Barrier coverage, which guarantees that every movement crossing a barrier of sensors will be detected, is known to be an appropriate model of coverage for moving detection and boundary guard. The related problems about barrier coverage with stationary sensors are extensively studied. When sensors are randomly deployed, we require much more sensors to achieve barrier coverage than deterministic deployment...
We propose a novel self-assisted rehabilitation system based on virtual reality, which is fit for the rehabilitation of mild stroke patients' upper limbs. The system consists of two haptic devices (PHANTOM Omni), an advanced inertial sensor (MTx) and a computer. With the inertial sensor, we can get the accurate orientation of one of the manipulator's hands in real time. At the same time, the haptic...
Swarm robotics is one of the important research directions of multi-robot systems, whose major feature is that the system includes many robots. How to control swarm-robot system is a challenging problem. Grid distribution means that a lot of robots distribute averagely in an area when they are demanded. We analyses a principle and method that based on artificial physics, we also put forward some performance...
Robotic therapy has been shown to increase the range of motion, strength, and agility of arm movements in chronic stroke patients, and many researches in this field have been carried out. In this paper, we are proposing a new approach of active rehabilitation for upper limbs. We suppose one of the subject's hands is intact, the other one is injured, and the intact hand can direct the mechanical assistance...
