ID | Risk | Type | Description | Likelihood | Consequence | Risk Reduction Plan |
1 | Electric System Failure | Technical | The battery or electric system fails due to incorrect operation. | 1
(-1) |
4 | • Add reverse voltage and overvoltage protection.
• Document and regulate operation. |
2 | Work Delay | Schedule | Heavy workload puts the team behind the schedule | 1 | 5 | • Optimize the WBS to break down the workload into manageable pieces. |
3 | Run Out of Budget | Financial | Run out of funds purchasing parts and repairing robots. | 0 | 5 | • Make purchasing decisions carefully after the trade study. |
4 | Latency for Real-time Operation | Technical | Communication latency between master computer and UGV fails real-time operation. | 4
(+1) |
4 | • Use a higher speed router as a wifi booster. |
5 | Poor Weather for Validation Tests | Schedule | Poor weather prevents/delays the system from outdoor experiments. | 1 | 3 | • Monitor upcoming weather.
• Schedule tests beforehand. |
ID | Risk | Type | Description | Likelihood | Consequence | Risk Reduction Plan |
6 | Even Temperature Distribution | Technical | The temperate difference in the test field is close to or smaller than sensor noise. | 1 | 4 | • Use sensors with higher sensitivities based on previous experimental results.
• Add heat sources to the test field to increase temperature variance. |
7 | Poor Localization Accuracy | Technical | Localization accuracy is not high enough considering the size of the test field. | 1 | 5 | • Use RTK GPS instead of a built-in GPS. |
8 | Slow Temperature Convergence | Technical | Temperature converges too slow for ground truth and onboard sensors to meet the time requirement. | 1
(-3) |
5 | • Use temperature sensors with the faster response time. |
