The Sentinel is a robot designed to make police traffic stops safer

Any technology worth its silicon chips is born out of the desire to solve a problem. The spark which prompted the Sentinel Robotic System just happens to be more tragic than most.

“In July last year, there were two specific instances that really pushed us to develop this device,” Vaibhav Tadepalli, a researcher at Duke University, told Digital Trends. “On July 6, Philando Castile was shot during a traffic stop in front of his girlfriend and four-year-old daughter. Then, two days later, officer Michael Flamion was shot as he approached a vehicle during another traffic stop.”

What Tadepalli and Sentinel co-founder Chris Reyes, along with three others, set out to develop was a robot that could law enforcement with this sometimes dangerous task.

The idea is simple: An officer involved in a traffic stop presses a button on the central console of his or her vehicle. This deploys the Sentinel robot, which autonomously approaches the stopped car. It then raises a video display that serves as a two-way link between the officer and the driver of said traffic stop vehicle.

The officer can request that the driver holds up their license and ID, and then scan this from the safety of their own vehicle. The robot can also perform breathalyzer and THC tests. If the officer deems the driver to be safe, they can exit their vehicle and proceed as normal.

If it turns out that the person pulled over has previous violent convictions, or a warrant out for their arrest, they can make an informed decision without putting themselves into harm’s way.

“Everything we looked at that tried to solve a similar problem focused on recording what happens,” Tadepalli continued. “For example, there’s been a lot of work put into body cams. Then there’s another company called Blue Eyes, which deploys drones to provide an elevated view of what’s happening. But there was nothing we could find that would keep officers out of danger. In every scenario, officers still needed to exit their cars and walk up to the window of the car they had pulled over.”

At present, the team behind the Sentinel Robotic System is raising the money to further develop the idea. If you’re interested in supporting it, can do so by pledging on Indiegogo, where contributing to the $7,500 goal can gain you a project sticker, T-shirt, scale model of Sentinel, or even the ability to name one of the bots.

This omelet-making robot chef is a sci-fi dream come true

Can robots make omelettes?

Would we think more fondly of the Skynet robot takeover if the Terminators cooked us breakfast first? Researchers from the U.K.’s renowned University of Cambridge are putting that hypothesis to the test (kind of) by training a robot to prepare an omelet -- from cracking the eggs through to plating up the finished dish. And, according to its creators, the robo-omelet actually tastes pretty darn good.

EVs top gas cars in German reliability report — but one weak spot won’t quit
future electric cars 2021 volkswagen id4 official 32

Electric vehicles are quietly crushing old stereotypes about being delicate or unreliable, and the data now backs it up in a big way. According to Germany’s ADAC — Europe’s largest roadside assistance provider — EVs are actually more reliable than their internal combustion engine (ICE) counterparts. And this isn’t just a small study — it’s based on a staggering 3.6 million breakdowns in 2024 alone.
For cars registered between 2020 and 2022, EVs averaged just 4.2 breakdowns per 1,000 vehicles, while ICE cars saw more than double that, at 10.4 per 1,000. Even with more EVs hitting the road, they only accounted for 1.2% of total breakdowns — a big win for the battery-powered crowd.
Among standout performers, some cars delivered exceptionally low breakdown rates. The Audi A4 clocked in at just 0.4 breakdowns per 1,000 vehicles for 2022 models, with Tesla’s Model 3 right behind at 0.5. The Volkswagen ID.4, another popular EV, also impressed with a rate of 1.0 – as did the Mitsubishi Eclipse Cross at 1.3. On the flip side, there were some major outliers: the Hyundai Ioniq 5 showed a surprisingly high 22.4 breakdowns per 1,000 vehicles for its 2022 models, while the hybrid Toyota RAV4 posted 18.4.
Interestingly, the most common issue for both EVs and ICE vehicles was exactly the same: the humble 12-volt battery. Despite all the futuristic tech in EVs, it’s this old-school component that causes 50% of all EV breakdowns, and 45% for gas-powered cars. Meanwhile, EVs shine in categories like engine management and electrical systems — areas where traditional engines are more complex and failure-prone.
But EVs aren’t completely flawless. They had a slightly higher rate of tire-related issues — 1.3 breakdowns per 1,000 vehicles compared to 0.9 for ICE cars. That could be due to their heavier weight and high torque, which can accelerate tire wear. Still, this trend is fading in newer EVs as tire tech and vehicle calibration improve.
Now, zooming out beyond Germany: a 2024 Consumer Reports study in the U.S. painted a different picture. It found that EVs, especially newer models, had more reliability issues than gas cars, citing tech glitches and inconsistent build quality. But it’s worth noting that the American data focused more on owner-reported problems, not just roadside breakdowns.
So, while the long-term story is still developing, especially for older EVs, Germany’s data suggests that when it comes to simply keeping you on the road, EVs are pulling ahead — quietly, efficiently, and with far fewer breakdowns than you might expect.
