JackRabbot 2 is Stanford’s friendly new campus-roaming social robot

Add as a preferred source on Google

Boasting a human-friendly appearance, with a two-fingered arm, squat body, and large cartoonish eyes, you could be forgiven for thinking that JackRabbot 2 is a character from some as-yet-unannounced sequel to Pixar’s WALL-E. In fact, it’s a real robot created by researchers at Stanford University — which was first shown off at an on-campus event this week.

The goal of the JackRabbot 2 project (known as “JR2” by its creators) is to build a robot that’s not just capable of navigating around the sprawling Stanford campus, but to build one that is also able to do so while surrounded by people. After all, if the future is going to see us live and work among robots (or vice versa), it’s important to figure out the rules of social engagement as soon as possible.

“JR2 focuses on being in human environments with humans,” Professor Silvio Savarese, associate professor of computer science, who leads the JackRabbot project, and Roberto Martín-Martín, postdoctoral scholar of Computer Science, told Digital Trends. “Previous technologies have focused on moving a robot from A to B. We focus on moving JR2 from A to B in a way that obeys human social conventions and etiquette. The robot respects personal space, groups of humans talking, and pays extra attention — even reducing the velocity if needed — when it is necessary to pass close to a person.”

As its name implies, JR2 is the second robot in the JackRabbot series. This one adds considerably more hardware to the mix, however — including two state-of-the-art GPUs, better sensors with 360-degree lidar, depth cameras on its head, microphones, and an arm. “JR2 can convey intentions to humans using its arm,” the researchers said. “But it can also interact with the environment, open doors and drawers, grab us a coffee, and bring it to us.”

It is also designed with more human interactivity in mind: for instance, communicating via arm gestures, smiling or frowning, and using lights, sounds, and a simplified voice.

In short, it sounds like the robot butler of our dreams, although the team notes that it is not quite consumer-ready yet. On a scale of 1 to 10, from fundamental research to consumer product, they rate JR2 as a 7.

“For example, in terms of mobility and social navigation, we are a bit higher, probably at 8,” they said. “When it comes to interacting physically with the environment with the arm we are a bit behind, probably at a 6. Interaction is difficult. We are working on these last two to three points to make mobile robots to be ready to deliver your products, guide you in airports, or assist you at home.”

Anker just exposed a big problem with portable power stations
Appliance, Device, Electrical Device

When you're shopping for a portable power station, there's one number that's almost impossible to ignore: battery capacity. A 2 kWh battery should give you roughly 2 kWh of usable power, right? Unfortunately, things aren't quite that simple. Anker SOLIX has published new efficiency data for its S Series portable power stations, and it's putting the spotlight on something that doesn't get nearly as much attention as capacity: how much of the energy stored inside the battery actually makes it to your devices.

According to Anker, portable power stations are commonly advertised with efficiency figures measured under relatively heavy loads, where they can reach roughly 89% to 92% efficiency. But that's not necessarily how most people use one during an outage. Think about what you'd actually plug in. A Wi-Fi router might sip power continuously, a refrigerator switches its compressor on and off throughout the day, and a CPAP machine could run overnight. Together, those devices may draw just a fraction of what a large power station is capable of supplying. And that's where efficiency can start slipping.

OpenAI’s first gadget sounds like a tiny expressive AI companion
The device will have a doughnut-shaped body, built-in cameras, and moving parts

For months, reports have suggested that OpenAI’s first hardware product would be a screen-free smart speaker designed to act more like an AI companion. We already knew it could understand its surroundings, be carried around the home, and proactively help users. A new Bloomberg report now gives us a clearer picture of what the device may actually look like.

As per the report, OpenAI’s first gadget will be shaped like a doughnut and measure about the same size as a hockey puck. You will be able to carry it between rooms or leave it nearby on whatever surface is convenient. The device is expected to be on the expensive side, as the company has pondered pricing it around $300 to $400. A release is currently planned for 2027.

Google Antigravity just built an AI translator that works without the internet
Electrical Device, Switch, Robot

Google has shown off a new AI project that could make language barriers a little less intimidating, and it doesn't need an internet connection to do it. The company has introduced the Gemma Translator, a compact prototype built in collaboration with Antigravity. Unlike most AI translation tools that rely on cloud processing, this device runs entirely offline using Gemma 4 E2B, Google's lightweight open model. Everything happens locally on the device, making it both portable and independent of an internet connection. The prototype is powered by a Raspberry Pi 5 and includes a microphone and speaker inside a custom 3D-printed enclosure, creating a self-contained translator you can carry almost anywhere.
