The coolest technology from Day 2 of CES 2026

LAS VEGAS — Crowds filled the newly opened showrooms on the second day of CES and were greeted by thousands of robots, artificial companions, assistants, longevity technology, wearables and more.

Siemens President and CEO Roland Busch started the day with a keynote address detailing how his clients are using artificial intelligence to transform their businesses. He was joined on stage by Nvidia CEO Jensen Huang to announce the expanded partnership, saying they are launching a new industrial revolution powered by artificial intelligence to reinvent every aspect of manufacturing, production and supply chain management.

Lenovo ended the day with a visual banquet featuring guest stars highlighting how its AI platforms can help people personally (wearables), their businesses (enterprise platforms) and the world around them. To emphasize its point, its CEO Yang Yuanqing was joined by tech superstars such as Nvidia's Huang, AMD CEO Lisa Su and Intel CEO Lip-Bu Tan.

CES is a huge opportunity every year for companies large and small to showcase the products they plan to put on shelves that year. Here are the highlights from day two:

Gaming technology company Razer is well known for introducing noteworthy hardware at CES, such as haptic or haptic seat cushions and triple-screen laptops.

This year, the company is moving beyond its standard gaming base and showcasing two AI-powered prototypes—a gaming headset with headphones that doubles as an all-in-one assistant, and an AI-powered desktop assistant that can provide gaming tips as well as organize the user's life.

The holographic companion, based on the Razor on-screen AI assistant launched last year (Project Ava), has moved beyond the screen into a small glass tube that sits next to your computer. The animated sprite has built-in speakers and a camera so it can see the world around it.

Both devices are AI-agnostic, so you can use your preferred model. For the demonstration, the headset – Project Motoko – ran on OpenAI's ChatGPT. The Ava project was developed by Grok from xAI. Although still in development, Razer said it expects both devices to be commercially released later this year.

Imagine your plane is landing and when you look out the window, you see autonomous robots guiding it to the gate and then unloading your luggage. Oshkosh Corporation offers this future for airports large and small.

At CES, the company unveiled a fleet of autonomous airport robots designed to help airlines perform what it calls the “perfect turn”—the precisely timed process that occurs after a plane lands, including refueling, cleaning, cargo handling, and getting passengers off and on.

The goal for travelers is to reduce delays without compromising safety, CEO John Pfeiffer said. The technology is also designed to perform these tasks on asphalt, even in harsh weather conditions such as winter storms or extreme heat, where conditions are taxing for human crews, Pfeiffer said. Testing with major airlines is already underway, and the robots will likely debut at major hubs such as Atlanta or Dallas, with the goal of being deployed over the next few years.

Chinese robotics manufacturer Roborock has unveiled a vacuum cleaner that literally sprouts chicken legs, allowing you to navigate stairs and clean the steps along the way.

The newly revealed Saros Rover was a little slow going up and down (but it cleared every step) during demo, but Roborock says it will be able to climb almost any stairs, including spiral ones. There is no release date for the Rover, but the company says it is still in development.

While it may look like a regular scale you'd buy for your bathroom, the new Body Scan 2 from Withings measures much more than just weight. After taking off their shoes and socks, people lined up to try out the smart scale, which measures 60 different biomarkers in 90 seconds, including heart age, vascular age and metabolism, using the balls of their feet and hands.

The $600 scale, available in the spring, also assesses nerve health and measures changes in a person's electrodermal activity, or electrical properties of the skin, due to sweat gland activity. The smart scale and accompanying app, which cost $10 a month or $100 a year, provide users with personalized advice and information about their health trajectory. The French company's goals are to help people take charge of their health and break bad habits to promote longevity.

Commonwealth Fusion Systems, NVIDIA and Siemens announced Tuesday that they are working together to use artificial intelligence to accelerate the development of nuclear fusion into a new source of carbon-free energy.

In Massachusetts, Commonwealth Fusion Systems is building a prototype fusion power plant called SPARC, which is about 70% complete. The new partnership will create a “digital twin,” or online simulation, of a physical machine.

CFS CEO Bob Mumgaard said the company will ask simulation questions to accelerate progress on the physical machine and quickly analyze data, compressing years of manual experimentation into weeks of insight.

SPARC is a prototype of the company's first planned power plant, called ARC, which is scheduled to come online in the early 2030s. The device will use very strong magnets to create the conditions for nuclear fusion. Mumgaard also reported that the first CFS high-temperature superconducting magnet was installed at SPARC.
