Shallow domain knowledge, such as labels attached to objects and places is necessary for task planning of mobile robots. In order to save energy and protect environment for robots, a fast and effective semantic building map method based on sonars, vision and audio is proposed. Firstly, humanoid robot Nao builds the border map of an unknown environment by its sonars. And then Nao follows a red ball...
Indoor cleaning robots often work in peopled surroundings. Therefore, cleaning robots in domestic homes should not only clean efficiently but also harmoniously integrate with humans. This paper proposes to add cognitive abilities to intelligent cleaning robots, including environmental cognition, dynamic obstacles, and cleaning tasks. These cognition abilities are implemented by very simple, yet efficient...
This paper proposed a method of map building combined sonar and human-robot interaction. Robot builds the border of an unknown environment by its sonar, and then a user controls the robot to walk forward, back, left and right so that the robot is able to walk around an obstacle along its border. By this way, the robot walks around all obstacles in the environment one by one while a map building method...
A concept of local gray entropy is introduced to solve the problem of the human body detection difficulty under the dim contrast environment. This paper analyses the trait of local gray entropy, and then proposes an algorithm of human target detection based on the trait, which is according to the principle that local gray entropy could reflect the discrete level accurately, and it has no relationship...
Based on the database of typical weather condition in northern cold region of China, this paper compares different function buildings' cooling and heating load's imbalance rate. The effect of different building functions on cooling and heating load is analyzed. On the above basis, underground heat exchanger pipe group model of ground source heat pump (GSHP) is established. As a monthly time step to...
In this paper, the quantitative evaluation model- attribute recognition model is used to identify underground space's air quality. Three types of method are applicated to empower the objective weights, which avoid determining the weights subjectively. In the light of actual description of the process, the ultimate evaluation of underground space's air quality is fit for the result of reality.
