Robovision, now in 3-D

Soldiers and first responders may soon have a better way to evaluate the interior of dangerous structures, thanks to a joint project between Missouri S&T and the University of Missouri-Columbia.


As part of the project, which began in 2008, students at Missouri S&T built a remote-controlled robot equipped with an infrared camera and LIDAR (light detection and ranging) technology. Like radar, LIDAR sends out signals, in this case millions of laser points, to bounce off objects and provide feedback. The LIDAR-equipped robot then wirelessly relays detailed images to a laptop computer.

“We can get a 3-D map of rooms by sending the robot inside or having it look through a window,” says Norbert Maerz, associate professor of geological engineering at Missouri S&T. “Even when you can’t see through windows, you can still scan through them with LIDAR. Using this information, soldiers or first responders could evaluate safety issues and determine strategies.”
Maerz and his students have used their prototype to map the inside of houses, businesses, Missouri S&T buildings, chambers in S&T’s Experimental Mine and cave passages in the Mark Twain National Forest. “In theory, you could deploy this technology inside caves where terrorists might be hiding,” Maerz says.

Honoring new academy members

In October, 12 alumni and friends were inducted into Missouri S&T academies. Academy membership recognizes careers of distinction and invites members to share their wisdom, influence and resources with faculty and students. Some academies hold induction ceremonies in the fall, others in the spring.

Boosting cyber-physical security

A wide array of complex systems that rely on computers — from public water supply systems and electric grids to chemical plants and self-driving vehicles — increasingly come under not just digital but physical attacks. Bruce McMillin, professor and interim chair of computer science at Missouri S&T, is looking to change that by developing stronger safeguards […]

MXene discovery could improve energy storage

In spite of their diminutive size, 2-D titanium carbide materials known as MXenes are “quite reactive” to water, a discovery S&T researchers say could have implications for energy storage and harvesting applications such as batteries, supercapacitors and beyond. Their findings were published in 2018 in the American Chemical Society journal Inorganic Chemistry.

A faster charge for electric vehicles

One drawback of electric vehicles (EVs) is the time it takes to charge them. But what if you could plug in your EV and fully charge it as quickly as it takes to fill up a conventional car with gasoline? Missouri S&T researchers, in collaboration with three private companies, are working to make speedy charging […]
