1. A robotic paint repair system, comprising:
a consumable abrasive product configured to abrade a substrate;
a tool configured to drive the consumable abrasive product to abrade;
a robotic device configured to manipulate the tool; and
a compliant accessory actuator positioned between the tool and the substrate, wherein the compliant accessory actuator is driven to apply a desired force and a desired stiffness to the consumable abrasive product in response to sensed data collected between the tool and the substrate.
