@ari @liaizon If by cord you meant not just the copper but a power supply, you should still be careful. I think it's hard to destroy a device with too little voltage, but for the 15V one, your device might draw too much current and destroy the power supply.

19V might fry your device though, depends.

@neauoire I love the swap dragon. Also, the execution train. Great book.

@blinry I use this, which is nice, because I didn't have to establish a new habit - I already brush my teeth twice a day!

How to solve a problem the German way:

1️⃣ build a new bike path
2️⃣ block the pavement with equipment for air-pollution monitoring
3️⃣ do not reduce car traffic, but put six huge vacuum cleaners next to the monitoring station onto the bike path
4️⃣ set up 14 traffic signs that legalize riding on the pavement, whereever a vacuum cleaner blocks the bike path.
5️⃣ problem solved! SUCCESS!

@mntmn derp, don't mind me, I didn't actually look at the entire page, just half-remembered (wrongly) that the transparent base plates were a limited thing.

@mntmn any chance you'll offer the nice acrylic base plate you had on some early backer units as an option?

@ticky mine hasn't been connecting to The Online at all (not enough to show "live" Drivatars, anyway) in a while. I was thinking maybe it's the PiHole I have set up in my home network, but maybe the servers are just... bad?

@mdhughes @polychrome That said, of course you don't need that flexibility if you can have multiple, radically simpler, purpose-built robots, which is something that BD is discovering with Stretch.

@mdhughes @polychrome wheels are easier to design, build, operate and maintain, and use less power than legs, so there's tons of points in their favor.
But ultimately, offices (and many other places) are built by humans, for humans, so humanoid robots are going to have the most flexibility in traversing/using these environments.

@mdhughes @polychrome thanks for explaining! that makes sense, although I don't 100% agree on "wheels are more useful in an office". I have counterarguments in both directions:
a) almost everything we've ever sent to other planets has been wheeled
b) spaces designed for humans very quickly become very wheel-unfriendly. stairs are the most obvious, but even relatively small thresholds + other things that don't fit a single toot

@mdhughes @polychrome genuinely curious: what aspect of BD robots would you say is "predatory"?

@polychrome @mdhughes I also think it's interesting that that bomb disposal robot (variants of which are also used by the military) might well have been made by iRobot ( - y'know, the Roomba people. I don't think they catch nearly the amount of flak BD does, though 🤔

@polychrome I don't think any of their robots were ever really anywhere close to battlefield ready (BigDog was too noisy for the kinds of missions it was pitched for, ATLAS and Petman I don't think would be "smart" enough to make decisions on their own beyond traversal), except maybe for sand flea

@polychrome Also worth noting that ATLAS' most prominent application so far was the Darpa Robotics Challenge, which modeled rescue, rather than combat scenarios. The results from that are also telling: Although obviously, some skills are bound to carry over, every ATLAS in that competition was meticulously, slowly, teleoperated (with heavy assistance from on-board systems, of course, but still).
