pretty complex.

That is awesome. I'm a huge fan.

Question: How many tetras can you stack at once?

Having wasted 24+ hours on the camera...

NICE CAMERA MOUNT

(we took it off the day before we shipped, but weren't wise enough to put it back on when we did ship, so we're going to put it back on as soon as we get to regionals)

Very interesting..what's the center tower for? stability? How far up can you reach?

how did it break? just bend? or snapped? and in what direction? What were the dimensions of the aluminum you were using before?

Re: pic: Team 1392 Kinematrix's Robot

steel if you have the weight, titanium if you have the supply...same for carbon fiber...but isn't daydreaming nice?

Anyway...more realistically...bosch (spelling is probably wrong) Al would be close to the weight and the internal structure on it might help it hold up a little better...

How much weight do you have to work with?

But really honestly if it got "stuck" someplace you would probably be better off fixing it so it doesn't get stuck than getting a new material. A flaw like that could show up no matter what material you use...plus issues like weight and center of gravity...or even if it does hold and you still get jammed mid-match you could become useless.

hmm i would suggest extruded aluminum, once again if you have the weight. very nice stuff i might add, we used it on our last yr's robot.

i would advise against using extruded aluminum. a while back, a white paper was put up that compared the strengths of various profiles (square tubing aluminum and aluminum extrusion being two) and square tubing came out being much weaker. as others have said, the best option might be to go with a stronger material, such as steel, or maybe thicker wall diameter, if possible.

just to get a better feel of things...how much does the current structure weigh in Al?

the whole scissor structure weighs about 16 pounds

When I first saw the team number, I was like, "Who posted the picture?" But then I realized that it was 1392, not 1293.

It looks solid, and if it can outdo these jointed arms everyone's using, you'll be up for a great run.

(The limited experience I have seems to indicate that it's always the designs out of left field that amaze everyone.)

Re: pic: Team 1392 Kinematrix's Robot

Ya its definately different from those arms..hopefully we'll do well..if we don't..thats ok too..it'll be fun just to get out there with our bot and play a few matches

Re: pic: Team 1392 Kinematrix's Robot

did it snap while holding a tetra or just going up and down?
