**Problem**

Modern cauterization tools are blunt instruments, that cannot distinguish the tissue that must be cauterized from nerves that could potentially be damaged in the process.


**Solution**

Nuerogaurd aims to use low frequency nerve stimulation for nerve identification with high frequency cautery to create a safer surgical tool.

**Sub Systems**

High voltage step down
PWM Input
Remote Sensing and Digital Signal Processing

**High Voltage System**
The Aim of this project is to integrate into current Hospital electronics. The input for the Power System will be 2000V DC, which must be stepped down to 5V DC on the output. The output then must feed a large capacitor that feeds into a power mosfet, which will drive the current pulses for nerve stimulation.

**PWM**

The PWM driver circuitry must take inputs from the remote sensing and drives the power mosfet correctly.

This project will receive support from medical students as well as ECE faculty. I have attached the abstract to this post that better outlines the aims of the electronics for this project.

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.
