MIT roboticists have developed a system, called "Relevance," to help robots focus on relevant features in a scene for assisting humans.
The Relevance approach enables robots to determine a human's objective using cues like audio and visual information.
A robot can then identify objects most likely to be relevant in fulfilling the human's objective and act accordingly.
In an experiment simulating a conference breakfast buffet, the robot successfully assisted humans in various scenarios with high accuracy.
The robot predicted a human's objective with 90% accuracy and identified relevant objects with 96% accuracy.
This method not only improves a robot's efficiency but also enhances safety by reducing collisions by over 60%.
The system mimics the human brain's Reticular Activating System to selectively process and filter information.
It consists of phases like perception, trigger check, relevance determination, and object offering based on relevance.
The researchers aim to apply this system in smart manufacturing, warehouse environments, and household tasks for more natural human-robot interactions.
The team's goal is to enable robots to offer seamless, intelligent, safe, and efficient assistance in dynamic environments.
