A new “eye” may radically change how robots see
The low-power robotics system LENS merges a brainlike sensor, a chip and an AI model
This hexapod robot recognizes its surroundings using a vision system that occupies less storage space than a single photo on your phone. Running the new system uses only 10 percent of the energy required by conventional location systems, researchers report in the June Science Robotics.
Such a low-power ‘eye’ could be extremely useful for robots involved in space and undersea exploration, as well as for drones or microrobots, such as those that examine the digestive tract, says roboticist Yulia Sandamirskaya of Zurich University of Applied Sciences, who was not involved in the study.
The system, known as LENS, consists of a sensor, a chip and a super-tiny AI model to learn and remember location. Key to the system is the chip and sensor combo, called Speck, a commercially available product from the company SynSense. Speck's visual sensor operates “more like the human eye” and is more efficient than a camera, says study coauthor Adam Hines, a bioroboticist at Queensland University of Technology in Brisbane, Australia.
Cameras capture everything in their visual field many times per second, even if nothing changes. Mainstream AI models excel at turning this huge pile of data into useful information. But the combo of camera and AI guzzles power. Determining location devours up to a third of a mobile robot's battery. “It is, frankly, insane that we got used to using cameras for robots,” Sandamirskaya says.
In contrast, the human eye detects primarily changes as we move through an environment. The brain then updates the image of what we're seeing based on those changes. Similarly, each pixel of Speck's eyelike sensor “only wakes up when it detects a change in brightness in the environment,” Hines says, so it tends to capture important structures, like edges. The information from the sensor feeds into a computer processor with digital components that act like spiking neurons in the brain, activating only as information arrives — a type of neuromorphic computing.
The sensor and chip work together with an AI model to process environmental data. The AI model developed by Hines' team is fundamentally different from popular ones used for chatbots and the like. It learns to recognize places not from a huge pile of visual data but by analyzing edges and other key visual information coming from the sensor.
This combo of a neuromorphic sensor, processor and AI model gives LENS its low-power superpower. “Radically new, power-efficient solutions for ... place recognition are needed, like LENS,” Sandamirskaya says.
What does Sandamirskaya's criticism of camera-based robotic vision imply about the trade-off between data richness and energy use in AI systems?

The Impact of Electric Vehicles on the Automotive Industry
Looking at the environmental, economical, and political impact of electric vehicles.
By Patrick Peterson of GoodCar
Electric vehicles (EVs) have had a remarkable glow-up in a relatively short period. It wasn't so long ago that public opinion labeled them as overpriced, inefficient options with poor mileage to boot.
However, rising climate concerns and the volatility of gas prices have pushed more people to refresh their understanding of the technology. While misinformation is rampant, people's faith in EVs has risen enough that over 40 percent of Americans would seriously consider making the switch.
Growing interest pressures manufacturers to reorganize their supply chains with a stronger emphasis on EVs. This sounds simple, but there are significant differences in EV development compared to gas-powered cars.
The longstanding dominance of gas-powered vehicles makes most people believe it was the only option up until now. But that's wrong. The idea of electric vehicles has been experimented with since the early 1800s.
Robert Anderson is credited for inventing the first electric vehicle. The Scottish inventor used primary cells (single-use batteries) to power a motor he fixed to a carriage. This idea for a "horseless carriage" was a pivotal moment in history that gave future inventors a foundation to work on.
Jump to today, and EVs have skyrocketed in popularity. They've proven to be a more sustainable option and have a lower overall cost than gas-powered cars.
Opponents of adopting EVs argue that battery-powered vehicles aren't entirely emission-free. And they're right. Carbon emissions are created during the manufacturing process and when charging the battery. This is because fossil fuels are required to mine the minerals used in batteries and to generate the power used to recharge them.
However, these emissions are substantially lower than those released by cars using an internal combustion engine. A study performed by MIT found that electric-powered cars created about 25 percent fewer carbon emissions per mile than a gasoline alternative.
This study even assumed the cars were in less eco-friendly states. When Washington was used as the backdrop, the study reported that an EV would create 61 percent fewer emissions. This is due to Washington drawing a lot of its energy from hydropower. Norway, Europe's biggest EV market, takes a similar approach.
Over half of Americans are willing to pay more for sustainably responsible products. A comparable number of citizens say the same thing about gasoline.
Manufacturers' supply and production procedures must start adapting now to prepare for the future. There are even various government incentives to make the process easier.
In the statement “This support for greener brands shows the automotive industry how the future will look”, what does the term “greener” most precisely imply?
