    Abstract: A communication system is provided that includes a network node, a first terminal which supports an EVS (Enhanced Voice Service) codec, and a second terminal. The EVS codec supports an AMR-WB (Adaptive Multi Rate Wideband) codec compatible mode and an AMR-WB codec non-compatible mode, the AMR-WB codec having a dedicated payload format, where the AMR-WB codec compatible mode is compatible with an AMR-WB codec and the AMR-WB codec non-compatible mode is non-compatible with the AMR-WB codec. The first terminal and the second terminal negotiate the AMR-WB codec non-compatible mode in a session negotiation to select the AMR-WB codec non-compatible mode to be used for the communication between the first terminal and the second terminal when the communication starts.

    Abstract: A cleaning robot which performs a predetermined task while autonomously moving includes: a driver which makes the cleaning robot move; an image capturer which detects a movement state indicating whether a different cleaning robot existing in front of the cleaning robot is moving along an obstacle, a direction in which the different cleaning robot exists relative to the cleaning robot, and a distance between the cleaning robot and the different cleaning robot; and a following run controller which controls the driver in order for the cleaning robot to move following the different cleaning robot while keeping a position diagonally behind the different cleaning robot at an opposite side of the different cleaning robot from the obstacle, if the movement state indicates that the different cleaning robot is moving along the obstacle.
