Final Project

Objectives

---

Your goal in this project is to explore a topic in robotics that is interesting to you and your team. This open-ended project is an opportunity to be creative and ambitions and we are excited to see what you will accomplish!

Learning Goals

• Defining and working on an open-ended project
• Learning about a new robotics algorithm in greater depth through its application in this project
• Working on a robotics project from start (coming up with a good idea) to finish (implementing your idea on a real robot)

Teaming & Logistics

For this project, your team should consist of 2-4 members. You can work with prior partners from the previous 2 projects. Like the prior two projects, we do ask that your project team all attend the same lab section for the next 3 weeks.

Deliverables

---

Project Pitches

Develop and submit 1-2 final project pitches and put them in this Google Doc. In that Google Doc, you can also find instructions and example project pitches.

Project Proposal

Your project proposal should include:

• Your team name
• A list of your team members
• A link to your team's Github repo
• Motivation (2-3 sentences): Why is your team interested in pursuing this project?
• Main Components (1 paragraph): What are the main topics covered in your project? What robotics algorithm(s) will you be exploring in your project? Are there any other main components to your project?
• Final Product (1 bullet point per deliverable level, 2-3 sentences per bullet point): For each of the following, what would success look like:
  1. a minimum viable product (MVP)
  2. a solid end result
  3. an end result that you would consider to be a "stretch" (e.g., "it would be above and beyond if we could...")
• Timeline: Provide a rough draft timeline for the major milestones of your project
• Resources: Describe what materials you plan to use (e.g., additional sensors, objects for the robot to pick up, a maze environment) as well as details about the turtlebot(s) that you plan to use (how many turtlebots, whether or not you want the OpenManipulator arm(s) attached).
• [Optional] Budget: If you would like additional materials for your project, please develop a budget with estimated costs and links for the components you are requesting.
• Risks (2-3 sentences): What do you see as the largest risks to your success in this project?

Your project proposal should be placed in a Google Drive folder your team creates for its deliverables. When you're ready to turn in your project proposal:

• Give all the members of the teaching team read & comment access to the Google Drive folder (sarahsebo@uchicago.edu, tewodrosayalew@uchicago.edu, tinghan@uchicago.edu)
• DM all of the teaching team the link to your Google Drive folder on Slack

Presentations

All of your presentations should be uploaded to your team's Google Drive folder before the class when you're presenting.

• Midway Presentation: This first presentation is meant to tell the class about your project idea and showcase your initial work towards achieving your project goals. This presentation should include the following slides:
  • 1 slide: Team name & team members
  • 1 slide: Project topic (please make changes to reflect any changes in the project topic since the initial idea presentation)
  • 1 slide: 2-3 overarching goals that your team wants to accomplish through this project
  • For each major component of your project (e.g., the Q-learning project could be organized into three components 1) perception, 2) robot navigation & arm movement, and 3) the q-learning algorithm):
    • 1 slide: Description of the component
    • 1 slide: Your group's current progress on this component (gifs, screenshots, and/or videos encouraged) -- it's ok if you haven't started on a component yet
  All team members are expected to speak during this midpoint presentation. Also, your presentation should take between 4 and 6 minutes (we will cut you off at 6 minutes).
• Final Presentation
  • 1 slide: Team name & team members
  • 1 slide: Project topic
  • 1 slide: Your project goals
  • For each major component of your project:
    • 1 slide: Description of the component
    • 1 slide: How you completed this component (gifs, screenshots, and/or videos encouraged)
  • 1 slide: Demo - play a video recording for your demo - your demo should clearly exhibit all of the functionality and features of your project
  • 1 slide: Challenges - what were the 2-3 main challenges you faced and how did you overcome them
  • 1 slide: Future work - if you had 2-3 more weeks, what additions/changes would you make to improve your project
  All team members are expected to speak during this final presentation. Your final presentation should take between 7 and 8 minutes (we will cut you off at 8 minutes).

Code

You'll organize your code into one Github repo.

