Houston- and Boston-based Square Robot Inc.'s newest tank inspection robot is commercially available and certified to operate at extreme temperatures.

The new robot, known as the SR-3HT, can operate from 14°F to 131°F, representing a broader temperature range than previous models in the company's portfolio. According to the company, its previous temperature range reached 32°F to 104°F.

The new robot has received the NEC/CEC Class I Division 2 (C1D2) certification from FM Approvals, allowing it to operate safely in hazardous locations and to perform on-stream inspections of aboveground storage tanks containing products stored at elevated temperatures.

“Our engineering team developed the SR-3HT in response to significant client demand in both the U.S. and international markets. We frequently encounter higher temperatures due to both elevated process temperatures and high ambient temperatures, especially in the hotter regions of the world, such as the Middle East," David Lamont, CEO of Square Robot, said in a news release. "The SR-3HT employs both active and passive cooling technology, greatly expanding our operating envelope. A great job done (again) by our engineers delivering world-leading technology in record time.”

The company's SR-3 submersible robot and Side Launcher received certifications earlier this year. They became commercially available in 2023, after completing initial milestone testing in partnership with ExxonMobil, according to Square Robot.

The company closed a $13 million series B round in December, which it said it would put toward international expansion in Europe and the Middle East.

Square Robot launched its Houston office in 2019. Its autonomous, submersible robots are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments.

Texas tops ranking of best states for investors in new report

by the numbers

Texas ranks third on a new list of the best states for investors and startups.

Investment platform BrokerChooser weighed five factors to come up with its ranking:

  • 2024 Google search volume for terms related to investing
  • Number of investors
  • Number of businesses receiving investments in 2024
  • Total amount of capital invested in businesses in 2024
  • Percentage change in amount of investment from 2019 to 2024

Based on those figures, provided mostly by Crunchbase, Texas sits at No. 3 on the list, behind No. 1 California and No. 2 New York.

Especially noteworthy for Texas is its investment total for 2024: more than $164.5 billion. From 2019 to 2024, the state saw a 440 percent jump in business investments, according to BrokerChooser. The same percentages are 204 percent for California and 396 percent for New York.

“There is definitely development and diversification in the American investment landscape, with impressive growth in areas that used to fly under the radar,” says Adam Nasli, head analyst at BrokerChooser.

According to Crunchbase, funding for Texas startups is off to a strong start in 2025. In the first three months of this year, venture capital investors poured nearly $2.9 billion into Lone Star State companies, Crunchbase data shows. Crunchbase attributes that healthy dollar amount to “enthusiasm around cybersecurity, defense tech, robotics, and de-extincting mammoths.”

During the first quarter of this year, roughly two-thirds of VC funding in Texas went to just five companies, says Crunchbase. Those companies are Austin-based Apptronik, Austin-based Colossal Biosciences, Dallas-based Island, Austin-based NinjaOne, and Austin-based Saronic.

Houston humanoid robotics startup secures millions in pre-seed funding

my robot

A Houston-based startup developing AI-powered humanoid robots for manufacturers and other businesses has raised more than $10 million in pre-seed funding less than a year after its founding.

Nic Radford, co-founder and CEO of Persona AI, declines to disclose the amount raised. However, he tells InnovationMap that it was an eight-figure total.

While not providing names, Radford says Persona AI’s first outside investors include VC firms, institutions and high-net-worth individuals in the U.S., London and Singapore. One of the high-net-worth investors was among the first employees at SpaceX, Elon Musk’s Brownsville, Texas-based aerospace company, according to Radford.

No Houston investors have participated in the funding round yet. However, Radford says he’s working on bringing aboard one local investor before the round closes.

“Houston’s the perfect city to do a company like this in,” Radford says. “It’s just not the perfect investor climate, but it's the perfect city from a customer aspect.”

Persona AI’s pre-seed funding comes amid a dramatic surge in investment capital chasing AI startups. Global funding for AI-related companies exceeded $100 billion in 2024, up more than 80 percent from the 2023 total, Crunchbase data shows.

Radford and co-founder Jerry Pratt, the startup’s chief technology officer, bootstrapped Persona AI. The third co-founder, Jide Akinyode, serves as Persona AI’s chief operating officer. Radford and Akinyode helped develop NASA’s six-foot-two-inch Valkyrie humanoid robot and both are former employees of Webster-based Nauticus Robotics, a provider of autonomous subsea robots.

Persona AI launched last June in what Radford calls “anti-stealth mode.” The startup is close to announcing its first customer, which does business in the industrial sector. Persona AI expects customers to take delivery of its first robot in 18 to 24 months, Radford says.

Persona AI will operate primarily as a robotics-as-a-service provider, with the company retaining ownership of the lifelike robots and selling the labor that they supply. Radford says the startup’s robots will help alleviate a shortage of skilled labor in sectors like manufacturing.

