  • Weighted base
    Posted by James Hughes at 2018-02-20 16:24:41
    Can we assume there will be rebar or some other weight applied to the base of the origin and scoring towers? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- yes ~6' each in the base structure
  • Scoring
    Posted by Ty Adair at 2018-02-20 16:23:45
    If a cube (or any other scoring object) is not physically touching the upper scoring shelf but instead stacked on top of another cube (or any other scoring object) that is resting on the upper shelf, does the stacked object still score on the upper shelf (2 points) ? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- yes
  • Point of View to challenge
    Posted by Dennis Rockhill at 2018-02-06 13:24:45
    What angle are we looking at the challenge? Do we move objects from origin on left to scoring on right? Or do we move them from origin (close to scoring (far)? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- origin near wall, to score farther.
  • PVC Pipe Size
    Posted by Cindi Pietroski at 2018-01-30 13:11:04
    The description on the BOM references all 1/2" PVC pipe, but a few of the Part No.'s translate to other sizes (e.g. #26504 = 1" PVC Pipe). Are all of the pipes 1/2" diameter? ————— it is 1/2”, I will update the BOM to reflect
  • Rod Design
    Posted by Damiane Gardner at 2018-01-29 16:56:28
    Where can we locate the BOM and build instructions for the rod? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE added two new picts and relabeled the BOM
  • Rods
    Posted by Patricia Meinhold at 2018-01-23 16:20:32
    I am trying to sort out constructing the rods. If one should fall from the platform, is it expected that it would sink to the bottom, or be bouyant enough to neither sink to the bottom nor float to the surface? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE they should sink, if need be a bolt can be added to the nut.
  • Distance Confirmation
    Posted by James Hughes at 2018-01-22 09:54:52
    I read above that the distance between towers is 10'. How far from the pool wall is the origin tower? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE-5'
  • Material Cost
    Posted by James Hughes at 2018-01-22 09:51:41
    I see the cost for printing 3d parts is 2.3 cents per gram. That's good news. Our kids are also testing carbon fiber parts. How would carbon fiber parts be priced towards our budget? Is there a cost per gram? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE-procurement costs for the material
  • More info about the Rods?
    Posted by Dennis Rockhill at 2018-01-22 09:50:07
    Are there instructions about the rods? I see the materials on the BOM, but not sure how they go together - specifically the flanged nut. ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- nut gets pressed into the bottom of the rod. ------------------------------------------------------------------------------------------------- Thanks - Is the rope attached just by tying knots to the inside of the pipe? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE-a zip tie holds it together in the middle
  • Origin/Scoring Structures
    Posted by Ty Adair at 2018-01-17 14:19:03
    Will the fittings and pipes for the origin and scoring structures be glued or screwed together? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- only those joints that are required to keep the course upright will be screwed.
  • Rings
    Posted by Chris Maercklein at 2018-01-17 14:17:41
    Air can be trapped in the rings, making them extra buoyant. Tie them to a weight and sink them to the bottom of the deep end for 20 minutes prior to use. The increased pressure helps force the air out. ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- we pre-soak all our courses for at least an hour as well
  • 2018 Challenge Course
    Posted by Chris Maercklein at 2018-01-17 14:16:43
    Will this course be weighted with rebar? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- yes 6' of it
  • dry weight
    Posted by Richard Pettys at 2018-01-04 17:54:16
    Is there a dry weight for rings and cubes? Our rings were built per the specs listed, but seem too buoyant. (i.e. they nearly float, so the slightest current sweeps them away and they end on the other side of the pool. Can you give a dry weight for all challenge items so we can verify we have built them correctly? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- will work on that, but wont be helpful as you would think....
  • Water current
    Posted by Richard Pettys at 2018-01-04 17:53:10
    In our practices, pool currents seem to regularly knock rings and cubes off the scoring platform - without any contact from the ROV or the ROV even being in the same area as the scoring platform. Is this an issue at competitions, or is the water typically calm enough that this doesn't happen? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- make sure you have drilled all the vent holes, but we turn off all the pumps in the pool.
  • Third Shape
    Posted by Thor Himley at 2017-12-29 12:17:27
    Is there a shape in addition to the rings and cubes not shown? I note the scoring rubric identifies nine shapes possible to score, and there are three cube and three ring slots on the origin platform. I also note three 'holes' in the origin platform, but no shape in them. Is there going to be a pipe or other object in those origin locations that will be required to be transported to the scoring platform? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- the third shape will come out of our archives, it is being updated and tested. Published plans will be up first week in JAN
  • 2018 Challenge
    Posted by Andre Samuel at 2017-12-14 09:51:43
    What is the material used for the platforms and how is the platform being secured to the PVC pipe stands? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE-- 18" x 24" White Coroplast Sheet USPlastic P/N 44267; zipties
  • platform locations
    Posted by Bronwyn Korchnak at 2017-12-14 09:49:24
    What depth of water will these be in? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- ~6' How far apart are the platforms? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- 10'
  • when do we call time
    Posted by margaret spigner at 2017-05-16 09:02:34
    do we call time when we hit the wall or do we have too surface at the end of the challenge? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- surfacing is required.
  • Cubes
    Posted by Maureen Barrett at 2017-05-09 07:52:04
    At regionals, the cubes easily drifted away when picked up and were almost neutrally buoyant. All the pipes of the cubes had foam in them. The build directions on the SeaPerch website still state the backer foam (5/8 in. polyurethane caulk saver) should only be in the top four pieces. Is that still the case? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- Build directions stand.
  • adjusting probe during challenge
    Posted by Harvey Bonser at 2017-03-21 09:12:08
    I believe that this has been asked and answered but just to clarify. Can the probe for picking up the cubes be adjusted during the competition and if so within what parameters? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- pivoted is ok. removed is not
  • Weighing challenge down
    Posted by Gregory Kane at 2017-03-21 09:11:23
    Is the challenge weighed down to keep from moving when hit by ROV? Is yes will it be with rebar ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- yes rebar is used
  • Cubes..water log?
    Posted by Bronwyn Korchnak at 2017-03-21 09:10:52
    My students are questioning if the backer foam can get water logged and effect the weight of the cubes. I don't think so but thought I would check for other thoughts on this. ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- this has not been a issue.
  • Rings
    Posted by D'Angelo Cain at 2017-02-27 08:25:55
    I understand that the rings are made of rope and connected with copper rings. Is the rope buoyant? More importantly, will the rings always be upright on the bottom of the pool, even if moved and dropped? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- they are designed to stand up.
  • Backer Foam?
    Posted by Will Walker at 2017-02-27 08:25:13
    Is that the actual name of the material? And where can it be purchased from? Is it pretty much the same as inserting pieces of pool noodle? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- Frost King 5/8 in. x 20 ft. Polyurethane Caulk Saver
  • Scoring
    Posted by Van Lam at 2017-02-27 08:22:34
    When does the ring or cube get scored? At the end of 15 minutes or when the ROV reaches the wall? What if the cube are hung but drops when another cube is getting put on the other arm or the fact that a ring may have moved into a different position as a result of the stand being hit by the ROV. ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE- Scoring is done upon completion of the run.
  • Time to accomplish the challenge?
    Posted by Gregory Kane at 2017-01-31 17:48:19
    What will be the maximum amount of time teams will have to accomplish the challenge? ----------------------------------------------------------------------------------------------------------------------------------- RESPONSE-- 15 minutes
