oh awesome thanks, ill remember that for next time! and I was really surprised at it And its going to be even faster at 18 volts! maybe too powerful!

[Ellis]

That's badass! It looks really cool (a trait of all winning robots, one might observe) and it certainly axes! At 18v it's going to be really quite nasty. Certainly gives hope to those hoping to go axey (me) with a machine at some stage.

One of the best additions of a weapon to an already established robot we've seen in a while?

[Bodge Job]

Aha thanks! but its not really an established robot, need to win battles for that, and it hasn't won any battles since its first year at the champs, that was back when it was partially armored in wood!

Lipo has come now though, looks good and fits perfectly (probably should have checked that before i bought it though) . But what are the suggestions/rules regarding the lipos protection? its got more than 22mm Nylon in all directions except up and down, where it is only 6mm HDPE. Should I put Aluminum top and bottom? or just at the bottom? And what thickness?

And should I mount it vertically or horizontally?
Vertically would mean its narrower so slightly less likely to be hit
Horizontally with more padding top and bottom, to absorb the impacts more? and mean that it has a larger space before the Aluminum, so the aluminium could be bent with out damaging the battery?
what do people think about it?

[grant_ploughbot]

I would probably mount it horizontally, with a thin layer of foam underneath (a few mm) and the pad the top to fill in the rest.

[Bodge Job]

Right OK cool, and what about the Aluminium?
do i need it? i know its not in the rules, but a lot of people seem to be wanting/requesting it? i think its a good idea just was wondering how thick people would want it? I have some old 1.5 mm aluminium, but if it needed to be thicker I would have to buy some

Where did you get the sprokets and chain from that mount to the Gimsons and then the axe shaft?

[Bodge Job]

The sprockets are from technobots, I then drilled out and tapped the small one to 3/8 UNF. The shaft is a 12mm tube clamped between the bulkheads by 8mm studding.

[daveimi]

ar ok thats cool. Drilling and tapping is a bit like Voodoo and Witchcraft to me. I lived in hope for an hour then that it may have been off-the-shelf obtainable lol and I could have one too

[Bodge Job]

Did little work tonight, made a new thinner lighter back out of HDPE, and did a few small jobs for convinence but that's about it.


And Drilling and tapping isn't to hard, you can just about do it with a resamble cordless drill or power drill if you have one (and vice) and then you need an 8.5 mm drill (which if you haven't got you can get it in a set for £15 (although a more expensive better quality set would be a lot better) , and then tapping is also by hand, the tap being about £5 (for this size as its a less commen tap) and a tap key thing, also about £5. It's pretty simple to do, drill is really needed though, it's nearly impossible to build a robot with out drilling at some point so it's good have a good drill to use, tapping is less needed as in most sercumstances you could use bolts, but it's nearly impossible to attach a sprocket to a gimpson shaft with out it being threaded.

Did a lot of wiring and stuff recently, but while I was testing the servo, microswitch controller thing on a load free drive motor, off the 18 volt lipo, but after going back and forth a few times (nothing too strenuous) when suddenly smoke shot out the side and the brushes glowed red hot, it was an obvious burnout, and I know i was over volting it by 50% but I wouldn't have thought it would have burn out so easily? could it have been a faulty motor? and if it wasn't it would be under less strain than the Axe motor, so would that survive the 18 volts? should test on another gear motor? or what can i do about it?
