Lie group symmetry in a mechanical system can lead to a dimensional reduction in its dynamical equations. Typically, the symmetries that one exploits are intrinsic to the mechanical system at hand, e.g. invariance of the system's Lagrangian to some group of motions. In the present work we consider symmetries that arise from an extrinsic control task, rather than the intrinsic structure of configuration space, constraints, or system dynamics. We illustrate this technique with several examples. In the examples, the reduction enables us to design essentially global feedback controllers on the reduced systems.We apply task-induced symmetry and reduction to a recently developed 6 DOF kinematic model of steerable bevel-tip needles. The resulting controllers cause the needle tip to track a subspace of its configuration space. We envision that the methodology presented in this paper will form the basis for a new planning and control framework for needle steering.

A new, energy-based method is proposed for guaranteeing the stability of large classes of control systems with minimum performance losses. Based on a network presentation, the large classes of control systems are analyzed in a unified framework. In this unified network model, the concept of passivity is used to study the stability of large classes of control systems. For guaranteeing the stability condition, the time-domain passivity controller is extended to a 2-port network to make the controller 2-port passive. The developed method is tested with numerical simulation in the regulation of a single link flexible manipulator. Totally stable control is achieved under a wide variety of operating conditions and uncertainties without any model information.

This paper proposes a novel energy-based control law for biped robots based on an analysis of passive dynamic walking. Firstly we discuss the essence of dynamic walking using a passive walker on a gentle slope. In the second, we propose a simple and effective control law which imitates the energy behavior in every cycle considering the ZMP condition and other factors of the active walker. The control strategy is formed by the feature of mechanical energy dissipation and restoration. By the effect of the proposed method, the robot can exhibit natural and reasonable walk on a level ground without any gait design in advance. The validity of the proposed method is examined by numerical simulations and experiments.

We propose here a new type of leg rehabilitation system. The aim of the system is to realize the multiple-degree-of-freedom (DOF) training of a leg by manipulating the patient's leg with wires. First, a single-DOF experimental system was built and tested, and the experimental results showed the feasibility of a wire-driven leg rehabilitation system. Next, a 2-DOF experimental system was designed, with a target motion of flexion/extension of both the hip and knee joints. Experiments of single-DOF motion on a test dummy and a male subject showed that the system generated enough accurate motion to support a range of motion exercises. In addition, the results demonstrate that the wire-driven mechanism is user friendly.

An attractive self-organizing fuzzy system (SOFS) with on-line learning ability is proposed in this paper The SOFS possesses the ability of self-organization and on-line learning for its knowledge base in application while the plant is viewed as a "black box" for the SOFS. A novel concept of pseudo-errors is utilized to capture the characteristic of plant behavior, and the information of pseudo-errors is considered as the behavior information of a plant. With statistical regression, observed data pairs of pseudo-errors are collected and analyzed input space formed by pseudo-errors is partitioned into several regions in cluster form. In cluster-based fuzzy reasoning, the partitioned region in the input space is viewed as the antecedent of a fuzzy if-then rule, in which Gaussian membership functions are used. Based on random optimization algorithm, an on-line learning method is proposed in the paper. It enables the SOFS to learn on tracking a reference curve directly. The learning iteration is divided into several sub-parts to make the on-line learning feasible by which the system parameters are. updated in a real-time style to search for the optimal fuzzy sets of if-then rules. The T-S fuzzy model is utilized, where the consequent parts are in the form of linear function. Inferred result does not require defuzzification because the consequents of the fuzzy rules are crisp. Motion control of an auto-warehousing crane system is used to illustrate the feasibility of the proposed approach.

A new approach to the design of a fuzzy continuous gain scheduled H/sub /spl infin// controller based on Taylor series fitting for n-joint rigid robotic manipulators, which guarantees satisfactory dynamic characteristics in the whole movement range, is presented. This scheme combines the gain scheduled H/sub /spl infin// theory with LMI approach to design a continuous gain scheduled H/sub /spl infin// controller, which is applicable to systems with fast state variations so that the deficiency of the conventional gain scheduled controllers is overcome, with the use of Taylor series fitting. Fuzzy control is then incorporated so chat the designed controller possesses the characteristics of a fast response for large errors and a well-damped response for small errors. The system thus always has a good dynamic performance along with the variations of the system states. Simulations and experiments demonstrate the effectiveness of the designed controller.

An area-covering operation is a kind of complete coverage path planning, which requires the robot path to cover every part of the workspace, which is an essential issue in cleaning robots and many other robotic applications such as vacuum, robots, painter robots, land mine detectors, lawn mowers, and windows cleaners. In this paper, a novel biologically inspired neural network approach is proposed for complete coverage path planning with obstacle avoidance of a cleaning robot in a nonstationary environment. The dynamics of each neuron in the topologically organized neural network is characterized by a shunting equation or an additive equation derived from Hodgkin and Huxley's (1952) membrane equation. There are only local lateral connections among neurons. Thus the computational complexity linearly depends on the neural network size. The proposed model algorithm is computationally efficient, and can also deal with changing environment. Simulation results show that the proposed model is capable of planning collision-free complete coverage robot path.

Electromyogram (EMG) has often been used as a control signal for a prosthetic arm, which includes information on the operator's motor intentions and the mechanical impedance of joints. Most previous research adopted the control methods of the prosthetic arms based on the EMG pattern discrimination and/or the force estimation from the EMG signals, and did not utilize any knowledge on tasks performed by amputees such as object grasping and soup-spooning tasks. In this paper, a new myoelectric control method is proposed using a statistically organized neural network and an event-driven task model. The task model is represented using a Petri net to describe the task dependent knowledge, which is used to modify the neural network's output. Experimental results show that the use of the task model significantly improves the accuracy of the EMG pattern discrimination.

The problem of real-time pose estimation of moving objects using a stereo video camera system is considered in this paper. A computationally efficient algorithm is proposed based on Kalman filtering of the position measurements of suitable feature points selected on the target objects. The efficiency of the algorithm is improved by adopting a new pre-selection technique of the feature points, based on binary space partition (BSP) trees, which takes advantage of the Kalman filter prediction capability. Computer simulations are presented.

We have developed a laser scanner based simultaneous localization and map building method, specifically addressing the divergence problem of the classical extended Kalman filters (EKF) based simultaneous localization and map building (SLAM) algorithms. Our method utilizes two EKFs. The first is used to estimate the orientations of the robot and the obstacles, and the second estimates the positions of the robot and of the obstacles. Experimental results are also presented to verify our arguments.
