Building robots for all terrain all weather applications with swarm behavior.1. Designed custom multi-robot simulation on Gazebo to test up to 10 robots; Integrated Lidar, IMU and Camera plugins2. Implemented and tested differential drive and Ackermann steering for custom robot simulation3. Added autonomous mapping and navigation system by integrating ROS2 Slam ToolBox and ROS2 Nav24. Utilized Redd Shepp motion model and Regulated Pure Pursuit (RPP) controller to increase robot speed by 3x5. Used ROS2 control framework to create custom hardware interface in C++ to send PWM signals to wheel motors6. Integrated Compute Module 4 (CM4), Arduino Uno, Cytron Motor Driver, 24V Motor and Optical Encoder as part of hardware integration task7. Created Mux for controlling multiple robots via Rviz interface; Added functionalities for multiple waypoints, final goal pose and manual control; Tested on a simulation of 4 robots8. Integrated 3D Lidar scan with BEVNet to create 2D cost map for off-road navigation

Pittsburgh, Pennsylvania, United States

Working on MMPUG project - Heterogeneous Multi-Robot Search & Rescue project. 1. Developed a decentralized communication multiplexer using ROS for multi-robot inspection operations, enabling real-time exchange of information; Tested on a system on 7 robots2. Co-Developed “Make Way” behavior to allow collision-free movement of multiple robots in narrow passageways3. Developed Transfer-Control checks preventing inadvertent transfer of robot control among operators4. Developed contingency behavior for robots in case of communication loss with base-station5. Improved AutoCalibration module, extending the functionality to multi-robot multi-operator setup6. Designed interactive GUI for Human Robot Interaction (HRI) using Qt framework, enabling multi robot control7. Performed regular sensor calibration of payload housing RGB/Thermal camera and IMU using Kalibr Toolbox8. Planned and executed field tests for demonstrating technical capabilities to sponsors and stakeholders

1. Reduced defective soap manufacturing by 5% by implementing 5-WHY analysis and Kaizen2. Executed pipeline inspection, resulting in identification of 24 retrofitting defects3. Part of 3 member team responsible for designing & laying out new production line, identifying feasible locations, coordinating with OEMs, and implementing inventory management plans

Braunschweig Area, Germany

Worked on the development of a cold storage station in an assembly line of the learning factory at IWF, TU Braunschweig, Germany as a part of my undergraduate thesis funded by DAAD. Successfully automated the storage station. Main contribution to project are:1. Upgraded autonomous cold storage unit as part of Industry 4.0 research under the JInGEL project2. Implemented PID controller for temperature control; Integrated PLC, sensors, peltier elements and power supply unit3. Integrated pick & place functionality for 3-DoF gripper for storing and extracting workpieces from cold storage unit
