Researchers at George Washington University developed a method for remotely driving a miniature video capsule into problem areas of the stomach.

Physicians can direct the capsule to these areas to visualize and photograph potential problem areas. This technology utilizes an external magnet an handheld video game-style joysticks. Altogether, it enables physicians to move the capsule in three dimensions within the stomach, nearing the capabilities of traditional, tube-based endoscopy. Medical technology company AnX Robotica funded the research. The company created the capsule endoscopy system used in the study, called NaviCam.

Andrew Meltzer, a professor of emergency medicine at the GW School of Medicine & Health Sciences, led the research. According to GW’s website, he gained interest in this type of endoscopy after seeing firs…

Endiatx’s pill-sized robot sees and swims inside the stomach

An unconventional CEO and his team take aim at endoscopies with faster, cheaper stomach imaging — and that’s just the start. Welcome to the era of tiny robots inside the body.

As he prepared to swallow his robot for the first time, Torrey Smith’s doctors warned that the battery was his greatest threat.

If the capsule came apart and the battery burned the tissue lining his stomach, it would only be the beginning of a very bad experience.

“I was just hoping that we would get any kind of a positive signal that we were on the right track,” Smith, co-founder and CEO of Endiatx, said of the June 2020 test. “At that time, our radio bandwidth was so limited. We were pushing 48 pixels square of grayscale, not even color, at just a few frames per second. The worst video quality you could imagine —…
