Many office workers have a tiny trash can near their desk, which regularly overflows forcing janitors to make repeated trips to hundreds of tiny trash-bins scattered across an office space. It is inconvenient and unhygienic for office workers to sit next to days old trash, and it’s inefficient and a breach of privacy for janitorial staff to check hundreds of possibly empty bins which may be located in sensitive areas. Thus we have decided to build a personal assistant robot that can take out an office worker’s trash can and bring it to a centralized dumping ground, where janitorial staff will empty dirty bins and place clean bins for pickup.
