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.

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

hey, a fellow figure skater!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.

As a figure skater and AI engineer, that venn diagram of my life doesn&#x27;t often overlap.That was an interesting paper but I&#x27;m confused as to what they actually tried to achieve. I&#x27;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.

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&#x27;s some more info on our STEM Ice event &amp; group:www.robotsonice.orgwww.sv-isa.orgIf this interests you, join our mailing list, swing by, or dm me!
