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.

Prosthetic Control Board

Featured Project

Psyonic is a local start-up that has been working on a prosthetic arm with an impressive set of features as well as being affordable. The current iteration of the main hand board is functional, but has limitations in computational power as well as scalability. In lieu of this, Psyonic wishes to switch to a production-ready chip that is an improvement on the current micro controller by utilizing a more modern architecture. During this change a few new features would be added that would improve safety, allow for easier debugging, and fix some issues present in the current implementation. The board is also slated to communicate with several other boards found in the hand. Additionally we are looking at the possibility of improving the longevity of the product with methods such as conformal coating and potting.

Core Functionality:

Replace microcontroller, change connectors, and code software to send control signals to the motor drivers

Tier 1 functions:

Add additional communication interfaces (I2C), and add temperature sensor.

Tier 2 functions:

Setup framework for communication between other boards, and improve board longevity.

Overview of proposed changes by affected area:

Microcontroller/Architecture Change:

Teensy -> Production-ready chip (most likely ARM based, i.e. STM32 family of processors)

Board:

support new microcontroller, adding additional communication interfaces (I2C), change to more robust connector. (will need to design pcb for both main control as well as finger sensors)

Sensor:

Addition of a temperature sensor to provide temperature feedback to the microcontroller.

Software:

change from Arduino IDE to new toolchain. (ARM has various base libraries such as mbed and can be configured for use with eclipse to act as IDE) Lay out framework to allow communication from other boards found in other parts of the arm.
