The fact that it can move like that is scary in itself. Also, with the new object detection and recognition softwares being developed, it's reasonable to say that there will be robots who can do parkour way better than any human could, on the fly.
We once made a robot for a competition that could detect when the opposing robot was within the correct range and angle for a shot to score a ball into its trailer (which was tied to the back of the opposing robot so it was moving in a none predicable pattern) solely by video input. It had around a 90% accuracy with its shots. If a bunch of high school students could do that 3 or 4 years ago I'm pretty sure its very very likely that extreme professionals could do this with randomized boxes
Go robot, go robot, remember us who supported you in the overthrow of humanity. Lol, seriously though, amazing technology advancement; but the true test will be to see if future designs will carry your pack or say "no, I just want to walk with nature for a while, and if you cant handle that just wait for me here... I'll be back."
How good is it as other paths and placements?
