Human-robot control interfaces have received increased attention during the last decades. These interfaces increasingly use signals coming directly from humans since there is a strong necessity for simple and natural control interfaces. In this paper, electromyographic (EMG) signals from the muscles of the human upper limb are used as the control interface between the user and a robot arm. A switching...
A master-slave system has been used to operate a robot. This system is necessary to communicate human intentions to the robot. In this context, we focus on Myo-Electric (ME) potential. In many previous studies, a motor is used as an actuator, and the torque and position are estimated from the ME potential. However joint stiffness, which humans can change, is not considered. It is possible to solve...
This paper bispectrum is used to classify human arm movements and control a robotic arm based on upper limb's surface electromyogram signals (sEMG). We use bispectrum based on third-order cumulant to parameterize sEMG signals and classify elbow flexion and extension, forearm pronation and supination, and rest states by an artificial neural network (ANN). Finally, a robotic manipulator is controlled...
It is well known that the massage therapy is useful for the rehabilitation of various diseases (i.e. oral health problems, etc.). Although various apparatus have been developed for the massage of the torso and limbs, there is still little knowledge about their real effectiveness. For this purpose, authors have proposed the development of a robotic system that provides massage therapy of the maxillofacial...
This paper presents a redundant manipulator with a new application to relaxing human-body muscle fatigue. The environment between human-body and the manipulator end-effector is modeled as a mass-spring-damper system. Then the generalized impedance control method is used to control the manipulator in the task space as well as the null space. To get the optimized solutions, the objective function is...
Human-robot control interfaces have received increased attention during the last decades. With the introduction of robots in every-day life, especially in developing services for people with special needs (i.e. elderly or impaired persons), there is a strong necessity of simple and natural control interfaces. In this paper, electromyographic (EMG) signals from muscles of the human upper limb are used...
A parallel and flexible meso-manipulator for finger rehabilitation treatments is presented in this paper. The work deals with the study of a meso-robotpsilas kinematic and dynamic peculiar behavior, aimed at allowing its application to muscular activity and tendon tension, in those patients with even a partial lack of the fingers functionality, for instance due to a stroke. As a result of its structural...
