Researchers from the University of Nebraska (USA) have successfully developed a robot capable of moving inside the human abdomen, allowing doctors to have a clearer view of the surgical area.
In addition, the robot is equipped with a needle for biopsy sampling.
The robot consists of two rotating aluminum tubes connected by a thick shaft that houses a camera. The spiral design on the surface of the tubes enables the robot to grip the abdominal wall and maneuver around without damaging tissue.

With a diameter of only 15mm, the robot can be inserted into the body through a small incision in the abdomen, similar to what doctors do during laparoscopic surgery. The robot is operated via a control stick connected to a computer screen.
Dmitry Oleynikov and his colleagues have used this type of robot to explore the abdominal cavity of live pigs and assist in their gallbladder surgeries. They are currently working on improvements to make the robot easier to maneuver.
It is noted that multiple robots can be introduced into the abdomen to provide a clearer view of specific areas from different angles.
