Tashic's Robots

[Tashic]

Since I'm starting a new antweight and finishing my first fw, I decided to make one thread for all my works.

This are the antweight that I made (some are dismantled or modified):

Sweet antweights mate, I love the 6wd one.

[Tashic]

Thanks Harry!

Some updates:
This is the antweight that I was working on for some days:
IMG_3092.jpgIMG_3093.jpgIMG_3094.jpgIMG_3095.jpg
Made from brass rods welded with solder and bolted 0.5mm alluminium plates.
The green stuff in the wheels are rubber bands for added traction.

plus, I put in this robot the name on the top:
IMG_3096.jpg
Yes it's called stormer 2.1
It's inspired by another robot.I let you guess which one.

and something that I did a while ago just for the look:
IMG_3097.jpgIMG_3098.jpg

and last I bought 2 red leds for the featherweight, witch I will call Black Wood, for obvious reasons.

[Tashic]

News!

Added the name and the leds on the back!

And I did a little drive in a basketball field near my home.
There was broken glass, so the scoop got some paint removed.

I think that I can consider this robot finished, as I dont plan to modify it.

For the second featherweight I plan to make a 4wd robot with a hammer.
Would a starter motor from a small car or a motorbike work for a hammer?

Thanks in advance.

[harry hills]

Starter motors tend to suck a lot of current so they may not be much use. Scooter motors seem popular. Paint job is sick and the name is cool too!

[Tashic]

Thanks Harry!

I finaly got a video of Black Wood running, slowly because the batteries were low. I'm charging them now and tomorrow I will get the real video.

I'm driving and my dad (that helped me building the robot) is filming.

Here's the video fully charged:

Now here's the things to improve for the next FW:

Better reliability using speed controllers, add a weapon, make better wheels, have 4wd, better materials and a better battery.

Scooter motors work great for axes/hammers, my robot Hatchet uses a 300w scooter motor which swings a 1.5kg axe with no trouble at all

[Tashic]

Thanks for the info Mrsam.

I almost finished my ant, it just needs the side pannels, but I want curved in a strange way to fit this:
IMG_3120.jpgIMG_3122.jpg

Is there a way to curve 0.5mm thick in this shape?

EDIT:
My dad accidentaly found this site http://www.titalia.it/en that sells and cuts titanium.
We don't know the price yet, but what would be a good thickness for a featherweight and a good price (of example a 1mX1m sheet of that thickness)?

[Tashic]

Today I have contacted titalia and they recomended the grade 5 for a 4mm sheet.
What do you think? What thikness and type of titanium is better?
Thanks in advance!

[harry hills]

Grade 5 is generally considered the best grade. Will be very expensive though. Which competitions are you likely to fight in?

[Tashic]

Probably in not very serious competition, that's because I asked, and maybe I don't even need titanium in the first place, but I was just asking for later robots.

[Liftoff]

Interested to know what prices you were quoted for gr5, 4mm thick Ti

[Eventorizon]

Same here, it is great to have Titanium for certain key components which need to stay rigid and straight like motor mounts.

As for thickness's here are some examples...

Conker 3 - 3.6mm Grade 5 base and top armour to stop axes and spinners.

Little Hitter 3 - 3mm G5 front and 1.5mm G5 sides capable of surviving the most powerful spinners, just.

Mr Mangle - 4-6mm G5 welded unibody, incredibly strong and rigid but exposed top.

Binky - All armour and Base plate 2mm Grade 2. Slopped and able to deflect most blows, can be bend back into shape.

Beauty (1- - Tubular titanium exoskeleton design, can survive spinners but welds break eventually.

It all depends on what you want to do with it. Some Beetles and ants use it as scoops. If its a light event, even with spinners then 1mm of G5 may be enough but if you wanted to come here you may need at least 2mm depending on the design.

[Tashic]

Chris grade 5 titanium is 70 € (about 57 pounds) for every kg, not counting the cost of cutting.

Alex, the next robot will have sloped front and sides, so is grade 2 good enough for non spinner battles?

In a 4wd robot with a motor on each wheel, if I put a belt and link the wheels on each side, is going to be better than without the belt?
The idea is that if the front or the back is lifted, i still have the power of all 4 motors.

Plus:

Made the side pannels on the ant:
IMG_3126.jpgIMG_3127.jpg
But, as expected, is overweight by 8 grams:
IMG_3125.jpg
Everything else is completed, I only need to bring it to 150gr.

And are roller skate wheels good?
Because I found my old skates, so I have 8 of them:
IMG_3128.jpgIMG_3129.jpg
The diameter is 76mm.
A problem could be attaching them to the motor axle.
