Mobile Robotics (CSE483) Linear Control System (ECE451) Intro to Robotics: Mechanics and Control (ECE452) RESEARCH PROJECTS Vision based exploration Abstract: At present I am working on monocular camera based exploration system for ground robots and micro aerial vehicles. I use PTAM for interacting with environment. The objective is to densify sparse map pointcloud and improve the efficiency of PTAM by introducing a planning algorithm to dictate camera trajectory. The challenge to overcome is twofold, PTAM only provides sparse map information which in insufficient for exploration, thus some other clues like planar information are needed to generate a denser map. Secondly, the efficiency of PTAM depends on movement of camera and is very prone to rapid rotational motion, thus a planning algorithm is required to dictate trajectory of camera so that algorithm works efficiently for a large scale environment. Status: In Progress. Utilities: ROS, C++, Matlab Coordinated UGV-MAV Exploration for 2D Augmented Mapping Abstract:The objective of this project was to explore an unknown area using heterogeneous agents(UGV and MAV) and build a 2D augmented map. The laser sensor on ground robot builds 2D ground map and using monocular camera on MAV a pointcloud for elevated area is generated. The exploration strategy was formulated an Integer Programming problem. Using extensive simulation it was the shown that the proposed method performs better than previous method in multiple scenarios. This work was presented in IROS,2013. Status:Completed. Utilities:ROS, OpenCV, OpenSceneGraph,PCL,C++ Distributed and Asynchronous multi robot exploration using Max-Sum Abstract:The objective of this project was to exploit the distributive and asynchronous nature of a multi robot system for exploration. The problem of task/goal assignment is represented as factor graphs and is solved using Max-Sum algorithm. This work is under review for ICRA,2014. Status:Completed. Utilities:ROS, OpenCV, OpenSceneGraph,PCL,C++ Floor segmentation using monocular camera Abstract:The objective of this project is segment out the from a sequence of camera. Using homography and optical flow, set of sparse features lying on floor are tracked and using color segmentation image is divided into multiple segments. The tracked features are then used for selecting segments lying on floor. This work was published in ICVGIP,2012 Status:Completed.
