Pests and diseases remain a major constraint to agricultural productivity in Zimbabwe, causing significant losses and limiting farmers’ income. In greenhouse farming, early detection of infestations is critical to ensure healthy crops and reduce pesticide overuse. This study presents a computer-vision system powered by artificial intelligence (AI) for early identification of ...

Mining operations present hazardous conditions, particularly in post-blast environments where the accumulation of toxic gases poses significant risks to worker safety. This study presents a robotic system designed to autonomously navigate underground mining terrains and detect harmful gases such as methane, carbon monoxide, and carbon dioxide. The robot is built with a rocker-bogie ...
