Sit still, Veebot is trying to draw your blood

A new prototype for a medical robot has the same accuracy rate as human nurses for drawing blood. And no, we're not talking about the Terminator killer robots - the Veebot uses infrared light, ultrasound, and imaging software to read your veins.

Getting your blood drawn is never a fun experience, and some people are better about it than others. There are the ones who can sit still and not make a peep, and those who hyperventilate, cry, faint at the sight of blood. Then there are those who have real medical conditions, like requiring butterfly needles for smaller veins or gentler pressure to avoid bruising.

A Mountain View, CA-based startup is trying to make that process more at ease. With the Veebot, this medical robot technician can scan the patient’s arm using an image-analysis software to select the vein that’s ideal for drawing blood. The patient would first insert his or her arm through a padded archway where an inflatable cuff pumps the arm to restrict blood flow. Then, Veebot will use ultrasound and infrared light to examine the best vein before aligning the needle and inserting it through. There’s even a grip for the patient to hold to help pump blood (or squeeze for nervousness). The team estimates that Veebot only takes one minute to process all this information – the only thing the human nurse has to do is attach the blood test tube and, of course, supervise the patient in case they pass out.

At the moment, Veebot has an 83 percent accuracy at selecting the best vein, which is more than some of us can say about nurses who poke and prod multiple times before they find a useable spot. The team is currently working on upping that rate to 90 percent accuracy before starting clinical trials. Veebot’s Richard Harris, a third-year undergraduate in Princeton University’s mechanical engineering program, tells IEEE Spectrum that the idea started because it combined his love for both robotics and computer vision. “It had demanding requirements because you’d be fully automating something that is different every time and deals with humans,” he explained. Such complexities did not come without obstacles; the original prototypes for Veebot date all the way back to 2009.

Now that a successful version is nearly ready, Harris is gearing up to sell to large medical facilities with an estimated market of $9 million. But before you shy away thinking this robot will probably try to kill you while you’re not looking, look at it this way: Surgical robots have existed for years and are pretty common in most hospitals these days. A blood test is much less complex than surgery, so the process can’t be that bad… right? Besides, if you don’t like Veebot, there are plenty of other robots that can help you draw some blood – and it ain’t gonna be pretty.

AI companies spend enormous amounts of time convincing us their technology is safe and secure. But what happens when those same companies become targets of increasingly sophisticated AI-powered attacks? Anthropic, the company behind Claude, is now facing that question. According to a Washington Post report, cybersecurity startup Cathedral discovered vulnerabilities that let its researchers access sensitive information in Anthropic's internal systems.

The researchers used AI agents to identify potential entry points in less than 12 hours. Interestingly, they didn't need to crack Claude itself. Instead, they exploited weaknesses in third-party business applications that Anthropic uses for everyday operations. Anthropic's security testing program disclosed the findings, which allows outside researchers to identify and report vulnerabilities.

Military working dogs charge into places the rest of us would flee. So, I understand why anyone would want to breed tougher, healthier dogs for the job.

AI can describe a picture, identify objects, and answer questions about what a camera sees. But when a blind user needs a quick answer, getting an entire spoken essay about the scene isn't exactly helpful. Researchers at the University of Maryland (UMD) have found that AI-powered visual assistance can leave blind users doing too much work to get the information they actually need.

The study, titled Say It My Way: Exploring Control in Conversational Visual Question Answering with Blind Users, examined how people interact with Be My AI, an AI-powered feature of the Be My Eyes app. The researchers found that users often received lengthy descriptions that didn't adequately address their immediate goals, forcing them to ask follow-up questions or find ways to steer the AI towards a more useful answer.
