Generating robot motion trajectories instantaneously in the moment unforeseen sensor events happen is very essential for many real-world robotapplications. Using a previous work on online trajectory generation as a basis, this paper proposes an alternative approach that also considers dynamic models. The former class of algorithms does not take into account dynamically changing acceleration capabilities based on maximum actuator forces/torques. This paper extends target velocity-based algorithms of the previous approach by taking into consideration the entire system dynamics when generating trajectories online within one control cycle (typically 1 ms or less). The extension includes the acceleration capabilities of a robot at every discrete time step assuming constant values for the maximum actuator forces/torques, thus allowing the generation of adaptive trajectory profiles during the motion of the robot. Several real-world experimental results using a seven-degree-of-freedom lightweight robot arm underline the relevance of this extension.

While people use more social network mobile games, research on SNMG is gaining more attention. This article presents results of entertainment and external drivers function in intention of social network mobile game and we suggest a research model that extend TAM model by adapting values from social network mobile game nature. Structural Equation Modeling (SEM) was used to measure relationships. We found that three factors, social norm, conditional value and perceived entertainment positively influence to intention. In conclusion, firms would use result of research to develop more favorable social network mobile game applications by reflecting values explored in this paper.

Of late natural and man made calamities became unmanageable. Notwithstanding the fact that Government takes all steps to protect and reduce the impact of calamity, Right from the ancient times only humans are being used for these rescue operations. However, over the past decade or so, the autonomous systems role has changed - the emergence of smart munitions and precision aerial bombardment has resulted in the human entering tough urban combat situations to mop up any remains of calamities. Our system is the first of several such programs that are looking at revamping the rescuers gear. Our system basically has two modes. One mode is the automatic mode and the other mode is user control mode. The automatic mode makes the robot to detect the obstacles and move without any human intervention using Fuzzy Logic. In certain unavoidable circumstances the control comes to user who can control the operations of the robot from remote location using a mobile phone. The user can control the robot by seeing the video through 3G technology. It also helps to provide medical aid for needy. Our system can also be used to detect and defuse the fire, human life detection during earth quakes. Thus our aim is to provide a robotic system that can act as a savior during natural and man made calamities.

A stereovision sensor system for depth measurement has been developed in our department. Stereo cameras attached to a robot can perform several tasks effectively, such as calculating distance of an object or that of a person by using depth map, which can further lead to achieve a bigger goal of grasping or manipulation of objects. We have calibrated the cameras and applied rectification algorithm to the images to develop the stereo pair. While taking the data we have observed that due to divergence of cameras, the calculated distances were larger than the actual distances. We concluded that a further improved system can be developed which can take care of this systematic error and achieve more accurate results.
