Nevertheless, several selleck KPT-330 issues remain regarding the control of robotic arm movement on an established track. For example: (a) accurately controlling an end effector with 6-DoF is extremely difficult and time-consuming because every degree requires an exclusive sequence of button actions; (b) executing robotic arm movements according to scheduled tracks are extremely difficult because of an increased number of interpolation points are necessitated for complicated movements, thereby raising the complexity of operation; (c) improper use of the teach pendant can damage the robotic arm or hurt the operators; and (d) the teach pendant cannot be operated intuitively, which is not efficient. Because of these problems, robotic arms are not sufficiently user-friendly and can only be competently directed by experienced operators.

Consequently, numerous factory owners are not willing to incorporate robotic arms into their Inhibitors,Modulators,Libraries manufacturing processes.Compared to previously developed teach pendants, HMI and human-computer interfaces (HCI) technologies have become sufficiently advanced to enable people to operate robotic arms easily. For example, researchers have attached sensors to human arms or bodies to control robotic arms through body movement. In [11] accelerometers attached were to both human arms to control a robotic arm; the right arm controlled the X, Y and Z directions in the Cartesian system, and the left arm controlled the Inhibitors,Modulators,Libraries orientation. The authors of [12] attached electromyography (EMG) sensors to a right human arm, which controlled the movement and rotation of a robotic arm, and the opening and closing of the attached claw.

In [13] and [14] the various joint movements captured Inhibitors,Modulators,Libraries by motion sensors were recorded and the results applied in controlling robotic arms. Although these studies enabled users to operate robotic arms intuitively, the methods were unable to calculate the optimization accuracy for the endpoint position of the robotic arms, rendering these methods incapable of positioning and posing the endpoint of the robotic arms accurately. Consequently, these robotic arms were only used for tasks with simple movements.In addition, numerous researchers have adopted joysticks and haptic devices to teach and control the robots. In [7] a joystick Inhibitors,Modulators,Libraries was used and a force/torque sensor attached to the endpoint of a robotic arm; fuzzy compliance control was applied to direct the robotic arm strength for sanding.

In [15] the authors used a Wii remote and headset to control a robotic arm. GSK-3 The Wii remote recognized human actions and controlled the 3D movement and rotation of the robotic arm, and the headset recognized human voice commands. In addition, a force-torque sensor was attached to the end point of the robotic arm to control strength. In [16�C18] the Phantom Omni 6-DoF force-feedback joystick was used to control robotic arms, which enabled product information the operators to feel the feedback from the robotic arms and robot environment.
