Re: elobire's build thread

yeah, that would be useless as armour, 3mm seems pretty soild

Re: elobire's build thread

The cheapest I've used are hopeless at low amps, even then 6mm is fine but 3-4mm touch and go. But now we know it's 0.6mm that makes much more sense!

Re: elobire's build thread

0.6mm, that's next to impossible to weld with good results, unless you have top of the bill welding tools.

I would glue it with TEC7

Im just going to use it for the bottom of the robot i think, so i can reduce some weight for thicker armor elsewhere. Thankfully i didnt buy much of it.

.6mm steel =5mm HDPE

5 mm HDPE stops some respectable attacks.
0.6mm Steel will be dented and ripped just by looking sternly to it.

Re: elobire's build thread

Havnt updated this in a while. The robot has once again gone on hold, due to the price of building it. Its a shame as i already have most of it and have probably spent £250 building it already, but other things seem to come first.

Hopefully it will be done by the end of summer, but i very much doubt it
noticed that i forgot to post pics of the new chassis, il try get them up soon.

Re: elobire's build thread

i spent £250 on an Antweight
a good one though
i regret spending that much on it but i know it is awesome.
if money is tight try using micro switches or relays for drive.
you could even get supermassive servos
lf you stretch the belt enough you won't need extra sprockets
i plan to build my first fw soon but am summing up what i think i should use from build diarys
axes look cool and quite easy for beginners
good luck though
PS 6mm polycarb is cheap as hell on eBay A3 size for under £10
that will take a few hits

Re: elobire's build thread

We have almost everything needed component wise,apart from batteries as the ones i bought are far from ideal. The problem with money is buying the material to make the chassis from. It really wont cost much more than £50 to get completely finished, but at the moment its money i cant spend.

Re: elobire's build thread

Pictures of the chassis as it is now. Started doing a complete rebuild, but i was stupid and spent £50 on sheet metal that was too thin


i think il just give in and make the frame out of box section and then put some hdpe or similar as armor. This has been going on way too long for my liking and i would really like to get into an event this year.

Re: elobire's build thread

good start look nice and solid
what thickness did you go for now

What you can see on there at the moment is 0.6mm hdpe, but thats coming off because its obviously too thin. Going to be replacing it with i think 12mm hdpe, maybe thicker if i i think the weight will allow.

Re: elobire's build thread

Looks a bit shiney for HDPE, is it not 0.6mm steel?

[RogueTwoRobots]

Re: elobire's build thread

Looks like it's been welded to the steel box-section as well. Never knew you could do that with HDPE

On a more serious note, was the £50 of too-thin sheet metal bought from B&Q? If so, don't bother buying any metals from there. All the sheets they sell are too thin for the majority of roboteers' needs and the prices are just ridiculous. Either go on a scrounging mission around local recycling centres or scrapyards, or check through eBay.

The sheet on there at the moment is steel, i havnt ordered the HDPE yet. Its hardly welded on there anyway, the welder just melted through it even at the lowest setting...

Im going to finish making the frame out of box section first, then see what sort of weight il have left to play with. its probably not going to be finished till the end of summer though.

Yea, i was amazed at the prices there, it cost me about £50 for two 500x500 sheets and the box section was quite expensive too.
