DIY Robotic arm calibration using OpenCV and chessboard pattern.
Calibrating robotic arm is crucial for precise and reliable motion control. I wanted to find out if I will be able to calibrate kinematic parameters of my 3D printed robotic arm without using costly sensors, just utilizing OpenCV library and chessboard pattern. The main problem was, if it is possible to get reliable robot's position and orientation using camera attached to robot's end effector. For now I did it in my Unreal Engine simulator. Later I'll try this calibration procedure on the real robot. In this video I also cover such topics as : forward kinematics, Denavit-Hartenberg parameters and how to properly define them, how to compute Jacobian matrix, how to properly calibrate camera.
