Arena Discussions

Post by peterwaller » Mon Jun 15, 2015 10:56 am

It didn't seem appropriate to put this in the rules debate section so I thought I would open a new topic for general arena debate not just my arena progress.
I went out and bought the wood on sunday morning and made some progress on the frame in the afternoon.
The 25cm square cut outs look bigger than I thought they would but as they are the biggest the pits can be that is probably not a bad thing.
Here is a shot of the frame screwed together and glued to the top.
Image
I have since glued the base sheet on which includes the pit area and used the four cutout squares from the top to double the floor thickness in the pits.
I just hope the polycarb will be delivered quickly so I can check it is all going to fit and work out how to join the cover.

Looking good peter! You're right that those pits do look bigger in real life than they did in the diagram, but we'll have to wait and see how they turn out. If you're still intending to have some small walls on the corners to prevent wall-sliding, that will contribute a lot to making the actual drop-off area smaller than it looks.

Keep us updated :).

They look like huge pits! I think a low wall round one side of each might be cool. Then you flipper people can have a go at lifting them over but there'll still be enough straight drop off too.

They are 25 cm but NY's FTS must be fairly close to that!!

I have been doing some calculations and the 250mm square pits give a total dropoff edge of 2 metres which is 45% of the perimeter which seems way to high.
Image
If I cut quarter circular pits and reduce the radius from 250 to 200 mm you still have 1.25 metres of dropoff which is 33% of the new perimeter.
Image
Numbers like these are hard to visualise so here is a pictures of each type of pit with a few robots for scale.
Image

Image
Personally I prefer the curved ones as it gives more fighting area but we could go with the square ones and walls at the edges or even low walls along part of the dropoffs the possibilities are numerous.
There have been a few post since I started writing this one by the way what is NY's FTS.

New York's Finest Taxi Service, which was Dave Lawrie's expanding ant at the last AWS (I suspect it'd still fit in those pits though!). I am slightly concerned for the scenarios in those pictures as it looks like the robots are being judged for some sort of serious crime...

Would there be any way to make the fighting surface interchangable?

Interesting developments. I'm definitely not telling you what you should do Peter, just giving more suggestions, but you could also consider only having two pits (could put diagonal walls in the other two to get around your dislike of corners), which might give you more options as to what you can do with the remaining two pits.

i'd be up for only two pits as i could still navigate my opponents into those well enough and spinners would be less likely to spin themselves out.

The idea of opening up this discussion is to get peoples ideas so don't worry about making suggestions.
It is never going to be possible to please everyone but the more comments people come up with the more likely we are to please the majority.
On the idea of two pits I hadn't thought of that but had wondered about two open pits and two with low walls for flippers.

I think two pits would be fine. I'd even be happy with 2 curved pits, and then as Scott says some sort of triangle in the other corners to stop people hiding in them. Maybe even some other hazard like a spike ?

Not much progress today I am a bit stuck now until I get the Polycarb.
Drilling into the edge of the 6mm thick end plates with a 4mm drill needs to be fairly precise so I have come up with a jig.
Image
The two side plates are mounted on either side of two pieces of 6mm Polycarb with a 6mm steel bar in the middle that has been drilled 4mm to exactly fit the drill required.
This ensures that the drill is always parallel to the faces of the material being drilled.
The holes in the 2mm wrap around sheets will probably be drilled in situe as the spacing on the outer sheet will be slighty greater than the inner sheet.
I will probably need another small jig to ensure those holes are all an exact distance from the edge of the sheets.
The 6mm end plates have been dispatched today, as have the threaded inserts / screws, and the 2mm polycarb is on 2 - 7 working day delivery from last friday so I am hoping it will all arrive this week.
Fortunately Soapbox is finished and the laminate flooring will not arrive until after the AWS so that shouldn't hamper my progress.
I thought that when I retired I could just relax and do nothing all day still it beats getting bored.

On the other arena hazards front, as i've said before, pegs in the floor near the drop off were a great addition to my practice arena. One on the corner of the pits or something would make a big difference.. Just another possibility.

The polycarb end plates, threaded inserts and screws all arrived but no sign of the main cover sheets yet.
I drilled and fitted the threaded inserts in one end plate to check the jig worked OK.
Image
Here is the end plate with an old sheet of 2mm polycarb fitted just to check it wrapped round OK.

Should improve visibilty as long as we don't get to many reflections from overhead lighting.
