The drones are coming! Showcase highlights use of unmanned vehicles to map critical watersheds

OSU students showcased their use of unmanned aerial vehicles and boats to map Oklahoma lakes

Early morning anglers casting into Grand Lake’s Horseshoe Cove this past summer might have done a double-take if they spotted a lime-green kayak plowing across the water with no human pilot aboard.

What they were witnessing was MANUEL, a creation of Oklahoma State University engineering graduate student Muwanika Jdiobe.

MANUEL – an acronym for Mobile Autonomously Navigable USV for Evaluation of Lakes – was created by Jdiobe as a project for OSU’s Unmanned Systems Research Institute (USRI).

Jdiobe recently made a virtual presentation about MANUEL and what his research at Horseshoe Cove uncovered at the Oklahoma City Innovation District’s Student Showcase on Unmanned Systems.

The showcase was the third in a series of student showcases presented by the Innovation District in conjunction with OSU’s USRI.

“Our vision is to get the best minds in the same room to meet, share research, information and ultimately, drive innovation in Oklahoma and around the country,” said Austin Bowles, the Innovation District’s digital marketing director.

Jdiobe was one of two OSU students affiliated with USRI who described projects that measured water depth and quality or mapped invasive vegetation on a lake that provides critical drinking water.

Before it was deployed on its Grand Lake mission, MANUEL was outfitted with an electric motor that provided propulsion, along with GPS equipment that allowed precise autonomous navigation, along with sensors that collected information on water quality and depth.

“The whole time I was sitting on the shore just observing her execute her mission,” Jdiobe said. “After every mission, MANUEL has to return to the point at which she was launched so we can extract all the data that was collected.”

The project was conducted in coordination with OSU environmental scientists who sought data about the lake and how pollution was impacting its depth and water quality. The goal is to better understand and prevent harmful algal blooms caused by agricultural runoff. One such bloom shut down Grand Lake on July 4, 2011, its busiest day of the year.

“MANUEL can reach very difficult places that other technologies cannot reach,” Jdiobe said. “We came to learn that MANUEL can actually work in very harsh conditions, even when we have strong winds and heavy rainfalls.”

The second presentation at the Student Showcase involved the mapping of Stillwater’s Lake Carl Blackwell on behalf of OSU and the City of Stillwater.

OSU mechanical and aerospace engineering graduate student Andrew Cole described how two unmanned aerial vehicles – drones – were used to map the lake and assess the growth of unwanted vegetation.

“The problem we applied this to was Floating Yellow Heart, which is an invasive species that was found in Lake Carl Blackwell, the main water source for the OSU campus and parts of Stillwater,” Cole said. “It is a lily pad that grows in such dense mass that it blocks out the sunlight and chokes out natural plants.”

The project involved outfitting two drones with cameras – some of them multispectral which filters certain light waves – to make high-resolution photos of the lake.

Using what is known as photogrammetry software that stiches the photos together to make a composite photo, scientists were able to assess the exact locations of the Floating Yellow Heart and apply herbicide to kill it.

The path the drones followed was plotted beforehand, so the unmanned aerial vehicles flew a precise route.

“With this automation method, we can actually fly the lake by one person in about two hours, or two people in one hour because you have two vehicles in the air,” Cole said. “Using unmanned aerial systems is a cheap and efficient way to get data that a lot of times you can’t get any other way.”

Added Victoria Natalie, program manager at OSU’s Unmanned Systems Research Institute: “With drones coming into their own as a research tool, we’ve really been able to expand different ways of getting information across, collecting data and furthering research.”

Natalie is leading USRI’s expansion in the Oklahoma City Discovery facility, recently donated to OSU, which will enable closer connections between OSU and the Oklahoma City Innovation District.

Oklahoma Innovators: NASA awards SBIR contract to Stillwater’s XploSafe

I’ve worked on the periphery of Oklahoma City’s startup community for about two decades, first as a business news reporter at The Oklahoman newspaper, then as communications specialist for i2E, Inc., and now as a freelance writer.

It’s pretty exciting to see local companies announce a breakthrough discovery, a new product or investment that will carry their innovation into the commercial market.

Unfortunately, many worthy developments don’t always make it onto the pages or websites of local news media, whether it’s a newspaper, television or even digital news site.

There are hundreds of voices seeking media attention every day, so it can be pretty daunting to attract the attention of an editor or reporter.

So, I’ve decided that this blog can be a conduit for my entrepreneur friends to find an audience for their news. From time to time, I’ll publish news that comes my way that hasn’t found its way into any other media.

For example, today I want to share some exciting news from a Stillwater-based company called XploSafe. If you don’t know XploSafe, the company describes itself as a provider of “critical safety solutions for homeland security and chemical safety.”

XploSafe has its roots in the Oklahoma State University laboratories of co-founders Allen Apblett, Ph. D., and Nick Materer, Ph. D., both chemistry professors, along with former OSU graduate student Shoaib Shaikh, also a co-founder and now CEO.

I learned about XploSafe more than 10 years ago when Shoaib pitched the concept in the Donald W. Reynolds Governor’s Cup business plan competition (now known as the Love’s Entrepreneur’s Cup).

Since then, XploSafe has expanded its mission beyond explosive detection to chemical vapor sampling and other areas where detection of potentially dangerous materials is critical.

Recently, XploSafe was awarded a $125,000 Phase 1 Small Business Innovation Research (SBIR) contract from NASA to develop specialized air filtration units for the next-generation of American space suits.

XploSafe released the exciting SBIR news in mid-October, but received little media attention. I invite you to read their announcement from October 15 below.

Stillwater, OK – 15 October 2020 – XploSafe announced today that it has been awarded a Phase I SBIR contract from the National Aeronautics and Space Administration (NASA) to develop specialized air filtration units for the next-generation of American space suits.

The award amount is $125,000 over a six-month period.

These filtration units will help keep the space suit’s internal air-flow free of any toxic, trace contaminants, which naturally build-up while astronauts use their suits. XploSafe aims to capture these contaminants within their proprietary sorbent media, which could then be vacuum regenerated to enable longer spacewalks and substantially improve time in-suit over the duration of a mission. Such a capability will be required for NASA’s upcoming Artemis missions, in which the United States intends to return to the moon by 2024.

The design of XploSafe’s filtration units would provide astronauts with safer air to breathe, as well as lighter, easier to use suits. XploSafe’s filtration unit would be housed within the Exploration Portable Life Support System (xPLSS) backpack of the next-generation xEMU suits, alongside other critical life-support systems. The company holds multiple patents for vapor nanoconfinement technology that facilitates high-capacity absorption, stabilization, and consistent recovery (removal) of a wide range of volatile, semi-volatile, and even reactive organic compounds.

XploSafe’s Operations Manager, Michael Teicheira, had the following to say: “we are ecstatic about this opportunity to showcase the research and development efforts of XploSafe here on the national and even international stage. The prospect of our products enabling astronauts to spend more time in space is an enthralling one, and we are so grateful for this opportunity to show what a small Oklahoma research company can achieve.”

XploSafe based in Stillwater, Oklahoma, is a provider of critical safety solutions for homeland security and chemical safety. Their XploSens explosives detection, XPell peroxide safety products, and XCel+ chemical vapor sampling badges are used by first responders, industrial safety officers, threat assessment officials, and laboratory and chemical manufacturing personnel all over the world.

Congratulations to Shoaib and the XploSafe team.
