Shawn & Lara need a Toolbox... Droid?

FINALLY!!!!!  The drivetrain's (mostly) together and.... it works!



And they said I couldn't get it to turn...

Of course you don't see the attempt on the carpet here.  *way* too much friction on carpet.  Not only can't it turn on the rug, but it threw the chain off the motor sprocket on one side.  Probably because I haven't bolted the wheels yet, so they can slip sideways.

The last few seconds I try to show that the Lego bits on the track pads actually are used by my inverted-sprocket wheel thing.  

None of the Lego is glued.  The individual links in the tracks are connected with TPU printed hinges.  (See previous post)
