Get Gear Ratios #32

Closed isabellebowdey closed 2 years ago

isabellebowdey commented 2 years ago

We talked to to fab about Gear Ratios: wheel diameter - 6 inches (Side note: circumference and diameter changes as wheels get worn, there can be a range) SIMbox gear ratio - falcon to shaft is 1 to 4.67 (4.67 is falcon) Sprockets ratio (sprockets/simbox to drive train) - 12 (output of box) to wheels is 30

These are calculation notes for future reference. Counts per rev on motor = 2048 1 / 4.67 times 12/30 = 0.85 0.8565 times 1 falcon rotation is 1.614 inches of the robot inches of the robot /2048 = 0.000788 inches per tick

so our final formula to use is inches traveled / counts per rev = inches per tick

UPDATE: What we did in the code image

1 falcon rotation is 1.614 inches of the robot

Done with getting gear ratios as far as I'm aware.
