Since the last report, there are some small risks that have appeared. One is a change in plan for the control tower. With on-campus 3D printing costs being much higher than originally expected (~50x more expensive), it seems to make much more sense to buy a container for the main control tower body and 3D printing parts to supplement it. While this has changed our control tower design, because it is not an immediate concern in our schedule, the risk is significantly mitigated. In some ways, it could also simplify our project, as we do not need to worry about designing the whole control tower body, instead just modifying an existing structure to fit our needs. Additionally, there is some risk associated with our decision to switch to two Arduinos instead of the originally planned one. This decision was made because of the need for more I/O than one Arduino could provide. Although the Jetson Nano should be able to handle connecting to two Arduinos simultaneously, it does still increase the complexity of our design to an extent. However, it should not strain our hardware and we are confident that the additional complexity in dealing with an additional Arduino is not so much to be a notable concern.
We still seem to be mostly on schedule, and any current delays do not hold back the schedule, as they can be performed in parallel with other current and upcoming tasks.
Here is a picture of our initial 3D printed strainer arm mechanism:
