Additional Projects:



  1. Fast Traversing Autonomous Rover for Mars Sample Collection

    Sponsor: NASA

    Synopsis: The objective of this work is to develop and experimentally validate key technologies needed for autonomous rover traversing on Mars analog terrains

    Contribution: My primary contribution is through the development of state estimation and navigation software



  2. Precision Pollination Robot

    Sponsor: National Robotics Initiative

    Synopsis: The objective of this work is to develop and experimentally validate the effectiveness of a robot to pollinate brambles in a greenhouse environment

    Contribution: My primary contribution is through the development of state estimation and navigation software. Below is an example of our robotic platform performing real-time SLAM in a structured environment --- one similar to a greenhouse.




  3. Sample Return Robot Centennial Challenge

    Sponsor: NASA

    Synopsis: The objective of this work was to design and implemented an autonomous rover with the capability to locate and retrieve specific sample types from various locations over a wide and varied terrain and return those samples to a designated zone in a reasonable amount of time without using Earth based technologies.

    Contribution: My primary contribution for the first year of the project was through the development and testing of algorithms to detect, classify, and track potential objects of interest.
