Boy that just goes to show you can't predict how GDC will rule on anything. :yikes:

Re: Smaller Robot Perimeter
 

If you want to maximize volume, why don't you go with a 35" diameter circular robot? A 35" diameter robot would have a circumference/perimeter of 110".

Re: Smaller Robot Perimeter
 

It is often prudent to leave yourself a little wiggle room when it comes to sizing. You may want to downsize to 27 3/8". ;)

Re: Smaller Robot Perimeter
 

I predicted it correctly....it's been typical over the past several years that an overall robot "volume" measurement includes the bumpers.

But then, my team is not trying to push the volume boundary, so we can afford to be pessimistic.

Re: Smaller Robot Perimeter
 

We put together our frame last night, and measured it at 110.5".

I'm liking this rule change more and more... you don't have to intentionally design undersized so your bolt heads fit in the sizing box - just make it to the dimensions you want and ignore the bolt heads (per R02)!

Re: Smaller Robot Perimeter
 

....and if you accidentally add some plates or something to the sides and it gets too big, just chamfer the corners!

(spell check didn't like the word "chamfer"????)

Re: Smaller Robot Perimeter
 

Well this throws a wrench into things...

Re: Smaller Robot Perimeter
 

Our perimeter (without bumpers) is 110". Does this QA thing mean that we are violating the perimeter rule when we put our bumpers on?

We have not made them for our robot yet but I assume that we will be...


Or am I understanding this wrong?

Re: Smaller Robot Perimeter
 

The bumper inclusion is in regards to the 54" diameter cylinder. The 112" frame perimeter is the outer polygon of your robot without bumpers. HTH

Thanks.

Re: Smaller Robot Perimeter
 

Our club officers and mentors (myself included) have decided to embrace this growing trend of making things smaller, and decided to make a really lightweight robot.

Of course, that was after the hexagonal robot milled out of a solid aluminum block with decagon wheels and a quadcopter swarm for a manipulator was ruled out.

Re: Smaller Robot Perimeter
 

3735 has been having to think more innovation on how to fit inside the perimeter, but so far we don't have any major problems

Speaking of the 54 inch diameter, how is first going to measure if the robot goes outside of it during the competition?

Re: Smaller Robot Perimeter
 

During robot inspection they will but your robot into a circle and then you have to move the robot into its furthest extended position. This will be almost identical to what they did in 2011.

Re: Smaller Robot Perimeter
 

The problem with that is the inspector won't know what orientation the robot will be in while climbing the tower. The 54" cylinder is with repect to the floor and if the robot tilts while climbing it could go out of the cylinder.

Re: Smaller Robot Perimeter
 

That is true. Looking at the rules I see a place where they will need another update.

ROBOT height (as defined in relation to the ROBOT) must be restricted as follows during the MATCH:

If in contact with the carpet in its AUTO ZONE and/or its PYRAMID, ≤ 84 in.

A ROBOT’S horizontal dimensions may never exceed a 54 in. diameter vertical cylinder.

Those 2 rules directly contradict each other because the 84" rule is in relation to the robot, but the 54" rule is in relation to the field.
