The pandemic highlighted the urgent need to reduce contact hours between healthcare professionals and patients, ensuring their safety while maintaining effective care delivery. Determined to create a solution, I partnered with my coursemates to envision a robot that could automate routine tasks, such as drug delivery, to minimize exposure. Although resource constraints and limited funding delayed the project's start, we remained committed to realizing this vision. From 2020 to 2024, we worked tirelessly to gather the necessary resources and refine the concept. By 2024, we began developing Medibot, and through relentless effort, we completed a functional prototype in January 2025. While originally inspired by the need to manage infectious diseases, Medibot's functionality extends beyond pandemics. It continues to be a valuable tool for improving the efficiency of drug delivery to patients and enhancing overall healthcare operations.
