Anyone know a way to get a ball under a competition pole w/ a rubber band intake?
Thanks
I would try to avoid it. If it’s under a pole, it’s border-line in the goal. The game officials could try and call you on descoring depending on how far into the plane of the goal the ball is.
A c channel can get balls out.
If you just have part of your robot stick out a bit, you can push them out
I agree with this, unless it is blatantly sticking out, just don’t go for it, and if part of your robot sticks out a bit you run the risk of entering the plane of the goal
With a horizontal feeding mechanism, you could make it low enough to go underneath the bar and suck the balls but be careful of descoring and breaking the plane and pushing the balls into the low goal.
Has anyone made an intake designed for that purpose? If so, which team?
Also, I wouldn’t recommend the extended C-channel just because if the balls are not past the line you can usually push it back from the bar with just the corner of your bot (if your low enough of course) .
Maybe someone could make a device that sticks out an inch and a half off the side of their robot that scoops the balls out.
It is illegal to descore. If a ball is stuck under the bar, it is most likely scored, thus picking it up would be illegal.
if a ball rolls toward the bar it gets lodged in there a little bit, but it isnt touching the white line so it isnt scored. I believe those balls are the ones that @Toodalido is looking to intake.
But it would be almost impossible to see them from where you are controlling your robot from. It’s a risk you probably shouldn’t take
I do not currently have access to a field, but I believe any ball that rolls under the bar would be touching the tape, thus, scored. At the very least, as @ThunderRobotics says, it would be impossible to tell from the driver station.
I know for a fact that a ball that simply rolls into the bar does not touch the tape and, therfore, is not scored in the low goal. However, the moment a robot pushes it further under it does touch the white tape. It just takes a little bit of force to make it into the low goal, but rolling does not have enough force to do that.
It would be pretty easy to make your feeding mechanism only able to pick up balls that aren’t scored already.
This wouldn’t be that effective though, in matches i was in yesterday there were an average of 2-4 balls that were in the low goal.
In matches yesterday, most of the matches still had balls on the field. In worlds almost all of the matches will have no balls on the field and after the field is cleared and the driverloads shot, you might have a few more seconds to go for those potentially match affecting 2-4 balls if you aren’t planning on lifting or getting lifted.
Let me rephrase that, in the competitive matches ie: the semifinals matches yesterday there were only a few balls left on the field if any in a few matches. Only the very good teams would need to make an intake like this and it wouldn’t even be that beneficial since they already have a more efficient intake
