An efficient path planning algorithm, for multi degrees of freedom manipulator robots in dynamic environments, is presented in this paper. The proposed method is based on a local planner and a boundary following method for rapid solution finding. The local planner is replaced by the boundary following method whenever the robot gets stuck in a local minimum. This method was limited to 2-DoF mobi...

We present an interactive algorithm to generate plausible trajectories and full-body crowd simulations. Our formulation is based on a novel two-way coupling between 2D multi-agent collision avoidance and high-DOF human motion synthesis. We present a collision-free navigation algorithm that takes into account human motion and biomechanics constraints to compute smooth trajectories. Furthermore, ...

Based on the square heat-generation body (HGB) with “arrow-shaped” high-thermal-conductivity channel (HTCC) model established in previous literature, we performed multi-objective optimization (MOO) maximum temperature difference (MTD) minimization and entropy-generation rate (EGR) as objectives for its performance. Pareto frontiers optimal set were obtained based NSGA-II. TOPSIS, LINMAP, Shanno...

In naval engineering and related disciplines, it is common for dynamic models of the human body to be used in conjunction with quantitative records of body and ship motions, in order to study human balance behaviour while performing various shipboard activities. Research in this area can lead to improvements in ship operations and designs that improve crew safety and efficiency. This paper pres...

A half-car model with four DOF was established to simulate the system. On the basis of this model, Selfadapt Parameters Fuzzy-PID control method of the active suspension system is described. In such a model, vehicle speed, vehicle body vertical acceleration, suspension dynamic deflection, the body vertical acceleration and suspension dynamic deflection integrated feedback were used respectively...

Abstract: This paper presents the modeling and multivariable feedback control of a novel highprecision multi-dimensional positioning stage. This integrated 6-degree-of-freedom (DOF) motion stage is levitated by three aerostatic bearings and actuated by 3 three-phase synchronous permanent-magnet planar motors (SPMPMs). It can generate all 6-DOF motions with only a single moving part. With the DQ...

The authors have focused on the bipedal humanoid robot expected to play an active role in human living space, through studies on an anthropomorphic biped walking robot. As the first stage of developing a bipedal humanoid robot, the authors developed the human-size 35 active DOF bipedal humanoid robot “WABIAN” and the human-size 41 active DOF bipedal humanoid robot “ WABIAN-R”. The authors also ...

Vertical displacement acceleration and the pitch angle record produce phenomenon of beat vibration when testing a 200 m electro-dynamic suspension (EDS) magnetic levitation (maglev) test vehicle with high-temperature superconducting (HTS) at CRRC Changchun Railway Vehicles Co., Ltd., where is clamped in planar motion. First, to examine this phenomenon, paper establishes dynamic equations three ...
