  • [URGENT] Point task breakdown

    We saw the points breakdown and have a few issues we hope to provide feedback for and can be addressed before the start of competition this Saturday.

    Underwater Ring Recovery
    - The points for the ring recovery is very little given how challenging it is to even recovery a single ring. Recovering a single ring in the upper level is only 1 point...(correct us if we are wrong in interpreting this) LARS points are fine but what is LARS if all we end up doing is to drop the AUV into the water and recover it again because we decide not to do it due to too little point allocation, then that task would not be meaningful. From robosub experience, Im sure we all know how difficult it is to even pick one ring typically and the right amount of points should be accorded. Also can we check on the rational for the point difference for the heights? To us, there is no difference in the rings being at different heights. We would suggest each ring to increase to 15 points and reduce the LARS to a total of 20.

    Obstacle Avoidance
    - We think too much points are allocated to a task that is not even comparable in difficulty to everything else especially for the lawnmower pattern which is essentially just doing the same thing 10 times and you get 100 points. Suggest to reduce to 50 points.

    Detect and Deliver
    - The Detect and deliver task is one of the most challenging task in general. We would suggest to give higher scores even for the large hole(comparing against the other easier tasks like docking) so that the scores are more balanced. Suggest to to increase per ball through a large hole to 7 points.

    Bumblebee,

    Underwater Ring Recovery
    - We were under the impression that for this task we were only supposed to recover a single ring, so I understand your rationale for the ring scoring (assuming you took out the point multiplier). You are dropping the overall score of this task from 138 to 110 with your suggestion. Given how technically challenging it is to design and build a sub/deployment system, I don't actually think the points need changed for deploy/recover. Mainly because if you lower the points too much, it would be more worthwhile to just have a fishing pole mounted on the ASV.

    Obstacle Avoidance
    - The lawnmower pattern is relatively boring compared to the other tasks, but I think its there for a good reason. Not a single team in 2016 finals ran the obstacle field, and it may have only been attempted a few times during practice/qualifying. Now the incentive is much stronger to attempt this task.

    Detect and Deliver
    - We could go either way on this one. We see the underwater task as the most difficult, but the increase to 7 points instead of 5 may have some merit. This is one of those where the points possible may be adjusted based on team performance during practice/qualifying.

      We too were under the impression that only a single ring needed to be recovered.
      Agree with Tompd27, the incentive to try obstacle avoidance is there. We also thought the Detect and Deliver was a relatively easier task than underwater.

        For the Underwater task, we fully agree that it is the toughest out of all the challenges. We were typing this at the airport whilst trying to catch our flight :P, so didn't do the calculations properly. How about 20 points per ring and keeping the LARS to 30. That totals the points to 150. keeping it still the highest scoring. The point is to provide greater incentive to do the task given the higher level of risks involved in deploying the AUV even if only recovering 1-2 rings which I believe most teams are aiming to do.

        Also, different water columns honestly don't make a difference: In fact it is harder to do it from the top due to the swells from the waves. Even building a mechanical actuator from the ASV is challenging given payload limits/swells that can affect the manipulation. Anyways so long as the points for the three levels are reasonable, we are okay with having different points for this.

        For the collision avoidance task...honestly in 2016 semis and finals only two tasks were attempted - docking and scan the code, being the easiest and really because most of us weren't well prepared. Don't agree why collision avoidance should be so special and to score even more than detect and deliver which is way harder.
