This article describes a prototype microfluidic system for insulin detection and exchanging the results digitally with physicians located off-site. The integrated polydimethysiloxane (PDMS) microfluidic system uses two pneumatic micropumps and one micromixer for chemiluminescent immunoassay, and a developed communications infrastructure for transferring the digital information from the assay site to a remote place for assistance by a trained medical professional. The expert can then directly provide control and diagnosis via the Internet. The insulin detection protocol is based on coupling the highly specific double-antibody sandwich immunoassay with the sensitive chemiluminescence of Luminol-Hydrogen Peroxide (H2O2). The peak value of the luminous intensity, recorded automatically by a photometer, is used as an indicator for the insulin concentration of the sample tested. The calibration curves of the insulin measurement were quantified and the insulin detection limit meets the common requirement of current clinical studies of diabetes. The combination of PDMS microfluidic devices and a communication strategy for exchanging information obtained from the assays with off-site diagnosticians offers new opportunities for point-of-care type health monitoring, especially in rural areas where patients must travel great distances to physicians to obtain diagnostic information that might be obtained more cost effectively by local, less-trained personnel. © 2011 IEEE.

In this paper, a simple and straightforward visual graphic approach for mobility and singularity analysis of mechanisms is introduced. Although the proposed method is established upon the reciprocal screw system theory, it needs no formula derivation instead knowing about a few simple rules. As a study case, mobility and singularity analysis for a class of two degrees-of-freedom (DOF) rotational parallel mechanisms i.e. well-know Omni-Wrist III with four limbs, and its two derived architectures with three limbs (named T-type and δ-type) is analyzed by the proposed method. As a result, a novel PKM derived from Omni-Wrist III is presented, which has the DOF and kinematics property close to Omni Wrist III. Copyright © 2011 by ASME.

Amphibious snake-like robots are advantageous than traditional snake-like robots for their adaptability in aquatic environments. This paper presents a novel amphibious snake-like robot. The mechanism and control system of the robot are illustrated. A simplified Serpenoid Curve is used to generate the basic undulation of the robot. Three-dimensional gaits are generated by combining undulations of the robot on the horizontal and vertical planes. Novel gaits are found, including a S-shape rolling gait on the ground and a diving gait in the water. Experiments have been done to validate the gaits and show the performances of the gaits under different control parameters.

Aiming at the problems of vibration on hydraulic pipe in aircraft, using math modeling and simulation is a quite efficient and effective method in theory. In this paper, the 14-equation Fluid-Structure Interaction (FSI) with influence of viscous friction is established for modeling the pipe and fluid. By using the Transfer Matrix Method (TMM), the components and pipelines are connected to get the simulation results of resonance frequency points and dynamic impedance of system. Our simulation demonstrates that most of the flow fluctuation between the natural frequencies of pump is absorbed by bumper;the vibration of high-frequency is damped if the filter is set in front of the pipeline system, and the vibration-absorbing effect of hose is better than pipe or hose-pipe-hose followed the pump. © 2011 IEEE.

Motion targets tracking techniques is one of the most important aspects in the fields of mobile robot research under unknown environments. To solve the problem of unstable vision resulted from the uncertainties, a method of active compensation for robot visual was proposed based on the principle of bionic eye movements. According to oculomotor neural circuits, an adaptive oculomotor control model of eye movements was established, and the model includes that VOR, smooth purisuit and compound eye movements. In order to verify the model's performance, some simulation experiments ware conducted in different environment. Simulation results show that the model can be active compensation of visual error caused by the dynamic variation of the robot attitude and the tracking target location. Finally, physical robot experiments results also confirm the effectiveness of the control model. Compared with the conventional camera, this new one can solve the problem of unstable vision. © 2011 ACADEMY PUBLISHER.

Predicting Torque by using Electromyography (EMG) signals is a significant problem as long as wearable robots is concerned. In this paper, a coarse-to-fine algorithm, named as Hierarchical Projected Regression, is proposed to estimate the torque of elbow by the surface EMG signals from human's arm. HPR is learned based on a clinical dataset. First, the real torque distribution can be clustered by k-means algorithm. Meanwhile, the EMG signals are divided into multi-clusters corresponding to the partitions of torque dataset. Then, a projected matrix is derived based on the criterion of Linear Discriminant Analysis, by which the low dimensional features are extracted from the original high dimensional EMG. Finally, the process extends to multi-level tree algorithm based on the hierarchical variance reduction of individual torque cluster. The experimental results show the high accuracy and efficiency of this novel method. © 2011 IEEE.

Attitude Control for an underwater vehicle working in shallow wavy water is an important capability. In shallow water this mission most likely will be disturbed by the large surge induced hydrodynamic forces acting on the underwater vehicle. In this paper, the second order wave drift force affecting severely the underwater vehicle in shallow water are presented. On the basis of wave force analysis, three dimension disturbances caused by wavy surgy water are measured and a control system using least squares multi-order data fitting polynomial prediction and fuzzy compensation combined with PID controller is put forward. The experimental results show that the control system for disturbance of surge and wave is feasible and effective.

This paper presents an attachment module for mini wall-climbing robot based on sine vibrating suction method. The basic idea of this method is that the vacuum can be generated inside a suction cup attaching on a surface, if a periodically vibrating force directly drives the suction cup. In this paper, mathematical model of sine vibrating suction method based on Bernoulli's equation is built. It is found that the vacuum degree in the suction cup is mainly determined by two parameters, namely the amplitude and frequency. To verify the correctness of the analyses, an experimental platform was developed. The results indicate that the vibrating suction method can definitely produce continuous vacuum. According to the experiment result, an attachment module for wall-climbing robot was developed. Moreover, the validity was verified by a series of suction experiments on different wall. Finally, the feasibility of the attachment module was basically testified on a caterpillar wall-climbing robot. © 2011 Published by Elsevier Ltd.

Biological fish propelled by wide paired pectoral foils is attractive for the special characteristics as their nature samples. Advantages and limitations of two groups of the bionic flatten pectoral foils classified by actuation arrangement are summarized. Key flapping properties of cow-nosed ray affecting its driving performance are obtained. Simplified driving method and typical theoretical postures for the designed bionic wide pectoral foil is analyzed and verified through experiments. A bionic fish based on this kind of foil has been developed and tested in air and water. Various postures designed imitating cow-nosed ray in air have also been verified. Furthermore, the swimming performance tests in water show that the bionic fish can achieve maximum forward swim speed of 0.7 times of body length per second and an excellent turning maneuverability with a small radius.

One of the prerequisites for AFM based nanomanipulation is that the position of the target nanoparticle can be stable controlled within a known area, while this prerequisite is still hindered by the uncertainties including the initial position of the nanoparticle and of the AFM tip, together with the uncertain forces from the substrate and so on. In this paper, a Stochastic Pushing (SP) model and a Stable Pushing Strategy are proposed respectively, which can push the nanoparticle into a bounded target area within a given probability. Simulations and experiment based on the proposed SP model demonstrate the validity of the Stable Pushing Strategy. © 2011 IEEE.
