Vex Planetary Gearset Video: Up close and why people don't use it


Is that something which you’re planning to use on your team’s robot?

Looks awesome! Never thought of this before, but it’s a great concept.

In response to @CarCar, no, they’re not going to use it. It is bulky and inconsistent when driving. (Specifically in torque mode.)

Would it be a good use for anything else other than a drivetrain?

It may have been in the video, but I didnt catch it.
What are the uses for a planetary gear system? Do they allow you to drive multiple mechanisms?

The use of the planetary gearset is very briefly touched on, mentioned around 1:15

tldr; You use the gearset to get 4 different modes of varying torque to one shaft, of which only two of the modes has the full power of both motors.

Because the guy in the video said it at 2:00 that it doesn’t give enough torque.

@technik3k was explaining it here:
