摘要： 当机器人仅依靠计算机视觉时，它只能勉强搜索周边的目标。卡耐基一梅隆大学机器人研究所的一名研究人员称，通过利用所有提供给它的信息，例如目标的位置、大小、形状、能否被移动，机器人能通过对目标的不断探索来逐步改善对目标的理解与认知。卡内基梅隆大学的研究人员建立了目标物体数字模型以及图像，然后将这些数据导入机器人管家（HERB）的记忆卡中，因此，机器人能够识别出所需要进行处理的对象。实际上，所有机器人方面的专家为了让他们的机器人能识别物体所做的操作都是类似的。

摘要： The article focuses on the important role played by industrial robots in the operation of the manufacturing industries. It highlights the initiative of several small and medium-sized companies to employ new generation robots to help them improve production output and compete in the global scale. It also notes that robots were not meant to take jobs from people, rather, they were designed to achieve greater quality and productivity and perform dangerous tasks.

摘要： We present the overall user experience designed for supporting rehabilitation of stroke patients at home. Patients use a robotic hand (orthosis) to control therapeutic games and a touch screen for the UI. They are supervised remotely by a therapist who uses a similar interface from their desk. The system includes therapeutic games and user interfaces (UIs) for both patients and therapists. The concept and design of these UIs were implemented during the first year of the SCRIPT project

摘要： A simulator intended to give robot makers a hand during a Defense Advanced Research Projects Agency contest is expected to remain an integral part of how developers design the machines in the future. DARPA is in the midst of its Robotics Challenge program, which is asking teams to use a humanoid robot to perform a series of complex disaster-response tasks. DARPA wanted to include as many entrants as possible, said Brian Gerkey, the CEO of the Open Source Robotics Foundation, a San Francisco Bay area nonprofit devoted to standardizing software in the industry.

摘要： Purpose: Robotics-assisted tilt table technology with integrated leg drives for basic stepping functionality is clinically available for patients with neurological impairments. Initially introduced for early rehabilitation, it provides cyclical stepping movement and physiological loading in immobilized patients. This technology provides stability and support in patients with neurological disorders for whom weakness, balance and coordination problems would preclude cardiopulmonary performance testing using a treadmill or cycle ergometer. This type of device may facilitate the estimation of peak oxygen uptake and other important cardiopulmonary performance parameters in patients who have neurological deficits. The aim of the present study was to assess the feasibility and safety of this device for peak cardiopulmonary performance testing in able-bodied ***: A robotics-assisted tilt table (Erigo, Hocoma AG, Switzerland) was augmented with force sensors in the thigh cuffs and a work rate estimation algorithm. A custom visual feedback system was employed to guide the subjects’ work rate and to provide real time feedback of actual work rate. Each subject carried out an incremental exercise test to the limit of functional capacity with a work rate increment of 5 W/minute in female subjects and 8 W/minute in males. Outcome measures were peak oxygen uptake (VO2peak), peak heart rate (HRpeak), respiratory exchange ratio (RER), peak work rate (WRpeak) and the Borg CR10 scale to measure exertion and leg ***: 11 able-bodied subjects were included (9 male, 2 female; age 29.6±7.1 years: mean ± SD). Resting VO2 was 4.6±0.7 ml/kg/min and VO2peak was 32.4±5.1 ml/kg/min. All participants reached at least 85% of their predicted HRmax value. RER at peak VO2 was 1.02±0.07. Eight participants (72.7%) reached their peak VO2 in 8-12 minutes, which is considered the optimal duration. The average WRpeak was 65.7 W for males and 41.5 W for females. All participants rep

摘要： In order to improve robot arm intelligent tracing control accuracy and make the robot move in the environment autonomously, the robot must be capable of calculating its pose, the nominal system dynamics model based on orientation parameters of moving plant of shoulder is developed. Pose localization problem is a key researching domain in the mobile robot community and get much attention around the world. This dissertation is focused on the multi-sensor fusion based pose calculation problem for mobile robot. Application results show that the intelligent tracking has a significant effect in improving the tracing efficiency and reducing the tracking and monitoring cost, improving the capability of environment perception, co-operating and autonomous navigation of mobile robot. © 2013 IFSA.
