Still waiting on the servo so in anticipation of an upcoming project involving building a line following robot, I decided to go ahead and put together the 4-Wheel robot base that was loaned to me by MakerShed...
It's a solid base... this thing is designed well. I did find that the online instructions for building it didn't match up exactly to the parts I have (the black metal frame pieces are slightly different in the number of holes but that wasn't a problem) and the photos don't really show the motors being held to the frame with the long machine screws that came in my kit... but it's not difficult to figure out anyway.
The upcoming project uses a 2-wheel robot frame along with a caster, but since I have a 4-wheel version I'll probably have to modify the code a bit to control 4 wheels... or just hike the base up on a home-made caster of some sort... will cross that bridge later... I may actually break down and buy this thing from MakerShed as I can see it being a really nice base to have for future projects... BTW, there's a bunch of small add-on parts for holding sensors and such that I haven't attached in the final image here.
