Well, finally our motors and Electronic Speed Controls have arrived and it is time to get prototyping. Of course, I am typing right now but in English not Proto.
So we are there…here, where the skunk meets the road.
Better roll down the windows kids, this could get a little rough for a bit.
I have measured twice (Ok, I measured 4 times) and
printed once (Jeez, OK, twice. Big friggin deal.) and the first proto of our inside
assembly of the self-driving wheel (SDW), is as I stated back a few posts, a
nice try. It gets us closer to a real working SDW but no banana, Chimp.
Right off the bat, two issues pop out at me. One, I think
that that RPMs of the motor will drive Bob at a speed that the Super Gasser
folks at National Hot Rod Association would envy. Two, we are about 3mm shy of
actually having the motor drive gear come in contact with the wheel’s internal rotational
gear. (Got love that deep dumpster diving tech talk.)
In summary, ‘Houston, we have a couple of pretty noteworthy
friggin problems here.’
Net-net: We need to build a geared reduction transmission
that will fit a 39mm motor plus the yet to be designed trannie into a 22mm
radius by 55mm length wheel housing. (For you liberal arts majors, the diameter
is 2 times the radius. For bonus points; how far will Bob travel in one
completed revolution of his SDW? Uhm! Gotta
Google it don’t ya Grasshopper.)
Here are the current resources that we have to work with.
While I envision the next design concept for our SDW, I
decided to let the printer go on an artistic voyage and it made this very
cool visual of an adaptive network. Check out the Richie’s explanation. https://sites.google.com/site/richardsouthwell254/home/adaptive-networks
