Our project goal is to create a motorized longboard that can be controlled using a RC controller-like joystick that will tell the longboard to go forward or go backwards. The controller will be designed to be used in one hand. It will use an Arduino and controllers to control the motors. The board will incorporate regenerative braking that reverts kinetic energy back into usable power for the lithium battery, a DC brushless motor capable of turning both ways, and a pressure sensitive kill switch that turns off the motor when a rider is not detected. Another unique aspect of our board is that it will use sensors or an active drive that will aid in turning by turning down the PWM or by speeding up the outer wheel and slowing down the inner wheel once a turn is identified.

Featured Project

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.

Hardware

• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
