A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

Here's how Houston ranks among the best U.S. cities to start a career

New Horizons

College graduates staying in Houston are in the right place to be, according to a new WalletHub study. Houston has emerged on a new list of the 100 best places in America for starting a career.

Houston ranked 51st out of 182 U.S. cities based on its quality of life and vast opportunities for new college graduates transitioning into the workforce. The study compared each city based on 25 relevant metrics, like the availability of entry-level jobs, each city's annual job growth rate, workforce diversity, median annual income, housing affordability, and others.

Atlanta, Orlando, and Austin respectively comprised the top three best places to start a career.

Houston ranked 48th overall for its quality of life, and appeared No. 51 for its professional opportunities for new college graduates. Whether its starting a new business or entering a high-earning job field, Houston has many more opportunities than the vast majority of other cities on the list.

"The best cities for starting a career not only have a lot of job opportunities but also provide substantial income growth potential and satisfying work conditions," said WalletHub analyst Chip Lupo. "It’s also important to consider factors such as how fun a city is to live in or how good of a place it is for raising a family, to ensure life satisfaction outside of your career."

Other Texas hotspots for early career professionals
Austin boasts the best quality of life out of all 182 cities in the report, and the 10th best professional opportunities. The state capital also outperformed all other U.S. cities with the highest monthly average starting salaries for early career workers after being adjusted for the city's cost of living. Austin also offers the 15th highest number of entry level jobs per capita, the report said.

In a separate comparison of the cities with the largest share of residents aged 25 to 34, Austin ranked No. 5 nationally.

"In addition, Austin’s median annual household income is the 10th-highest in the nation, providing strong earning potential for those starting a career or a business," the report said. "Austin is also the sixth best city for singles, offering a vibrant social scene alongside strong career opportunities for young professionals."

Elsewhere in Texas, Dallas ranked as the second-best city in Texas for new grads to start a career and 12th nationally. Additional cities that made it into the top 100 best U.S. cities for early career professionals include Plano (No. 32), Irving (No. 42), Fort Worth (No. 64), Amarillo (No. 73), and San Antonio (No. 85).

The top 10 best cities for starting a career are:

  • No. 1 – Atlanta, Georgia
  • No. 2 – Orlando, Florida
  • No. 3 – Austin, Texas
  • No. 4 – Tampa, Florida
  • No. 5 – Miami, Florida
  • No. 6 – Charleston, South Carolina
  • No. 7 – Pittsburgh
  • No. 8 – Knoxville, Tennessee
  • No. 9 – Salt Lake City, Utah
  • No. 10 – Columbia, South Carolina

Persona AI teams with Under Armour to protect next-gen robots

Future Fabrics

Houston-based Persona AI has cemented a partnership with sportswear manufacturer Under Armour to provide materials to protect future robots operating in dangerous conditions.

Through the partnership, Persona AI and Under Armour will launch a research initiative to explore whether advanced performance textiles can improve the durability and resilience of humanoid robots operating in harsh industrial environments.

“This is an opportunity to apply our innovation expertise in a new context,” Kyle Blakely, senior vice president of innovation, design studio, development, and testing at Under Armour, said in a news release. “Robotics presents a fascinating new design challenge, and we aim to play a leading role in shaping performance solutions for these environments. As humanoid systems take on more physically demanding roles, we see real potential to create new market opportunities, and we’re exploring how concepts like thermal management, abrasion resistance, and flexibility translate beyond sport."

Founded in June 2024 by former NASA engineer Nicolaus Radford and former Figure AI CTO Jerry Pratt, Persona AI has quickly risen to be a top name in the development of humanoid robotic systems. Radford previously was the principal investigator at NASA’s Dexterous Robotics Lab before becoming CEO of Nauticus Robotics. While at NASA, he was the chief engineer behind Robotnaut 2, the first humanoid robot on the International Space Station.

Persona AI raised $25 million in preseed funding to develop humanoid robots designed to operate in shipyards and other industrial sites. The company has inked partnerships with HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Robotic, and Korean manufacturing firm Vazil Company to create and deploy humanoid robots for complex welding tasks in shipyards.

These environments often involve exposure to dangerous chemicals, harsh weather and other potential hazards. The partnership between Persona AI and Under Armour will combine the clothing manufacturer’s development of resilient but flexible materials with the humanoid design of Persona AI.

Though best known for its sportswear, Under Armour produces a wide range of specialist fabrics and clothing, including an entire line used by the U.S. military. The company’s track record of developing high-performance fabrics built to withstand war zones and desert conditions makes it a strong partner in Persona AI’s latest endeavor.

“We chose to work with Under Armour because of their track record of innovation with these types of performance materials,” Radford said. “As we develop humanoids for intense and potentially hazardous environments, this collaboration helps us understand how advanced materials can enhance long-term reliability, thereby informing solutions to better protect workers in the field.”

Waymo suspends robotaxi service in Houston due to weather concerns

Transportation news

Waymo has suspended driverless car services in Houston and other major Texas cities, and in Atlanta, after one of its vehicles was stranded by flooding during heavy rains that will likely also hinder travel in a large swath of the U.S over the holiday weekend.

Severe thunderstorms with large hail and gusty winds were possible Friday, May 22 in Texas and other parts of the Southern and Central Plains, the National Weather Service said.

Forecasters warned of possible flash flooding along the Gulf Coast of Texas and Louisiana on Saturday, when rain and thunderstorms were expected across much of the central and eastern U.S.

The Waymo vehicle got stuck during a downpour in Atlanta on Wednesday that flooded streets and even part of a downtown highway. The vehicle was not occupied and was later recovered, the company said in a statement. At least one other Waymo vehicle was waylaid during the storm.

Waymo serves only the city of Atlanta in Georgia, and services Dallas, Houston, Austin, and San Antonio in Texas.

The company paused service in Texas “out of an abundance of caution for the forecasted severe weather,” the statement said.
