[0072] Example 1
[0073] figure 1 Shown is a flow chart of a variable-parameter neural solver design method of an example of the present invention; a variable-parameter neural solver design method for redundant robotic arm motion planning, comprising the following steps:
[0074] 1) Formalize the task to be solved into the performance index and constraint conditions of the redundant manipulator, that is, model the actual redundant manipulator parameter index, and establish a physical system model;
[0075] 2) Convert the physical system model in step 1) into the time-varying quadratic programming standard form of the system;
[0076] 3) According to the Lagrange multiplier method, the quadratic programming model in step 2) is optimized for the optimal value;
[0077] 4) converting the optimization information in step 3) into a standard time-varying matrix form;
[0078] 5) Design deviation function equation based on the matrix in step 4);
[0079] 6) Based on the deviatio...

[0127] Example 2
[0128] In order to demonstrate the actual system design process, an example of a 6-DOF robotic arm is used to illustrate the problem: the MATLAB simulation experiment of this example is based on Kinova-JACO 2 Based on the lightweight bionic robotic arm. The total weight of this type of robotic arm is 4.4kg, and the maximum control distance is 77cm.
[0129] This type of redundant manipulator contains a total of 6 degrees of freedom, that is, θ(t) contains 6 elements; the spatial dimension of the end of the manipulator is 3, including the three directions of X axis, Y axis and Z axis; Its Jacobian matrix is The starting joint angle of the redundant manipulator is set as θ(0)=[1.675,2.843,-3.216,4.187,-1.710,-2.650]; the task execution period t is set as 8s; the parameter γ is set as Set at 50. In this example, in order to demonstrate the superiority of the variadic neural solver for redundant manipulator motion planning proposed by the present invention,...
