Is that little piece of surgical tubing the launcher for 2486? If it is, wow they got a good shot out of it. lol

No that is a clever way of keeping the ball in place that 4183 also used, I don't know if they adopted it from us or if it was separately thought of but it works either way.

When a ball rolls into the robot through the intake the ball is rotating because of the roller so the ball pulls the tubing down and stretches to accommodate the ball. When the ball is on the other side however the tubing blocks the ball from leaving the intake, keeping it in the correct firing position and preventing the ball from rolling out.

It sounds really weird but it works really well.

Is this a change to your robot from Hub City? I do not completely understand. Do you have video of this in action?

Yes. We added it after balls rolled forward after the catapult at Hub City. I don't have any video now, but I'll see if I can get any at our next meeting.


Edit: Shelbers2486 posted their reasoning below. Ours was basically identical.

We added the tubing a few weeks ago when we realized the the ball would roll off the shooter into the pick up system if we were just driving around. It would take a few valuable seconds to get the ball back into the shooter every time we were ready to fire, so we grabbed a piece of tubing that was just sitting around and it worked perfectly!
