About Me

     Howdy! My name is Diego Ruvalcaba, I am an Engineering Honors student and the proudest member of the Fightin' Texas Aggie class of 2020! I am doing Undergraduate Research with Parasol Labs working on Motion Planning. More specifically, I am working creating Workplace Skeleton Tools for the user to be able to see the skeleton in our visual software called VIZMO and be able to edit it and save it. Eventually we will be able to use information from each vertex and edge such as clearance from obstacles to help optimize the motion planner. I'm working with current PhD Student, Mukulika Ghosh, at Texas A&M University who works with Dr. Amato as well on Computational Geometry.

I am from Cypress, Texas and I graduated from Cypress Ranch High School in 2016. I started programming in High School and after a while it began to grow on me. I started to do small projects on the side and eventually I joined the UIL team for my High School. Eventually, I realized that this is what I wanted to do for my career and so I decided to come to Texas A&M to hopefully get a Undergraduate degree in Computer Science with a specialization in Artificial Intelligence and Machine Learning. I first gained interest in Artificial Intelligence when I created a Connect Four player that could play against you. I really enjoyed giving it algorithms that allowed it to have basic and advanced Connect Four strategy and even be able to predict moves.

Research Plan 2017

Workspace Skeleton Tools


Description

Motion Planning is the problem of finding a collision free path for a moveable object from a starting to an end position. Its applications can range from robots, minimally invasive surgical planning, molecule binding and folding and many more. The space that occupies the robot and all of its obstacles is known as the workspace.

Various data structures are put into place to store information about the workspace. An example data structure that does this is the workplace skeleton. A workplace skeleton is an embedded graph in an obstacle or free environment.

My peers and I will be conducting research on how the different properties of the workspace can be added to the skeleton to better motion planning. We will learn how the workplace skeleton works as well as how we can add information to it from the workspace. We will run tests to see how this added information performs in different motion planning problems. Finally, we will use tools to visualize the workspace skeleton and its properties, color its components and animate its construction. All of this would help to better understand these important data structures and how they are used in motion planning algorithms.

Sampling Types for PRM

Purpose

I chose motion planning in general because it had a lot of very interesting topics that I would like to very much further in my knowledge. I want to specialize in Artificial Intelligence and Machine Learning and Dr. Amato and Dr. Shawna believed that motion planning was a great fit. I believe that this research experience will be good for me to use as a strong foundation into computer science applications. I think motion planning is a very interesting problem and I am very excited to learn more about it.

Medial Axis Skeleton

Project Goals and Implications

The goals for this project is to create a way to store information about the workspace to use in motion planning problems. With the creation of a workspace skeleton we can easily store and use information inherent to the workspace. The visualization of the workplace skeleton will allow the users to see how the skeleton works as it solves motion planning problems. This will allow for users to analyze and inspect how the workspace skeleton works.



Personal Goals

This project will allow me to familiarize myself with Computer Science practices and concepts in Motion Planning. I will learn how to conduct research with independent experiments and how to present my results. I will develop skills like, C++ coding skills inside an existing code base, Engineering practices for working in a group, data structures and algorithm design, the scientific approach, writing technically, and preparing and present research work.



First, I need to learn the basics of motion planning, data structures and visualization by reading a couple of research papers about the topics. Secondly, I need to familiarize myself with the Parasol Lab’s Motion Planning Library (PMPL) and Parasol Lab’s Visualization software (VIZMO). Then, I need to create a way to store and retrieve information with the existing workspace skeleton. Once that is done, I need to translate the skeleton model from PMPL to the visual software (VIZMO). Next, I will create additional features like the ability to color components or animate its construction. Only then can I begin testing and analyzing different information about the workspace. Finally, I will document the workplace skeleton’s design into a paper and prepare and present a poster at the end.


Method & Materials

I will be using the Parasol Lab’s Motion Planning Library (PMPL) as well as the visual software, VIZMO, and C++ programing to help me with my workplace skeleton.



Work Schedule

I am expected to work 8 hours each day, not including breaks, from Monday through Friday. I may also work outside of the lab to further my project to ensure I meet the deadlines asked of me.

It was exciting to be able to actually use code and document it so that it can hopefully be checked in someday. We also build an entire new class that allows us to store properties of vertices and edges. With that new class we build some get and set functions so the user can add vertices or edges as well as access properties of them given their descriptor. On top of that I made a very nice website that allows the user to contact me and view my weekly reports in an interesting manner.
