Adolescents from 40-plus countries convened in Houston to put their robotic skills to test at the annual FIRST Championship last week.

The massive robotics championship returned this year to the George R. Brown to conclude the 2021-22 season of the international program, which is aimed at preparing youth ages 12 to 18 for the future through various robotics challenges and competitions.

The theme of this year’s season was FIRST FORWARD, in which students were challenged to think of new ways to overcome transportation challenges, “from the shipment of packages in rural and urban areas, to disaster relief delivery and high-tech space transit,” according to a release from the STEM organization.

The season was sponsored by California-based semiconductor company Qualcomm and was inspired in part by the UN Sustainable Development Goal of building resilient infrastructure, promoting inclusive and sustainable industrialization, and fostering innovation, according to the statement.

“I have met so many great students, volunteers, mentors, alumni, and sponsors who truly embody the FIRST mission and core Values," FIRST CEO Chris Moore says in a statement after the event. "People who strive to be gracious professionals who innovate, compete, and collaborate with equal energy. People who share our common passion for science and technology as a force for good with the world. The rewards of your efforts don’t stop at this event.”

Teams competed in final matches for FIRST's two major competitions.

In the FIRST Robotics Competition, which featured the RAPID REACT Game presented by Boeing, students were required to reimagine the future of his-speed transport with strict rules, limited resources, and time limits and using autonomous and driver-operated skills.

More than 3,200 teams competed during this game throughout the 2002 FIRST season and 454 teams advanced to the championship at the GRB. Team 1629 from Accident, Maryland, took home the top prize in this competition. Other teams from Austin, New York, Hawaii, Mexico, and Turkey were finalists.

In the FIRST Tech Challenge, teams were asked to think like engineers, building robots from reusables kits in the game FREIGHT FRENZY presented by Raytheon Technologies. Thousands of teams competed in this event throughout the season with 160 teams advancing to Houston. Team 8565 (the TechnicBots) from Plano won the top award.

A FIRST LEGO League challenge was also open to younger students, ages 4 to 16, and the championship. Also during the event, actress and director Gillian Jacobs accepted an award for the film "More Than Robots," which follows four teams as they prepare for the 2020 FIRST competition. The film premiered at SXSW last month and is featured on Disney+.

“I named this documentary ‘More Than Robots’ because as you all well know better than anyone, FIRST is about so much more than robots. I learned that it's about teamwork, compassion, friendship, learning new skills, and challenging yourself to do things you never dreamed you were capable of," Jacobs said at the event.

FIRST's 2022-23 season, dubbed FIRST ENERGIZE, will focus on innovative energy solutions. The season opens in May. Learn more here.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
