Set Sail/Disable Ship (Buoy) Discussion

Is the 3rd object in the Set Sail/Disable Ship(Buoy) a white corrugated cutout on which a yellow fan is drawn, or is it a yellow, fan-shaped cutout?

Disable Ship

We were also unsure of whether it is a cutout or a white rectangle with a drawing. In either case, we feel it is important for the object to be three dimensional (like last years) and not a single flat piece of corrugated cuotut as this would be hard to manipulate and hard to detect if it rotates the wrong way.

Cutout

I agree that it would be hard to maniputae the object if it rotates.  And from my side, trying to make 3D versions of objects would get difficult...

 

How about a cut out in the image (for example, the circular hub of the propeller), that you can use to manipulate the target?

propeller

Currently, it could be either.  Suggestions?

Cutout (Propeller)

We are not very sure about what do you mean by a "cutout to manipulate the target", are you referring to a hole then? (near the central hub in the propellor)
In any case, even we feel it would be better to have a 3D object, or if it is possible to keep the 2D object always facing front (avoiding any unwanted rotations making the detection difficult), that too will be okay.

Cutout

Yeah, I mean a hole in the center where the hub of the proeller would be. 

I would also use a line on each side of the 2D object to keep it facing "front".

 

However, there's internal talk of changing this a bit (It would be a 3D object).  I'm trying to get this finalized as quickly as possible.

Any updates on what this 3D

Any updates on what this 3D object would be like? We would like to be able to test on this as well soonest.

3D object

It looks like the 3D object will be a "buoy" with a pressure plate.  Push the plate to release a balloon (or something like that) which will rise from the water's surface to visually indicate a successfull touch.  I'm not making it, someone else is, so I'll will pester them until they post what they are building.

Here we go again

RGB buoy Mk.2?

RGB LOL

"Thankfully" no. 

I've pestered them, and this is what it will be:

The object will be a buoy-like sphere ~9" (~23cm) in diameter (could be bigger), yellow in color.  There is no external pressure plate, instead there will be an internal mechanism to sense tilt (so that you may bump it from any direction).  Once it reaches the desired tilt angle, the release mechanism will trigger.  Currently, the tilt angle will be set for 10° (but it's adjustable).  For all external purposes, it will "look" like another buoy (aside being made from different materials)

If this doesn't work, the fall back will be the Polyform A0 Saturn Yellow buoy we've used before (Amazon also sells them)

Thanks!

That sounds much more reliable thanks for the information Dave!

Do you happen to know the color of the buoy if it is the custom one?

Buoy color

The "buoy" will also be yellow.  That way, if we have to switch, there should be minimal impact to you.
