In the framework of this project, which seeks to stimulate public discussion of atmospheric CO₂ levels and the importance of rehabilitating the world’s forests, a series of robotic forest rangers were developed to support reforestation efforts and sustainable forest management. Each robot is assigned a defined role in managing and preserving the forest. Their roles and design language reflect a long process of studying the work of forest rangers and an attempt to gain an in-depth understanding of the needs of the world’s forests.
