I wonder whether the extra weight of a third, retractable/foldable leg would negate the power savings that could accrue from being able to switch to 3-wheeled mode when appropriate (thereby allowing the gyro to be spun down).

By gyro do you mean flywheel? Is there one in this robot?

There does not appear to be one in this robot, from what I am able to read about it. I think sometimes people assume there must be something like that to help balance.

This generalizes fixed 2-wheel dynamic balancers which mostly don’t have flywheels for stability either, the focus is on the dynamics of keeping the wheels under the center of gravity, or a bit offset when moving.

The novelty here is about switching between dynamic control policies while keeping them simple.


iRobot is now Chinese-owned.


Yet the current word list apparently doesn't include "Irish" (even though Welsh, Scots and Brits are all valid). ¯\_(ツ)_/¯


> That's also a lesson on how a closed economy (and open ones too, to some extent) can collapse based on a single actor controlling the rules. That's fair to learn.

A timely lesson!


Exactly! If you think about it, every meteorite has passed through 36,000 feet at some point!

We've had a serious problem with policy-making in this country for a loooooong time, stretching right back to when RIPA was drafted, nearly three decades ago.

With a few notable exceptions, the level of knowledge, expertise and understanding amongst government advisers and policy makers is abysmally low. c.f. https://jackgavigan.com/2015/11/23/how-well-advised-was-the-...

Maybe it’s time to revert to Javascript’s original name: LiveScript.


Revert it to a Lisp too


What, "JavaThcript"?


JavaScript is not Lisp.
