      I'm apart of a robot competition involving collection of soda cans and depositing them at a set location.

      Soda cans are scattered on their side throughout the competition floor, we have to pick them up with our robot and place them in a bin to collect points.

      One design we are thinking of is to collect cans through the mouth of the robot, and use rolling devices (green in the picture above) to "scoop" up the cans and take them to a higher level so they are ready to be deposited into the final box.

      We are stuck in this design though because we don't know how to get the cans oriented along their long axis (the axis where they can roll)

      Any ideas how we can get the cans oriented along this axis?

      Consider adding vibration. Imagine a broad plate that u lay can in different orientations, by shaking it in the right direction and magnitude they finally will be oriented in the same direction.

      I'm not sure how you plan on doing your initial scoop, but if you impact the can in any way at most orientations, if you can prevent it rolling away, it will tend to orient itself the way you want it to. The exception being if it happens to be near 90 degrees from where you want it to be.
