1. Degrees of freedom and degrees of freedom are the main goals to measure the level of robotics. The so-called degrees of freedom refer to the independent motion of moving parts relative to a fixed coordinate system. Each degree of freedom requires a servo axis to drive, so the higher the number of degrees of freedom, the more chaotic the actions that the robot can complete, the stronger the versatility, and the wider the scale of use, but the greater the technical difficulty it brings. In general, general-purpose industrial robots have 3-6 degrees of freedom.
2. The working space refers to the scale of the space where the robot uses the claw to operate. The wrist reference point for depicting the work space can be selected in the center of the hand, the center of the wrist, or the fingertips, and the size and shape of the work space vary depending on the reference point. The working space of the robot depends on the structure of the robot and the scale of movement of each joint. The working space is an important performance goal of industrial robots and an important goal for planning industrial robot institutions.
3. The carrying capacity refers to the maximum weight borne by the robot in any position within the scale of the operation, and the size of the carrying capacity depends on the quality of the load, the speed of operation and the size and direction of the acceleration, according to the different carrying capacity of industrial robots are roughly divided into: (1) micro robots - the carrying capacity is less than 10N; (2) Small robot - the bearing capacity is 10-50N; (3) Medium-sized robot - the carrying capacity is 50-300N; (4) The carrying capacity of large robots is 300-500N; (5) Heavy robots - the bearing capacity is more than 500N.
4. Movement speedThe movement speed affects the operation efficiency and movement cycle of the robot, and it is closely related to the gravity and azimuth accuracy extracted by the robot. The high speed of movement, the dynamic load borne by the robot increases, and it will inevitably bear a large inertial force during acceleration and deceleration, which affects the operation stability and azimuth accuracy of the robot. As far as the current technical level is concerned, the maximum linear motion speed of general-purpose robots is mostly below 1000mm/s, and the maximum rotation speed is generally not more than 120°/s.
5. Azimuth accuracy: It is another technical goal to measure the quality of robot operation. The azimuth accuracy of industrial robots includes positioning accuracy and repeated positioning accuracy, which depends on the azimuth control method and the accuracy and stiffness of the robot's moving parts themselves, in addition to being closely related to the extraction of elements such as gravity and motion speed. Repeated positioning accuracy is the accuracy of the robot to repeatedly locate a certain direction, and the positioning accuracy of typical industrial robots is generally in the scale of soil O.02mm-±5mm.
