Most of the upper limb exoskeletons proposed in the literature are designed for rehabilitation, however, there are few developments for activities assistance of daily living. This paper presents a wearable upper limb exoskeleton for activities assistance of daily living with the feature of mobility. It provides five degrees-of-freedom (DOF) for each arm, where 3 DOF and 2 DOF are given to the shoulder...
Cognitive radio (CR) techniques promise to significantly increase the available spectrum thus wireless bandwidth. With the increase of spectrum allowed for CR, it is critical and challenging to perform efficient wideband sensing. We propose an integrated sequential wideband sensing framework which concurrently exploits sequential detection and compressed sensing (CS) techniques for more accurate and...
Auto-parallelization compilization is an essential way to obtain high efficient parallel code for High Performance Computers (HPCs) and Chip Multi-Processors (CMPs). For the parallelizing compilers, a fundamental step is array dependence analysis used for identifying the parallelizable code. Whereas, the existing dependence analysis approaches are only capable of recognizing few types of dependences,...
A turning movement model structures for biped robot is present in this paper. An inverted pendulum model is introduced into robot's movement to achieve at the consumption problem when it turns. The relation between robots' Movement pattern and consumption is replied by the derived formula. Finally, simulation and experiment are achieved to prove the validity of the pattern proposed in this paper.
Water strider is an amazing insect that can effortlessly float, quickly run and jump on a water surface without drowning. It's of great challenge and interest to design and fabricates a micro robot that can walk on a water surface like water strider to carry out aquatic tasks such as water quality monitoring, aquatic exploration, water search and rescue. In this study, we designed a new type of biologically...
A teleoperation system of Internet-based Multi-Operator Multi-Mobile-Manipulator is proposed in this paper. The system consists of master sides and slave side, which has the characteristics of mobility, cooperation, distribution, fault tolerance, redundancy etc.. In master sides, with the aid of Distributed Virtual Environment and multi-video image, operators use the haptic interface device to control...
To illustrate value of Project Information Portal (PIP) to construction projects, this paper focused on a case study on Jean Workshop Project of Cone Denim on which Buzzsaw is applied. PIP application functions, implementation key points and meanings were discussed in detail by combining special situation analysis on this case project. Conclusion is given that PIP is adding value to project at all...
A reliable and efficient multi-robot coordination strategy is proposed to accomplish area exploration task in unknown environment. This approach is an improved one based on social potential field (SPF) model and market-based (MD) approach to coordinate the movement of multiple robots. Unlike traditional SPF, our model is a non-continuous one in time. In this approach, non-continuous SPF and market-driven...
Elman neural network was one of the dynamic recurrent neural networks. In this paper, a new modified Elman network was proposed first. Then the dynamic characteristics of Elman series neural network are fully discussed. The theory study proved that the new Elman network inherently has proportional (P), integral (I), derivative (D) properties and traditional Elman networks only have PI or I characteristics...
