Nissan Brings Us Self-Driving……Chairs?

Jennifer van der Kleut

Japan may not have self-driving cars loose on public roads yet-but they at least have self-driving chairs.

Yes, we said chairs! In a new video uploaded to YouTube, Nissan shows off its latest creation-office chairs that reset themselves to their original position, tucked into a table or desk, at just the clap of your hands.

Nissan’s fancy, autonomous “smart chairs” can reset themselves either with or without a human sitting in them.

In a press release, Nissan explains the new technology behind the chairs, which they say was inspired by self-parking technology they are already working on in cars.

The system appears to function with sensors on each chair that pair up with wireless cameras placed on the room’s ceiling.

“The ‘Intelligent Parking Chair’ is a unique chair that automatically moves to a set position,” Nissan’s press release states. “The chair includes a roller to automatically move 360 degrees, paired with a system that indicates the target position. Four cameras placed on the room’s ceiling generate a bird’s-eye view to wirelessly transmit the chair’s position and its route to destination.”

When the chairs are empty, someone can clap their hands and all the chairs in the room will automatically guide themselves back into position at the table, as Nissan’s video illustrates.

When someone is in the chair, he or she appears to be able to use controls, similar to those on an electric wheelchair, to guide themself back into position at the table.

Though they call the self-parking chairs a “novelty,” Tech Times said, “It’s proof that autonomous vehicle technology has implications far beyond the automotive field.”

Tech Times points out that the smart chair technology could prove particularly valuable for large rooms like auditoriums and cafeterias.

Autonomous, Wireless-Charged Electrics in Google’s Trick Bag

Google is testing wireless charging systems for its electric-powered, driverless cars in California, according to several news outlets.

The systems use transmitters within a pad to send power to a receiver in the Google vehicle when it’s atop the pad. This recharges the vehicle, and reduces the need for heavy batteries that electric cars now use, according to IEEE Spectrum.

Google is working with providers Hevo Power and Momentum Dynamics on competing charging systems at two test areas – its Mountain View, Calif., headquarters, and Castle Commerce Center, a former Air Force base in Atwater.

Both Hevo and Momentum use resonant magnetic induction to transfer the power between the charger and the receiver in the vehicle, according to The Christian Science Monitor.

Hevo’s prototype charger, called Alpha, transmits 1.5 kilowatts of power from a circular device in the road. Momentum claims its wireless transmitters have power ratings up to 200 kWs.

The goal is to have the rechargers installed at intervals within the roadway itself so the vehicle is recharged as it is driven.

The street charging would eliminate the need to literally plug in to recharge an electric vehicle. That would make recharging virtually seamless for the blind, those with disabilities, and others that may find it difficult to fool around with plugs, cords and other equipment.

Google has said since it began its driverless project that it is trying to open up mobility for those who have found traditional transportation less than friendly.

Street charge theoretically also eliminates the ‘range anxiety’ that has scared off many potential electric car buyers.

Affordable hybrid-electrics like the Chevrolet Volt have a range of 53 miles when strictly electric powered but can travel more than 400 miles on a combined full tank of gas, fully charged motor.

Gizmag reported last August that Highways England would be testing in-road electric vehicle charging technology. Those tests were to be conducted at test tracks, and if successful, move to on-road trials.
