The technology of lower limb rehabilitation robot is a hot research topic in recent years, while the exoskeleton robot is a typical representative. Accurate trajectory tracking ability is the base of the exoskeleton mechanical leg to coordinately drive trainers to do rehabilitation training on the treadmill. In this paper, aiming at the existing exoskeleton body, taking into account the uncertain...
Overall considering the existing elderly-assistant and walking-assistant robot has some drawbacks, such as single function and unnatural human-computer interaction, imperfect safety, a new type elderly-assistant and walking-assistant robot is developed, which has reliable assistance, preventing fall, multifunctional and natural transformation between functions. Based on introducing the structure of...
With the rapid development of elderly-assistant & walking-assistant robot. How to improve the intelligent level of elderly-assistant & walking-assistant robot has become a research focus in recent years. In order to improve the control accuracy of movement-mode of elderly-assistant & walking-assistant robot and meet the user's requirements for robot control. In this paper, a fuzzy control...
The intelligent Elderly-assistant & Walking-assistant equipment known currently has some problems widely. For example, the function of robot is signal; the human-computer interaction is not natural; the security is not perfect, and so on. In this paper, a multifunctional elderly-assistant & walking-assistant robot (EWR) is investigated, which can communicate naturally with users through the...
As a result of impairments, a majority of stroke or spinal cord injury (SCI) patients have significant functional limitations during recovery, including the inability to walk. Evidences demonstrate that patients can regain the ability to walk through lower limb rehabilitation. Over the last two decades, there has been growing development of robotic devices to assist the rehabilitation of ambulation...
Robotic devices for functional therapy for paralysis caused by neurologic injury is becoming popular now days. Effective control strategy is a key technical problem in developing a rehabilitation robot. In this paper, different control strategies for different training stages are proposed. Firstly, the rehabilitation process is divided into two stages which corresponding to two kinds of training modes:...
To improve the efficiency of the lower limbs rehabilitation robot in the rehabilitation training for stroke patients, a human-computer interaction model based on sEMG signals is presented. First, joint torque is got by decoding the sEMG signals according to Hill model, and the model's parameters are optimized using simulated annealing algorithm. Second, an assist coefficient is defined, and the lower...
The restoration of walking capability is very important after central nervous system (CNS) injury. Rehabilitation training robot can replace therapists to help patients do walking training by accurately simulating the human lower limb movement, and achieve the purpose of rehabilitation ultimately. In order to further improve the rehabilitation robots' intelligent and rehabilitation training effect...
In this paper, according to the old people's physical characteristics and their technical requirements for comfort and mastery when operating the robot, a detection and recognition method of tactile and slip senses is proposed that used to control the Elderly-assistant & Walking-assistant Robot. First, on the basis of the proposed drive control system program of tactile and slip, detection system...
This paper introduces a design of PC system for mobile robot based on ARM9. The hardware platform is S3C2440 from Samsung company as processor core, expanding 256MB Nand Flash, 2MB Nor Flash, 64MB SDRAM, etc. The software platform is embedded Linux operating system, and the design of the interface and the function of the system is based on Qt/Embedded of Linux. The software and hardware of the system...
This paper researches tankers risk issues by detentions and deficiencies database of port state control in Europe and the North Atlantic region, Asia and Pacific region, a comparative analysis of tanker risks with other types of ship was carried out and also the risks on oil tankers, chemical tankers and liquefied gas carriers were studied, it was found that the risks of tankers by Port State Control...
Exoskeleton Robot is a robotic-assisted human-machine system, which can provide power to assist the movement of people. This paper aims to find a method of EMG pattern recognition used in Exoskeleton Robot. To the beginning, the EMG power spectrum ratio (PSR) is calculated as the EMG eigenvalue. Then the minimum error-based Bayes decision rule is used to determine the movement intention of human,...
