aren't any antweight competition, but I could try and make an arena and see if I can convince some one to make something similar to an ant.

Also Dave, it's spelled "Buongiorno". :)

Sorry for not posting anything for a while.

Here is the progect for Stormer 3 (not 100% finished):
Ca.JPG
Ca.JPG (108 KiB) Viewed 2945 times


Why it is pink?
Because of this:
IMG_32002.JPG
IMG_32002.JPG (196.97 KiB) Viewed 2945 times


It is going to be made with 1.5mm PCB with copper on both sides and some parts are going to be welded.
It's the same method that I used for F2.

It's a bit heavy so I want to upgrade it to 2 cell lipo.
I ordered some of the botbitz 10AMP ESCs + some gear motors a few weeks ago, but they still haven't arrived and I haven't receved any emails :( , I will send an email my self.

EDIT: It turned out that they already sent an email the 4th of july and I didn't notice it. :oops:


Update:

Made the rest of the PCB parts, soldered 3 of them and I made and tweaked the holes for the brass rods so the gears can rotate freely:

Update:

Made the wheels:

I only need to shorten the axles and the drive train is done!

I also want to change the name, because Stormer it's very lazy. Thinking of Vector, but i'm not getting rid of the 3.

Very nice. What does it weigh?

This is the robot so far:
By the way it's shinier in real life.
IMG_32822.JPG
IMG_32822.JPG (168.84 KiB) Viewed 2807 times

Right now it weights 109 grams.
I'm still undecised about the name.
Right now I'm thinking of an italian translation of something related with a storm, like Vortice, Tempesta or Bufera.
What you think I should do?

Also this is something that I did about a year ago just for fun:

It is slow but it was made to look cool! 8)

vortice is a cool name.
Featherweight under construction.

Antweight to build list: 4Wd lifter, new clusterbot, secret project, walker of some description.

Team Hectic.

Your robot construction methods are certainly unusual and by the looks of them quite effective.
I use quite a lot of PCB material myself but always without the copper so no chance to solder parts together like you.
Always nice to see someone thinking outside the box and trying new methods.

Thanks Pete!
I tried using epoxy glue, but I find it difficult to work with.
Soldering is faster because you only need to wait a few second to harden, insted of hours, and if you want to correct something you can just melt it again.
Much easier to do wire frame like designs, as you see on the crab like robot.
The only problems I found are that you need a powerful soldering iron, and it's a bit heavy.
This method was inspired by Beast at newport 2013, I actually went there to see the event live!

Edit:
Because I will use a 2 cell lipo battery, I bought the low voltage 50:1 from botbitz, is there an advantage using HP gear motors even if they aren't used at 12V ?
Right now the robot doesn't look too slow.

Ok, finally finished Vortice 3:

It was overweight by 11 grams, so I had to trim and drill many holes.
This is one of the sides now:

In a previous post you can see how it was before.
Also the bottom plate is bent in that way because the battery (250mah 2 cell lipo) is too high, 15 mm, even if in the site it said it was 11 mm.
Fortunately the wheels are big enough to prevent the polycarb to touch the ground.
And the wheels gets dirty very quickly.

Wheels look good. Custom? if so how did you make them.

The wheels are alluminium hubs that have a grub screw to lock it in a 3mm axle and I glued a rubber band around it.
The big holes have been drilled to reduce weight.
The wheel is then glued with apoxy glue to a alluminium gear.
The gears have been made by a turner.
