As a figure skater and AI engineer, that venn diagram of my life doesn't often overlap.
That was an interesting paper but I'm confused as to what they actually tried to achieve. I'm also confused how they achieve any turning in a model that has infinite friction on one side and zero friction on the other. My brain is having trouble understanding how such a model could ever achieve anything other than a straight line.
I’m guess it’s implied that this is only while the skate is in contact with the ice, and that the skate is lifted in order to reposition it? It seems a rather inadequate model if we want to train a halfway competent ice skating robot, though.
You can still draw arcs without sideways slipping. If you do out the math, you’ll see that a skater traveling in a circle has no sideways velocity, but does have sideways acceleration.
Hi fellow figure skaters , we started an event that fits this venn diagram in 2020. Our organization (SVISA) was started by a group of techies in the SF Bay area to save local ice rinks. Here's some more info on our STEM Ice event & group:

Hello fellow figure skater! This is a fun intersection to find on HN
