Re: pic: 7.5" tall robot, ready to shoot
So would this theoretical robot be able to cross under the low bar while holding a ball? It seems like in order to do anything useful it needs to be in the taller position.

I like it.
I brought up a "collapsing" shooter idea after build season, as a side project. My team all shook their heads. :rolleyes: |
Re: pic: 7.5" tall robot, ready to shoot
Is there anything locking the shooter in position when it is in the firing position? It seems at least plausible that the ball being forced into the shooter could cause the shooter to give a little bit while firing, and generally you want all the rigidity you can get with such a system for consistency reasons.
I like the intake and shooter articulating together as it probably adds a lot of consistency to the ball loading. Just curious - how are you avoiding this mechanism tangling with the battery cable when it folds up? |

Battery cable- whats that? I see no cables... Realistically though, the battery wires can easily just go down the sides of the battery without hitting anything or risking a nasty break. |

According to the rules, the ball has a diameter of 10". I just wanted to know if the intake folds up or something and the robot chassis itself? Just a clarifying question. :D

Love the battery packaging.

I don't see any clearance for a tube fitting on your hood cylinders(picture). As it stands, you'll only be able to supply air to the retract side of the cylinder. It looks like you might have enough room to just space your shooter bearing plates a little more to clear a fitting, but I haven't looked at the CAD closely enough to see if this is possible.
Other than that, I really like the usage of the four-bar. I love seeing neat linkages on robots. |

I think I can push the mounting plates out by another 3/8" at least, or add a hole to allow the fitting in. Thank you! |

Re: pic: 7.5" tall robot, ready to shoot
How well would those little read Mecanum wheels on the side of the intake work for directing balls closer to the intake? Do they make a noticeable improvement for ball collection?

With this robot, what would your starting configuration be? (Aka, are you able to hold a boulder, while still being within frame perimeter?)

You can definitely make this work with a longer or shorter cylinder, don't forget you don't have to actually use the full travel of a cylinder (and can externally set the travel). You'd want some mechanical adjustment of shooter position anyway so that you're not remaking parts to tune shots (separate from what you can achieve with software). |

All of my trials I did with a layout sketch like you did in your RAMP video (great series BTW). I tried with 3.5" but found that I would be unable to flip the hood to the two positions I wanted, and 4" would make it impossible to mount. If I have changed the place where it attached to the hood, it may have been possible to use a shorter cylinder, only moving the cylinder forward caused an interference with something else while folded. If I had used a custom cylinder extension rod I would have gone a lot farther, but I figured it would be easier to just order the customs. I wasn't thinking about the turnaround while I was making this. If I had, I probably would have opted to move the hood-side cylinder mount closer to the hood pivot, even though it would have taken extra layout work. |
Re: pic: 7.5" tall robot, ready to shoot
Are there any tensioners on the shooter belt that runs through the tube? If so could I get a look at it?
