This is my latest version of a rover with differential transmission. In the
accuracy department, I'd have to say it's my most favorite, but it leaves a lot
to be desired in the way of speed - the worm gears slow it down a lot.
In the course of designing I've found that two hypothetical LEGO parts would
make the differential transmission even more compact and streamlined. I don't
suppose these exist, anyone?
1) a "backwards" worm gear (threaded the opposite way from the current one);
2) an axle "intersection" enclosed in a 2X2 brick that would transfer rotation
from two axles across each other, on the same plane, without interference.
