A new torso design of humanoid robot is proposed as a 3-DOF PKM (Parallel Kinematic Manipulator) structure by using results of a biomimetic analysis of torso in humans and animals. Main characteristics of torso in nature are presented from which design requirements are outlined for a solution in humanoid robot. The PKM torso is consist of two platforms and four UPU mechanisms. The usefulness of such a biomimetic inspiration is proved by a numerical simulation of the proposed PKM torso in its basic movements.

We consider the event-triggered state estimation of a finite-state hidden Markov model with a general stochastic event-triggering condition. Utilizing the change of probability measure approach and the event-triggered measurement information available to the estimator, analytical expressions for the conditional probability distributions of the states are obtained, based on which the minimum mean square error event-based state estimates are further calculated. We show that the results also cover the case of packet dropout, under a special parameterization of the event-triggering conditions. With the results on state estimation, a closed-form expression of the average sensor-to-estimator communication rate is also presented. The effectiveness of the proposed results is illustrated by a numerical example and comparative simulations.

This paper proposes a new method of linear inverted pendulum control, which is used to control the quadruped robot walking on regular uneven terrain such as ramp and stair, furthermore, this method can be applied to a more rugged terrain. This paper analyzes the dynamic parameters of a quadruped robot walking on the complex terrain, which means the supporting points of the robot lie in different heights relative to the level ground. In order to ensure the same leg length, there will be energy dissipation caused by the raise of the center of mass. Therefore this paper proposes a dual length linear inverted pendulum method (DLLIPM), which not only effectively reduces the energy dissipation, but also promotes the workspace utilization. In addition, Newton-Raphson algorithm is used to optimize the linear inverted pendulum movement, which makes the movement symmetrical and smooth. Finally this paper presents simulation results with DLLIPM on a quadruped robot with 16 degrees of freedom.

With the development of information technology, the increase of system information brings new problems to the military system effectiveness evaluation. Aiming at nonlinear, high dimension and strong coupling data of system effectiveness analysis, a data yard based system effectiveness evaluation and decision support method was proposed. Data recovery, subtraction, refinement and reconstruction operations were applied to the simulation data processing, then a data yard cube was built up to meet the multiple demands for system analysis of different levels and data dependency were reduced. Taking task-oriented networked fire control system for example, its system effectiveness evaluation, timeliness evaluation and indices analysis were carried out, and practicability and validity of the method were verified in three levels. Applying data mining technology to the simulation system effectiveness evaluation decision-making, makes it get more extensive application.

A novel method is presented to solve many problems of joints for space manipulator, such as large volume, large flexibility, complex routing and low system-control precision, which can realize integrated design for space manipulator joint with high-cohesion and low-coupling (HCLC) performance. Moreover, the mechanical and electrical interfaces of designed joint are especially suitable for space manipulator. First, To achieve higher system performance, the joint is designed as a whole for perfect match among components including permanent magnet synchronous motor (PMSM), motor controller and driver, sensors, space environment controller, reducer, routing and other mechanisms, which could eliminate redundant shell packages and mounting surfaces existed in traditional manipulator joint. Second, a new method is presented to design the rotors of two resolvers as joint sensors at the same axis shared with motor rotor, this kind of design has the advantages of redundant and high-precision sensing for the positions of motor rotor and joint, and joint position signal is differential sensing and has high robustness. Then, a kind of high-precision controller is presented for space manipulator based on a new PMSM model with model difference, and this controller is robust to joint nonlinear factors, such as friction and other disturbance torque. Finally, the experimental results showed the designed joint had fine performances with high power density, high controlling precision and high operation stability and so on, and it is suitable for the application of space manipulator. © Springer International Publishing Switzerland 2014.
