So it's been a while.
Sorry for not posting anything but I have a bad habit of not posting stuff until I've finished the robots, but I do realize that if I post things as I build along that would be more interesting and informative.
Anyways I decided to update my Vortice robot to version 4:

Wanted to change things a bit from the usual Vortice robots.
It's now using the same thickness of alu that I use for the flipper and spinner. Still way too thin, as I proved by my spinner just going through the stuff like nothing. Should probably use polycarb for the scoops as well, but I like the look of alu...
Luckly I originally designed the robot to have multiple front attachments, so a poly wedge isn't out of the question, along with some hinged metal forks/wedge so when upside down it's not without wedge.
Also as you can see I was not happy with the protruding bolts in the wedge, so I used countersunk bolts* and hammered them into the alu until they where flush. Less bits for spinners to bite.
* (originally not countersunk, but made them countersunk by using the pillar dril as cheapo lathe and a file. Recycling!)
Previously on the rear it had a smaller and steeper wedge, to have something to push with when upside down and for protection, but this time:

I decided to have no wedge or protection for the wheels, but to give the robot the ability to never lose traction with the floor if lifted to much from the front, and hope to always keep the front end facing the opponent.
That meant that I had to use the top and bottom poly plates to hold the sides together, this made the build more complicated, but I made it.

Also I had to change the wheels as the alu hubs where too heavy.
I used the same round rubber things that I ended up using in UpperCut, but with more holes for weight reduction.
They aren't that grippy, but none of my wheel solutions are. I know I will eventually try silicon thread, but not now.
Main problem with these wheels is that because the rubber things are not designed as wheels, they arent perfectly centered, so I had to try and sand them down to "close enough". I stopped at that before making things worse.
Not entirely happy with it have to say. The construction ended up being way more complicated that I wanted, it's basically an unnecessarily convoluted jigsaw puzzle.
All because I wanted to have this specific shape, and 6wd, and using no 3d printing.
But here it is finally in a state that I can call finished.
Right know the main three robots of my "team" are done (pusher, flipper, spinner), so next will probably be a walker.
Never made one so far, so it will be interesting.
Might revisit the crusher idea as well.
