Individual Progress Report

Description

The Individual Progress Report (IPR) is a chance to put your contributions to the team's progress in writing. The report will discuss not only the components and subsystems you have personally been responsible for, but what components you have helped work on as well. It is important to talk about the relation between your work and your teammates' work as well.

Requirements and Grading

This report should be 5-12 pages of your own work. This means that you cannot take paragraphs/text from your Design Review document, since that was a collaborative effort. The IPR Grading Rubric describes what we look for in grading this assignment. The requirements are expanded on below:

  1. General: Concise writing is encouraged, but it is important that all pertinent information is conveyed. All figures should be labeled and formatted consistently.
  2. Formatting: Please refer to the Final Report Guidelines for general writing guidelines, since the format of this report should be very similar to that of the final report. Note that each component of the Final Report may be tailored to the parts of the project the individual has been active in.
  3. Introduction: First, discuss what portion of the system you have been active in designing connects to which portion of a different subsystem, and how these interact to complete an overall objective. Then discuss what you have accomplished, what you are currently working on, and what you still have left to do.
  4. Design: Discuss the design work you have done so far. It is expected that you have done calculations and/or found relevant equations, created circuits for your parts of the project, and simulated / drawn schematics for your parts. You may have already, at a high level, discussed how your part fits into the rest of the project, but you should expand on the technical details and interface between your module(s) and the other modules of the project.
  5. Verification: Testing and verification is also very important. Make sure you describe each test that was performed and its procedure in detail, and give quantitative, meaningful results. Also describe tests that have yet to be performed. We should be convinced that if all your tests will pass, your part of the project will work.
  6. Conclusion: Discuss a plan and timeline for completing your responsibilities and your project as a whole. Also explain the ethical considerations of your project by consulting the IEEE Code of Ethics, ACM Code of Ethics, or another relevant Code of Ethics.
  7. Citations: You need citations. Cite sources for equations, Application Notes you referenced in your design, and any literature you used to help design or verify your work. If you checked something from another course's lecture slides, Google'd for things related to your project, or anything similar, then you have something you need to cite. At the very least, since you have talked about the ethical considerations of your project as it relates to a published code of ethics (e.g., IEEE or ACM), you should cite those!

Submission and Deadlines

The IPR should be submitted on canvas in PDF format by the deadline listed on the Course Calendar.

Autonomous Sailboat

Featured Project

# Autonomous Sailboat

Team Members:

- Riley Baker (rileymb3)

- Lorenzo Pérez (lr12)

- Arthur Liang (chianl2)

# Problem

WRSC (World Robotic Sailing Championship) is an autonomous sailing competition that aims at stimulating the development of autonomous marine robotics. In order to make autonomous sailing more accessible, some scholars have created a generic educational design. However, these models utilize expensive and scarce autopilot systems such as the Pixhawk Flight controller.

# Solution

The goal of this project is to make an affordable, user- friendly RC sailboat that can be used as a means of learning autonomous sailing on a smaller scale. The Autonomous Sailboat will have dual mode capability, allowing the operator to switch from manual to autonomous mode where the boat will maintain its current compass heading. The boat will transmit its sensor data back to base where the operator can use it to better the autonomous mode capability and keep track of the boat’s position in the water. Amateur sailors will benefit from the “return to base” functionality provided by the autonomous system.

# Solution Components

## On-board

### Sensors

Pixhawk - Connect GPS and compass sensors to microcontroller that allows for a stable state system within the autonomous mode. A shaft decoder that serves as a wind vane sensor that we plan to attach to the head of the mast to detect wind direction and speed. A compass/accelerometer sensor and GPS to detect the position of the boat and direction of travel.

### Actuators

2 servos - one winch servo that controls the orientation of the mainsail and one that controls that orientation of the rudder

### Communication devices

5 channel 2.4 GHz receiver - A receiver that will be used to select autonomous or manual mode and will trigger orders when in manual mode.

5 channel 2.4 GHz transmitter - A transmitter that will have the ability to switch between autonomous and manual mode. It will also transfer servos movements when in manual mode.

### Power

LiPo battery

## Ground control

Microcontroller - A microcontroller that records sensor output and servo settings for radio control and autonomous modes. Software on microcontroller processes the sensor input and determines the optimum rudder and sail winch servo settings needed to maintain a prescribed course for the given wind direction.

# Criterion For Success

1. Implement dual mode capability

2. Boat can maintain a given compass heading after being switched to autonomous mode and incorporates a “return to base” feature that returns the sailboat back to its starting position

3. Boat can record and transmit servo, sensor, and position data back to base
