This paper reports a new design of a three-dimensional vibration energy harvester with high energy output and low working frequency. In a three-dimensional vibrating environment, this electromagnet harvesting structure will have voltage outputs from any directions under a low driving frequency. The volume is about 30mm*30mm*27mm. For an excitation acceleration of 1g, the peak voltage and power output of the electromagnetic part under the vertical vibration can reach to 1.3 V and 0.31mW/cm3, respectively. When the excitation comes from horizontal direction, the peak voltage and power output of electromagnetic part can reach to 361 mV and 0.88mW at 30 Hz. The maximum output of triboelectric part under the vertical vibration can reach to 20V and 17.32μW/cm2 at the excitation frequency of 35 Hz.

In this work, we studied on the mechanical behavior of RB-SiC by the indentation experiments. The Vickers hardness tester and the laser scanning confocal microscope are used to process and observe the RB-SiC sample pieces. The indentations result shows that the hardness at the Si phase is lower than the Si C phase, thus it is easier to remove the Si than SiC. The morphology of indentations are complicated, there were no accumulation phenomenon at indentation edge. When the loading was 0.1 kgf, 0.2 kgf and 0.3 kgf, only the radical cracking can be observed and the cracking was not obvious at Si and Si C mixed phase. Avalanche crushed phenomenon occurred when the load increased to 0.4 kgf. According to the Evans' fracture toughness formula, the fracture toughness of Si C phase is about 2.5 MPa?m1/2, and the fracture toughness of Si-SiC mixed phase is bigger than 3.0 MPa?m. The critical cutting depth（dc） of RB-SiC was calculated by empirical formula presented by T. G. Bifano, and the value is 22.54 nm.

This paper presents different micro-manipulation strategies on various micro-spheres and adaptive end-effectors. Adjustable multi-gripper platform was designed to carry out these strategies. Among these strategies, two kinds of mechanical clamping methods were established based on double-gripper. Three kinds of micro spheres were picked up in the experiments with adhesive force strategies. Triple-finger gripper was used to verify the clamping and releasing strategy. The end-effectors such as tungsten probes, fibers and AFM probes had been used. Spheres with diameters of 20 μm, 60 μm, 80 μm and 800 μm were used to verify these composite strategies. The materials of spheres are silica, iron and boron silicate. The results show that this design of strategies is closely adapted to the manipulation tools, end-effectors and vision systems. © 2016 IEEE.

Nowadays autonomous welding robots are gaining importance. Weld seam detection is a key technology in robotic welding which is usually performed using a visual system. In most existing vision-based approaches, traditional image processings are used to obtain weld seams. Generally, these approaches are sensitive to their surrounding environment, especially illumination. Therefore, we address the problem by introducing the visual attention mechanism of the primate. Firstly, image preprocessing is executed to block visual interferences. Secondly, a visual saliency model based on local contrast is proposed to emphasize weld seam candidates. Finally, some basic image processings are performed to extract the desired weld seam. In order to validate the proposed approach, experiments are carried out in different cases: two types of joints (butt and fillet joint) and three types of shapes (straight line, zigzag and curve). The results demonstrate that this method is effective and robust, and is useful for autonomous welding robots. © 2016 IEEE.

Based on the requirement of complicated surface polishing from manufacturing automation, aiming at solving the complex and inefficient online teaching of robotic polishing system, this paper proposes a force-controlled polishing system and implements off-line programming on process path of blade polishing by robot through analyzing the deformation of the contact part between blade and buffing wheel. Finite element was used to analyze the contact part, and the blade polishing module was developed in the environment of robot studio combining the horizontal line cutting method and the Douglas-Peucker algorithm. Simulation was taken on the off-line module and the resulting file was input into the industrial robot to carry out experiments. The results show that this method had better experimental effect and faster processing efficiency. © 2016 IEEE.

This paper presents a flexible capacitive sensor array which can be attached on robot arm for tactile force measurement. We designed and fabricated three types of sensor array in different dimensions. The sensor array with 4×4 tactile units is made of copper and PDMS based on PET substrate. The static characteristics are performed and it is found that the sensor array with 3×3 mm2 unit size is the optimal one among these three types. The sensitivity of the optimal sensing unit is 0.84%/N in a force range of 0-3.7 N. In order to achieve the controlling of robot motion, we developed a capacitance detection circuit to transfer the capacitance change to voltage variation. Furthermore, a tactile feedback and signal acquisition system is built up for the application of robotic obstacle avoidance. © 2016 IEEE.

This paper presented a method of growing metallic nanowires by using electron beam technology under scanning electron microscopy (SEM). The metallic nanoparticles were dispersed evenly on Indium-Tin Oxide (ITO) by the spin coater. The ITO sample was experimentally prepared by the spin coating technique. The electron beam was focused on a metallic nano particle inside SEM, which were dispersed on the ITO. The growth of metallic nanowires was controlled by the movement of the electron beam. The method this paper presented can be employed for different kinds of metallic and can be used to fabricate metallic nanowires with different length. © 2016 IEEE.

Wind energy is a kind of inexhaustible renewable clean energy. Wind energy harvesting becomes a potential technique to solve the power supply problem of wireless sensor nodes in field environment. This paper demonstrates a hybrid flapping-leaf microgenerator (FLMG) that convert wind flow energy to electric energy. Both the piezoelectric and triboelectric parts will generate power from wind flow. The output performance can be improved by optimizing the size of the flapping leaf and the connecting position between the cantilever and leaf. At a wind speed of 4.5 m/s, the maximum power of the piezoelectric and triboelectric parts of one-side FLMG can be obtained as 8.1 pW and 13.6 pW at optimized load resistances of 1 MQ and 0.75 M?, respectively.