A report released last year by consulting firm Deloitte and the Manufacturing Institute declared that as many as 1.9 million manufacturing jobs in the U.S. could go unfilled between 2024 and 2033 due to a skills gap and a tight labor market.

Persona AI competes in a market with enormous potential. In November, analysts at Citi Global Insights projected that the global market for humanoid robots could soar to $7 trillion by 2050, with 650 million of the robots tackling all sorts of jobs.

Radford says Personal AI is developing a “rugged” five-foot-eight-inch humanoid robot that’s able to survive tough indoor and outdoor conditions and take on tasks like carting around sheet metal, tending to metal-stamping machines, moving storage bins and handling order fulfillment. He likens his company’s robot prototype to a Ford F-150 pickup truck, compared to the less-sturdy versions produced by robotics competitors, which he calls the Toyota Camry or Volkswagen Beetles of the field.

Radford says he and his team “are building a really compelling startup in one of the hottest markets and one of the greatest cities.” Employees work at Persona AI’s headquarters in Houston or its satellite office in Pensacola, Florida, where Pratt is located.

“We don’t hire anybody that’s not a rock star or superstar,” says Radford, “and I think the city is going to benefit tremendously from our efforts at Persona.”

Radford saw his last company, Nauticus Robotics, from founding to IPO, left the company in January and previously told InnovationMap that he couldn't get the idea of advancing humanoid robotics out of his head. Read more here.

Houston hospital named among smartest in the nation

hi, tech

Houston hospitals are chock-full of smart people. But they’re also equipped with lots of “smart” technology. In fact, five local hospitals appear on Newsweek’s new list of the world’s best “smart” hospitals.

To compile the list, Newsweek teamed up with data provider Statista to rank the world’s top 330 hospitals for the use of smart technology. The ranking factors were electronic functionality, telemedicine, digital imaging, artificial intelligence (AI), and robotics.

The highest-ranked Houston hospital is the University of Texas MD Anderson Cancer Center, appearing at No. 6. The hospital was recognized for advancements in electronic functionality, AI and robotics.

“MD Anderson has a significant opportunity and a responsibility to our many stakeholders to create a digital ecosystem that promotes collaboration and advances scientific discovery to enhance patient outcomes,” David Jaffray, the cancer center’s chief technology and digital officer, said in a 2021 news release.

“Through our ongoing focus on enabling the use of new technologies to place quantitative data in context for our researchers,” Jaffray added, “we foster cutting-edge oncology data science to inform our cancer discovery research and to accelerate translation of our research findings into benefits for cancer patients.”

Ahead of MD Anderson on the list are:

  1. Mayo Clinic in Rochester, Minnesota.
  2. Cleveland Clinic in Cleveland.
  3. Massachusetts General Hospital in Boston.
  4. Johns Hopkins Hospital in Baltimore.
  5. Mount Sinai Hospital in New York City.

Other Houston hospitals on the list are:

  • Houston Methodist Hospital, No. 11.
  • Baylor St. Luke’s Medical Center, No. 105.
  • Texas Children’s Hospital, No. 197.
  • Memorial Hermann-Texas Medical Center, No. 266.

Texas robotics company expands in Houston with service-focused automation technology

order's up

Snazzy sombrero-wearing robots are gliding over to your table, carrying chips, salsa, and drinks, electronic eyes wide open on its interactive screen, ready to serve. The bot, provided by the new Houston franchise branch of RobotLAB Inc., debuted at Johnny Tamales Tex-Mex Cantina in Missouri City last week.

The restaurant's owner, Anil Patel, arranged for a one-month trial rental of the machine. But so far, he tells InnovationMap that he’s pleased with his “no-brainer” decision to add a small food delivery robot, which he says has huge marketing potential.

“I’m a sucker for technology. You look at it, and I think this is the future,” says Patel, who used to work in the health care industry.

That vision is shared by Elad Inbar, founder and CEO of Dallas-based RobotLAB, who in July expanded his company’s Texas franchise operations with the opening of a Houston branch.

“For many years, robots were toys — for geeks. You had to build them yourself, program them yourself,” Inbar says.

But the electronics revolution that brought handheld phones to the mainstream inspired Inbar to turn that concept to robotics when he formed RobotLAB in 2007.

“To me, this was completely a wake up call — seeing the market shift, and you know, bringing the opportunity to the mass market,” he says.

The company started by providing small robots to schools, and the company now works with two-thirds of the school districts in the country, Inbar says, touting that it is the "largest, most experienced" robotics company.

Keith Edwards, who owns RobotLAB’s Houston franchise with his brother Daniel, said his office aims to provide 50 robots in its first year of operation. While the use of robots has become more common globally, especially in Asian hotels and restaurants, for American business owners, robots are definitely not a standard decision, Edwards says.

