About this creation
This is, obviously, the second version of my Babushka Bot idea. In essence, it is the same as MK. 1, the only real differences are that the carrier has wheels instead of treads, higher ground clearance, and a lower gear ratio in the drive train. The tires give it far more traction and off road (ish) capabilities. This seems fairly counterintuitive at first, but the combination of increased traction and torque makes a HUGE difference. The MK. 1 could not even climb a rise of approximately 1/3 an inch. The MK. 2, however, climbed a rise of around 2.5 inches without much difficulty. The inner robot has roughly the same capabilities as the original, however it is much rarer for loose objects to get jammed in the drivetrain because the gears are replaced with chains.

Well, I think that's about it, enjoy!


It may make it easier to understand the pics knowing that when the small robot is in the carrier it faces the opposite direction of the carrier

Quoting Ian F Very clever design. I love the idea. I wish I had camo duct tape…
Thanks man! I'm considering attempting a "3-layered" version... but I'm not sure if it'll work... and yeah, camo duct tape for the win!

Quoting Jay O'Bee Is that camo duct tape in your building area?
Haha, yeah, actually. I needed a way to "LEGO-proof" the boards 'cause pins and stuff kept falling through, and the camo duct tape was just lying around.
