a new wildcard search method for digital dictionary based on Mobile Platform
International Conference on Artificial Reality and Telexistence, 2006Co-Authors: Xin Zhou, Yunlong Xu, Gongming ChenAbstract:This paper implements a digital dictionary system on the Mobile Platform and proposes a novel algorithm for the wildcard search problem. Our approach, which is based on the advanced trie tree, performs the wildcard search process in a cut-branch operation, which will reduce the search range largely. Thus, the efficiency of the algorithm is increased radically. In addition, compared with normal trie tree, the advanced one, which includes the fuzzy pointer field, makes it possible that the no-head wildcard search can be processed efficiently without linearly scanning all the word entries in the dictionary. At last, the new algorithm is easy to be implemented and experimental results show high robustness and efficiency on the Mobile Platform.

FPGA Implementation of an Embedded Robust Adaptive Controller for Autonomous Omnidirectional Mobile Platform
IEEE Transactions on Industrial Electronics, 2009Co-Authors: Hsu-chih Huang, Ching-chih TsaiAbstract:This paper presents an embedded adaptive robust controller for trajectory tracking and stabilization of an omnidirectional Mobile Platform with parameter variations and uncertainties caused by friction and slip. Based on a dynamic model of the Platform, the adaptive controller to achieve point stabilization, trajectory tracking, and path following is synthesized via the adaptive backstepping approach. This robust adaptive controller is then implemented into a high-performance field-programmable gate array chip using hardware/software codesign technique and system-on-a-programmable-chip design concept with a reusable user intellectual property core library. Furthermore, a soft-core processor and a real-time operating system are embedded into the same chip for realizing the control law to steer the Mobile Platform. Simulation results are conducted to show the effectiveness and merit of the proposed control method in comparison with a conventional proportional-integral feedback controller. The performance and applicability of the proposed embedded adaptive controller are exemplified by conducting several experiments on an autonomous omnidirectional Mobile robot.

A New Mobile Platform (RHyMo) for Smooth Movement on Rugged Terrain
IEEE ASME Transactions on Mechatronics, 2016Co-Authors: Dongkyu Choi, Youngsoo Kim, Seungmin Jung, Jongwon Kim, Hwa Soo KimAbstract:This paper suggests a new performance metric for a Mobile Platform called as a posture variation index (PVI) to evaluate the smoothness of its movement, which is an important factor to predict undesired oscillations or shocks on a Mobile Platform while traveling on rugged terrain. The PVI consists of the height and pitch angle variations of center of mass of a Mobile Platform. By using the PVI, the movements of well-known Mobile Platforms are systematically analyzed. In order to ensure smooth movement as well as high terrainability on rugged terrain, a new Mobile Platform (RHyMo) is constructed on the basis of the kinematic and quasi-static analyses. The extensive experiments are carried out by using the RHyMo and the Rocker–Bogie Platform on the artificial rugged terrain, which verify that in comparison with the Rocker–Bogie Platform, the average and maximum height variations of RHyMo are reduced by 12.72% and 5.96%, respectively. Moreover, the average and maximum pitch angle variations of RHyMo are significantly reduced by 65.87% and 60.53%, respectively. The terrainability of RHyMo against a high step and steep stairs is improved with the help of the track mechanism installed in the front linkage.