The challenge lies in educating them about how robotics provides a solution for staffing shortages, Edwards says. With the touch of a button, the robot used in Patel’s restaurant can be programmed to sing happy birthday and deliver a dessert, or return dirty dishes back to the kitchen sink.

Through its franchisees, RobotLAB has already set up robots inside numerous restaurants, including eight food delivery models at four Houston locations of revolving sushi bar Kura Sushi.

Wings Over Frisco in the Dallas metro area and entertainment complex AREA 254 in Killeen also use RobotLAB food delivery robots. In August, the Tulsa International Airport introduced, on a trial basis, “Cloi,” another bot from RobotLAB, that guides visitors and has a selfie feature.

RobotLAB provides some 50 types of robots, Inbar says, ranging in function from cleaning, warehouse stacking, to food delivery, with plans and potential for more.

The company also has a presence in the senior living space, with a humanoid life-sized interactive robot named Pepper, that works with residents who suffer from dementia. While no Houston senior communities have yet come on board, Inbar says the company works with assisted living communities in Dallas, Wisconsin, New Jersey and Virginia.

RobotLAB does not manufacture the robots, but provides the models, which can be purchased or leased. The company partners with manufacturers all over the world to provide the robots.

The cost to purchase a robot outright ranges widely, anywhere from $3,400 for an autonomous vacuum cleaner to $32,000 for a life-sized model, according to the website.

It provides one-on-one service for all aspects of implementation and any repair.

The proof of concept and related costs for the trial run for the Johnny Tamales robot was $2,990, Edwards says, which would apply toward a possible purchase of the $9,500 robot.

The daily labor cost, according to Inbar, for a food delivery robot amounts to about $15 to $17 a day, and for cleaning robots, about $27 a day.

The delivery robots run on a battery charge which lasts which lasts from nine to 13 hours, depending on the model. A cleaning robot does not last as long, but can clean 20,000 square feet on a single charge, Inbar says, and discharge dirty water, charge itself and return to work.

In the coming weeks, Inbar says he plans a demonstration with area firefighters at a training facility in Dallas, to show them bots that can clear debris, fight fires and help perform rescues.

The fastest-growing sector of his business now is the cleaning robot, as the service industry, in particular, struggles with labor challenges, Inbar says. The Houston office just sold its first cleaning robot, Edwards said.

“There is more demand for cleaning automation, simply because people don’t want to do the job anymore,” says Inbar. “We are hearing from everyone, in every market sector, from hotels, to assisted living facilities, to warehouses, you name it, supermarkets — even movie theaters. They can’t find people to clean. Putting that on autopilot, in a way, is the solution."

Edwards and Inbar say RobotLAB’s customized local service and connection provides the missing integration link for many business owners, who are intrigued by robots but may be way of what is involved with the equipment.

“We are basically the car dealership model of robotics,” Inbar says.

Christina Garavaglia, executive director of the Southeast Texas region of the Texas Restaurant Association, says the industry usually adapts cutting-edge technology early on, and robots are no exception.

“One of the primary reasons for this is that technology, hopefully, if it does what it’s intended, provides a lot of efficiency, and can help with some of the very tight margins that all of our restaurants work with,” she says.

Local restaurateurs have generally had positive reactions to robots, she says.

Eric’s Restaurant at the Hilton University of Houston Hotel was the first Texas restaurant to introduce a robot two years ago, as part of its student training, Garavaglia says, adding that she expects more restaurateurs to come on board.

The industry has “barely scanned the surface” in leveraging the potential for robots to maximize efficiency and create a unique customer experience, she said.

Jim Lewis, president of AREA 254, a 45,000-square-foot entertainment complex in Killeen, purchased three robots from RobotLAB and began using them in January.

The robot keeps the food warm, in its enclosed shelves, and frees up the servers. One robot can carry up to four pizzas, and go from table to table in one trip, directed by a software system activated by the QR code order at the table. And, just as important for Lewis, the robots provide the “fun, cool factor.”

“People love it, and robots put smiles on people’s faces,” Lewis says. “My guess is that it will pick up a lot of steam, especially in the family entertainment space, where buildings are so big. The robot provides a very practical solution to moving food long distances.”

Inbar says his company does not want to replace human labor with his robots, rather enhance it and free up time for humans while filling a labor gap prompted by a shift that began in the wake of the COVID pandemic.

“This is where the challenge is. They need people to move boxes in warehouses, cook, and clean floors, so automation is the solution,” Inbar says.

Garavaglia says restaurant servers may even see their tips increase, as they can engage longer with customers as the robot handles other chores. The gap between the tip and the amount of work done to earn it would close, she explains.

Most high-end restaurants pride themselves on the customer experience, she said, and “that can only be provided by a human person.”

“Feeling a trust, sense of connection, that is really a human trait, a human characteristic. So long as that is the case, human servers and human employees will always be necessary,” she says.

