Schedule update:
We have purchased and received most of our core components that we need to test, including the ultrasonic sensors, raspberry pi, and some various components. We are still waiting for our OAK-D depth cameras, but in general we are in time for testing our components.
No changes have been made to the schedule so far, next week, we will start testing our sensors and incorporating our raspberry pi into the system.
As for risks, the main part is whether the sensor models will be good enough for our purpose. This is something that we will be testing out next week, if they turn out to be insufficient, we have several backup sensors that we have been looking at, and we will purchase them immediately. If they do work, we will likely purchase more of the same sensors.
