Carnegie Mellon ECE Capstone, Spring 2019 – Michael You, Sid Lathar, Benjamin Huang
Ben’s Weekly Update 4/21-4/27
Constructed bike with Mike. Worked on the bus connection between the front sensor cluster and the back sensor cluster of the bicycle, including support for additional sensors if necessary and backup wires.
Wrote better startup code for system which runs a full system test before running, starts up with the Pi, and waits to reconnect to the jacket if unsuccessful.
Made the communication protocols more robust. We were getting issues where the serial interface with the Bluetooth chip on the Arduino was going out of sync. We solved this by using some magic sequences to ensure every message is properly aligned.
Got bicycle clamps to mount the constructed system onto the bicycle.
Got the trainer for demo purposes.
Tested frontal collisions. Ran tests on the mall in front of Doherty Hall. We marked the walking path with distances, set up recording devices, and ran the frontal collision tests to determine both response time and alert lead-time, as well as determining false-positive tests on receding objects.
