This is a very interesting setup--I'd love to see some more details.
What kind of drivetrain do you have under there?
And, the all-important question...how high can you go?

Some other questions...
How close to the goal do you have to get to cap?
Have you experienced any difficulties with the tetras falling off?
I can't see it very well... do the tetra arms extend outward in any way?
Do the arms rotate inwards so that the bot fits within the size limit? Or does it fit within the box when the arms are facing outwards?
What type of a setup do you have for your drivetrain?
How do the arms extend?
Can you cap two goals at once?
Looking great!

What kind of drivetrain do you have under there?
We use the two gearboxes supplied with the kit, one on each of our drive wheels. There are 6 wheels, 3 on each side, with the two middle ones connected to the motors. The other four wheels are to keep it going straight. We originally used casters, but since the motors aren’t exactly the same speed it would start to veer off to the side.
And, the all-important question...how high can you go?
The bar that the tetras hang from can go up about 13.5 feet, or however high you need to go to put the sixth tetra on the middle goal.
How close to the goal do you have to get to cap?
Pretty close, depending on how far back the tetra is on the arm. This was a big problem until we fixed it by making the top segment of the telescope longer, then tying a string from the top to the arm that hangs down so it can’t slide back too far.
Have you experienced any difficulties with the tetras falling off?
Yes, we originally didn’t have much to create friction and “grab on” to the tetra. We were the first at the Great Lakes Regional to break a tetra, (Although that’s not something to brag about.) because we pivoted around our center really fast and the thing slid off and flew. We since wrapped some more foam stuff around the tip of the bar and it works pretty well.
I can't see it very well... do the tetra arms extend outward in any way?
Negative, although we have elongated them since this picture was taken.
Do the arms rotate inwards so that the bot fits within the size limit? Or does it fit within the box when the arms are facing outwards?
Our robot is somewhere around 100” long when they are down, they fold upwards into the rest of the arm.
Can you cap two goals at once?
Well, we can do one right after the other if we have a tetra on both of the arms.
