| # Team Members: - Angelo Santos (angelos4) - Sahas Munamala (sahasrm2) - Lisa Pachikara (lisamp2) # Problem It is common for many residents to encounter mail that does not belong to them from prior tenants. The documents may contain personal information about that tenant that could risk security threats and negative legal implications. There are also many occasions where tenants currently living in apartments get unwanted mail from senders they would like to blacklist, or from advertisers. # Solution We propose a mail sorter and shredder that would organize mail based on the names of the tenants and the senders that are allowed/blacklisted from the mail system. Names on the allowlist are sorted into the respective bins. Blacklisted names are sent to the shredder. This would be done by scanning the mail, extracting the necessary information from the labels of the mail, and comparing all features to determine bin placement. # Solution Components - Raspberry Pi - Camera x2 - Microcontroller - Laser Block sensor - Motors x3 - Shredder # Subsystems ## Subsystem 1: Mail Recognition/Detector This component will consist of an optical switch connected to the main control unit that will determine if mail is placed properly in the scanner. It will also contain 2 cameras and light sources to capture both sides of the mail. ## Subsystem 2: Main control unit Controls the image capturing of the camera based on the optical switch, and runs an OCR to determine the sender and receiver from the printed or handwritten text. It will then compares the data to names/aliases within a local database to determine the destination of the mail being processed. Further, it will send control signals to different electric motors in the organization system. ## Subsystem 3: Webserver We will run a webserver hosted on a raspberry pi. This web server will be responsible for updating the machine's internal filters. ## Subsystem 4: Organization System This is the physical system that controls the directional movement of the documents such that it reaches the intended destination. # Criterion For Success - Mail sorter can sort mail into individual slots - Mail sorter can read mail and extract necessary information like addresses/names from images of mail. - Mail sorter settings can be set remotely - Mail sorter can shred |
