Daniel’s Status Report for April 25
This week, I spent most of my time trying to record sample throw estimation data with a basic measurement setup and our existing simulation. I discovered that with successive trials, the IMUs began to report increasingly poor data. Thus, what would begin as clear parabolic data would eventually become something Read more…

Team Status Report for April 25
This week, our team shifted it’s focus to gathering as much data as possible, making steady improvements, and putting together a presentation for Luca to deliver next week. Our device is functioning, but not without it’s hitches. Dan spent the majority of this week recording trial data and trying to Read more…

Daniel’s Status Report for April 18
This week, I made a significant stride in binging the project closer to completion. My first task this week was to add in the second IMU from which we tell the release point. I was having trouble getting the AD0 pin to change the address of one of the IMUs, Read more…

Daniel’s Status Update for April 11
This week, the main new issue for me to conquer was the addition of the Particle Photon. Although we’re still having some trouble getting the hardware to work on Luca’s end, I’ve been able to make some good progress with respect to getting the Photon to wirelessly transmit data. I Read more…

Team Status Update for April 4
This week, team B4 explored other options for 3D IMU positioning as Hana continued parallel work on the Processing simulation. On the 3D positioning side, Daniel looked into using Madgwick’s AHRS algorithm in order to determine IMU rotation and remove the earth’s gravity from 3D readings. Using this algorithm in Read more…

Daniel’s Status Report for April 4
This was an extremely involved week for me as I tried to improve the functionality of our Kalman filter. Upon running numerous tests on 2D data of the IMU moving across my desk, I couldn’t seem to entirely remove the traces of drift and gravitational error present in my data. Read more…

Daniel’s Status Report for March 28
This week, my focus was on implementing the accelerometer portion of the Kalman filter and debugging issues related to bias drift. Right now, I’m working on getting the Kalman filter to report a steady absence of movement when the IMU sits still on my desk. I’m getting close but I Read more…

Team Status Update for March 28
This week, our team updated our plans and Gantt chart for the remainder of the semester and began implementing the Kalman filter head on. Immediately running into issues related to bias drift, we are currently trying to resolve these issues with calibration and adjusting the Kalman filter accordingly. We are Read more…
