Future robots require interactive communication and tasksharing capabilities in the context of a social interaction with a human partner. Along with evolutionary computer programming either with self or behavior-based learning algorithms, ergonomically design and multi-interaction sensing systems are among the most important components for robot to face the challenge and needs from modern society. Sensors are a critical part of any robot, whether autonomous or teleoperated, or whether for land,

... space or underwater applications. Sensor provides important information about the environment and also to feedback information about the internal operation and motion of the robot's body parts. There are many types of sensors for use in robots and they have served robot based on its nature and sensing principles. Future interactive robots require many types of sensors to integrate and interactively communicate each other as sensing fusion to expend the capability of robots. This special issue focuses on some of the issues and challenges that arise when sensors interactively used in robot systems. It covers from developmental up to the system architecture and applications, which each of them potentially expand the capabilities of the robot system during interaction with human partner. Some of the articles also discussed about de-
