   Specifically RealSense sends too much uncompressed depth data (>1 Gbit/s). A better approach would be to encapsulate perception and ML model inference in the end effector and only send robot commands over existing wired links. Wirel

   Many robot arms provide robust RS-485 and (in some cases) Ethernet and have all wires plumbed inside the arm (so, little to no maintenance). In certain non-critical cases (like, agriculture), wireless can be used too, for instance, when the

   This is a nice proof of concept, but it's not anywhere production-ready. For instance, this apple harvester is using UR5 robot arm. It's a very research-friendly robot that I like to work with, but it's nowhere ready for outd

   I work for Google for the 3rd time; 12+ years in total. It's first time when this issue is brought to my conscience. I think that the issue exists, but it's not due to the monorepo, it's due to the internal APIs changing. I l

   We tried Formlabs, of course. We could print fingers like these, but none of the materials we tried (about 10 different options) survived more than 1000 cycles. As I said, Carbon3d underappreciated, because everyone think "it's ju

   Carbon3d is an under-appreciated tech. Their materials are incredible. A few years ago, we successfully used their elastomeric polyurethane to build a soft robotics gripper ([1], [2]) and we've got an impressive durability rating of 50

   This comment ignores existence of Starlink that already proved the tech and business model, while also having a considerably lower cost to build the constellation than competition thanks to the reusability.

    re: regulation. This is the problem with fission. but not necessarily so with fusion. The reason is that unlike fission, where it's impossible to a small company to get a handle on fuel and build a fission plant in a less-regulated cou

    The most productive tools I built for non-programmers were using text UI. They were fast, clean, obvious to use. Turbo Pascal made it especially easy with good support for menus and windows / panes. Nowadays, terminals have no problem

    I agree that wasting so much energy is not good. But it would be amusing, if we end up getting fusion energy sooner because someone makes a business case to mine bitcoins with the produced energy.
