In this paper, the stiffness of 3-DOF (Degree of Freedom) spherical joint robot based on cable-driven humanoid arm is analyzed. By utilizing forward kinematics, the pose of the robot is realized. then withthe analysis of static, the torque balance relationship between cables is realized. On the basis of the analysis of pose and cable tension, the stiffness of 3-DOF spherical joint robot can be analyzed, which mainly includes two parts: the stiffness related to structural parameters and the stiffness related to cable tension. Finally, by utilizing software ADAMS, the numerical simulate is proposed. It concludes that: the stiffness of 3-DOF spherical joint robot is related to the robot pose, cable stiffness and cable tension. When the cable stiffness is low, by changing inner cable tension, it will change the stiffness of the robot. the research results will provide theoretical guidance to tension and stiffness control for robot.

As robots become more pervasive in society, people will find themselves actively interacting with robots, and also rushing past them without any explicit interaction. People are able to maneuver in crowded situations by speeding up or slowing down to slip in between open pockets where people are not standing or walking. Our research focuses on this indirect bystander interaction. Scholtz defines a bystander as a person who "does not explicitly interact with a robot but needs some model of robot behavior to understand the consequences of the robot's actions" and does not have formal training about the robot [1], [2]. We investigated the level of trust that a bystander has of a robotic system in a corridor passing scenario by asking people to watch short videos of such scenarios where the hallway is only wide enough to accommodate two entities (either human or robot). Our goal was to understand the bystander's mental model of how a robot should behave when passing a human, the bystander's expectation of the robot to adhere to social protocol, and the overall trust a bystander has of the robot to do the right thing.

this paper presents a comparison of Stop & Go control algorithms, which deal with car following scenarios in urban environments. Since many vehicle/road interaction factors (road slope, aerodynamic forces) and actuator dynamics are very poorly known, two robust control strategies are proposed: an intelligent PID controller and a fuzzy controller. Both model-free techniques will be implemented and compared in simulation to show their suitability for demanding scenarios.

this study examined the interactions between children and robots by observing whether children help a robot complete a task under five conditions to determine which elicited the most help. Each condition had an experimental and control group, with 20-32 children (even number of boys and girls) in each group. Visitors to a science centre located in a major Western Canadian city were invited to participate in an experiment set up at the centre. their behaviors with a robot, a small 5 degree of freedom robot arm, were observed. Results of chi-square analyses indicated that children are most likely to help a robot after being introduced to it, X 2 (1) = 4.15, p = .04. this condition was the only one of five tested that demonstrated a significant increase in children's helping behaviors. these results suggest that an adult's demonstrated positive introduction to a robot impacts children's helping behaviors towards it.

this paper presents a concept for the virtual robot program development (VIPD) for assembly processes with industrial robots. the concept aims to the possibility to completely create and validate robot programs for assembly processes withthe help of a simulation environment. VIPD provides a consistent communication platform for the cooperative work of different project teams during the system engineering workflow. the paper focuses on the analysis and identification of the practically relevant requirements (II), which are described by a use-case from the automobile industry and the explanation of a suitable software architecture and its functional components such as a behavior component and a rigid-body simulator.

On the current situation where robots having functions of communication with humans begin to appear in daily-life fields, it should be considered how symbiosis of humans and robots can be achieved. Many existing studies have focused on how robots can learn from and adapt for humans. this full-day workshop focuses not only on this classical theme but also on how humans can learn in and adapt for environments where robots are acting. In particular, human learning from and adaptation for robots should be covered by interdisciplinary research fields including robotics, computer science, psychology, sociology, and pedagogy.

A novel feature extraction method of spontaneous electroencephalogram (EEG) signals for brain-computer interfaces (BCIs) is explored. the method takes the wavelet packet transform (WPT) as an analysis tool and utilizes two kinds of information. Firstly, EEG signals are transformed into wavelet packet coefficients by the WPT. And then average coefficient values and average power values of certain subbands are computed, which form initial features. Finally, part of average coefficient values and part of average power values with larger Fisher indexes are combined to form the feature vector. Compared with previous feature extraction methods, the proposed approach can lead to higher classification accuracy.
