If a hook were added on the feet it could hang upside-down like a bat, hanging like that would save power. Also wheels extentions could be added on the calfs and shins that fold down similar to SpaceX lading legs to use gravity on hills and mountains to propel it forward extending its effective range. Perhaps using the turning of the wheels to either store energy in the wheels in a spring for a boost to the wheels or convert to electric to extend the battery life

Leonardo's control systems and stability are very good. As for the practical use, he can be like a patrol drone on mountains. Ex- 2013's floods in Uttarakhand killed hundreds and misplaced thousands. In such situation, a more robust drone like Leonardo could help in patroling the mountains quicker than a full size Helicopter. In the rescue effort of the floods, some rescue helicopters also crashed. So a larger more heavily built Leonardo robot cna definitely do such jobs and provide surveillance safely. 💯

[@mastercheatcomplete]

the question that was bugging me the entire video was how does having propellers working all the time to maintain balance affect the battery consumption... I mean, it must be less power than actually flying, but at the same time, seems like more power draw than simply shifting weight to maintain balance... So the question is - is this the best of both worlds (drones and legged robots), or a lame combination that essentially won't be optimal for any particular job

[@montithered4741]

One way I see the rotors used is as gyroscopes for stability. Walking robots have multiple gyros constantly spinning for stability and control. Adding propellors to the gyros adds additional functionality. There is also the flexibility, versatility, and redundancy of multiple modes of locomotion; lighter bipedal robots with rotors for flight and perching, quadrupedal plus rotors for heavier loads and jumping.

[@the1exnay]

@@montithered4741 but propellers consume more energy than a dedicated gyroscope. I suspect a lot more energy

[@jakegarrett8109]

@@montithered4741 gyros should have very low power draw, they aren't doing work. Propellers as you noticed were being spazzed on and off constantly to account for poor balance, so now your gyro would be having a siezure spiking up and down which probably is going to do more harm than having nothing because now you have insanely sporadic amounts of rotating inertial changes and slower to respond thrust because now it's acting like lead props.

[@raztaz826]

Well,..once they want to carry something that is too heavy to just fly away with, then the legs will be useful. To use legs only for balancing like the Atlas or Spot robots from Boston Dynamics is very difficult. So it is a cheap and easy way to balance, without as much sensors, computing power etc. If you stand on 1 leg holding a heavy thing, you may fall, but just 1 finger touching a wall and it becomes easier, but your finger isn't bearing all the weight. So this robot could for example fly to an island, move some bricks around which are too heavy to lift by flying, and come back (why.. idk).

[@darrenfalconer3267]

The noise can be brought down using various factors. Size, quantity etc Just depends on how much thrust needs to be generated with the propeller (s) used

[@jbleach23]

I was just thinking the same

[@AaronSchwarz42]

One way, to make all the blade of a 5+ blade rotor slightly different shapes (sound different for each) & still rotationally balanced // with very similar drag for each blade (a really hard design challenge that CAE tools can help with, though making it the really hard part, especially balancing it perfectly in a way that can hold tight while spinning at very high RPM //

[@tomc.5704]

For real. Maybe the guys designing fans for Major Hardware could work on that

[@MadDragon75]

The sound of the props can be manipulated by the pitch of the blades. More aggressive pitch gives more thrust and create more turbulence.

[@loganchow2989]

As someone who dabbles in slack lining, it’s interesting how Leonardo bounces on the line, which I’ve found is a helpful technique for humans as well. Bouncing negates some of the side-to-side movement of the line, and allows you to stay more upright and stable. Once you get better, you learn to ride with the line, but as a beginner, bouncing definitely helps you to learn.

[@greg.peepeeface]

I’m blown away by anybody who can do slack line

[@Alkatross]

Is slacklining easier if you wear heels like Leonardo?

[@rasmasyean]

Seems like by "bouncing", you're creating creating vertical force along your long axis (where the moment is smaller), and avoiding the horizontal force at your legs, which is much further from your center of mass (where the moment is much larger and can tilt your body easily).

Propellers kill the batteries rapidly; they need to be integrated as a last resort for balance and engaged when it comes close to its tipping point; instead, perhaps tweak the ZMP and/or DSC algorithms. Of course this is easy for me to say behind a keyboard. Great concept though and yes add some wheels that can be activated when needing to.

[@mondeepgohain7412]

It looks like what makes this a compete design is whether parts can be redundant meaning it can self correct itself if it breaks a leg or a fan. Also the video did not mention whether there was any gyroscopic stabilization going on.

[@benc1927]

Its neat, but when I watch Boston Dynamics robots deal with an unexpected event (being knocked over, down or bumped) it is able to reset and right itself back up. With these, their unprotected propellers would be damaged in the event of being knocked over or accidently bumping in to something (branch, small strings or twine etc) And at that point would need a human to intervene to assist it.

[@JuniusJones]

I would expect a protective shroud in a future design.

[@urbanmentalterrorist]

It’s rapid prototyping, you wouldn’t build that onto a prototype because it’s not 100% necessary to the conceptual design and it may change the aerodynamics when they are testing to see if the thing even works in the first place. It’s also why the back is exposed as well.

[@benc1927]

@@JuniusJones Sure, but it will still get knocked over. How does it get back up when knocked over (assuming the added weight of the blade shrouds didn't get fouled up) Ultimately this will have a limited niche use application as it does two things poorly. Walking and flying, both of which a dedicated walknig drone and flying drone could achieve more easily. Blending the two is interesting, but long term limited.

[@temporal_paradox]

7:07 Very impressive robot, but this point is debatable. There is clearly weight on the rope, but how much? I'd argue that it's comparable to lifting yourself up in your office chair and wheeling around with your feet Flintstones style - the propellers (arms) are likely doing most of the work. It's hard to discern as an outside observer exactly how often the legs are actually supporting the weight. My assumption is that most of the time, the robot is nearly neutrally buoyant, like diving down and walking along the bottom of a pool.

[@pvic6959]

im sure the researchers and engineers have telemetry data they can look at. the robot is 100% logging how much weight its feeling and stuff

[@sheldonaubut]

Plus there was a guy in the background of most shots operating a normal R/C plane/drone controller. So, how much control did the "robot" actually have.

[@appa609]

yeah. Anyone can slackline underwater

[@RenshawYT]

@@sheldonaubut It's possible that is some sort of safety cutoff. Since the robot has no tethers, you'd need a remote way to cut power or otherwise disable it if it was doing something dangerous (to itself, or anything else.)

[@pistonsoup3749]

It's probobly very similar to a drone, a drone can not fly without a control algorithm. But still uses a controller to take care of things like position and direction control.
