Algorithm of Path Planning for Wheeled Mobile Robot Base on Time Optimization

Time optimal path is needed in time sensitive occasions such as robot competition. In this paper, kinematics model of wheeled mobile robot is established first, and the path mode which suitable for wheeled mobile robot is analyzed. Then use the experience of tangent method, a new algorithm for time optimization is presented by adding virtual circles in the beginning and the end of the path, thereby the position and orientation of the robot are integrated in one path. The simulation result shows that the method could generate global optimal path. Besides, it has high search efficiency and good adaptability.

Research on Quick Temperature Measurement Algorithm Based on Linear System

In view of the deficiency of existing quick temperature measurement algorithms, a new algorithm based on prediction model of linear system is presented. The true temperature value around the sensor can be predicted by this algorithm according to the unit-step response model and the output of the temperature measurement element. The simulation results show that the method has a wide accommodation, short response time and is simple in calculation. Meanwhile, the interference caused by sampling error can be reduced after wave filtering. In addition, the algorithm is not limited to the first order system. Other types of linear system can be also applied for fast prediction.
