# Photoresist bottle replacement system

## Abstract

The present disclosure describes a method for replacing a photoresist (PR) bottle using a vehicle. An exemplary vehicle includes a processor configured to receive a request signal to replace a first PR bottle. The processor is also configured to transmit an order based on the request signal. The vehicle also includes a plurality of wheels configured to move the vehicle from the first location to a second location, and from the second location to the first location. The vehicle further includes a robotic arm configured to load, at the first location, the first PR bottle into a first container; load a second PR bottle in a second container; remove a cap from the second PR bottle and a socket from the first PR bottle; couple the socket of the first PR bottle to the second PR bottle; and unload the second PR bottle from the second container.
