Ohio robot cop retires after zero arrests
NEWYou can now listen to Fox News articles!
Dublin, Ohio, gave a robot cop a trial run inside a public parking garage. Less than a year later, the machine was off the job and headed back to its maker.
DubBot, a Knightscope security robot used by the Dublin Police Department, was meant to help deter crime, support emergency response and give the city another way to monitor a busy public space. However, its patrols led to zero arrests, tickets or criminal cases.
Now the failed pilot raises a bigger question nationwide. Should local leaders have to prove these machines work before putting them on patrol?

Ohio robot cop ends its parking garage patrol
DubBot began patrolling the Rock Cress Parking Garage in July 2025. The robot was one of Knightscope’s K5 Autonomous Security Robots, the tall white security machines built to move through public spaces and act as an extra set of eyes.
Dublin retired DubBot on May 12 after deciding the pilot no longer fit the city’s operational needs. The robot has since gone back to Knightscope.
The city’s public safety page now says the autonomous safety robot pilot has ended. It also notes that Dublin added other security measures at the Rock Cress garage, including entrance and exit gate arms and mirrors.
What the Ohio robot cop was supposed to do
DubBot was designed to support police operations, deter crime and give people another way to reach emergency help. The robot had 360-degree video cameras, two-way emergency communication and an emergency call button that could connect people with dispatchers.
In theory, that sounds useful. A robot moving through a parking garage could make people feel watched over. It could also give police a live look at an area without assigning an officer there full time.
WHEELED, RUGGED ROBOT DOG BUILT FOR EXTREME INDUSTRIAL MISSIONS
But let’s be real here. A camera on wheels still has to solve a real problem. Parking garages have awkward corners, quick encounters and plenty of moments where something can happen fast. A robot moving at walking speed may create a visible presence. However, presence alone does not equal public safety results.
How much the Ohio robot cop cost
Dublin spent $128,080 in the first year of the agreement. The city expects a reimbursement from Knightscope of about $60,500, bringing the final cost down to $67,548.
The original plan was larger. Dublin had planned to pay $238,440 for two robots over two years. However, the second robot never rolled out. It was supposed to serve Riverside Crossing Park, but development needs and infrastructure limits kept it from going into service.
SMART STREET SENSORS COULD BE WATCHING YOUR CITY NEXT
That leaves one robot, one parking garage and a pilot that ended with no arrests, no criminal cases and no tickets.
The city also collected no other performance metrics because the pilot was meant to test the robot before any expansion.
That part should make taxpayers pause. When a city tests an expensive public safety tool, people deserve a clear way to judge whether it worked.
US TARGETS CHINESE ROBOTS OVER SECURITY FEARS
Why cities keep testing robot cops
You can understand why local governments keep looking at these robots. Police departments are stretched. Public spaces need coverage. Parking garages, parks and transit hubs can be hard to monitor with people alone.
Security robots promise a lot. They can move around, stream video, offer a help button and act as a visible deterrent. They also give a city a technology-forward image, which can sound appealing during a public safety pitch.
The challenge comes after the rollout. When a city says a robot deters crime, officials should explain how they will measure deterrence. When the robot supports emergency response, the city should track how often people use the help button. When the robot helps investigations, officials should show whether its video helped solve cases. Without that kind of follow-up, a robot can become a pricey symbol rather than a useful safety tool.
HUMANOID ROBOTS JUST GOT A WORKPLACE SAFETY SYSTEM
Other robot cop pilots have struggled too
Dublin is hardly the only city to test a Knightscope K5 and then move on. New York City tried a K5 robot in the Times Square subway station. That pilot ended after several months. Reports at the time noted that officers had to chaperone the robot and that the machine could not use stairs.
San Antonio International Airport also tested a Knightscope robot. That trial ran into technical problems, including navigation issues, camera focus problems and trouble with live video and audio feeds.
Those cases do not prove that every security robot will fail. They do show that public spaces are tough testing grounds. A robot may look impressive in a demo, then struggle when crowds, tight spaces, doors, stairs and real people get involved.

Robot cops raise privacy questions
The other issue here is privacy. Dublin has a broader public safety technology program that includes drones, license plate readers, security cameras, body-worn cameras and facial recognition technology under a formal policy. Add a roaming robot with cameras and emergency communication, and residents may have fair questions.
What does the robot record? Who can access the footage? How long does the city keep it? Does the system use facial recognition? What happens when someone presses the emergency button? What data goes to the company?
Cities should answer those questions before a robot starts patrolling public spaces. The point isn’t to reject every new tool. The point is to make sure public safety tech comes with public accountability.
AI DASHCAMS ENHANCE TRUCKER SAFETY WHILE RAISING PRIVACY CONCERNS
What this means to you
If a robot starts patrolling your local garage, mall, park or transit hub, do not get distracted by the cool tech factor. The first question should be: What does it actually do when something goes wrong?
Can it connect you to a real person fast? Is someone watching the video when it matters? Can it help during an emergency, or does it mostly record what has already happened?
But let’s be real here. If your tax dollars are paying for this kind of technology, your city should explain the goal before the robot rolls out. Otherwise, people may only learn whether it worked after the money has already been spent. New technology can sound impressive. However, results still count.

