Operator Controls

Joystick 1/Left

Button/Axis	Description (brief)	Operation	Notes
Y-Axis	6Move Forward/Backward	In Left/Right mode, this moves boths sides of the drivetrain; otherwise this moves just the left side of the drivetrain.
X-Axis
1/trigger	Shift	On button press shifts to high gear. On release, shifts to low gear. Only one trigger needs to be pressed.
2	Raise center wheel	.Wheel remains rasied while button is being pressed (or button 2 on right joystick is being pressed). Wheel lowers when both button 2s are released.
3	Left/Right mode	In Left/Right mode while this button is being pressed (or button 3 on right joystick is being pressed).

Y-axis	Move Left/Right	In Left/Right mode, this moves the center wheel left/right; otherwise this move nothing.
1	Shift	On button press shifts to high gear. On release, shifts to low gear. Only one trigger needs to be pressed.
2	Raise center wheel	Wheel remains rasied while button is being pressed (or button 2 on left joystick is being pressed). Wheel lowers when both button 2s are released.

Button/Axis	Description (brief)	Operation	Notes
X-axis
Y-axis	Move up/down	Raise/lower grips, if Level 3 Preset not being pressed. This controls speed of movement.
1/trigger	Close lower grips	Closes the grips while this button is being pressed. Grips stop moving when this button and button #2 are both released.
2	Open lower grips	Opens the grips while this button is being pressed (and button #1 is released). Grips stop moving when this button and button #1 are both released.
3	Level 3 Preset	Raise grips high enough to be above 2 totes (i.e. 2 tote stack created by human player at human player station). Grips raise and stay raised while the button is being pressed. While being pressed, the Y-axis is ignored. When button is released, Y-axis controls grip height.
