Berzerker - undercutting bar spinner - 2010

[RogueTwoRobots]

Nice to see that it's starting to come together, although the pic of your beetleweight chassis just made mine look like a pile of rubbish :P

Are you hoping to have this all up and running to compete at the UK champs? Or just taking it steadily and it will be built when it's built?

Will be indeed running at the UK champs

Progress today - made + installed the drive motor mounts for the beetle out of some 10mm UHMW and hooked up the electrics, it's just about driving - or would be except I ordered 2 inch wheels instead of 2.5! Too small in other words, and get hung up on the bolt heads. I'm going to get some low profile cap screws and slightly bigger wheels - next step will be to mill out a timing pulley and press fit over the brushless motor can, as well as make the dead shaft for the weapon.

The feather - starting bending up the frame which I never DID get done due to the uni press brake being broken for the longest time and then finals coming up. An annoying job involving two big propane torches and many, many jigs.

Frame done, just needs cleaning up welds with the grinder and then paint.



Edit - in other news, made the longer shafts for the brushless motors, mounted the timing pulley to them, and made some progress with wiring the thing up. Put the armour on the 3lb, still needs that little bit of machine work on the pulleys and a weapon blade.

Looks really good mate. Hopefully it will be ready for a test drive soon by the looks of it

Driving, needs a bit more machine work to get the spinner done, but not entering UK champs anyway due to other issues... oh well.

I'm currently busy with a vaguely related project - custom field oriented sensored brushless controller got it mostly working on a development board to the point that the little brushless I'm using for testing is spinning away happily! Field oriented control code however isn't totally sorted, and more to the point the development board will only handle like 6A while the actual controllers need closer to 200A - we shall see how this goes.

Hopefully it'll mean no more controller worries though!
