BACKGROUND AND PURPOSE Cost in healthcare is an increasing and justifiable concern that impacts decisions about the introduction of new devices such as the da Vinci(®) surgical robot. Because equipment expenses represent only a portion of overall medical costs, we set out to make more specific cost comparisons between open and robot-assisted laparoscopic surgery. MATERIALS AND METHODS We perf...

How to improve the performance of a simulated soccer team using final game statistics? This is the question this research aims to answer using modelbased collaborative techniques and a robotic team – FC Portugal – as a case study. After developing a framework capable of automatically calculating the final game statistics through the RoboCup log files, a feature selection algorithm was used to s...

dimensional synthesis of a parallel robot may be the initial stage of its design process, which is usually carried out based on a required workspace. since optimization of the links lengths of the robot for the workspace is usually done, the workspace computation process must be run numerous times. hence, importance of the efficiency of the algorithm and the cpu time of the workspace computatio...

Human-Robot Interaction requires coordination strategies that allow human and artificial agencies to interpret and interleave their actions. In this paper we consider the potential of artificial emotions to serve as coordination devices in human-robot teams. We propose an approach for modelling action selection based on artificial emotions and signalling a robot’s internal state to human team m...

based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. in this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. the state space representatio...

This paper presents a human-robot interface system that enables a user to move a robot by moving his hand. It adopts the technique of the 3D measurement based on the affine invariants from multiple views. In this system, we can choose a reference frame to obtain the 3D hand motion between the user-centered frame and the world-fixed frame. With the former frame, the system interprets the user's ...

The Learning Robot Laboratory at CMU recently started distributing real-world data collected from it's mobile robot. The goal of this action is twofold ; to make robot data available to researchers without access to a mobile robot and to encourage cross comparison of diierent methods by running them on the same data. We present a description of our robot and the type of data it provides. We bri...

In this study, a manipulator calibration algorithm is suggested to decrease the positional errors of an industrial robotic using genetic select optimal measurement poses. First, based on observability index used for selection By employing selected poses, conventional kinematic identify geometric robot. Finally, further improve accuracy robot, compliance are compensated by radial basis function ...

Generally speaking, the mobile robot is capable of sensing its surrounding environment, interpreting the sensed information to obtain the knowledge of its location and the environment, planning a real-time trajectory to reach the object. In this process, the issue of obstacle avoidance is a fundamental topic to be challenged. Thus, an adaptive path-planning control scheme is designed without de...