Writeup

Like in the previous projects, your Github README will serve as your project writeup. Your writeup should include the following:

• Project Description: Describe the goal of your project, why it's interesting, what you were able to make your robot do, and what the main components of your project are and how they fit together - please include diagrams and gifs when appropriate
• System Architecture: Describe in detail the robotics algorithm you implemented and each major component of your project, highlight what pieces of code contribute to these main components
• ROS Node Diagram: Please include a visual diagram representing all of the ROS nodes, ROS topics, and publisher/subscriber connections present in your final project.
• Execution: Describe how to run your code, e.g., step-by-step instructions on what commands to run in each terminal window to execute your project code.
• Challenges, Future Work, and Takeaways: These should take a similar form and structure to how you approached these in the previous projects (1 paragraph each for the challenges and future work and a few bullet points for takeaways)

Demo

Each team will provide a live demo of their project during the finals period time slot. Your demo should clearly exhibit all of the functionality and features of your project. Because live demos can sometimes go awry, we recommend having a backup demo video.

Grading

• 5% Project proposal
• 50% Code (scope, functionality, design, documentation)
• 10% Writeup
• 10% Presentations
• 5% Demo (as shown on Github README & live demo)
• 20% Individual Contribution to the Team

Choosing a Project Topic

---

Requirements

• Your project must involve a robot and be focused on a robotics problem.
• Your project should involve learning about a robotics algorithm that no one on your team is an expert at. A central goal of this project is to either 1) learn about a new robotics algorithm or 2) expand a robotics algorithm beyond what we discussed and applied earlier in the course, and then apply this algorithm within the context of your project. Examples of robotics algorithms you could explore in the final project include:
  • Inverse kinematics (e.g., programming your own inverse kinematics solver for the turtlebot)
  • A* (e.g., programming your own A* path finding algorithm for the turtlebot)
  • Reinforcement learning beyond Q-learning with MDPs
    • Multi-agent reinforcement learning
    • Deep reinforcement learning
    • Applying reinforcement learning to contexts with larger state spaces and with more complex dynamics
  • Computer vision algorithms (e.g., a gesture recognition algorithm, a face-detection algorithm)
  • Genetic algorithms
• Your project work should be accomplished on 1 or more physical Turtlebot3 robot(s).

Additional Resources

The final project offers you the opportunity to go beyond what we've done in class thus far in several ways:

• You may use more than one turtlebot for your project. Given that our class doesn't have an unlimited supply of turtlebots, please only use as many as necessary to accomplish the main goals of your project.
• You may use turtlebot(s) either with the OpenManipulator arm or without. If you want to use the turtlebots without the arm, please let the teaching team know so we can remove the arm and reset the software on the bot(s).
• You may use the Gazebo simulator, however, your final demo must include a component on a physical turtlebot. Similar to how we could use phantom_robot_movement.py in Gazebo to train our Q-learning model for the Q-learning project, you are more than welcome to utilize Gazebo for this project. Again, as stated here, the final demo must involve a physical turtlebot.
• You may use any of the materials we've already used in the class. This includes the maze, the bricks with velcro, the colored paper towel tubes, etc.
• You may augment your turtlebot with additional sensors and components beyond those it's already equipped with. We have on hand these extra components that you are welcome to use for your final projects:
  • TS-10 Touch Sensors: These sensors can be mounted on the Turtlebot as a bumper to detect impact with objects. There is information on how to incorporate these sensors with the turtelbot on this page.
    
    
    

    
    
    
  • LEDs: We have this 56 pack of white, red, yellow, green, blue, and orange pre-wired LEDs. A guide for how to incorporate them with the Turtlebot can be found on this page.
    
    
    
• You may 3D print objects. Feel free to 3D print components to augment your turtlebot or for your turtlebot to pick up. We encourage you to use the 3D printers in the MADD center.
• You may request for us to purchase extra components for your project. In addition to the materials we already have on hand, you can also ask us to purchase sensors, components, and/or materials for your project. If you want us to purchase materials for your project, you must list the items you want and include a project budget in your project proposal. This will ensure that we have enough time to get you the parts you need for your project.

Example Final Projects

Please keep in mind that some of these project examples come from when the class was taught on Zoom and entirely in simulation due to COVID-19.
