Researchers Devise a Method to “Communicate” with Plants via Electrical Signals

The fact that plants emit barely perceptible electrical signals to sense and respond to their environments has been known for decades. And yet, due to the weakness of those signals, as well as the difficulty of achieving reliable transmission due to the irregular surfaces of many plants, harnessing that power has been a real challenge. Now, however, researchers from the ...

Behavior-Tree-Based Person Search for Symbiotic Autonomous Mobile Robot Tasks

Social robots can help humans in various aspects of everyday life. However, they usually cannot perform physical operations, such as opening doors or operating elevators. Therefore, the capability of finding a person to help could compensate for this weakness. A recent paper on arXiv.org proposes to use the Behavior Tree (BT) framework for finding people in an open space. It ...
