Yeah, the humanoid acrobatics are very impressive... They've made a helluva lot of progress since the first teetering/wobbly/unbalanced steps that I remember...
But I thought I'd start this thread with the doggie-bots... perhaps because it's so easy to imagine a real-world use for them: maybe as "watchdogs" that patrol a property at night, beaming security video back to property owners or law enforcement... etc. etc.
