Abstract

The invention discloses a two-dimensional motion control handle based on one-dimensional force sensors, wherein the two-dimensional motion control handle relates to the technical field of electromechanical automatic equipment. The two-dimensional motion control handle settles the technical problems of complicated structure, relatively large number of motion components and stability reduction in an existing two-dimensional motion control handle. The two-dimensional motion control handle comprises a handle rod, four one-dimensional force sensors, a connecting block, four springs, a spherical-hinge base and a base.

Description

technical field [0001] The invention relates to the technical field of electromechanical automation equipment, in particular to a two-dimensional motion control handle based on a single-dimensional force sensor. Background technique [0002] A motion control handle, also known as a joystick, is a common human-machine interface tool. Widely used in game joysticks, operating handles on industrial robots, cars, trains and other machines. According to the working principle, the motion control handle can be divided into potentiometer, inductive, photoelectric effect, Hall effect and so on. Traditional handles are generally potentiometer type, and the output is analog, which can directly control the actions of various driving components. Due to the existence of mechanical contact, the main disadvantages of the potentiometer handle are short life and poor anti-interference ability, so it is often used in occasions that do not require high precision. With the development of sensi...
