* Worked on moving computationally heavy operations of the robot like motion planning and image processing onto the cloud.* Worked on Apache Storm and on Python * Used FutureGrid which is a project led by Indiana University and funded by the National Science Foundation (NSF) to develop a high-performance grid test bed that lets scientists collaboratively develop and test innovative approaches to parallel, grid, and cloud computing.* Had to collaborate with 2 other departments i.e. the Computer Vision team and the Cloud Computing team.* Also worked on modularization of the robot's code which was written in Python.

* A general resource reservation framework for cloud computing frameworks while also focusing on bare metal resource provisioning. It is important that resource reservations are supported in a multi-user, multi-project environment. Worked with a team that developed a system in which users will have access to resources based on time slices. The interface to the framework allows access through command line tool, Web interface, as well as a programming API in python. By the end of summer I was able to start and shutdown Virtual machines using this reservation framework successfully. * Was also a mentor to a student who had come to Indiana University for a Summer program from Dillard University New Orleans. I mentored the student on Python and MongoDB for the Cloud computing project.* Technology Used: Flask, Docopts, Python, Openstack-Havana, Rackspace, Vagrant, Chef cookbooks., MongoDB
