1. A disc changing system for a robotic defect repair system, the disc changing system comprising:
a first abrasive disc and a second abrasive disc, wherein the first and second abrasive discs are coupled to a liner;
an abrasive disc placement device configured to automatically:
remove the first abrasive disc from the liner;
transport the first abrasive disc to a robotic tool of the robotic defect repair system; and
place the first abrasive disc on a backup pad coupled to the robotic tool;
an abrasive disc remover configured to automatically remove the first abrasive disc after receiving a removal signal; and
a controller configured to send an instruction to the disc placement device to remove, transport and place the first abrasive disc, instruct the robotic tool to conduct an abrasive operation, and wherein the controller is also configured to send the removal signal, wherein the controller is a processor and the instructions are stored on a non-transitory computer-readable medium and executed by the processor.
