Survey Date | Op | VCS Ident | TREX Ident | Ticks | Duration | Success | Remarks per run | Overall Remarks |
--- | --- | --- | --- | --- | --- | --- | --- | --- | ---
4 Nov 2009 | F. Py | 2009.308.04 | 2009.308.07 | 25197s | 6h 59m 57s | TRUE |  |  |
5 Nov 2009 | T. Maughan | 2009.309.00 | 2009.309.01 | 2043s | 0 34m 3s | FALSE | Model ascend longer than expected | over constrained model of the ascend in TREX. - a patch was applied on other branches but not in the volume survey deployed for this run. |
5 Nov 2009 | T. Maughan | 2009.309.01 | 2009.309.06 | 2064s | 0h 34m 24s | FALSE | Model ascend longer than expected |  |
5 Nov 2009 | T. Maughan | 2009.309.02 | 2009.309.07 | 1016s | 0h 16m 56s | FALSE | Interface vcsServer socket closed | VcsServer: in analyzing the failure it was determined by Frederic and Hans that the implementation was overly complicated and could be simplified to improve maintainability and reliability. |
5 Nov 2009 | T. Maughan | 2009.309.03 | 2009.309.07 | 1012s | 0h 16m 52s | FALSE | Interface vcsServer socket closed |  |
9 Nov 2009 | F. Py | 2009.313.02 | 2009.313.04 | 19026s | 5h 17m 6s | FALSE | AUV MVC altitude stop: it was believed that sea conditions caused the dvl to malfunction as the ping temporal spacing caused it to hear echos and deliver a wrong altitude. No way for TREX to recover from navigation instrument failure. | Altitude: Hans changed the frequency of the signal beams to avoid the false altitude. He also patched another issue in the driver. |
10 Nov 2009 | T. Maughan | X | 2009.314.01 | 0s | 0 | FALSE | Failed to execute Navigation (crash) | Navigation crash: All components of mvc needed to be compiled with a specific flag. After two tries, we drove the boat back and applied the rebuilt code. |
10 Nov 2009 | T. Maughan | X | 2009.314.03 | 0s | 0 | FALSE | Failed to execute Navigation (crash) |  |
10 Nov 2009 | T. Maughan | X | 2009.314.05 | 7029s | 1h 57m 9s | FALSE | mvc-dmo1 crash | MVC-DMO1 crash: it was determined that a patch should be applied to QNX, Hans patched the QNX on the vehicle and the test machines. |
18 Nov 2009 | T. Maughan | 2009.322.07 | 2009.322.09 | 577s | 0h 9m 37s | FALSE | parosci + ahrs issues | Post deployment analysis showed significant differences between the DMO mvc qnx code and the autonomy branch of the mvc qnx code. |
18 Nov 2009 | T. Maughan | 2009.322.09 | 2009.322.10 | 10398s | 2h 53m 18s | TRUE | AUV issue: Tailcone locked resulting in the abort from TREX. Also, bad weather motivated the attempt at early termination. | Tailcone issue was found to be loose screws on one of the actuators. Also, the error recovery was analyzed on the TREX side and the tailcone failure revealed a dispatchability issue at TREX level which is now corrected by avoiding to dispatch a behavior before it can start (to be refined but OK) |
19 Nov 2009 | F. Py | 2009.323.01 | 2009.323.02 | 4274s | 1h 11m 14s | FALSE | parosci error | This error was related to the code diffs in the autonomy branch of mvc code |
19 Nov 2009 | F. Py | 2009.323.02 | 2009.323.06 | 2094s | 0h 34m 54s | FALSE | parosci error | " |
8 Dec 2009 | F. Py | 2009.342.04 | 2009.342.05 | 9359s | 2h 35m 59s | TRUE | altitude stop: (see Nov. 9). Gulpers: it appears that the gulper commands were potentially too closely spaced for the driver. | This error was related to the fact that our branch was not up to date and specifically did not include latest updates related to AUV HW modifications |
