In order to help patients achieve effective and coordinating multi-joints movement easily, the paper presents an active training method of a lower limb rehabilitation robot based on constrained trajectory. The realization process of the method is as follows. The patient's movement intention is recognized by analyzing the signals from torque sensors installed in rehabilitation robot joints, and the...
In this paper, we tested a dynamic control law on a 2DOF robot walking leg. To achieve this, we modeled the system using bond graphs, and the Sliding Control Method for real time control. To increase performance of the robot trajectory tracking control a fuzzy gain adjustment inside the dynamic control method have been used and the new results include the systems' influence on the sliding parameter...
A fuzzy controller is established for the wire feeder of the invasive vascular interventional surgery robot in this paper. First of all, the mechanism of the wire feeder is introduced, and the axial motion is analyzed. Second, the dynamic model of the wire feeder is established. Next, the fuzzy PID controller is established to improve the positional accuracy and dynamic performance. At last, the controller...
The paper presents a new approach on haptic interface control for NAO robotic hand. The haptic teleoperation of NAO robot hand raises some issues, mapping the haptic device dynamic being the most important. The mapping was achieved through Neural Network by determining a dynamic gain of robot haptic feedback. The results lead to the achievement of the haptic intelligent interfaces for the NAO robot...
