Nova Robots: common thread
« on: July 08, 2018, 02:51:33 pm »
So I'm finally done for now messing with my CNC mill project. Which means its time for robot updates!!

First on the docket is an update to Mr Slant. Mr. Slant kept shredding belts at Bot Blast last year but I didn't want to switch to a timing belt because that would be too easy. Also the inside of Mr. Slant is an absolute mess and making a fancy hub motor would let me clean everything up. So off to hobbyking I went to pickout some suitable motors
 I ended up picking:

Its 46mm OD was basically perfect for the space I had and it let me keep my blade height unchanged.

I laid out the assembly in solidworks

The assembly relies heavily on press fits. I was pleasantly surprised the mill is accurate enough where all the press fits seemed to work out fine.

So I clamped the prototype into the mill vise (because this blade scares the crap out of me), hooked the motor up to the chassis of Mr. Slant V1 laid a big sheet of polycarb between me and it and let it rip.

I spun it up several more times and even with the the alligator clip connections it seemed quite happy.

Next step is to modify the chassis and see if it can handle some hits.

Is this registered to fight at Bot Blast? What weight class?  That is a biiiig motor.
