This project is based off of the two microphone probe presented by Professor Swenson and Dr. White. Our plan is to work closely with them at CERL to build a display unit to work with this two microphone probe. This unit will be complete with a GUI, user controls, and two to three BNC connectors for analog microphone input (whether it be two or three microphone probes). We also want to add features in this unit that are capable of: calibrating individual microphone probes, measuring acoustic pressure and particle velocity (the vibration of the particles). The underlying framework of this unit will be designed such that extra user defined features may be added easily. This allows for modularity in our project in such a way that we may also keep adding different measurement features, such as acoustic surface impedance measurement or acoustic surface reflection coefficient measurement. This modularity will also allow Professor Swenson or Dr. White to add on their own functions for their own purposes or for future senior design acoustic projects dealing with this two microphone probe.

Amphibious Spherical Explorer

Featured Project

The amphibious spherical explorer (ASE) is a spherical robot for home monitoring, outdoor adventure or hazardous environment surveillance. Due to the unique shape of the robot, ASE can travel across land, dessert, swamp or even water by itself, or be casted by other devices (e.g. slingshot) to the mission area. ASE has a motion-sensing system based on Inertial Measurement Unit (IMU) and rotary magnetic encoder, which allows the internal controller to adjust its speed and attitude properly. The well-designed control system makes the robot free of visible wobbliness when it is taking actions like acceleration, deceleration, turning and rest. ASE is also a platform for research on control system design. The parameters of the internal controller can be assigned by an external control panel in computer based on MATLAB Graphic User Interface (GUI) which communicates with the robot via a WiFi network generated by the robot. The response of the robot can be recorded and sent back to the control panel for further analysis. This project is completely open-sourced. People who are interested in the robot can continue this project for more interesting features, such as adding camera for real-time surveillance, or controller design based on machine learning.
