Models and control strategies for dynamic obstacle avoid­ ance in visual guidance of mobile robot are presented. Characteristics that distinguish the visual computation and motion-control requirements in dynamic environments from that in static environments are discussed. Objectives of the vision and motion planning are formulated as: 1) finding a collision-free trajectory that takes account of...

This paper describes Off-Line and Real time motion conversion approaches for imitating the motion of a human being using a humanoid robot. In both cases, the human motion is measured with marker points captured by the 3D motion capture system Vicon. A similar physical morphology between the shape of the robot and the human is assumed. This paper also demonstrates that the input measurements of ...

This paper presents the coupled dynamics approach to executing Elementary Formation Maneuvers (EFM) for Hilare-type mobile robots. The concept of an EFM is presented. It is then shown that each of these EFMs posses a common mathematical structure and thus may be executed by the same type of robot control. We present three di erent EFM controls in this paper. The rst puts feedback on the relativ...

Presented is a new approach to multi-robot motion planning that is based on the concept of planning within dynamic robot networks. The system enables multiple mobile robots that have limited ranges of sensing and communication to maneuver safely in dynamic, unstructured environments. As the robots move about their workspace, localized robot groups form networks within which world models can be ...

Design a modular robot teaching device, combine with wireless communication technology, and robot control technology. Introduce ZigBee nodes into the robot’s every module, transmit the current motion parameters through the wireless communication, adjust the robot motion state and realize the fuzzy control of the robot motion. This device has good openness, does not involve the establishment of ...

In the paper, a novel new gravity-constrained (GC) three-wire-driven (TWD) parallel robot is proposed, and the prototype is presented with control system. With its mechanism model, three typical kinematic analytical models, including horizontal up-down motion, pitching motion and heeling motion and their corresponding simulations are given in detail. The open-loop and close-loop control scheme ...

OBJECTIVE The objective of this work was to examine human response to motion-level robot adaptation to determine its effect on team fluency, human satisfaction, and perceived safety and comfort. BACKGROUND The evaluation of human response to adaptive robotic assistants has been limited, particularly in the realm of motion-level adaptation. The lack of true human-in-the-loop evaluation has mad...

Many industrial robot arms are operated in industry, and some robotic applications in the industry, such as a pulling-out of products made by die casting, require the flexible motion excited by an external force. Here, the flexible motion means that the robot arm moves passively according to the external force. Industrial robot arms, however, are difficult to be moved by the external force beca...

This paper presents the intelligent wheeled mobile robot motion control in unstructured environments. The fuzzy control of a wheeled mobile robot motion in unstructured environments with obstacles and slopes is proposed. Outputs of the fuzzy controller are the angular speed difference between the left and right wheels of the mobile robot and the mobile robot velocity. The simulation results sho...
