Researchers developed a quadruped robot with an arm to collect air samples from hazardous environments.

Researchers have developed a dog-like quadruped robot equipped with a mechanized arm to collect air samples from hazardous environments, such as abandoned buildings or fires. The robot navigates and delivers samples to a person for screening of potentially hazardous compounds. This robot assists in testing air for dangerous chemicals in risky workplaces or after accidents, keeping humans out of harm's way.
