I am a member of the U of I Rowing team and an issue we often have is an inability to see our output on the water. When we row indoors the machines give us real time feedback on our output and let us know if we’re on track.I would like to develop a device that would take the force output of the oar on water and relay this information to the users phone.

While devices do exist that track the distance traveled and pace of the boat, these readings are based only off GPS. While useful, this does not solve the problem of finding out individuals output in a boat with more then one person.

The oar passes through an oar lock prior to going into the water. All of the force that moves the boat forward is applied at the pivot point of the oar lock. I figured placing some kind of pressure sensor in-between the oar and the lock would capture the input force.

As for other sensors our group has discussed including gyroscopes to capture the cadence of the boat and a gps unit to track distance and speed.

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
