The best example of a general purpose robot today I think is spot from Boston Dynamics that yellow quadripet that walks around. So we can do that for about at least the last time I heard it was 90 minutes. Yeah there's appendages now that have hands and so it can yeah it's really useful fed robots for a long time but they're very specific. This one you can tune to do lots of different things but it can only do it for 90 minutes. If a walrus is chasing me on the ground on the land. It's not catching me.
