OpenAI Inc. demonstrated a one-handed robot solving a Rubik's Cube. Apparently the real breakthrough in this milestone was teaching the system to do the task in simulation. “While the video makes it easy to focus on the physical robot, the magic is mostly happening in simulation, and transferring things learned in simulation to the real world," writes Evan Ackerman in IEEE Spectrum:
The researchers point out that the method they’ve developed here is general purpose, and you can train a real-world robot to do pretty much any task that you can adequately simulate. You don’t need any real-world training at all, as long as your simulations are diverse enough, which is where the automatic domain randomization comes in. The long-term goal is to reduce the task specialization that’s inherent to most robots, which will help them be more useful and adaptable in real-world applications.
Inspired by the way plants grow, MIT researchers designed a flexible robot appendage that can work in tight spaces but is rigid enough to support heavy parts or twist tight screws. From MIT News: The appendage design is inspired by the way plants grow, which involves the transport of nutrients, in a fluidized form, up […]
Greg Olijnyk works as a 2D graphic designer, but his hobby is creating unbelievably wonderful 3D science fictional cardboard sculptures that sport motors and lights that animate them (some use photovoltaic cells for power, too).
Corridor produced this excellent parody of Boston Dynamics’ robots and the style of its promotional videos. It could be the trailer for a new Neill Blomkamp or Paul Verhoeven movie, but where the satire is immediately transformed into stress because there’s very little about it that seems unlikely or even beyond the fairly immediate future. […]
