Daun Bot

Background:

Typically, soil sampling is done manually, which often results in inconsistent data. These inconsistencies lead to inaccurate information such as nutrient levels, heavy metals, etc. limiting farmers' ability to manage their crops effectively.

Our robot will collect composite samples made of smaller soil samples using an auger drill to penetrate the ground, extract the samples, and store them in a designated sample box. Additionally, it will feature multi-terrain wheels powered by four DC motors, allowing it to navigate various terrains with ease. This automation improves accuracy, efficiency, and overall crop management.
