Hello! My name is Rakesh, and I am currently a Ph.D. student in Robotics at the Oregon State University Robotic Decision Making Laboratory, under the guidance of Dr. Geoffrey A. Hollinger. I conduct research focused on improving the long-term autonomy of autonomous underwater vehicles (AUVs) in dynamic marine environments. My work includes developing capabilities for autonomous underwater docking, incorporating wave and current models into control frameworks, and facilitating real-time 3D reconstruction of free-floating objects to enhance obstacle avoidance strategies. Overall, my research interests lie at the intersection of perception, motion planning, and control.
Previously I worked as a Project Associate at Indian Institute of Technology - Madras, under the guidance of Dr. P.V. Manivannan. I received my B.E. in Electronics and Communications Engineering from Anna University in May 2019.
Contributed to the migration of Project DAVE, an underwater robotics simulator, to ROS 2 Jazzy and Gazebo Harmonic, including the migration of launch files, robot models, and sensor plugins, as well as maintaining documentation. [blog] [docs] [code]
Developed extensions for autonomous ROV operations and improved ArduSub capabilities. Also worked on the integration of DVL, GPS, and an imaging sonar sensor.
Developed a navigation stack for multi-robot coordination in a kitchen environment. Designed and implemented a high-level finite state machine using ROS. Integrated RTAB-Map for localization and mapping of the environment.
Worked on visual-servoing and trajectory optimization of a 2 DOF industrial robot manipulator. Implemented computed-torque control for smooth and precise control of the manipulator.
Worked on perception and motion planning of aerial robots for various applications, such as warehouse inventory management, drone show and wind turbine inspection.
