A team of Rice University engineering students has developed a new way for underwater robots to move around, save power and work more efficiently and quietly.

The robot uses reversible hydrogen fuel cell-based buoyancy control devices that convert water into hydrogen and oxygen (and the reverse) using electricity. Traditional underwater robots use thrusters or large pumps and propellers to change and hold depth, which can be heavy, have higher costs and use more energy. The use of reversible hydrogen fuel cells with balloons, allows the new robot to smoothly adjust its depth with less energy usage, according to a statement from Rice.

The project was part of a year-long senior design capstone by six students, known as Team Bay-Max, in Rice's Oshman Engineering Design Kitchen.

The students—Andrew Bare, Spencer Darwall, Noah Elzner, Rafe Neathery, Ethan Peck and Dan Zislis— won second place in the Willy Revolution Award for Outstanding Innovation at the Huff OEDK Engineering Design Showcase held at the Ion last month.

“Having spent a year on it now and putting so much time into it, getting to see the result of all that work come together is really rewarding,” Peck said in the statement.

“With a project like this, integration was critical,” Zislis added. “Another takeaway for me is the importance of determining a clear scope for any given project. With this robot, we could have focused on a lot of different things. For instance, we could have worked on improving fuel cell efficiency or making a robotic arm. Instead, we chose to keep these other elements simple so as not to divert focus away from the main part, which is the buoyancy control device. This kind of decision-making process is not just part of good engineering, but it’s relevant with everything in life.”

Elzner, for instance, focused on the dashboard that the robot feeds information to as it collects data from different sensors. It displays core system information, real-time graphs of the robot’s location and a simulation of its relative orientation, according to the statement.

Darwall, took a " deep dive into control theory and learn(ed) new software" to incorporate the video game joystick that allows the robot to combine manual control with an automatic stabilizing algorithm.

The proof-of-concept robot has potential applications in environmental monitoring, oceanographic research, and military and industrial tasks, according to Rice.

The team based the project on an academic paper by Houston researchers that showed that fuel cell-enabled depth control could reduce autonomous underwater vehicles’ energy consumption by as much as 85 percent.

It was authored by Rice professor Fathi Ghorbel and members of the University of Houston's Zheng Chen lab.

“This collaborative research aims to develop tetherless continuum soft engines that utilize reversible proton exchange membrane fuel cells and water electrolyzers to drive volume-mass transformation," Ghorbel said in a statement. "Through this design project, the BayMax team proved the efficacy of this technology in AUV interaction with the physical world.”

Ghorbel, Rice mechanical engineering lecturer David Trevas, and Professor in the Practice, Electrical and Computer and Engineering Gary Woods mentored the team.

Last month Rice also held its 24th annual Rice Business Plan Competition, doling out more than $1.5 million in investment and cash prizes to the top teams. Click here to see what student-led startups took home awards.

Houston mental health nonprofit expands platform statewide to connect more Texans with care

access granted

As mental health conversations evolve, the necessary pivot becomes how organizations across Texas navigate improved ways to help people access the care they need before their challenges become crises.

That’s why Mental Health America of Greater Houston recently announced that it is expanding its Care Connect platform statewide.

The expansion will address perhaps the most persistent barrier to behavioral healthcare—helping people find and navigate services that already exist.

Care Connect’s extended reach comes at a time when more than 3.5 million adults in the state live with some kind of mental health condition and scores of those in need continue to struggle with accessing care despite the growing awareness of mental health needs.

According to President and CEO Renae Vania Tomczak, Care Connect’s main goal was to remove as many obstacles as possible that Texans face when seeking mental health support.

“Care Connect was about a two-year planning process,” Tomczak says. “It really began with asking what challenges people in the Greater Houston Area were facing regarding mental health. It’s not just accessing care, but the difficulty in navigating the mental healthcare system.”

While provider shortages remain a challenge in some communities, Mental Health America of Greater Houston found that many individuals and families struggle simply to determine where to turn, how to identify the right provider and whether services are affordable.

