Great Work so far M-bot. while many of the filler pictures are a little samey, it's still interesting to see where you can and can't fill due to transformation.

you're modification of the foot was a great idea, the only suggestion I might have made was to fill some of the space behind the plasticine with some small ball bearings, magnets or some other denser material to increase the local mass. I guess it's a little late now.

I'm looking forward to your next update.
