This is awesome! Can't wait to see you do it without spotters and faster. Will you be "dumping" any discs in the pyramid goal?

Cool. It is tricky aligning to the corner for a straight climb. How have you solved that challenge?

That is the plan.

Camera mounted over the jaws.

What the size of the frame perimeter? It looks like its way bigger than 112", but maybe I'm just seeing things.

Very stoked to see this in person.

Looks like a pretty awesome way to climb. Guess that's another one of the climbs checked off. So far, we have the first 30 pt climb, the first corner climb, and now the first second end over end climb.

In spec. 111"

Can you post it to youtube or some other way so that those of us who have facebook blocked from school can see it? Thanks. I can't wait to see it. We are working on our climber from the corners as well. My students will be excited to see someone who accomplished it. Great job.

Good job guys. I have not seen anyone climb end over end. So is this all your bot can do? and IF you can you mught want to add a final locking arm incase you lose power when at the top.

Looks great guys can't wait to see it in competition at Hartford this year!

The perimeter is exactly 111.5" around. It was measured by multiple people. The locking arm idea would be great if the system wasn't using pneumatic cylinders to lock on the pole. The system will hold as long as there is pressure in the system, and we've checked our system multiple times already.

But you're using motors to rotate the arms right? I think his point was that if you're in the middle of a flip when time runs out, you could have a pneumatically actuated brake that prevents your arm from backdriving. Otherwise, if your robot is in mid-flip and is, for example, horizontal, it's almost guaranteed that if power is cut the arm will backdrive and your robot will sag below the line, reducing your score.

It's possible your gear reduction is high enough that simply putting the speed controller in 'brake' mode is enough to do this, but you'd have to check.
