The diagram of recognition system is illustrated as Figure1. This system contains a Kinect sensor and personal computer in which the Kinect sensor is used to capture the user pose and the recognition algorithm is implemented in the personal computer. The captured image can be transform to a skeleton image by Kinect Software Development Kit (Kinect-SDK). The information of skeleton image can be imported to self-organizing map algorithm to obtain the posture. The recognition can provide a related command to control the multi- robot systems.
