# Problem
Extensive research efforts have been devoted to understanding the complex mechanisms of friction wear to minimize their effects in sliding systems. Improvements in the instruments used to characterize the friction and wear phenomenon are required to enhance the effectiveness of the research method. In this project, our goal is to design and build an experimental platform that evaluates surfaces' frictional behavior will be designed.

# Solution Overview
Our solution is to build a modular friction test platform, which is capable of accurately measuring the friction, wear rate and contact behavior between surfaces of different materials. It will include high precision sensors, controllable condition system and data acquisition system and allows researchers to simulate a variety of different conditions (temperature, loads, velocity)

# Solution Components
## Mechanical Body Systems
The platform will be using a modular design, which allows easier maintenance and transportation. Its body will be able to be fixed on other platforms to reduce errors from vibration or movement.

## High Precision Sensors
The platform will contain four main sensor types:

- Force sensors for constantly detecting the friction force.
- Displacement sensors for monitoring wear and deformation on the platform.
- Temperature sensors for detecting the temperature.
- Velocity sensors for monitoring the velocity of the loads.

## Controllable Condition System
This system will control the conditions of the platform, and it also consists of several parts:

- High precision motor drive system for controlled sliding speeds
- Normal force application unit for applying controlled load on normal direction
- Temperature control module for adjusting the temperature

# Criteria for Success
We will measure our success by examining multiple sample objects’ friction properties on the platform, and check if every component works well. If the results of our examination are near the true properties of samples (error < 5%), we call it success.

Laser Harp MIDI Controller with Musical Articulations

Featured Project

Electronic music concerts usually need eye-catching visual aids to create a certain atmosphere. Laser musical instruments is a great way to do this. We have been thinking of this project for a while and it was ECE445 that made this laser harp come true. The novelty of this project is that the harp-like laser device mainly focuses on playing articulations with laser and sensors, as a true universal MIDI controller, to control timbres that are synthesized or sampled. Articulations include piano/forte, vibrato, tremolo, and portamento. With the help of Professors and TAs, we learned how to pick right the components, design PCB, soldering, and program microcontroller. Those skills are not only useful in this class but also really important to electrical engineers. Also, we learned how to use individual strengths, combined with effective teamwork, in the pursuit of meaningful goals.
