Abstract: An action teaching method is provided for teaching a robotic arm of a robotic arm system through a gesture teaching device. In a step (a), a touch condition of a user's finger is sensed by the touch sensing unit. In a step (b), a sensing result of the touch sensing unit is transmitted to an identification unit, so that a touch information is identified by the identification unit. In a step (c), the touch information is transmitted to a teaching unit, so that the teaching unit actuates a corresponding operation of the robotic arm system according to the touch information. In a step (d), an operating result of the robotic arm system is shown on a display unit, so that the user judges whether the operating result of the robotic arm system is successful through the display unit.

Abstract: An automatic alignment system of a robot manipulator is provided. The automatic alignment system includes a signal transmission module and a controller. The signal transmission module includes a first signal receiving and transmitting element and a second signal receiving and transmitting element. The first signal receiving and transmitting element is mounted on the robot manipulator. The second signal receiving and transmitting element is disposed neighboring to a target workpiece. A signal is transported between the signal receiving and transmitting elements. The controller is electrically connected with the signal transmission module for receiving the signal outputted from the signal transmission module. The controller acquires a relative position between the first signal receiving and transmitting element and the second signal receiving and transmitting element according to a variation in the signal. The controller controls the robot manipulator to be automatically aligned to the target workpiece in accordance with the relative position.
