How many small tetras(not goals) do you think EACH robot will be able to cap?
Edit:- Total number of small tetras stacked, during the duration of a match(could be stacked on various goals)
Is this on one goal or for the duration of the match?
just a note on this…woody told me at kickoff that they put as many as 12 on a goal and it got very unstable so that was going to be their “safety limit” whatever that means
also for all those people thinking they are going to get 7+ on a goal they had better do that all at once or when placing the last tetra they will have to lift it 3.5 feet over the initial goal height
If there is any team that is able to stack atleast 3 high, then their competitors are incompetent - The mechanism just to stack that many high would have to be so quick, and your alliance members would have to be playing perimeter defence the entire time – only way without intereference is on and off the human loading bay… but then you have to cap
I think this strategy will be frustrating… bc the engineering to do so will be timeconsuming and the reward almost nothing
i think if a robot can do 3 that is goign to be very good and any more then that will be amazing
the more I think about it, and after i lifted one of the tetras i think that 3-4 will be a good stack and anymore will be from a really good team.
I can’t possibly see anymore than 3 or 4 ontop of a single goal…unless someone is trying to dump more then 3 or 4 at a time (and even if they are) I think we’re going to see some self or assisted tipping of robots…
During the two minutes of the match, an efficient robot will be able to place more than 7 on goals I think, if they have everything going for them. This also assumes that most of the tetras will be placed on goals near the loading zones, not on the other side of the field (I think a team could get maybe 3 on the other side of the field, with robots playing defense).
The maximum height of a stack on a goal, I think no more than three or four because the stacks start to get very high, and most teams will be incapable of making an arm that can go high enough without tipping their robots over. These tetras are 9 lbs after all.
you know what i just noticed right now, tetras can be used as a counter weight. so stack a couple on top of your robot low down, or even just drag them around but have a firm grip over them. then you have more weight at the bottom so less chance of flipping. and also since your total weight goes up, other robots will have a harder chance moving you.
I think a very good capper will be able to cap as many as 7 tetras on one goal. The robot would have be pretty quick and the grabbing mechanism would have to be very consistent, but its possible.
WOW! i thought that 4 was a good number but i see the CD community thinks otherwise and we better make a darn good robot! :o
Considering tetras stacked in different goals, I think 7, maybe 9, is a good number.
Assuming a robot can cap goals with a stack of 4 tetras at a time, I think the possibilities for 7+ are pretty good.
4 a stack per goal is a good number, though… at least… I think. If anyone can do more than that, I’ll bow down and worship 
The idea that a team could add additional tetras onto their robot as ballast to counter the tipping problem makes a lot of sense.
I have to agree with you on this. Our (Team #1288) measured the space between each small stacked tetra and it came to be about 4.5 inches between them. So all you people who think that you can get more than 7 stacked need to remember that there is a certain height that your robot can’t exceed in the arena( not the height requirements but an arena restriction.) So I don’t see you getting more than 3 or 4 at the most. THANK YOU AND HAVE A NICE DAY!!!
what is the field maximum hight anyways??
i’d say you could stack as high as you can… meaning as high as your robot can reach
I’m thinking that it’s going to be difficult for teams to be able to cap 4 at a time. They’d need a pretty strong arm to be able to lift a 36 lbs in tetras (which is about 28% of your robot’s weight) AND since that’s being lifted away from the robot, that’s going to be a lot of torque on the manipulator. Then you need to worry about weight distribution even if it can carry the torque load. Certainly this is possible, but difficult. I will be impressed to see 4 stacked at a time.
someone who can stack 4 at a time consistently, or even semi-consistently will win many awards and/or regional titles.
I agree that stacking 4 or more tetras at a time will put a huge amount of stress on the arm, and will make the robot very unstable. I believe that most robots will attempt to manipulate one at a time.
I can see a strategy between teams where one robot would go get tetras, where another one would stack them. this way I can see many tetras all over the field.
