Robot

Abstract

The invention relates to a robot. The robot comprises a base and a rotating seat; the rotating seat is mounted on the upper end surface of the base by means of a first rotating shaft; the rotating seat is connected with a first arm by means of a second rotating shaft; the first arm is connected with a second arm by means of a third rotating shaft; the second arm is connected with a connecting device by means of a fourth rotating shaft; a first stepping motor used for driving the first rotating shaft to rotate is arranged on the rotating shaft; a second stepping motor used for driving the firstarm to move is mounted at one end of the second rotating shaft; a third stepping motor used for driving the second arm to rotate is mounted at one end of the third rotating shaft; a fourth stepping motor used for driving the connecting device to move is arranged on the upper end surface of the connecting device; and the first arm and the second arm are corresponding arc-shaped bent arms with radians. The robot does not dependent on a servo-driven control module, the control module executes commands, the computation amount of a program is omitted, the cost of the control program is reduced, meanwhile, a mechanical arm adopts bent arm design, the turning radius is larger, the size of the robot is effectively reduced, and the robot is more convenient and reasonable during use.

Description

technical field [0001] The present invention relates to a robot. Background technique [0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom robots for the industrial field, which can grab and carry objects according to a fixed program. Industrial robots can replace people's heavy labor to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety, so they are widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy. [0003] Existing robots usually complete the rotation of each joint through servo drive, so as to realize the position movement, stay and speed change of the robot in space, etc., but to realize the above actions, it needs to rely on the control module of servo drive, and the control module executes The above commands require a large number of complicated calculation programs, which undoubtedly increases the control cost.

[0003] Existing robots usually complete the rotation of each joint through servo drive, so as to realize the position movement, stay and speed change of the robot in space, etc., but to realize the above actions, it needs to rely on the control module of servo drive, and the control module executes The above commands require a large number of complicated calculation programs, which undoubtedly increases the control cost. In addition, the mechanical arms of the existing robots are designed to be straight, resulting in a small rotation radius of the mechanical arms and increasing the volume of the robot, resulting in The mechanical arm of the robot is unreasonably stressed
