## Problem:
As EE students, most of us have stored many electronic components such as resistors, capacitors and MOSFETs. Traditionally, we would store these components in storage organizers, a huge cabinet with many transparent plastic drawers. A small organizer may only have as few as 20 drawers. However, a larger one can have up to a hundred organizers. A big problem is that people usually cannot immediately locate the components they want. They have to look into the transparent boxes or at the tags one by one, wasting lot of time.

## Solution Overview:
We propose a solution of this problem by creating a logger with indicators for people to better store and find components. It would also consist of mechanical designs to push the drawers out from the back. People would use the logger to either assign a certain drawer to a certain component or command the automated stick to push out the drawer with the component they need. The logger would have a simple LCD screen and buttons (with labels of 0 to 9 and r, c, l, ic, value, number, enter, eject and clean). User would be able to log new components and find logged components using the screen and the button. To find a certain component, user would use the buttons to specify the component they want. For example, if user types r, 0603, value and 200 and presses enter, the indicator (a LED) of the drawer which user registered before for this component would be lit. If the user press eject button, the specified drawer would be pushed out from the back.

## Solution Components:
*Logger subsystem* The logger would be composed of an LCD screen and buttons mentioned in the overview. The LCD screen will show the menu for user to interact with the system using buttons so that new components are logged, and old components are located. All the required programs would be instantiated in an ARM chip.
*Mechanical pusher subsystem* The pusher would be located at the back of the organizer box. It would push out a certain drawer specified by the user. The pusher would be a simple structure resembling a robotic arm with two degree of freedom for reaching all drawers.
*Indicator array subsystem* There would be a 2D array of LEDs to show boxes specified by user.
*Power subsystem* The power subsystem would be composed of some regulators and MOSs to drive both the digital circuit including logger subsystem and ARM chip as well as the Mechanical pusher subsystem.

## Criterion for Success:
Users are able to register new components into the system
Users are able to locate components with buttons, LCD screen and indicators
Mechanical structure would be able to push out any drawers

Featured Project

**Problem:** When working out at home, without a trainer, it’s hard to maintain good form. Working out without good form over time can lead to injury and strain.

**Solution:** A mat to use during at-home workouts that will give feedback on your form while you're performing a variety of bodyweight exercises (multiple pushup variations, squats, lunges,) by analyzing pressure distributions and placement.

**Solution Components:**

**Subsystem 1: Mat**

- This will be built using Velostat.

- The mat will receive pressure inputs from the user.

- Velostat is able to measure pressure because it is a piezoresistive material and the more it is compressed the lower the resistance becomes. By tracking pressure distribution it will be able to analyze certain aspects of the form and provide feedback.

- Additionally, it can assist in tracking reps for certain exercises.

- The mat would also use an ultrasonic range sensor. This would be used to track reps for exercises, such as pushups and squats, where the pressure placement on the mat may not change making it difficult for the pressure sensors to track.

- The mat will not be big enough to put both feet and hands on it. Instead when you are doing pushups you would just be putting your hands on it

**Subsystem 2: Power**

- Use a portable battery back to power the mat and data transmitter subsystems.

**Subsystem 3: Data transmitter**

- Information collected from the pressure sensors in the mat will be sent to the mobile app via Bluetooth. The data will be sent to the user’s phone so that we can help the user see if the exercise is being performed safely and correctly.

**Subsystem 4: Mobile App**

- When the user first gets the mat they will be asked to perform all the supported exercises and put it their height and weight in order to calibrate the mat.

- This is where the user would build their circuit of exercises and see feedback on their performance.

- How pressure will indicate good/bad form: in the case of squats, there would be two nonzero pressure readings and if the readings are not identical then we know the user is putting too much weight on one side. This indicates bad form. We will use similar comparisons for other moves

- The most important functions of this subsystem are to store the calibration data, give the user the ability to look at their performances, build out exercise circuits and set/get reminders to work out

**Criterion for Success**

- User Interface is clear and easy to use.

- Be able to accurately and consistently track the repetitions of each exercise.

- Sensors provide data that is detailed/accurate enough to create beneficial feedback for the user

**Challenges**

- Designing a circuit using velostat will be challenging because there are limited resources available that provide instruction on how to use it.

- We must also design a custom PCB that is able to store the sensor readings and transmit the data to the phone.
