The Ball Knob functions as a manual interface that allows controlled hand input for operating the drive hub and steering related controls. Its rounded form enables smooth gripping and rotational and directional movement when connected to levers and control shafts. It supports gradual engagement, disengagement, and adjustment of connected mechanisms. The ball knob translates manual motion into mechanical movement by transmitting applied force through the control linkage.Attributes:• Provides manual grip for control input.• Transfers hand motion to connected linkage.• Enables smooth engagement of drive functions.Applications: The Ball Knob is used for providing manual control input to drive the hub and steering mechanisms to allow smooth engagement, adjustment, and directional operation.
