Inspiration
The Smart Eco Mobile project was born from a simple yet powerful observation: in a world facing climate challenges, smart local solutions remain scarce especially in emerging countries. As engineering students in Cameroon, we wanted to prove that technology can be ecological, educational, and accessible. We were inspired by real issues in our environment like the lack of eco-friendly transport for plants, the absence of hands-on environmental tools in schools, and the limited integration of AI in African innovation. KOYOTECH was created from this dream: to build useful, clean, and inclusive technology.
What it does
The Smart Eco Mobile is a solar-powered, autonomous robotic vehicle designed to:
Transport and nurture plants or sensitive biological samples in a controlled environment.
Monitor real-time environmental data such as temperature, humidity, air quality, and soil moisture using IoT sensors.
Use embedded artificial intelligence to adjust internal conditions like light and irrigation.
Serve as a mobile educational platform in schools for environmental and tech awareness.
How we built it
We developed Smart Eco Mobile using local resources and a maker mindset:
A lightweight 3D-printed mobile structure, suitable for urban settings.
Solar energy system using photovoltaic panels and 3.7V lithium batteries.
An AI-powered ESP32 controller, running on TinyML (Edge Impulse) for on-device learning.
Integrated IoT sensors for temperature, humidity, soil moisture, and air quality.
A voice-controlled interface with the wake word “Hello Eco” for human interaction.
All built and assembled at the University of Buea FabLab, by a young, passionate team in electronics, mechanics, and AI.
Challenges we ran into
Limited funding to purchase advanced electronic components.
Importation difficulties for specific parts in Central Africa.
Balancing low power consumption with embedded AI performance.
Combining education, ecology, and technical function into one solution.
Leading a multidisciplinary project while still being full-time students.
Accomplishments that we're proud of
Successfully building a working prototype within an academic environment using limited resources.
Integrating real-world embedded AI (TinyML) into a physical product.
Hosting inter-club competitions between the Mechatronics and Robotics clubs based on this project.
Launching KOYOTECH, our startup, from this first initiative.
Being recognized as a new generation of tech innovators in Cameroon, using technology to serve the environment.
What we learned
That innovation doesn't depend on resources but on vision.
How to collaborate across disciplines (electronics, mechanical, computer engineering).
How to embed AI and IoT into physical systems effectively.
How to present and pitch our ideas through demos, competitions, and grant applications.
What's next for Smart Eco mobile Robot
Complete the version 2.0 with a more robust frame and improved functionality.
Develop a mobile app for real-time monitoring and data logging.
Build partnerships with NGOs, schools, and agritech organizations.
Launch a local mini-manufacturing phase based on pre-orders.
Expand to other African countries and join regional tech incubators.
