Image Discuss: Team 60 - Testing the Robot

[sanddrag]

I blew up the pic in Photoshop and I've come to some conclusions and I've come across some more questions.

CONCLUSIONS:

In the center of the side of the robot closest to us in the pic, there is a large worm gear driven by a worm on a globe motor just behind the worm gear. The worm gear is affixed to the shaft which rotates the red bars downward. The same is true for the opposite side since another globe motor in the same orientation is clearly visible behind the battery.

The red bars rotate down to lift the robot off the ground making it immovable.

The biggest pneumatic cylinder is not attatched to the white A-frame structure.

A pneumatic cylinder is attatched to the white A-frame on one end and on the other end attatched to a fifth wheel similar to the 4 drive wheels but set up to be like a caster.

If the white A-frame rotates downward, it could be used to knock over a stack and keep all the bins in line to push into scoring.

QUESTIONS:

I cannot tell if the giant white A-frame structure is rigid or if it rotates downward or something. I cannot see the far side mounting points (if any)

I have no idea what the two identical pneumatic cylinders are used for.

I have no idea what that large pneumatic cylinder is used for.

What is the yellow thing on the right side behind the Chiaphua?

It looks like there are 4 cylinders but none of them is the Parker one in the kit.

And what are the four mounting brackets on each corner for?
