Cleanroom Cleaning Robot

Design and construct a system that can be used to spray sanitization solutions on the floor of a clean room used in the production of clinical drug products. This system will able to complete its task by itself, a fully automated process. Using an existing Roomba vacuum cleaning device, we will modify and rebuild parts of the device to scrub a clean room floor.

Clean Room Roomba
Problem Statement: Design and construct a system that can be used to spray sanitization solutions on the floor of a clean room used in the production of clinical drug products. This system will able to complete its task by itself, a fully automated process. Using an existing Roomba vacuum cleaning device, we will modify and rebuild parts of the device to scrub a clean room floor.

Project Description
Design Goals
 * Spray sanitization solutions on the floor of a cleanroom
 * Scrub floor clean
 * Use UV lighting to aid in the sanitization process
 * Automatically return to charging/refill station when needed

Rough Concept
Main Ideas
 * Detachable tank that holds the cleaning solution
 * Detachable for easy clean
 * Able to do one cleaning run before being empty
 * Holds about 2 gallons of cleaning solution
 * Sprayer to dispense the fluid
 * Controlled by the Arduino Mirco to spray at right times
 * Alternating spray
 * Sensor inside the tank to communicate to Roomba

Testing

 * Weight Test
 * 15 lbs put on the Roomba
 * Tested how long the Roomba could last with the weight
 * 2 Master-Carr catalogs is about 15 lbs
 * Confined an area to test
 * Able to handle 15 lbs for a solid 2.5 hours
 * Pump Test
 * To see how much fluid the pump could spray
 * Used the amount of voltage that the Swiffer Wet Jet uses
 * About 400 mL per minute is the results of pump
