Teaser 1:
[ATTACH]8908[/ATTACH]
Double reverse 4 bar. Can’t see any intake from this angle.
All aluminum DR4B
4-393 @ 1:7 Ratio
Dual rubberband assist
Conveyor belt Intake
That’s all I can tell from here…
That gearing seems a bit unconventional. It couldn’t work if the gears were fixed to the axles, so it must use all green inserts allowing both gears to spin.
The difference between this and normal DR4B is that the two 4Bs will not maintain the same angle relation to each other. They are essentially powered separately. Since the lower stage has to lift more weight, the two motors on the lower section might struggle more and lift slower, meaning the top half will lift faster.
I’m guessing there’s a particular reason you wanted to implement this into your design, since it is displayed so prominently here in the teaser.
Looks like there are some tank treads in there. Possible the conveyor cube intake?
Are those high strength gears? Looks similar to a reverse double 6 bar one of our team mates are building.
Yes, they seem to be the new high strength 84 tooth gears.
Yes, the gearing seems weird 
it looks like there will be a ton of friction because of those green inserts (or maybe we built our rd4b wrong).
Another thing that interests me is the bar on the top left. I can’t tell if it’s part of the hooks or a swivel or something else.
The treads also are vertical or close to vertical at some point. Triangle shaped conveyor?
That could be correct. One of my club’s teams has a triangle shaped conveyor intake which gives them an extra cube capacity.
that is brilliant!..
but impractical even with smooth inserts.
I feel like you wouldn’t lift as high crossing so close like that.
That’s a creative gearing setup, though I would agree that having the arms so close limits your height. It looks like you may have gear skipping issues with those longer axles, though.
