This paper considers the computation of motion strategies to efficiently build polygonal layouts of indoor environments using a mobile robot equipped with a range sensor. This problem requires repeatedly answering the following question while the model is being built: Where should the robot go to perform the next sensing operation? A next-best-view planner(More)
A new method for target motion parameter estimation is presented in this paper. A new objective function is proposed to avoid phase unwrapping procedure in the original method. The proposed method is more robust and accurate than the original one because it does not introduce any extra errors. To find a global optimum value, DE algorithm with a modification(More)
The processing of image object of visual sensor is a key issue in robot intelligent control. A new method for object recognition based on Radon transform is proposed. On the basis of image preprocessing, the algorithm for extracting the shape features of image object at different angles based on Radon Transform (RT) is given. To increase the efficiency of(More)
Most automatic steering systems for large tractors are designed with hydraulic systems that run on either constant flow or constant pressure. Such designs are limited in adaptability and applicability. Moreover, their control valves can unload in the neutral position and eventually lead to serious hydraulic leakage over long operation periods. In response(More)
As the major factor to driving safety, human error is induced both by inner factors and external environment factors. But until now, the systematical method for predicting driver’s behavior failure has not been put forward yet. Therefore, based on the contextual control model used in CREAM, the effects of the driving environment to the driver’s behavior are(More)
The expert system for tractor cab man-machine interface evaluation was developed using Visual C++ and CLIPS that is one of the expert system tools on the re-development platform of CATIA. The system structure and functions were presented. The knowledge expression, reason mechanism and the design and build method of knowledge base were put forward. The(More)
