Preloading uber-tubes

[jee7s]

The switch will almost certainly be illegal.

I'd say you have two options:

1. If your claw is at all flexible, you could just push the ubertube on to it. Since both the tube and your claw could deform, that would accomplish the goal. This is substandard, though. If this is the situation you're in, you'd also have problems removing a tube at the end of a match.

2. The more preferable solution would be a way to manually open the claw, like a pin or a spring. That way, you could open the claw without a motor for the start of the match, and be able to remove tubes at the end of a match.

If you can provide a bit more detail about your mechanism, I think the folks here will be able to better help you.
