About

Bahram Lavi Sefidgari is a robotics researcher whose work focuses on the control, autonomy, and real-world application of quadcopter flying robots. His primary contributions lie at the intersection of adaptive control systems and computer vision, addressing critical challenges in unmanned aerial vehicle (UAV) functionality. His most cited work, "An adaptive neuro PID for controlling the altitude of quadcopter robot" (2013, 38 citations), introduces a novel adaptive PID controller that intelligently tunes its own coefficients to achieve stable altitude control, a fundamental problem in aerial robotics. Building on this, Sefidgari developed vision-based systems for human body detection and tracking using onboard cameras, as detailed in his 2013 papers (7 and 4 citations). These systems enable a quadcopter to autonomously identify and follow a human subject, with applications in security and safety monitoring. Further extending this capability, his 2014 work on auto-landing (3 citations) employs edge detection algorithms to guide a flying robot to a safe landing zone. Collectively, Sefidgari’s research demonstrates a cohesive effort to make quadcopters more intelligent, responsive, and practically useful for surveillance and care tasks.
