In this study, we propose a multi-portal human interface (M-HI) as an innovative human interface for power assist systems. The M-HI allows users to apply the operational force anywhere in the power assist system. Because of that, the workspace of the power assist system is extended with their end-effecter can be controlled as user think. We design the M-HI considering the user's line of sight. Because...
This paper proposes a method for interpretation of fuzzy voice commands based on the vocal cues. The fuzzy voice commands include fuzzy linguistic terms like “little” and quantitative meaning of such terms depends on the environmental conditions. Therefore the robot's perception of the corresponding environment is modified by acquiring the user's perception through a series of vocal cues. The user's...
In this work, a novel comprehensive scheme for the coordinated control of remotely operated vehicle-manipulator systems (ROVMs) is proposed. In the proposed scheme, instead of commanding the motion of the vehicle and the manipulator separately, a human pilot commands only the manipulator's end-effector motion using a parallel- architectured six-degree-of-freedom (6-DOF) joystick. The generated reference...
Reflexology is a kind of assisting physical care through massaging or applying pressure to parts of the feet where will reflect an image of the human body in order to improve general health of the human. Based on this principle, we propose a new application of 7-DOF(degree of freedom) redundant manipulator to do the massaging work for human feet with the tactile sensor equipped to the end-effector...
In this paper, we present an arm wrestling robot (AWR) system. This system is designed with the purpose of imitating the real force-applying process of human player when people play in the game of hand wrestling. In order to achieve the expected function, special mechanical structure of robot arm is designed in according to human hand, two force sensors and a motor with special driver are adopted...
A novel haptic teleoperated scheme for an efficient obstacle avoidance under human guidance is introduced. A remote robot immersed in an environment with obstacles is guided by a user using the end-effector of a haptic device. The system provides force feedback to the user when he approaches a potential field surrounding an obstacle. The user assigns the potential fields to the obstacles based on...
Our key motivation is the rehabilitation of individuals recovering from stroke or other neurological insult. The torque exerted by a cable-driven joint is the cross product of the line of action of the cable, known as the moment arm, and its tension. The subject of this article delves into this latter, less-studied quantity associated with torque. The concept of moment arm manipulation of a cable-driven...
In this paper we present a methodology to drive the end effector of a robotic manipulator, to which is attached a human hand, in order to follow the human's intention of movement. This set-up is inspired from a neuro-robotics scenario in order to develop systems for restoring motor functionalities in injured and disabled people. Three typical tasks are considered, namely the robot not to interfere...
