Patriot Profile: Christopher Vo

By Catherine Probst on April 8, 2014


Year: Doctoral student

Major: Computer Science

The Washington, D.C., region is a hotbed of personal drone development, and PhD student Christopher Vo is getting in on the action. The drones he develops—and he’s built nearly 15 of them—are called quadcopters because they are lifted and propelled by four rotors. You may have even seen Vo’s quadcopter zooming through the air when he was producing an aerial video of the Fairfax Campus. Watch video.

What Sets Him Apart: Also called unmanned aerial vehicles, drones are typically associated with military operations, but Vo’s research takes a different approach. Today’s small drones, often no larger than a Frisbee, are sophisticated little machines that can do lots of things, such as carry high-definition cameras and navigate between waypoints via global positioning systems. For the past two years, Vo has been working on motion planning algorithms that allow drones to fly autonomously using the data from an attached camera. He likens his research to herding a flock of sheep. A shepherd faces many obstacles and restraints while trying to gather his sheep. By pairing the drone with artificially intelligent shepherding behaviors, it is possible to perform the shepherding task autonomously or assist a shepherd in his tasks like a robotic sheepdog. “When used correctly, unmanned aerial vehicles can provide perspectives with our sensors that we may not otherwise have,” says Vo. “This information can be used to assist people or ground robots to accomplish their goals.”

Drone Education: For the past year, Vo has served as director of education for the D.C. Area Drone User Group. With more than 700 members, the group seeks to promote the responsible use of flying robots for community service, artistic, entrepreneurial, and recreational purposes. “One of the main goals of the group is to educate people about the technology of drones and their socially beneficial uses,” says Vo. “Drones get such a bad rap, but there are so many great uses for them such as monitoring endangered species, inspecting bridges for cracks and structural failures, search and rescue, or scientific research.”

The Positive Side of Drones: Vo notes that there aren’t any Federal Aviation Administration regulations against flying small drones, yet. “Right now, small drones operate under the same rules as radio-controlled airplanes and are typically supposed to fly below 400 feet,” he explains. The Drone User Group is “thinking of ways to push the positive uses of drones and dispel the negative assumptions that drones are only used to invade people’s privacy.” Vo also hosts workshops and seminars to teach individuals how to build and safely use drones. “We’re all about promoting the use of flying robots for artistic, humanitarian, and recreational purposes.”

What the Future Holds: Eventually, Vo would like to start his own business in the drone industry. In particular, he is interested in using drones to work on motion control for cinematography. “It’s an exciting time for the future of drones,” he says. “We could achieve perspectives that would be difficult or even impossible before, such as sending cameras through small openings, filming dangerous stunt action, or following a subject very closely.”

  1. Great article! I am an Animal Care Specialist at the National Zoo. I am also from the Mason Class of 2009. I would really like to get in contact with Christopher Vo to discuss his project and it’s application to my work. Thank you,
