You might draw enough current just turning all those gears to actually brown out your RoboRIO. At free speed.

Give me enough gearboxes and I'll move the world.

I wonder how much voltage you can apply before a sun gear shears off? Also which one will shear?

I imagine this will happen even if nothing is connected to the output shaft.

Efficiency? We don't need no efficiency!

Reminded me of this.

Cool, looks like it's a good start to the 10,000 year clock construction.

A few more stages, some threaded rod and a pointer and you can mark it DONE!

Unless you know of an easy way to generate 2,882,400 in-lbs of torque! (Assuming the BAG motor is stalled at an input torque of 3.5 in-lb)

Is that accounting for any backlash (or i guess forward-lash?) in between the gears, especially on the final gears?

Reminds me of the time I asked a freshman to grease the gears in the gearbox they had assembled. I came back 5 minutes later to find an absolutely perfectly even coat of grease on both sides of the 50T gears - none on the teeth. A true artist.

Still a little too fast for art:

Maybe your student thought you folks were using it to launch real boulders.
