Successful Risk Identifications
One of the remaining risk that has been identified was the hardware, electrical and laptops fail- ures during SVE, which has actually happened during both SVE and the SVE encore. During the SVE and SVE encore, a hardware failure was that wheels fell off from a rover due to broken axles. Additionally, a linear actuator failed to function properly before the SVE encore, which severely obstructed the progress of the rehearsal. However, the risk was not marked as either a high likelihood risk or associated with high severity.
Failed Risk Identifications
Although the hardware failure risk has been identified, but it has been marked as a low likeli- hood risk associated with low severity, which did not turn out to be the situation. The hardware failure did happened and severely affected the demonstration of the SVE and obstructed the rehearsal of the SVE encore. Moreover, due to the hardware failure, the replacement of the hardware parts actually affected the performance of the entrapment detector, whose hyper- parameters heavily depends on the hardware configurations. So during the SVE and the SVE encore, the entrapment detector did not perform in its best tunned status, which was a risk that has not been properly identified.
In addition, the risk of faulty wiring has not been properly identified, but actually hap- pened, which leads to unexpected stopping of the motors. A pinion was also destroyed since a Roboclaw cable was plugged in backwards. And this issue has added to the delay of the project.
Another management risk that was ignored was the unreliable Internet/Git access from the AutoKrawlers. It has been a long existing issue, but the way we went around it was to trying copy and paste everytime any file was updated. As the software system became more complicated, appropriate version control was necessary. But the unreliable Internet access was a great obstruction that wasted a lot of our time.

Memo for FVE
- Recharge the batteries
- Check the integrity of the rovers
- Store two rovers separately in two different locations
