The persistent localization of moving targets is one of the most important applications of mobile robot systems. However, the sensors on each individual robot are often not sufficiently accurate for this task, presenting a severe limitation on the application of robots to many situations. To overcome this problem, systems of multiple robots have been established. These systems improve the localization...
In the 2nd International Unmanned Aerial Vehicle (UAV) Innovation Grand Prix (UAVGP) sponsored by Aviation Industry Corporation of China (AVIC), an autonomous barrel transportation mission was proposed for Rotary-wing UAV (RUAV) which aims at validating the feasibility of marine vertical replenishment by RUAVs. The RUAV was supposed to track the movable platform, pick up barrels on the supplier platform,...
Brain-computer interface (BCI) is currently developed as an alternative technology with a potential to restore lost motor function in patients with neurological injuries. In this paper, we describe an integrated system of a non-invasive electroencephalogram (EEG)-based BCI with a non-invasive functional electrical stimulation (FES). This system enables the direct brain control of upper limbs to achieve...
A multifunctional myoelectric prosthetic hand is a perfect gift for an upper-limb amputee, however, the myoelectric control for a prosthetic hand is not so good now. Here, the paper presents a comparative study on electromyography (EMG) pattern recognition based on PCA and LDA for an anthropomorphic robotic hand. Four channels of surface EMG (sEMG) signals were recorded from the subject's forearm...
An experimental study of an active cooperative observation approach based on Extended Set-Membership Filter (ESMF) is completed. In the experiment, the two RFRs can keep the optimal observation formation while achieving the cooperative observation so that the observation accuracy is improved further. The most attracting advantages in this video is that the experimental results on the testbed showed...
A new laser scan matching algorithm is proposed in this paper. By constructing multiplex histograms, the new algorithm offers a simple way for importing geometrical features into the histogram method, obtaining more geometrical information from the laser scan data, and carrying out more accurate matching results. Also, an optimal maximum selection mechanism is employed to filter out the incorrect...
In this paper, a semi-decoupled state space model of a small-size helicopter is developed for hovering conditions in order to simplify the model identification process. An optimal estimation algorithm in frequency domain is proposed and implemented to estimate the parameters in the state space model using real flight data collected from a SERVOHELI-40 small-size unmanned helicopter. The accuracy of...
