Robots may soon help soldiers on battlefield
Scientists have developed a new technique that allows robots to autonomously navigate in different environments and carry out actions a soldier would expect from a team mate on the battlefield. The technique, developed by researchers at the US Army Research Laboratory (ARL) and Carnegie Mellon University in the US, helps quickly teach robots novel behaviours with minimal human oversight.
“If a robot acts as a teammate, tasks can be accomplished faster and more situational awareness can be obtained,” said Maggie Wigness, from ARL. “Further, robot teammates can be used as an initial investigator for potentially dangerous scenarios, thereby keeping Soldiers further from harm,” said
Wigness.
To achieve this, Wigness said the robot must be able to use its learned intelligence to perceive, reason and make decisions.
“The learning process is fast and requires minimal human demonstration, making it an ideal learning technique for on-the-fly learning in the field when mission requirements change,” she said. Researchers focused their initial investigation on learning robot traversal behaviours with respect to the robot's visual perception of terrain and objects in the environment.
More specifically, the robot was taught how to navigate from various points in the environment while staying near the edge of a road, and also how to traverse covertly using buildings as cover.
