Final Demo :: ECE 445 - Senior Design Laboratory

Final Demo

Description

The Final Demo is the single most important measure (and assignment) for the success of your project. The evaluation is holistic, focused on whether your project is completed, well-designed, reliable, and usable. You will demo your project to your professor, at least one TA, and a few peer reviewers. Other guests (e.g. alumni, high school students, sponsors, or other department affiliates) may also be present.

Requirements and Grading

Students must be able to demonstrate the full functionality of their project by proving that all the requirements in their Requirements and Verification (RV) table are met. Students must bring a printed out version of their block diagram, high level requirements, and RV table. Credit will not be given for feature which cannot be demonstrated.

For tests that are lengthy or require equipment not available at the time of demo, students should have their lab notebooks or printouts ready to show testing data. For any portion of the project which does not function as specified, students should have hypotehses (and supporting evidence) of what is causing the problem. If your demo needs to happen somewhere that is not the Senior Design Lab, you must communicate this with your TA!

The design team should be ready to justify design decisions and discuss any technical aspect of the project or its performance (not just one's own responsibilities). Quantitative results are expected wherever applicable. The demo grade depends on the following general areas: See the Demo Grading Rubric for specific details, but in general, show the following:

  1. Completion: The project has been entirely completed.
  2. Integration: The project is well-integrated, looking more like a final product than a prototype.
  3. Performance: Performance is completely verified, and operation is reliable.
  4. Understanding: Everyone on the project team must must be able to demonstrate understanding of his/her technical work and show that all members have contributed significantly.
  5. Polish & Attention to Detail: The project is well-polished with the user in mind. Good attention to detail is afforded to useability, presentation, and packaging.

 

Submission and Deadlines

Signing-up for a demo time is handled through the PACE system. Again, remember to sign up for a peer review as well.

Automatic Water Bottle Filler

Featured Project

# Automatic Water Bottle Filler

Team Members:

- Priyank Jain (priyank3)

- Abby Mohan (ammohan2)

- Jakub Migus (jmigus2)

# Problem

In normal liquid dispensing and water bottle filling systems, the process requires the user’s attention and constant manual activation of the device. This may require the holding of a button, the action of pushing the bottle against a sensor for a specific amount of time, or holding the bottle in front of a sensor until it is full. If the user gets distracted or is unable to provide that attention (blindness or lack of motor function), liquid may spill or the bottle may not be filled enough.

# Solution

Our goal with this project is to make an automatic water bottle filling station. Our device senses when a water bottle is placed underneath it, begins filling the bottle with water once a start button is pressed, determines when the bottle is full and shuts off automatically. After placing the bottle on a platform and pressing a button, the user can walk away knowing their bottle will be filled accurately.

# Solution Components

## Sensing Component

This subsystem utilizes multiple sensors including an ultrasonic sensor to measure the water level and a light-based sensor to determine the height of the bottle.

## Control

This subsystem connects the sensors to the water system. It receives data from the sensors, compares the water level height to the height of the water bottle, then decides to either begin, continue, or stop dispensing water.

## Display/Interface System

An LCD display will show instructions for the user and will display simple messages. A few push buttons will be included for manual filling and selection of desired amount of liquid (ex. Half bottle, full bottle)

## Water System

This subsystem utilizes a water tank attached to a pump and tubing, which transport water to the dispenser.

# Criterion for Success

The device…

- detects a water bottle and accurately measures the height

- monitors the water level in the bottle

- stops filling when a desired water level is reached

If there is no bottle/ the bottle is removed, the device stops filling water.
