(Gear Shift)
I saw a team at worlds show of a gear shift idea that was chained.
and wanted to make one this year but didn’t know how and wanted advice.
What kind of gear shifter are you looking to build? Do you mean something that actually shifts the chain like a bicycle?
The most common way to shift gears is to use pneumatics to push an axle with a few gears on it so that when the pneumatic piston is in different positions, a different gear is engaged.