Kurt’s key takeaways
A robot cop patrolled a parking garage, led to zero arrests and then got sent back. That should make taxpayers ask some hard questions. But let’s be real here. If local leaders are paying for AI-powered public safety tools, they should explain what problem the tech solves, how success will be measured and what happens to the data it collects. Dublin deserves credit for ending the pilot when DubBot failed to deliver enough value. A robot can look like progress, but the real test is whether it makes people safer and gives taxpayers results they can actually see.

Dave Eggers told OpenAI staff that ChatGPT was ‘silencing an entire generation’
Last year, Sam Altman invited author Dave Eggers to give a talk to around 200 OpenAI staffers. The man has written countless novels, screenplays, pieces of journalism, started McSweeney’s, and founded multiple schools and nonprofits that support writers and the arts more broadly. So one might expect he’d roll into the company’s offices and offer tips on being relentlessly prolific, or how to excel in multiple fields. Instead, he apparently laced into the company. According to the Financial Times, Eggers told the staff:
“The effect of ChatGPT on educators’ lives is catastrophic. Whether you intended to do it or not, you’ve made every teacher’s life infinitely more difficult than it was two years ago. So, just let that settle in… If students are using it to compose, which is the biggest tragedy of all, they’ll never learn to write. And their voice is stolen from them. They’ll never have the ability to say their truth and tell their own story. And that’s silencing an entire generation or two.”
To be fair, Altman likely knew what he was getting himself into. Eggers’ best-selling novel The Circle is a scathing critique of the tech industry. And he’s called AI-generated writing “pastiche nonsense.”

How to share vacation photos on any screen
NEWYou can now listen to Fox News articles!
We have all been there. You come home from a trip, someone asks to see the photos, and suddenly your phone is making its way around the room, one person at a time. That works for a few snapshots. It gets old fast when you have beach videos, family group shots, mountain views or that one ridiculous restaurant photo everyone needs to see.
The better move is to put your vacation photos on a bigger screen. You can use a TV, projector, laptop, tablet or even an outdoor screen. The right method depends on what phone you have, what screen is nearby and whether you are at your house or someone else’s. Here are the easiest ways to share vacation photos without turning your phone into a handoff relay.

HOW TO SAVE ANY FILE AS A PDF

Start with the screen you already have
Before you mess with settings, look around the room. The best option may already be sitting in front of you. A smart TV works well for most people because it may support AirPlay, Chromecast, Smart View, Roku, Fire TV or screen mirroring. A laptop can also work if the TV connection gets messy. A tablet is great for a smaller group at the kitchen table. A projector gives you the biggest wow factor, especially outside.
If your TV is due for an upgrade, CyberGuy’s Top TVs of 2026 can help you find one with the features that make photo sharing easier. Search “Top TVs of 2026” in the search bar at CyberGuy.com.
Also, think about privacy before you start. Open only the album you want people to see. No one needs your screenshots, receipts or random camera roll surprises popping up on a 65-inch TV.

