Design and Implementation of a Robotic Car with a ULV Atomizer for Mosquito Control in Urban Parks

Mosquito infestations in tropical regions, particularly during months of moderate to high rainfall, pose significant health risks due to diseases like Malaria, Dengue, and Chikungunya. Traditional control methods such as fumigation and chemical sprays face limitations of environmental concerns and potential health risks to humans. To address this issue in community parks, I developed a robotic car equipped with an atomizer to disperse an organic mosquito repellent. Powered by a Raspberry Pi 4 and brushless DC motors, the robotic vehicle is designed for stable and efficient movement across uneven park terrains. It is controlled via an integrated PlayStation 4 controller for user-friendly operation. The atomizer disperses a repellent from essential oils such as Neem (Azadirachta indica), Lemongrass, and Eucalyptus, offering an environmentally friendly and human-safe alternative to chemical repellents like DEET. Testing indicated that the robotic car equipped with an atomizer effectively reduces mosquito presence, enhancing the safety and enjoyment of outdoor recreational spaces.
