Abstract：Robot arm is a representative of modern society technology products, representing a higher degree of artificial intelligence. Its application is very extensive, involving all walks of life, and the trajectory planning problem of robot arm is an important research question belonging to the world's scientific research workers. The paper selects Abb1410 six-axis manipulator as the studying object, and introduces some of basic knowledge the robot arm in the spatial coordinates of the homogeneous transformation, and includes a brief description of the characteristics of the robotics toolbox and the use of basic steps of DH modeling precautions. Based on its structural parameters, its D-H model is established and subjected to positive and inverse kinematics analysis.
Then the paper introduces some common methods of establishing dynamical equations, such as Newton-Euler equation, Lagrangian equation and Kane equation. Then the paper selects Lagrangian equation Method to establish the mechanical arm of the joints of the dynamic equation according to the geometric parameters of the bar and inertia parameters.
The B-spline trajectory planning is selected by contrasting the algorithm, and the basic principle of the genetic algorithm is explained in detail. The energy of the obtained trajectory is optimized and finally simulated by MATLAB combined with Adams.
Keywords:Trajectory planning; dynamics; genetic algorithm; kinematics
