In my opinion, differential gears are unnecessary for IQ drivetrains. I mean, just use omniwheels if you want good turning, because in almost cases omniwheels will be better in efficiency, and turn speed.
The only two reasons I think you would want this kit are:
-
The other pieces (bevel and side connecter)
-
If you want to build an off season non competition robot. (E.g. Vex IQ Snake)
