Team Coolspeedbot: first feather weight robot

[Coolspeedbot]

It was firmware that was provided for me already to flash, by another person. So I've not had a look at the firmware itself.

[Roboteernat]

Just wondering what firmware you used to convert them back to brushless?

[Coolspeedbot]

They are the old BotBitz BB-85A, I was running them as brushed ESCS in CSB 1 but I converted them back to running brushless motors.

[Sam_Gad]

Looking like a powerhouse! What ESCs are you using for your brushless drive setup?

[Coolspeedbot]

Thanks, would put out 9-10 mph currently if it had wheels on, but when it runs on the 5s lipo I'm planning to use it should put out 12-13mph.

[Eidg]

Looks very powerful.

And here is a bench test of the drive: https://youtu.be/oQ8gEGHQQuw

Been a while. Coolspeedbot 2 is getting there wiring nearly done the bodywork nearly fully put together.

I did a weapon test which you can find here: https://youtu.be/JjuGP6iDMoc

Ok got new hole punch coming along with a proper scribing tool should hopefully help a little.

[Eidg]

Or you print a drawing out an glue it on the part as a mark template.

Jigs work but can be a pain the that's ass. Just measure and measure and measure again. One option if you get deep pockets and space is a 3axis sliding table and a bench drill. Or a mill.

I assume there's some kind of magical knack to getting holes in the right place when drilling metal...

If you're making lots of piece of identical ally bar, is it worth making yourself a little jig? A scrap piece of metal (or even plastic/wood) with some 2mm through holes drilled in the exact right places. Clamp it to the piece you're working on, then use the pre-existing holes to line up a 2mm drill bit. You'd only need to go in a couple of mm on each hole with the jig in place.

Might be a bit of a faff to make but that way you only have to be accurate once.

Oh, and the robot looks awesome!

I used one of those spring-loaded punches on Voodoo's aluminium, works an absolute treat!

Oh ok

[Coolspeedbot]

Hmm. Maybe try one of those spring-loaded punches? Not sure if they'd be good enough for hardox.

Hardox? don't you mean the aluminium bars?
