# PROBLEM
In this time of COVID, sanitation is everything. We must make sure ourselves and our belongings are clean in order to help mitigate the spread of COVID. Especially with more companies, buildings, restaurants, and gyms opening up, its easier for the disease to spread. Especially in gyms, people are constantly sharing lockers with their sweaty belongings and clothes, which can easily spread germs.

# SOLUTION OVERVIEW
We propose a self cleaning locker. When the locker detects that nothing is in the locker, it will automatically disinfect the inside of the locker using a disinfectant spray, and then and LED display out the outside will display that the locker is clean and ready to use for the next person.

# SOLUTION COMPONENTS
## Sanitizing Subsystem
We would attach a spray that sprays disinfectant when it senses that the locker is empty. This would be implemented using a pressure sensor to detect if there are things inside the locker. Once there is nothing detected inside the locker, and the locker is closed, then a motor will automatically spray disinfectant throughout the locker.

## LED Display
The LED display will be used to show whether or not the disinfecting process was been initiated, will will display either "Clean" or "In Use". This will communicate with our sanitation subsystem using a PCB that communicates throughout our whole locker / project.

# CRITERION FOR SUCCESS
We want to make sure that when the locker detects that it is empty, it will be able to sanitize the inside of the locker. If there are items within the locker, we don't want our spray to accidentally trigger, making the user's belongings wet / damp.

VoxBox Robo-Drummer

Featured Project

Our group proposes to create robot drummer which would respond to human voice "beatboxing" input, via conventional dynamic microphone, and translate the input into the corresponding drum hit performance. For example, if the human user issues a bass-kick voice sound, the robot will recognize it and strike the bass drum; and likewise for the hi-hat/snare and clap. Our design will minimally cover 3 different drum hit types (bass hit, snare hit, clap hit), and respond with minimal latency.

This would involve amplifying the analog signal (as dynamic mics drive fairly low gain signals), which would be sampled by a dsPIC33F DSP/MCU (or comparable chipset), and processed for trigger event recognition. This entails applying Short-Time Fourier Transform analysis to provide spectral content data to our event detection algorithm (i.e. recognizing the "control" signal from the human user). The MCU functionality of the dsPIC33F would be used for relaying the trigger commands to the actuator circuits controlling the robot.

The robot in question would be small; about the size of ventriloquist dummy. The "drum set" would be scaled accordingly (think pots and pans, like a child would play with). Actuators would likely be based on solenoids, as opposed to motors.

Beyond these minimal capabilities, we would add analog prefiltering of the input audio signal, and amplification of the drum hits, as bonus features if the development and implementation process goes better than expected.
