Legged robots can be more efficient, in theory.

Whenever you drive/walk in soft terrain, the wheel/leg is constantly climbing the ramp created by it sinking into the terrain. In a perfect system, this determines how much power you need to move. This is why trains are so efficient. A hard wheel on a hard rail has very little deflection -- so excellent efficiency.

Wheels have to climb that ramp for every inch of travel. Legs get to step forward and only take that penalty for each step. If everything else is the same, the legs win on soft terrain.

But everything else is never the same :-). The early legged vehicles used linear motions, which means you have these very long sliding surfaces. This is heavy and the drive system efficiency dominates over the terrain interaction efficiency. Add in the fact that you have multiple axis to drive and the weight and drive losses really add up.

Modern dog and human style walking robots are MUCH better on efficiency than those early designs. However, they require enough sensing and compute to dynamically balance. Legs can do things that wheels can't, but you have to have smart enough software to take advantage of that. The compute available for a high radiation environment is a fraction of what is in your smartwatch. Wheels are still winning on energy efficiency, but at least it's getting closer.

I worked on Dante at CMU and Marsokhod at NASA Ames; and was in the same group that developed Ambler.


> the ordered dosage of methylene blue was 1mg/kg/hr

That's 5X what is considered a safe dose.

Up to 2mg/kg/day is considered safe. Double that with care. But they were dosing every hour for days!


Watch out of patent problems. There was a major dust up between Sonos and Google over audio sync technology. Disclaimer: I've worked for both companies, but not on that


Very cool write up! I'm amazed that it's running on AAA batteries.

The introduction to SDR (software defined radio) is much appreciated.

Edit: defined, not designed

The nuanced answer to this is they have a first mover advantage and make a great robot. The point of the thread is that new development is much cheaper for folks to figure it out. Recyclers are the most entrepreneurial people you will ever meet. we’ll figure out some good uses for this stuff when it gets cheaper.


Super familiar. Thanks!


This talks about the "what" of the code, but you have to also convey the "why".

If you have a well understood problem space and a team that is up to speed on it, then the "why" is well established and the code is the "what".

However, there are often cases where the code is capturing a new area that isn't fully understood. You need to interleave an education of the "why" of the code.

I was once asked to clean up for release 10k lines of someone else's robotics kinematics library code. There weren't any comments, readmes, reference programs, or tests. It was just impenetrable, with no starting point, no way to test correctness, and no definition of terms. I talked to the programmer and he was completely proud of what he had done. The variable names were supposed to tell the story. To me it was a 10k piece puzzle with no picture! I punted that project and never worked with that programmer again.


That depends on if it's in the grass that the cows eat. They first researched iodine in cows because there isn't much iodine in the grass around the great lakes. This area was known as the "goiter belt".

Adding iodine to the cow's food made them healthier and that's how they estimated the dose for humans (mcg / kg).


Talon Speech recognition also includes mouseless options and eye tracking: https://talon.wiki/Quickstart/Hardware/tobii_5

Works on Mac, Windows, and Linux


I keep wondering how this compares to Zig and WASM?

Zig has a nicer syntax with fewer foot guns than C. It can also compile or link with C.


It would be really interesting if it was possible to use other languages which can be compiled to .so files. Will look into it!
