What it does
This solar-powered automatic lawn mower autonomously trims grass using renewable energy, smart navigation, and weather-resistant design — solving issues of noise, pollution, and labour-intensive lawn care.
Your inspiration
Frequent rain, heat, and humidity in Malaysia make traditional lawn mowing exhausting, unsafe, and unsustainable. The idea came from a need for a cleaner, safer, and smarter alternative that works in local weather conditions and supports greener living.
How it works
The lawn mower is powered by solar energy and stores excess power in a rechargeable battery. It uses ultrasonic sensors to detect obstacles and navigate autonomously. The system includes a motor-driven cutting blade, weather-resistant housing, and rain sensors to pause operation during wet conditions. Rear-wheel DC motors drive movement, while a caster wheel ensures maneuverability. The design was developed using SolidWorks, and the prototype is built from plywood and 3D-printed components.
Design process
We began by surveying users to understand pain points in lawn care. From those insights, we brainstormed ideas, evaluated alternatives, and developed CAD models. We selected components, fabricated a prototype using affordable materials, and integrated electronics. The design was tested and refined through motion simulations and real-world trials. Safety, sustainability, and affordability were central to every design decision.
How it is different
Unlike conventional mowers, our design is tailored to Malaysia's tropical climate and fully solar-powered, eliminating fuel costs and emissions. It adds smart automation, rain detection, and obstacle avoidance to ensure safe, low-maintenance, and eco-friendly operation — filling a market gap for sustainable and intelligent lawn care.
Future plans
We plan to enhance obstacle detection using LiDAR or GPS, improve waterproofing, and develop a mobile app for remote control. We also aim to replace the plywood body with more durable materials for long-term outdoor use and explore commercialisation through crowdfunding or partnerships.
