Lara's Lego H-015 Sentry Droid

[kresty]

I'm going to have to find/post video of our outing, it was cool...  He did go haywire a bit which resulted in him knocking apart his antenna (he ran under an overhang that was too low).

I'm using the Pololu Simple Motor Controllers.  After his crazy attack, I checked the motors and only 2 were running (1st and last on the daisy chain).  Cycling power made it all happy again.

The Pololu SMC's have a safety mode, I'm wondering if they got into that mode.  And maybe why those two.  We'd let a kid drive him, so it might have been running a little more than we would, maybe they overheated?  

I might modify the code a little to query the controllers frequently and see if they've gone into safe mode.  If so, then shut down all four motors to prevent this again...

Presumably if it wasn't a kid unused to the controls we would've caught on and stopped sooner too...

Anyway, I'm reprinting some antennae.
