11-lb Robot Can Jump 30 Feet Into the Air 68

Ruvim writes "Boston Dynamics has developed a 'Sand Flea' 11-lb robot that drives like an RC car, but when it needs to, it can jump 30 feet into the air. An onboard stabilization system keeps it oriented during flight to improve the view from the video uplink and to control landings."

    You can see the camera do take cuts before it jumps most times. Either it's chargin' its laser and they cut for time, or it's got other issues. (it may take awhile to say, charge a compressed spring piston)

    Another possible angle is it may only be able to set up for the jump if it's right-side-up, and we never see it flipping itself over, so if it found itself upside-down, it could be in trouble?

    But those jumps are quite impressive. I got the impression though that it could only do one height of jump, like when you see it jump off the top of the building. I was expecting a short hop to get it off the edge, but it cranks way back and catapults way up and off. So it seems to have a ways to go, development-wise.

    Family or not, these are the people that should be loaded into the Soylent Green hoppers first, if they ever bring us to that state.

    Who are you joking? These are the people who will design the Soylent Green hoppers.

    Just to reiterate, I actually watched when it jumped from the top of the building to see if the height would be the same. The jump at the top of the building arced ~5 feet. Not near as high as the jump to get to the top.

    I have two words for you: significant figures. Everything else is just noise...metric noise.

    Aghnnn! I'm not at all at ease with having the number of digits written out signify the uncertainty. That's just not very elegant. By that method, you can only express certain ranges (for example "1.45 to 1.55", but neither "1.44 to 1.54" nor "-5 to 17") and it's even dependent on what base you write in! Rather, give uncertainty as a separate number.

    Even more sophisticated would be to specify a probability distribution over possible values, but in the above discussion I assume that one wished to express the uncertainty as a range with sharp boundaries.

    In case anyone wonders, I do myself practise the "significant digits" method when the social context calls for it and I want to please people (so that they give me money, for example), but whenever I can, I follow my heart and do what's right.

I've noticed several design suggestions in your code.
