The Singapore Prison Service (SPS) in collaboration with the Home Team Science and Technology Agency (HTX), has created Prison Automated Screening System (PASS), an automated toilet that uses robotics, sensors, and deep learning to collect urine samples and screen them for illicit drugs. PASS is an attempt to automate the urine procurement and screening process in a fully unsupervised and hygienic manner. The technology is currently being tested as a proof-of-concept until February 2024, with four testing units deployed at various centres across the Southeast Asian City-State. At the beginning of the screening procedure, supervisees are automatically registered using biometrics technology. This allows the system to be completely contactless and unsupervised. Other features include an automatic door, a urinal shutter, and sensors that ensure that the user provides the urine sample at the right time with all steps conducted in the right order. The supervisee waits in a cubicle for the test result, which takes about five minutes. An instructional video is also played inside the cubicle, which guides users through the entire process. Behind the cubicle is a specially designed robotic gantry system that handles the test kits. Technology safeguards and deep learning aid in detecting and preventing tampering, ensuring the testing is accurate, consistent, and free from contamination. Singaporean authorities plan to deploy PASS nationwide. They say this would help them to make Singapore a drug-free state and help their citizens to live a more fulfilling life, free from drugs.
