The interaction between a liquid drop and a solid surface is governed by the surface’s hydrophilicity and geometry, which influence the contact angle and, consequently, the curvature of the liquid–air interface. This study focuses on the shape of the drop interface when a gap or channel is formed between two surfaces on which the drop is placed.
To achieve this, we are designing and constructing an experimental setup capable of studying the curvature of the drop interface under controlled conditions. This setup features a precision mechanical system that enables micrometric control of the separation distance between the surfaces. It is integrated with an imaging and analysis system to accurately measure the drop’s shape and contact angles.

In recent years, autonomous robotics has seen significant progress, especially in Agriculture and Industry. This project presents a compact, affordable autonomous robot designed to follow predefined routes without human input. Equipped with sensors for obstacle detection and a camera for real-time video, it enables efficient environmental monitoring and documentation. The aim is to offer a low-cost solution in lieu of complex, expensive systems that limit accessibility. Automating routine tasks, like patrolling and measuring environmental conditions, helps improve efficiency and reduces human risk. This robot can serve in agricultural fields, industrial logistics, and emergency situations. Eventually, features like a lifting mechanism for the camera or other tools will be added. This system paves the way for future autonomous innovations.
Keywords: autonomous robot, environmental monitoring, low-cost robotics, navigation system, obstacle avoidance, real-time video
