Ok......You want motor mount designs....your teacher says something about 47's.....I think he meant my teams motor mount designs that are located in the White Papers sections of 47's website....
Now for those motor mounts....There are 2 versions....
This version uses 2 motors Drill motor coupled to back of fisher price motor---not for the faint of heart
Dual Motor Mount/Gear Switching
This version just uses 1 drill motor....
Motor Mount/Gear Switching
This version is pretty simple....and has been used and tested by many teams...
