Human-robot interaction is an important issue for service robots. In this paper, we propose to utilize the multisensory data fusion to autonomously detect and track an accompanist as a target person in the surroundings of the mobile robot. First, we use laser range finder to detect the target person features which is characterized using distances and orientations from range sensor readings. Based...
This paper reports experimental and analytical results of a Hybrid Mechanism Mobile Robot (HMMR) designed for field and military applications. The HMMR presented in this paper constitutes the second generation of a mobile robot that combines locomotion with manipulation in a symmetric invertible platform. The experimental results highlight the ability of the robot to operate in an unstructured environment...
This paper presents a new mobile welding robot system which based on rotating arc sensor as the seam tracking sensor. The system includes wheeled mobile body, two-dimensional motion platform, rotating arc sensor and ultrasonic sensor which uses as obstacle avoidance sensor. Two stage of tracking strategy is used in the system, that is the robot body rough tracking and the two-dimensional motion platform...
Mobile platforms when negotiating steps and stairs should be able to control theirs posture in order to avoid sudden tilting or falls. In particular, when considering applications for search and rescue operations where users have a very limited time of operation, the motion on stairs should be automated as much as possible. In this way operators can concentrate on their tasks (i.e. search of survivors...
