I am working on calculating the Jacobian Determinant to find the singularity of my 5 DOF Robotic arm, I have calculated the jacobian matrix, and the matrix I got is a very large value As it is non square matrix(6x5),For singularity I am using Pseudo Inverse method( I studied in a Research Paper) Jinv=(Jtrans)(Inverse(JJtrans)) But In Matlab when I calculate the Inverse of (J*Jtrans) It goes Out Of memory, what is the alternate or right method to do that I know It is not the Matlab forum but I want to know is that right jacobian matrices Or I am doing some thing wrong in calculating the jacobian( as being very large matrice)I am also attaching the code am using
Are you trying to somehow use this to determine lengths of the linkages later or are you trying to find the singular pose of one specific manipulator?
In case you are doing a study on how to calculate linkages lengths, you need a PC with more RAM if you want to progress.
If you already have values for the lengths, you should not use these as symbols, just use them as values instead. The only symbols should be the joint angles. That will make the matrix smaller and will fit in memory.