New pilot program for air taxis, Project Nexus, takes flight in Texas

Project Nexus

By 2029, Texas skies could be buzzing with air taxis, much like they are with drones today.

To kick off the "Project Nexus" pilot program in Texas, U.S. Transportation Secretary Sean Duffy, U.S. Sen. Ted Cruz, and Texas Department of Transportation officials attended an event September 10 at Fort Worth Alliance Airport, which serves as the launchpad for a statewide pilot program that could result in air taxis, self-piloted planes, and vertical take-off-and-landing aircraft permanently buzzing across the skies of Texas.

It was the first demonstration in Texas of next-generation aircraft under the pilot program; Texas is the sixth state to participate in the program.

Air taxi service on the radar
The federal government has teamed up with aviation companies BETA Technologies and Joby Aviation, as well as the Texas Department of Transportation, to develop regional air taxi service in Dallas, Austin, San Antonio, and eventually Houston.

Roger Venables, Fort Worth’s aviation director, said in January that he foresees regular air taxi service becoming a reality in the next five years.

On September 12, a Joby-made electric air taxi took a roundtrip flight between Fort Worth Alliance and Dallas Fort Worth International Airport to test flight operations.

The mission was part of a five-day test involving Fort Worth Alliance and DFW Airport flights, and flights over the Fort Worth Stockyards, Toyota Motor North America’s Plano headquarters, and other sites.

A new facility at Fort Worth Alliance will be Joby’s long-term home for regional flight operations.

Building a 'framework' for electric aircraft
TxDOT said Project Nexus is aimed at creating “a scalable system” to connect urban areas, rural communities, and neighboring states as air mobility technology advances.

In a TxDOT release, Marc Williams, the agency’s executive director, said the pilot program will “build a framework for how electric aircraft could one day connect people, goods, and communities across the state.”

Three-phase project will test flight capabilities

Initial flights in the third-year pilot program won’t carry passengers, according to TxDOT. Instead, the flights will gather data, validate air travel routes, and help improve the safety of air mobility technology.

The first phase of the U.S. Department of Transportation’s Project Nexus will feature piloted aircraft such as helicopters and fixed-wing planes. CultureMap previously reported Plano-based VertiPorts by Atlantic, which develops takeoff and landing sites for airplane-helicopter hybrids, would be part of Project Nexus.

The second phase will involve testing airborne medical and cargo logistics. This includes transporting critical medical supplies or donor organs between rural and urban hospitals in the Austin and San Antonio areas.

In the third and final phase, passengers will fly aboard air taxis across the Texas Triangle. Dallas-Fort Worth, Austin, Houston, and San Antonio anchor the triangle.

“In Texas, we don’t wait for the future to arrive, we build it,” Cruz said in the TxDOT release. “The Lone Star State is pushing the boundaries by testing the next generation of aircraft through Project Nexus.”

“These technologies will connect communities, expand access to jobs and services, and strengthen supply chains,” the senator added. “What starts in Texas will help shape the future of aviation throughout the entire country.”

Houston-area NASA contractor plans Nasdaq IPO

going public

Webster-based NASA contractor Rothe Development Inc. has filed paperwork with the U.S. Securities and Exchange Commission to go public.

Rothe, a minority- and woman-owned business, hasn’t yet identified how many shares it will sell and how much money its IPO might raise. Rothe plans to offer Class B common stock on the Nasdaq exchange.

CEO Karen Wheeler-Hall owns all of the Class A shares and would retain majority control after the IPO, according to the SEC filing. The company plans to use $2.4 million of the IPO proceeds so Wheeler-Hall can pay off a loan from the seller for her 2021 acquisition of Rothe.

From last December to this May, the company raised about $2.1 million in a pre-IPO private placement at $1 per share, the SEC filing shows.

Rothe runs NASA training lab in Houston

Founded in 1967, Rothe supplies engineering, technology, operations and technical services to NASA, the U.S. Department of Defense, other federal agencies, commercial space operators, and regulated industries.

Rothe is likely best known for operating NASA’s Neutral Buoyancy Laboratory in Houston. The lab trains astronauts for spacewalks and simulates space missions. It supports NASA’s International Space Station and Artemis programs.

Company sees room for growth

In the SEC filing, Rothe said it operates in several expanding markets driven by rising investments, including space exploration, national security, cybersecurity and digital infrastructure.

“We believe these market trends create significant opportunities for continued growth across both government and commercial sectors,” the company said.

Rothe generated nearly $126.4 million in revenue last year, up from $117.3 million the previous year. However, the company swung to a $700,000 operating loss in 2025 versus $1.8 million in operating income in 2024.

At the end of 2025, Rothe’s workforce comprised 385 employees and 25 subcontractors. The company also works in the cybersecurity, computer engineering, software development, multimedia and communication, and commercial calibration sectors, according to its website.
