Abstract: Misalignment in a spraying end effector relative to a distal end of a robotic arm can cause unintended deviations to a width of sprayed band of material and/or cause an untended offset of the sprayed band of material relative to the intended center line. To address misalignment, an alignment tool can be provided to ensure that a rotatable spray tip and a rotatable spray guard of the spraying end effector maintain a fixed alignment relative to the distal end of the robotic arm. Misalignment in the pitch and roll axis can be effectively reduced or minimized by the alignment tool, so that the resulting sprayed band of material can be consistent over many sprayed bands. Also, the sprayed bands can have an accurate or intended width without a significant offset from the intended center line.
