I never heard of HASEL artificial muscles and just looked them up. Very interesting! But the main downside seems to be the high voltage requirement. Hopefully there are more innovations in the space of robotic actuators. I hate that servos usually are not compliant and rather are controlled by position and not by torque / force. I believe active compliance is not a real replacement for passive compliance in most use cases

I took this graduate course, which I think did a good job covering more advanced / modern CV approaches: https://web.eecs.umich.edu/~ahowens/eecs504/w20/ The python notebooks are locked, but the slides & recommended reading materials are freely available.

There is a startup called slamcore doing this in London. They've some interesting talks with the founder on their site.
