Abstract
In order for a robot to operate in a place like domestic, it is necessary to collect various environment information. In the information which is needed in case something is made to work to a robot, the information which cannot be acquired using a sensor exists plentifully. So, in this research, a mark is used for construction of the environment where a robot operates. The mark is realized from the landmark and the QR code. The position posture relation between a robot and a work subject is acquired by sticking a mark. The information peculiar to a subject which is needed in case it works in the QR code is indicated. Autonomous operation of a robot was performed by using the information on a mark.
