This article describes the related information of robot kinematics, including the solution of rotation matrix, vector and mechanical arm pose, and using C# to describe the relevant algorithm.
Rotation Matrix
The rotation matrix in linear algebra is used to make the vector rotate in the Euler space.
In robotics, the rotation matrix is used to solve the posture (orientation) of the robot joint. In three-dimensional space, the eigenvalue of the rotation matrix is 1.
