Re: Modifying Vexpro Ball Shifter transmissions
As it has been said before, there aren't solenoid that are strong enough to hold the shifter in gear.
Also, solenoids have a limit to the amount of time that they can be actuated for before they burn up, which won't work with shifters.
The solenoids remind me of the mabuchi motors (from 05 maybe?), a neat idea, but they are just too small and not powerful enough to be useful, so nobody used them.
In 2012 we used the most powerful solenoid allowed by the rules to pull a pin on our ball hopper thing. It had almost no power at all (I could push it backwards with just one finger), and was replaced at competition with a cylinder smaller than the ones normally used in shifting gearboxes.
Has anybody ever used a solenoid on an FRC robot before?