How to share iPhone photos on a TV with AirPlay
AirPlay is usually the cleanest option for iPhone owners. It works with Apple TV, many smart TVs, some Roku devices, and select Fire TV smart TVs that support AirPlay.
Here’s how to do it:
- Open the Photos app on your iPhone.
- Tap the photo or video you want to show.
- Tap the Share button.
- Swipe up if needed.
- Tap AirPlay.
- Then choose your Apple TV or AirPlay-compatible TV.
- If a passcode appears on the TV, enter it on your iPhone.
This is great when you are at home, and your TV already supports AirPlay. It can also work at someone else’s house, but both devices usually need to be on the same Wi-Fi network. If you use AirPlay often, it is also worth reading CyberGuy’s report on how hackers are breaking into Apple devices through AirPlay so you know how to use it more safely.
How to mirror your iPhone screen
Sometimes the AirPlay button does not appear where you expect it. In that case, mirror your whole iPhone screen.
- Swipe down from the top-right corner to open Control Center.
- Tap the Screen Mirroring button , which looks like two overlapping rectangles.
- Select the Apple TV or a compatible smart TV.
- Then open Photos and start swiping.
- The catch is that everyone can see what is on your screen.
Turn on Do Not Disturb or Focus first so private texts and alerts do not show up during the slideshow.
How to share Android photos on a TV with Chromecast
For Android owners, Google Photos and Chromecast are a strong combo. This works with Chromecast devices, Google TV Streamer and many TVs with Google Cast built in.
Settings may vary depending on your Android’s manufacturer
- Open Google Photos.
- Select the photo or album you want to show.
- Tap More , then tap Cast.
- Choose your Chromecast or compatible TV.
- Once it connects, open a photo or video and swipe through your vacation shots.
This method also works from Google Photos on iPhone or iPad if you are signed into your Google Account.
How to share Samsung Galaxy photos with Smart View
Samsung Galaxy phones have a built-in screen mirroring feature called Smart View. It is one of the easiest ways to show photos on a Samsung TV and some other compatible displays.
Settings may vary depending on your Android’s manufacturer
- Swipe down from the top of the screen to open Quick Settings.
- Tap Smart View . The icon usually looks like a play button or phone-style shape sending to a screen.
- Choose your TV.
- Tap Start now if prompted.
- Then open your Gallery or Google Photos app.
Smart View mirrors your whole phone screen, so the same privacy rule applies. Open the album first and silence notifications before you start.
How to use Samsung DeX for a cleaner big-screen setup
Some Samsung Galaxy phones and tablets support Samsung DeX. This can make your phone feel more like a desktop on a TV or monitor.
You can connect with a USB-C to HDMI cable or adapter. Some TVs also support wireless DeX through compatible screen mirroring. Once connected, open your photo app and display your album from the big screen.
DeX can be especially useful when you want a cleaner setup for a family gathering, reunion or backyard slideshow because you are not simply throwing your entire phone screen onto the TV.
How to connect your phone with an HDMI cable
A cable may feel old school, but it is often the most reliable method. It also avoids Wi-Fi problems at someone else’s house.
For iPhone 15 and newer USB-C models, use a USB-C to HDMI adapter or cable. Plug it into your iPhone, connect the HDMI cable to the TV or projector and switch the TV to the correct HDMI input.
For older iPhones with Lightning, use a Lightning Digital AV Adapter and an HDMI cable.
For Android phones, USB-C to HDMI support depends on the model. Many Samsung Galaxy phones support video output, while some other Android phones may not. If your phone supports it, plug the USB-C to HDMI adapter into your phone, connect the HDMI cable to the screen and choose the correct input.
This is one of the best options for outdoor projectors because it avoids weak backyard Wi-Fi.

