  • Planning to learn: Integrating model learning into a trajectory planner for mobile robots

    Publication Year: 2009, Page(s):18 - 23
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (151 KB) | HTML iconHTML

    For a mobile robot that performs online model learning, the learning rate is a function of the robot's trajectory. The tracking errors that arise when the robot executes a motion plan depend on how well the robot has learned its own model. Therefore a planner that seeks to minimize collisions with obstacles will choose plans that decrease modeling errors if it can predict the learning rate for eac... View full abstract»

  • Adaptive distance function and its application in free-form surface localization

    Publication Year: 2009, Page(s):24 - 28
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (689 KB) | HTML iconHTML

    Localization plays an important role in design and manufacturing of free-form surface products. Conventional iterative methods can supply an accurate result for localization, but they usually require a good initial estimate of rigid transformation. For the objects with high-curvature features, they suffer from poor accuracy or slow convergent speed. In this paper, a new distance function is define... View full abstract»

    This paper deals with the stabilization problem for discrete-time nonlinear systems that are represented by the Takagi - Sugeno fuzzy model. By the multiple fuzzy Lyapunov function and the three-index algebraic combination technique, a new stabilization condition is developed. The condition is expressed in the form of linear matrix inequalities (LMIs) and proved to be less conservative than existi... View full abstract»

    The mathematical model of the Permanent Magnet Linear Synchronous Motor (PMLSM) direct drive system is deduced in this paper. A fuzzy PID controller is designed by combined fuzzy control with conventional PID control. Simulated and experimental results show that the fuzzy PID controller is superior to the conventional PID controller in dynamic steady performance, and the fuzzy PID controller has s...

    When the initial state of the stable gaits does not match the structure parameter values, the robot may fall down. To estimate a initial state of the stable gaits for the biped robot with knees, a new numerical method is proposed in this paper. It is based on the theories of cell mapping and Poincareacute return map. This numerical method has general applicability. We can use this method to estima... View full abstract»

    A significant amelioration of our previous work is presented aiming at building autonomously visual models of unknown objects, with a humanoid robot. Previously we introduced a Next-Best-View solution using two stages: (i) an optimization algorithm without derivatives finds a camera pose maximizing the amount of unknown data visible, and (ii) a whole robot posture is generated with a different opt...

    When a humanoid robot moves in an actual working environment, it is necessary for the robot to generate appropriate locomotion trajectory in real-time to ensure its stability. But it is difficult to solve nonlinear differential equations of stability constraints in real-time to get stable locomotion trajectory. This paper proposed a method to generate stable and smooth locomotion trajectory throug... View full abstract»

    The growing size of the multiprocessor systems increases their vulnerability to component failures. It is crucial to locate and to replace the fault processors to maintain system's high reliability. The fault diagnosis is the process of identifying fault processors in a system through testing. The conditional diagnosis requires that for each processor in a system, all the processors that are direc... View full abstract»

    Interval multicast was defined as to send a message to a subset of a group, rather than all of the members in the group, which is important in battle fields and other applications. A key-tree based approach was proposed to achieve interval-multicast security, i.e., to securely multicast the message to the subgroup. The cost of the proposed approach is defined as the number of different keys needed... View full abstract»
