Wow thank you all so much for the advice!
Yes I know it is a dangerous project, and I definitely will be making a small scale version first ! (already ordered the parts for that). Yes once I get the right motor I will definitely figure how to secure it very safely to the wood and floor.
I am pretty much brand new to understanding motors (only played around with some lower voltage dc motors before), so that's why I was asking more. I will take the info you gave me and see if I can find the right motor, and hopefully figure out which hardware I can use the control it.
Thanks again for all the tips!
