Each tile is 23.4 inches wide.
|

|

|
||
The exact radius of 4" omni wheels, using dial calipers: 2.075 inches
|
||
|
||
2 * pi * r is circumference of the wheel - 13.0376 inches
|
||
|
||
|
||
There are 627.2 points in a revolution with the vex direct motor encoders - according to robotc
|
||
developers: “The 2-wire 393 motor measures 627.2 counts per revolution of the output shaft in its
|
||
default high-torque configuration and 392 counts per revolution of the output shaft in its
|
||
modified high-speed configuration.”
|
||
|
||
|
||
So if we do 1 revolution * distance / radius we get 627.2 * 23.4 / 13.0376 = 1206.
|
||
When the integrated motor encoder reports a movement of 1206, that means the robot has moved 1 tile.
