Tormenta 2 - Build Diary

Re: Tormenta 2 - Build Diary

Domestic 230v is brown/blue/earth colour

Industrial 24v is blue and white/blue

Automotive 12v is red/black

3 phase industrial is brown black grey in England, some places still use red blue yellow or black for all 3

I use red black because it's the same colour that comes with the lipo's etc and it keeps it all simple

I believe we're fighting in April so, uh, you got any video of Robob? For seeing how the ratio change affects things, of course, pfft. :wink:

Re: Tormenta 2 - Build Diary

Well the way to make this robot reliable is to stop the overvolting. There is no loss of top speed by changing the motors to 18v and going 24:1, only a bit of explosiveness. Would be a shame to lose that, but you can push a robot with bosch 35s if you can get underneath, so the way the machine works would be the same.

And it would probably improve my driving, having everything a bit calmer.

That would cost something like 60 quid to do. Very little to pay to gain reliability.

-------------------------------

We're also overvolting the lifter motor. Recently it smells of overworked motor even if you run it literally for a second. We don't know the history of it (found by some bins), so for all we know it has always been close to going home.

Looking at this as a replacement motor: http://www.pollin.de/shop/dt/Mjk0OTg2OT ... 5G_AS.html

The can looks to be almost identical to the one in the drill. We'd lose some power in the weapon, but it has buckets of it, so it shouldn't be a problem. And for that money it's worth getting one to find out.

-------------------------------

Other than those potential upgrades (downgrades?) we updated the wiring last night. Thinking about putting some bike tyre on the blue wheels as with just 3mm of clearance I'm worried about bottoming out at the champs.

Re: Tormenta 2 - Build Diary

It certainly doesn't seem to be lacking any power. Are you running 18v motors on 6s? ^

We bit the bullet and got what we need from Gimson to make this change. We also ordered what we think should be a replacement motor for the lifter. All in all, Tormenta 2 should finally be on the road to reliability.

Re: Tormenta 2 - Build Diary

Four 18v 24:1 Argos-cased motors with two hacked 85a escs on 6s 4800mah lipo. It's a lot better than I originally envisaged it to be.

Re: Tormenta 2 - Build Diary

Are you running 100mm wheels? If so that thing must rocket!

Also means all 3 robots (Robob, T2 and 720) will be 10mph+, it's going to be an intense fight!

Re: Tormenta 2 - Build Diary

It's running 75mm wheels, the wheelbase is so short that speeding it up any more may make it uncontrollable. It's already crazy enough as it is!

Re: Tormenta 2 - Build Diary

As we wait for the stuff from Gimson and the replacement motor for the lifter we've done a few little bits.

Here's what she looks like as of tonight. There are a few more on photobucket: http://s1088.beta.photobucket.com/user/ ... rmenta 2

Eerie. Effin eerie. I've got to get a picture of those two together. It'll be the spot the difference puzzle in the next FRA newsletter.

Haha, can you send me a picture? My memory of Kaizer is black HDPE and low forks, or has it changed?

Re: Tormenta 2 - Build Diary

Kaizer is flat pack ATM for the installation of Gimsons & new batteries. I'll post side by side pics when I can.

Outside has changed very little except the forks are now off the floor, about half way up the front, to give the new actuator better leverage.

With thanks to Dave Weston BTW for whom this upgrade couldn't have happened without.

Re: Tormenta 2 - Build Diary

The Gimson stuff has arrived! I'm very surprised at how quickly, too. The packaging was almost impenetrable, all parts bubble wrapped nicely. Impressed!

So now begins the make-a-massive-mess-on-the-dining-table-fest-2013 which is taking apart everything and putting it all back together cleaner, and with these new gearboxes and motors sorted. Assuming no catastrophes there should be a drive video by the end of the day.

That said until I get my hands on a completed gearbox I'm unsure what the game is in terms of additional spacers. The gears are quite a bit slimmer, that slack must be taken up somewhere. Does the addition of nylon/metal washers on the Gimson site also apply to drill gearboxes, or just the GR02? If anyone with experience can let me know, I'd be grateful. I'll go and make a dummy gearbox up and make my own analysis.

Feels good to have something hearty to do on the machine, feels a bit like doing 4 organ transplants back to back.