“We wanted to make it easier for people who have questions, who may never have had a mental health challenge before, or they’re a caregiver for somebody who has a mental health issue,” Tomczak says. “We wanted to be the place that people can come to get their questions answered and be connected to care.”

Care Connect combines a vetted network of more than 1,000 providers and services across Texas with personalized navigation support.

Searches generate care results based on insurance coverage, language preferences, ZIP code and clinical specialties.

Additionally, one-on-one guidance and follow-up support are provided by bilingual resource specialists.

The platform also seeks to address affordability, one of the most significant barriers to mental healthcare access. Through participating providers, eligible individuals can receive six to eight counseling sessions at no cost.

“We have several providers who are willing to provide six to eight counseling sessions at no cost for people who do not have the means to pay for services themselves,” Tomczak says.

When provider matches are unavailable, the organization can connect individuals with master’s-level mental health professionals working under the supervision of licensed clinicians.

The statewide rollout builds on the platform’s early success in the Houston region, where it has helped thousands of individuals connect with mental health resources since launching last fall.

According to Tomczak, the decision to expand was driven in part by growing demand from outside the organization’s traditional service area.

“Last month we decided to take this program statewide,” she says. “It’s not just Houston that can use help in connecting to appropriate mental health services, but the whole state.”

The Care Connect program’s promotion through healthcare providers, community organizations and public-sector partners across Texas is now one of Mental Health America of Greater Houston’s top priorities.

Their goal is to create a stronger referral ecosystem that ultimately helps those who need access to mental health care more quickly.

To facilitate that, the organization has also added free mental health screenings to its website so that users will better identify any symptoms related to anxiety, depression and other conditions.

“Once they do that, then where do they go?” Tomczak says. “They’re not sure who to call and who can help them. At that point, we hope they’ll call us and talk to somebody live who can answer their questions and help them get started on the right path to improving their mental health.”

With eyes on the future, Tomczak believes public understanding of mental health has improved in recent years, particularly following the COVID-19 pandemic, which brought new attention to the effects of stress, isolation and uncertainty.

“The more we talk about it and have the opportunity to share that mental health conditions are traceable, the better,” she says.

According to Tomczak, long-term, Care Connect aims to reduce roadblocks that exist between recognizing the need for help and receiving it.

Ultimately, Care Connect hopes to create a robustly connected behavioral health system that gives Texans the ability to access mental health services swiftly and with confidence.

“No one should have to navigate mental health challenges alone,” Tomczak adds. “Care Connect is here to help connect people with resources, services and answers to ensure they get the care they need to take the next step toward better mental health.”

ExxonMobil sets date to make Texas its legal HQ

save the date

Energy giant Exxon Mobil Corp. has set a date to move its legal headquarters to Texas.

The Spring-based company announced this week that the redomiciliation from New Jersey to Texas is expected to be effective July 1. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March, and shareholders approved the move to Texas at the company’s annual meeting in May.

As part of the move, ExxonMobil Holdings Corp. will replace Exxon Mobil Corp. of New Jersey and become the publicly traded parent company. Exxon reports that its shares will continue to trade on the New York Stock Exchange under the ticker symbol “XOM,” and that shareholders do not need to take action.

At the time of the recommendation, Exxon said the move would not affect business operations, management, strategy, assets or employee locations.

Exxon Chairman and CEO Darren Woods added that the redomiciliation was in part due to Texas' business-friendly environment and policies.

"Over the past several years, Texas has made a noticeable effort to embrace the business community. In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value,” Woods said in a news release. "Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The Associated Press reports that about 30 percent of Exxon's employees work in Texas. Exxon's legal headquarters has been based in New Jersey since 1882, when it was Standard Oil Company.

Exxon moved its operational headquarters from Irving, Texas, to the Houston area in 2023.

Exxon was the highest-ranking Houston-area company on this year's Fortune 500 list, coming in at No. 9. Houston tied with Chicago for the second-most Fortune 500 headquarters on this year's list, with Texas leading the nation for the most Fortune 500 headquarters (57).

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”
