Triforce 3 - Build Progress Thread

How big was the hump it got stuck on initially?

30-50mm ish

[Albear]

these councils though really need to up their game on road building

If youve ever been to Hertfordshire you'll realise how good the roads in the video are lol

Hopefully there wont be too many speed bumps in the arena lol

Got all the welding done over the weekend, its now actually starting to look like a finished bot (minus assembly).

The ring with the gear welded inside it.



All the plates, still need to go round them with an angle grinder and clean them up before I paint them.


The bottom plate warped quite a lot, so will need to put a bolt through the center and pull it back down flat.


Drive unit meshes in the gear!


Just need to put the thing together, wire it up and paint it now. Next thing is to test the drive with full weight.

I have to admit. Impressive in total, but I'm not so happy on the welds. Especialy the ones for the teeth scare me.

Which teeth? The big ones on the ring I am a little worried about. So we are getting a second ring made all in one piece for fighting spinners. Also works as a spare when the teeth fall off the welded one.

[maddox10]

The big teeth that do the work destroying the opponents. A Monoblock spare disk is a good plan. I think you'll need it.

On the gear-rings. I hope you will do the spare disk with full length teeth.

We stripped Mod 2 gears in Kashei, our featherweight with an electric axe... Just to give you an idea.

[TechAUmNu]

The main progress the last month has been on the electrical side with the A200S controllers now working properly (See this thread), on the mechanical side it has mostly been grinding and painting.

Assembling some ESCs, they stack in the bot sharing heatsinks to save weight.

Grinding and painting. The extra bar on the bottom plate is to reduce the warping enough to put it together lol.

We managed to assemble it today! Found a few issues with the fit of some of the modules so will need to redesign the wheels units a bit to make them easier to put in. But I think its certainly looking the part now.

[Maxamuslead]

looks great, what is the current weight ?

[TechAUmNu]

Haven't weighed it yet but was projected to be about 1-2kg over last time we did. Although that was based on guessing the weight of electronics, wiring, welding and paint.

[TechAUmNu]

The weapon module is finally finished. Weighs 15.4Kg which is only 1.8Kg more than an Etek-R, but 2-3x the power.
We gave it a spin with a drill and it works really well spinning the ring. Now just to hook up some batteries and see how much power it takes to start up the ring.

Which motors are you using to power up the weapon?

[TechAUmNu]

3x 150cc rotomax with hall sensors

[TechAUmNu]

So we fired it all up and it spins nicely, limited it to 200 rpm and it only needs about 60A on one motor to maintain that speed.

Here is a test of the weapon module at 60% speed (I did also do it at 100% but forgot to film),

I need to move the bearings to the other side so they can't pop out.

[maddox10]

Or cap the bearings with button head screws. Something standard on Industrial machines.
(Rovema is notorius for that cheap easy trick)

Maybe using that Revolt RV160SH you have there to replace these 3 Chinesium monsters...
