Now we just need a Clifford the Big Red Dog robot.

I wonder how it determines the height to see if it can leap or not. I would think also it could be engineered to climb the side of the building by simply creating a triangle shape and motoring up the side or with some kind of suction.

  I am assuming that its not autonomous and the angle/thrust is either pre-programmed for the demo or is human operator controlled.

    I'm thinking just basic geometry and some rangefinders and other sensors. It needs to know how high off the ground its rangefinder is, and how far away the base of the target is. Once it knows that, it's some basic arithmetic to determine the height of its target landing area. Set a trajectory, charge for both the distance and height (and possibly to compensate for wind) and you're done. There's some implementation subtleties I'm sure, especially considering your launch surface may vary, but that's the gist of it.

I should caveat subsequent comments by saying that I would have given my childhood for this toy (and therein I would have learnt the meaning of irony too, but I digress). Anyway I am wondering what this could really be intended for. If it is indeed meant to carry a camera payload for cheap soldier surveillance, then I have an alternative suggestion: http://www.amazon.com/Parrot-AR-Drone-Quadricopter-Controlled-Android/dp/B003ZVSHB0 http://www.amazon.com/Parrot-AR-Drone-Quadricopter-Controlle.... This $298 quad-copter with two mounted cameras seems like it could do the job just fine. (Incidentally on the subject of cheap RC toys saving soldiers' lives and proving themselves viable short-term options: http://www.rccaraction.com/blog/2011/08/04/traxxas-rc-truck-saves-soldiers-lives-in-afghanistan/ http://www.rccaraction.com/blog/2011/08/04/traxxas-rc-truck-...). Anyway, especially with Petman (http://www.bostondynamics.com/robot_petman.html http://www.bostondynamics.com/robot_petman.html) purportedly being for chemical suit testing (which in my opinion is like saying crash dummies need to have guns and machine vision), Boston Dynamics has shown that it likes releasing potentially mid-path projects for other-than-ultimately-intended purposes (makes perfect sense from a testing perspective). So I wonder what Sand Flea could be working towards other than surveillance? 11 lbs./30 ft is not bad considering a quad copter of similar size would be probably max 4-6 lbs. So maybe they are gearing it up for heavier payloads. Nothing like the 400 lbs alpha dog carries (at that point, assuming similar tech, the Sand Flea would have to be big enough to basically just roll over single-story buildings), but perhaps an explosive payload or something in the neighborhood of 10-20 lbs.

  The Sand Flea would be able to monitor an area for far longer and is much quieter than a quadcopter. Also, the Sand Flea can enter buildings/caves, and likely carry a small munition load. The REF doesn't invest in things that aren't ready to go to the sandbox. I think this is far further along than mid-stage.
jwarzech 15y ago
All I could think of while watching it was 'its a parkour robot!'
- ajratner 15y ago
  Haha. Someone should do a web scrape of all parkour club directories, and then look at the intersection of that set with Boston Dynamics' team... could explain some things

This is a pretty cool robot and one I intend to copy at my earliest convenience! If they combine it with the Van der waal's [1] adhesion effect then you have a robot that should be a really good urban navigator. Funny story, I designed a robot based on the hopping principle for the first DARPA challenge (the one where you were in the desert trying to go from Barstow to Las Vegas) except that we ran into issues with the ground being too soft in places to reliably jump. And the fact that we had an on board compressor which both weighed too much and took too long to recharge the jump tanks, but other than that :-) [1] https://en.wikipedia.org/wiki/Van_der_Waals_force https://en.wikipedia.org/wiki/Van_der_Waals_force

  - ChuckMcM 15y ago
    And when that version comes out we'll have a product where someone throws a robot out the window, it jumps up on to a wall of a nearby building, and starts streaming back video of the area. Or, in the less fun case, it will jump on top of a vehicle where the armor is weakest and fire a shaped charge straight down.

    Nice. My friend did his PhD on gecko adhesives too[1]. He later built[2] a "six-legged" robot like Boston Dynamics' RHex 'bot[3].

  Do you have anything online about that robot? I thought of building a hopper/glider hybrid a few years back. It would basically work like a large grasshopper. Windup and release a spring to jump and at the apex of the curve release a small wing to glide. Lather. Rinse. Repeat. It was to be an experiment in solar powered robots that would use the spring as energy storage instead of a battery. Never built it; this has me thinking about it again, tho.
Artary3 15y ago
This is so awesome! I was a big fan of the Big Dog but this thing is slick and might be my new favorite robot!
slavak 15y ago
What, am I seriously the first one to say this? I don't care what this thing is supposed to be used for; I want one!
clarkmoody 15y ago
I think the most interesting thing about this robot is how it maneuvers while in flight. If you watch closely, you will see that the robot stabilizes into the 'flat' configuration before reaching the apex of its flight. Without stabilization, it would simply tumble end-over-end. I believe the robot uses its wheels as reaction wheels, adding the proper torques to the tumbling body to cancel out longitudinal angular velocities. There are not enough controls to cancel out rolling, if it launches wrong. The robot would need an internal lateral reaction wheel or CMG cluster for that.
mattbaker 15y ago
Doesn't the building jump look really fake to people? The image changes at 0:16 right before it pops up. I call bullshit.
- mlpqlm 15y ago
  I don't necessarily call bullshit, but I can't help but question what was cut out.
jonah 15y ago
Their RHex bot is pretty impressive too: http://www.youtube.com/watch?v=ISznqY3kESI http://www.youtube.com/watch?v=ISznqY3kESI

That's really cool and Boston Dynamics is amazing but there's most certainly not a 30ft jump in that video.
ChrisNorstrom 15y ago
Fantastic news, we are now one step closer to Pirate Bot / Wireless Internet Broadcasting robot that can circumvent internet shutdowns. As regulations clamp down on internet free speech and authorities give themselves the power to administer internet blackouts during protests. This is the best way to respond in order to re-balance power back to democracies and people. Now we need to make it a bit bigger and start working on the rechargeable battery pack, solar panel, kinect 3d camera, gps, and long range wireless router (the longest range wireless router allowable by law is a 1 watt router with a 1,200 foot range called Bountiful Router) but I'm sure you can extend the range much further with an illegal hacked version, and use repeater units to send signals further. Basically a rogue mars-rover for Earth that sends out pirate signals. The future is horrifyingly awesome.