How to show photos from a laptop
A laptop gives you more control when you want a polished slideshow. You can open iCloud Photos, Google Photos, OneDrive or a folder of downloaded photos. Then connect the laptop to a TV or projector with HDMI.
On Windows , press Windows key + P to choose how the screen appears.
On a Mac, connect the display and use System Settings if you need to adjust the screen arrangement.
You can also cast from some laptops to wireless displays. On Windows, press Windows key + K and select a compatible wireless display. This can work well with Miracast-enabled TVs and adapters.
The laptop method is helpful when multiple people have sent you photos after the trip, and you want everything in one place before guests arrive.
How to use a tablet as the shared screen
A tablet works well for smaller groups. It is bigger than a phone, easier to pass around and less awkward at a dinner table.
On iPad, open Photos, Google Photos or iCloud Photos . You can also AirPlay to a bigger screen if one is nearby.
On an Android tablet , open Google Photo s or your gallery app and cast to a Chromecast-enabled TV when available.
This is a good fallback when you are at someone else’s house, and you do not want to mess with their TV settings.
How to share photos on Roku
Roku gives you several options depending on your phone.
If you have an iPhone and the Roku device supports AirPlay, use AirPlay or Screen Mirroring from Control Center.
If you have Android or Windows, Roku supports screen mirroring from compatible devices. Roku also has Photo Streams in the Roku mobile app, which lets you upload photos and share a stream.
Photo Streams can be a nice option for parties because you can prepare the photos before people arrive instead of connecting your phone in the moment.
How to share photos on Fire TV
Some Fire TV smart TVs support AirPlay. If yours does, you can enable AirPlay in the Fire TV settings and share from an iPhone.
Fire TV also supports display mirroring on certain models. Go to Settings , then Display & Sounds , then Enable Display Mirroring. After that, connect from your compatible phone, tablet or computer.
Not every Fire TV device supports every mirroring option, so this is one place where the exact model can make a difference.
How a streaming device can help
A streaming device can make photo sharing easier if your older TV lacks AirPlay, Chromecast or screen mirroring. Roku, Fire TV, Apple TV and Chromecast-style devices can give an older screen newer sharing features.
If you are thinking about adding one, CyberGuy’s guide to the 5 best streaming devices in 2026 at cyberguy.com breaks down strong options for different homes and budgets.
This can also help if you visit relatives who have a perfectly good TV that feels stuck in another decade. Plug in the streaming device, connect it to Wi-Fi and you may have a much easier way to show photos.
A smart TV or streaming device can help bring your photo album to the biggest screen in the room. (Kurt “CyberGuy” Knutsson)
How to make a shared album before guests arrive
A shared album can save you from digging through your camera roll while everyone waits.
On iPhone, use iCloud Shared Albums if your guests are also in the Apple world. Select the photos , tap Share, choose Add to Shared Album and post them to the album.
Google Photos is more flexible for mixed groups. You can create a shared album, add photos and send a link. That works well when some people have iPhones and others have Android phones.
This is also the easiest way to let other people add their own vacation shots. After a group trip, ask everyone to upload their best photos to one shared album before the slideshow.
For more family-friendly options, CyberGuy has also rounded up the best free sites for sharing photos and videos with your extended family.
How to show vacation photos outdoors
Outdoor photo sharing needs a little more planning. Sunlight, Wi-Fi and power can all get in the way.
A portable projector is the most fun option for backyard photo nights. Use a white wall, projector screen or even a clean white sheet pulled tight. For the best picture, wait until dusk or evening.
You can connect your phone with HDMI, cast wirelessly if the projector supports it or plug in a streaming stick such as Roku, Fire TV, Chromecast or Google TV Streamer. If your projector has Google TV built in, you may be able to open Google Photos or cast directly.
For outdoor setups, bring a long extension cord, portable speaker, HDMI cable, phone adapter and backup charger. Wireless casting can work, but a cable is less likely to fail when the Wi-Fi signal is weak.
Best methods by situation
If you are at your own house, use AirPlay, Chromecast, Smart View or a shared album on your smart TV.
If you are at someone else’s house, use an HDMI cable or shared album link. That avoids asking for Wi-Fi passwords and digging through their TV menus.
If you are outside, use a projector with HDMI or a streaming stick. Keep a charger nearby because photo and video sharing can drain your phone quickly.
If you have a mixed iPhone and Android crowd, use Google Photos or a shared album link. It is usually easier than trying to make every device talk to the same TV.
If you want the least awkward option, prepare an album before people arrive. Your future self will thank you.
Privacy tips before you start sharing
Before you turn your vacation memories into a living room or backyard slideshow, take a minute to make sure you are only sharing what you actually want everyone to see.
1) Make a clean album first
Create a dedicated album with only the photos you want people to see. Hide or remove anything personal before you cast or mirror. Before you put anything on a big screen, you may also want to hide private photos on your iPhone or Android from snoops.
2) Silence alerts before you cast
Turn on Do Not Disturb or Focus so messages and notifications stay off the big screen. Avoid opening your full camera roll in front of guests. Start from the album instead. If your camera roll is overflowing with screenshots, duplicates and random saves, CyberGuy’s five digital clean-up tips you didn’t know you needed can help you tidy things up before slideshow night.
3) Watch what your photos reveal
Be careful with location data if you share an album link. Some photo services may include or display location details depending on your settings. Also, remember to stop casting or mirroring when you are done. It sounds obvious until your phone reconnects to the TV while you are checking something private. And while you are using a smart TV, take a minute to review the privacy clauses hidden in smart home devices that may affect what your TV, speaker or connected gadgets collect.
Kurt’s key takeaways
Vacation photos are more fun when everyone can actually see them. Passing one phone around the room kills the moment, especially when you have videos, Live Photos and group shots worth showing. The best method depends on where you are. At home, AirPlay, Chromecast or Smart View may be easiest. At someone else’s house, an HDMI adapter can save you from Wi-Fi headaches. Outdoors, a projector can turn a backyard into a photo night people actually remember. But let’s be real here. The smartest move is making a clean album before anyone arrives. That way, you control what shows up, you avoid awkward screen surprises and you spend less time fumbling with settings.
What is your favorite way to show vacation photos when family or friends come over: phone, TV, projector or something else? Let us know by writing to us at CyberGuy.com.

Google is open-sourcing its 3D emoji
Now, if you want to, you can use Google’s 3D emoji in your own creations. The company shared some details about how it went about designing the little pictograms and why, as part of World Emoji Day on Friday. Things you might not necessarily worry about in a 2D illustration suddenly become very important when you’re talking about a 3D model. Is a smiley face a sphere? A mask? A flat disc?
In addition to offering a behind-the-scenes look at Google’s design process, it also announced that it would be completely open-sourcing the emoji set:
We’re handing over raw .OBJ files to the community so they can use them to build immersive VR worlds, indie apps or weird memes.
Exactly what kind of “immersive VR worlds” someone might want to build with a bunch of emojis is a bit of a mystery to me. But if the Emoji Movie is any indication, it won’t be good. Google’s Noto Emoji 3D made their debut in May and were met with 😬 reactions.
