Team Vision for Subsystem Level Build & Test Phase

For this phase the team vision is to finally get a bunch of work done. After coming back for the summer we realized that our radar had completely stopped working. After a week of trying to fix it ourselves, we reached out to the manufacture and worked with them to get a replacement board. This has all eaten up a very large amount of our time. As such, now that we have our working vital piece of equipment we plan to set out as a team on a journey to get as much work done as possible over the next three weeks. Some of our goals include testing the new radar, finishing the software for wireless communication, and negate some risks that have popped up do to the time restraints. Additionally we shall continue the plans from last phase that got put on hold such as continuing component integration, fleshing our our test plan procedure, and managing our risks and BOM will be accordingly.

Functional Demo Materials

We were able to connect the Raspberry Pi Zero W to the radio transmitter and transmit a signal to the FM receiver. The signal transmission is demonstrated by the LED at the transmitter being turned on, and the signal being received is demonstrated by the LED at the receiver being turned on. The micro controller was mainly just used as a power source, the script for the radio transmission was all run on the Raspberry Pi.

Above is the receiver with its LED that lights up when a signal is received. This is powered by the micro controller.

Entire system overview, you can see the LED on the transmitter is lit, signaling that the system is currently transmitting information.

Design Review Materials

Our Subsystem Build & Test Prep Review presentation was given on October 8, 2019.

Plans for next phase

Now that we once again have a working radar unit, the radar and pi software can be finalized. With the software done we can have half the team work on completing our test plan while the other half finalizes the design for the waterproof casing. During the test plan portion we are aiming to achieve another big milestone: Pi and Radar test with vehicles in a real life simulation on the road.
