A navigation system developed by University of California, San Diego (UC San Diego) computer scientists aims to improve the ability of robots to navigate busy clinical environments, especially hospital emergency departments.

The Safety Critical Deep Q-Network (SafeDQN) navigation system is built around an algorithm that factors in the number of people clustered in a space and the speed and abruptness with which they are moving and directs robots to move around them.

The researchers trained the algorithm using a dataset of more than 700 YouTube videos, mainly from documentaries and reality shows.

When tested in a simulated environment and compared to other state-of-the-art robotic navigation systems, the researchers determined that SafeDQN found the most efficient and safest paths in all cases.
