In order to improve the delight of life and the efficiency of nursing care for the elderly or disabled persons in a wheelchair, a method of automatic tracking caregiver was proposed in this paper. The video sequence image acquired by the visual sensers installed in a wheelchair is taken as the research object. Firstly, a fast motion estimation and compensation algorithm based on brisk operator is...
To better solve the optimization problem of fuzzy neural network (FNN), a kind of method based on artificial fish swarm algorithm (AFSA) is proposed in this paper. Aiming at the structure optimization problem of FNN, AFSA-FNN1 is established and realizes the simplification of fuzzy rules. Aiming at the parameter optimization problem of FNN, AFSA-FNN2 is built and realizes the acquisition of parameters...
The UP-Voyager II autonomous mobile robot as the experimental platform, a kind of fuzzy adaptive PID algorithm is presented and used for the robot's motion control. Aiming at the interferential, time varying and nonlinear problems in motion control, the design method of fuzzy adaptive PID is put forward. This method may dynamically adjust proportional coefficient (Kp), integral coefficient (Ki) and...
A kind of experiment research method was proposed in this paper to further verify dynamic path planning method in [1]. Firstly, MATLAB engine method was chosen by comparing a variety of mixed programming methods of MATLAB and Visual C++ (VC). Secondly, two experiments were studied by using two tracked robots. The first experiment was performed in static environment and the second experiment was performed...
To realize location and navigation, the robot need exactly know the position of artificial landmark in environment. In this paper a kind of artificial landmark recognition method based on omni-vision sensor is proposed. This method has three steps: color feature extraction, region segmentation and feature screening. And this method has the characteristic of simple arithmetic and well real-time quality...
