About
A research-oriented mechanical and mechatronics profile spanning robotics, CAD/CAE, simulation, additive manufacturing, and startup execution.
I am a Mechanical and Mechatronics Engineer currently pursuing an M.Sc. in Mechatronics and Cyber-Physical Systems at Deggendorf Institute of Technology in Germany. My work focuses on robotics, autonomous navigation, control systems, CAD/CAE simulation, additive manufacturing, and practical engineering product development.
My current research explores precise localization and autonomous navigation for mobile robots, including full-state feedback stabilization using Linear Quadratic Regulation and simulation workflows in MATLAB/Simulink, ROS, and Gazebo.
Before my Master's studies, I completed a Bachelor's in Mechanical Engineering from Pashchimanchal Campus, Institute of Engineering, Tribhuvan University, Nepal, graduating with First Division. I have worked on UAV development, electric vehicle design, biomedical device improvement, renewable energy research, and engineering education.
I am also the Founder and Managing Director of GadiDokan Pvt. Ltd., where I combine mechanical engineering, repair operations, procurement, and digital systems to build practical vehicle-focused services.
