Automated mobile sprayer spraying and navigation

A spray system comprising:

• at least one indicator disposed relative a non-spray area of a target surface, wherein the at least one indicator is formed as a tape at least partially defining the non-spray area;
• and
• an automated mobile sprayer (AMS) configured to spray fluids onto the target surface, the AMS comprising:
• a mobile base having a lateral axis and a longitudinal axis;
• a drive system that moves the mobile base;
• a spray module supported by the mobile base, the spray module movable along a vertical axis relative to the base, the spray module including a nozzle configured to spray the fluid longitudinally towards the target surface;
• an indicator sensor configured to sense the at least one indicator and generate indicator data regarding the at least one indicator;
• and
• control circuitry configured to:
• drive the AMS via the drive system along the target surface,
• detect the non-spray area in the target surface based on the indicator data, and
• control spraying by the AMS, based on the indicator data, such that the AMS does not apply fluid spray to the non-spray area.

A method comprising:

• shifting an automated mobile sprayer (AMS) laterally relative to a target surface in a first lateral direction;
• spraying fluid onto the target surface from a spray module of the AMS as the spray module moves relative to the target surface;
• sensing, by an indicator sensor of the AMS, an indictor tape disposed proximate a non-spray area of the target surface;
• and
• stopping, by a control module of the AMS, spraying based on the indicator sensor sensing the indicator tape.
