Abstract

The invention provides an open-loop control type manipulator aiming to solve the technical problem in the prior art that the conventional open-loop control type manipulator produces large displacement error when resetting. The open-loop control type manipulator comprises a rack and a manipulator body moveably mounted on the rack, wherein a first coil is arranged on the manipulator body; a second coil is arranged on the rack; the first coil and the second coil are connected in parallel to a power supply circuit; the position of the first coil mutually corresponds to that of the second coil; the cross section of the first coil is superposed with or parallel to the cross section of the second coil; during use, when the automatic resetting of the manipulator is completed, in the interval between which the manipulator stops resetting and the next loop begins, the first coil and the second coil are simultaneously fed with currents in opposite directions, and the first coil and the second coil are mutually attracted.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to an open-loop control manipulator. Background technique [0002] In the field of robot technology, the robotic arm is the most widely used automatic mechanical device, which is widely used in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. The robotic arm can accept instructions and accurately locate to a certain point in three-dimensional (or two-dimensional) space for operations. Generally, there are three movements: telescopic, rotating and lifting, which include open-loop controlled robotic arms and closed-loop controlled robotic arms. [0003] Among them, open-loop controlled manipulators are generally used in industrial manufacturing processes. The manipulator at the end is used to grab or move objects (including tools, workpieces or modules) on the assembly line. The basic function of th...
