Robot masters human balancing act

By translating a key human physical dynamic skill — maintaining whole-body balance — into a mathematical equation, the team was able to use the numerical formula to program their robot Mercury, which was built and tested over the course of six years. They calculated the margin of error necessary for the average person to lose one’s balance and fall when walking to be a simple figure — 2 centimeters.

“Essentially, we have developed a technique to teach autonomous robots how to maintain balance even when they are hit unexpectedly, or a force is applied without warning,” Sentis said. “This is a particularly valuable skill we as humans frequently use when navigating through large crowds.”

Sentis said their technique has been successful in dynamically balancing both bipeds without ankle control and full humanoid robots.

5 Sci-Fi Books Biotech Geeks Should Read Right Now

From space colonization to resurrection of dinosaurs to machine intelligence, the most awe-inspiring visions of humanity’s future are typically born from science fiction.

But among an abundance of time travel, superheroes, space adventures, and so forth, biotech remains underrepresented in the genre.

This selection highlights some outstanding works (new and not so new) to fill the sci-fi gap for biotech aficionados.

Scientists develop smart technology for synchronized 3D printing of concrete

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a technology whereby two robots can work in unison to 3D-print a concrete structure. This method of concurrent 3D printing, known as swarm printing, paves the way for a team of mobile robots to print even bigger structures in the future. Developed by Assistant Professor Pham Quang Cuong and his team at NTU’s Singapore Centre for 3D Printing, this new multi-robot technology is reported in Automation in Construction. The NTU scientist was also behind the Ikea Bot project earlier this year, in which two robots assembled an Ikea chair in about nine minutes.

Using a specially formulated cement mix suitable for 3D , this new development will allow for unique concrete designs currently impossible with conventional casting. Structures can also be produced on demand and in a much shorter period.

Currently, 3D-printing of large concrete structures requires huge printers that are larger in size than the printed objects, which is unfeasible since most construction sites have space constraints. Using multiple that can 3D print in sync means large structures and specially designed facades can be printed anywhere, as long as there is enough space for the robots to move around the work site.

The Cipher of Intelligence

If simulating the brain is proving tricky, why don’t we try decoding it?


“There’s a good reason the first flying machines weren’t mechanical bats: people tried that, and they were terrible.” — Dan Robitzski

In the current AI Spring, many people and corporations are betting big that the capabilities of deep learning algorithms will continue to improve as the algorithms are fed more data. Their faith is backed by the miracles performed by such algorithms: they can see, listen and do a thousand other things that were previously considered too difficult for AI.

Our guest for the third episode of the AGI Podcast, Pascal Kaufmann, is amongst those who believe such faith in deep learning is misplaced.

Safe, efficient self-driving cars could block walkable, livable communities

Almost exactly a decade ago, I was cycling in a bike lane when a car hit me from behind. Luckily, I suffered only a couple bruised ribs and some road rash. But ever since, I have felt my pulse rise when I hear a car coming up behind my bike.

As self-driving cars roll out, they’re already being billed as making me – and millions of American cyclists, pedestrians and vehicle passengers – safer.

As a driver and a cyclist, I initially welcomed the idea of self-driving cars that could detect nearby people and be programmed not to hit them, making the streets safer for everyone. Autonomous vehicles also seemed to provide attractive ways to use roads more efficiently and reduce the need for parking in our communities. People are certainly talking about how self-driving cars could help build more sustainable, livable, walkable and bikable communities.

Watch this humanoid robot install drywall

The HRP-5P is a humanoid robot from Japan’s Advanced Industrial Science and Technology institute that can perform common construction tasks including — as we see above — install drywall.

HRP-5P — maybe we can call it Herb? — uses environmental measurement, object detection and motion planning to perform various tasks. In this video we see it use small hooks to grab the wallboard and slide it off onto the floor. Then, with a bit of maneuvering, it’s able to place the board against the joists and drill them in place.

“By utilizing HRP-5P as a development platform of industry-academia collaboration, it is expected that research and development for practical use of humanoid robots in building construction sites and assembly of large structures such as aircraft and ships will be accelerated,” write the creators.
