I can't give an answer which would pass a proper roboticist without them wrinkling their nose, but my guess is that rotary actuators are more simple and space efficient to implement, and can generate the necessary high torques for thes

Eh, robots are tools, and like most, they'll be used and abused. ANYmal and Boston Dynamics Spot are currently being used for automated site inspections, and most of the top spots for the recent DARPA subterranean challenge were legged

In this case, "Dynamic" is likely referring to the fact that the robot is dynamic, not the company Boston Dynamics. In fact, Dynamics is literally just the study of forces and their effect on motion, so I feel like it would be a s

I'm not sure any of the big legged robots are using direct drive actuation yet; MIT Cheetah and Cheetah mini use quasi-direct drives with a sub-10:1 gear ratio for super high proprioceptive sensing. ANYmal actually uses series-elastic

From the article: > In her suit, Viola acknowledged writing most of the posts. But she denied being behind the anti-Muslim screed. That was critical to Sorokin’s decision to allow the libel and defamation part of Viola’s suit to proceed.

Parroting jimkleiber, I like the distinction between advertising in public and private spaces, although I suppose it would be a matter of being adamant that anywhere that isn't in a private building, isn't private space. > Ther

Performing the same though-exercise, I find myself with a different conclusion; I despise physical advertising. I hate driving down the high-way and seeing a massive billboard for who-even-cares interrupting the fields and forests. I don&#x

I'm building a quadruped robot a-la Boston Dynamics/MIT Cheetah. I'm not really happy with the state of legged robots in terms of affordability and performance. I've found there are two classes of robots; robots in the f

I'm a relatively new user to HN. I've greatly appreciated how much more civil the conversations tend to be when compared to reddit. I have noticed, however, that news submissions, especially those which do not inherently have a te

I'm assuming you're referring to how softly he tip-toes around events like the Tiananmen Square Protests or the massive famine during the Great Leap Forward? If so, I certainly agree with you and many of the Goodreads reviewers in

Thanks for the recommendation! I feel as though On China sacrificed detail to allow for greater scope, and it left me wanting for more information on certain periods.

If anyone is looking for a relatively digestible book on China, I can wholeheartedly recommend On China by Henry Kissinger [1]. While he does tend to meander at some points, it gives a solid introduction to China's recent history (arri

I'm not well versed in CPU design; how does a 3.1Ghz peak clock A14X outperform a 4.8GHz peak clock i9 [1]? The only thing that immediately comes to mind is a massive hypothetical instructions-per-clock advantage. [1]: https:/&#x
