Using Inventor I made an animation of a linear extending stage for a tray for Tower Takeover. I have put it on my Youtube page here or below in GIF format. It could be easily integrated into many existing tray designs.

This is so much better than the extending tray i have currently.

It was something that I felt many teams needed help with, and since I am now in need of doing this myself, I thought I might share.

I have thought about a system like this before, but never actually developed something. However, I do see a major drawback on this design. The back of it requires something to be pushed on in order to go higher. This would counteract many teams strategies to fill the ramp with cubes and then score them in the tower. It is definitely a solid design if you can work out that issue.

We have the 448-style arms, so that isn’t an issue.

Still, the ones where it falls off the top seem to be faster than the arms. Thought you can’t unscore towers.
The bots that dont have arms and arent dr4bs are probably simple trays, which have 1 spare motor left over to be used for tower scoring.
I was thinking of this
one downside I see this having that a flip out third stage doesn’t have is that you can’t cram an extra cube in. most trays can fit one more cube in, with the top cube sort of poking out of the top of the tray. you couldn’t do this with a slider, so you’re sacrificing one cube capacity.

3 stage tray + extension???
better make some good anti-tips lol. also idk if having a 4 stage tray is really worth it, do you really need to be stacking that tall?
That could be theoretically possible, but I had this in mind as a 3rd stage itself.
I plan on making a better version of this this afternoon that does not include linear slides, which add a crazy amount of weight.

To be honest this isn’t a bad concept for a sliding tray, but I would very much recommend teams to consider making custom slides from spacers and channels / halfcuts as they weigh much less compared to steel rails. Other than that, I love the animation!
Yep! I will make a better version this afternoon.

What are 448 style arms?
He’s referring to a 2-bar system to score in towers.
Ah gotcha

I just noticed that this team uses the design you are mentioning here. You might want to ask them for any challenges while implementing it, or just see them in action.
