Purpose – The purpose of this paper is to develop a portable all‐position welding robot for the welding of intersected pipes. Design/methodology/approach – A complete procedure is adopted to conduct the design. The task and motion of the robot are analyzed and a mathematical description of...

Purpose – The purpose of this paper is to present a new nested rapidly‐exploring random tree (RRT) algorithm for fault tolerant motion planning of robotic manipulators. Design/methodology/approach – Another RRT algorithm is nested within the general RRT algorithm. This second nested level...

Purpose – The purpose of this paper is to propose a universal approach for configuration synthesis of reconfigurable robots based on fault tolerant indices. Design/methodology/approach – A universal approach is introduced to determine the best configuration of redundant reconfigurable robots...

Purpose This paper aims to deal with the problem of designing robot behaviors (mainly to robotic arms) to express emotions. The authors study the effects of robot behaviors from our humanoid robot NAO on the subject’s emotion expression in human–robot interaction (HRI)....
