About

Alexandre Bessa dos Santos is a researcher at the intersection of robotics and photonics, whose work advances both autonomous aerial systems and novel sensing technologies. His primary research areas include unmanned aerial vehicle (UAV) control, robotic manipulation, and fiber optic sensing. Santos made a significant contribution to drone technology with his 2017 paper on autonomous quadrotor positioning for surveillance, which has accumulated 13 citations by addressing the logistical challenges of monitoring vast, difficult-to-access environments. This work highlights the economic advantages of robotic platforms over traditional in-loco monitoring teams. In a more recent and innovative direction, Santos developed a two-dimensional force sensor using a single long-period fiber grating (LPG) for touch applications. This 2020 study, though early in its citation impact with 2 citations, introduces a novel method for robotic manipulators to achieve precise grasping control by measuring lateral compression-induced birefringence. Santos’s research demonstrates a unique ability to bridge mechanical engineering and optical physics, creating practical solutions for both autonomous flight and tactile sensing in robotics.
