Month: April 2019

We got to demo this week, where we got to showcase much of the hardware features. The system is mostly reliable, but needs polishing and actual formal construction, e.g. heat shrink, gluing, printing out cases, soldering, before we can consider the hardware components done. We are waiting on the last 2 LIDARs to come in so we can mount everything onto the bike.

We are a little behind on the mobile app, but the software should be easy to finish once we fix some bugs there.

Monday:

• Designed protoboard layout for the bike circuit

Tuesday:

• Worked with Michael to establish communication between the jacket and the pi
• Wrote moving average collision detection algorithm
• Implemented and tested the communication protocol between the pi and the jacket

Wednesday:

• Demoed the jacket and pi communication, showing off all the features
• Discussed possible improvements for collision detection and integrating the device onto the jacket

I worked on putting the demo together to show our project progress.

I constructed the jacket with all of the essential components we aimed for, the LED matrix, buzzers, and vibration motors. The Arduino nano on the jacket was the microcontroller for all actions, and it received instructions via Bluetooth.

After some basic testing, we did a full wireless test, and got the jacket to work as expected. We did not permanently glue or sew anything directly on the jacket yet, because we wanted to gather feedback from our demo first.

For future steps, I will have to finish constructing the jacket, and make sure all the connections stay in as expected. I might also have to consider printing out a small case for the circuitry, since having exposed wires is potentially dangerous.

For next week, we are planning to mount all the LIDAR and ultrasonic sensors onto the bike. I am starting to design some mounting templates for these devices.
