ロボット動作支援のためのインテリジェントマークとその認識デバイスの開発  [in Japanese] Development of an Intelligent Mark and Its Recognition Device to Support Robot Activities  [in Japanese]

This study develops an intelligent mark and its recognition system. Robots need information about its environment and/or objects in order to do effectively the tasks required. Intelligent marks are used by attaching on objects and can send the information such as object category, weight, and so on by an infrared ray communication. Robots get the data of an object by the recognition system. The recognition system also measures relative position of an object by calculating the difference of reaching time between infrared rays and ultrasonic waves sent from the intelligent mark. This study evaluates experimentally the communication range and the accuracy of relative position measurements to confirm the applicability of the intelligent mark and its recognition system.
