As shown in fig. 1, the present invention comprises the steps of:
the method comprises the following steps: and analyzing the working performance of the cooperative robot, and determining the working performance index parameter value of the robot according to the working task of the robot.
According to the robot operation type, the robot is divided into a low-load robot, a medium-load robot and a high-load robot, wherein:
(1) the low-load robot mainly performs the work of circuit board assembly, visual inspection and the like, and the requirements on the working performance of the low-load robot are low load and high speed (the load is 0.5 Kg-20 Kg, and the tail end speed of the robot is more than 10 m/s);
(2) the medium-load robot mainly engages in the work of toy assembly, part transportation and the like, and the working performance requirements are medium load and medium speed (the load is 20 Kg-60 Kg, and the tail end speed of the robot is more than 5 m/s);

And 2.1, carrying out configuration optimization on the cooperative robot, wherein the working performance indexes of the cooperative robot comprise the freedom degree and the working space of the robot.
In the step 2.1, according to a reference document ' Humingwei, Kinghonang, Panxinan ', and the like ', a cooperative robot motion performance analysis and simulation [ J ] is reported by an intelligent system, 2017,12(1):75-81.
And 2.2, performing precision optimization on the cooperative robot on the basis of the step 2.1, wherein the working performance indexes of the cooperative robot comprise robot pose repeatability and pose accuracy (robot precision).

Obviously, the working performance indexes of all robots cannot be improved on the premise of ensuring the safety of human-computer interaction. In fact, the safety design of the cooperative robot is that the safety of the robot is balanced with the working performance indexes, and the performance indexes are independent or coupled.

The analysis of whether or not there is coupling between the various performance parameters described above is well known in the art.
According to the method shown in fig. 4, the design parameters of coupling and decoupling of the working performance and the safety performance of the robot can be obtained through correlation analysis, for the decoupling design parameters, the decoupling design parameters are optimized to ensure the improvement of the working performance of the robot, such as the maximization of the robot precision, the maximization of the robot dexterity and the like, and for the coupling design parameters, optimization calculation is performed through an optimization algorithm, and since the rated load of the robot is usually a set value during design, the parameters of the effective mass (light weight) and the terminal speed (agility) of the robot are selected to be optimized according to the method shown in fig. 4.
