Inverse kinematics in LabVIEW

[Himanshu]

I would like to know about any fresh ideas for Inverse Kinematics of Robotic arm. I have a robotic arm, which has 4 links. I am sending a doc file which has the detailed description of the Inverse Kinematics and the algorithm which I have implemented using LabVIEW. Although I think the algorithm is correct but I am unable to make the arm move along a straight line. It would be nice if any one of you could please send me any ideas for implementing the same

I thought it would benefit others to put all of the responses to this question together.

Suppose the caculate is correct,it should run no problem.my robot arm is work well.

i think maybe the initial position of your robot arm is not correct.

the problem should be caused by the diference between math method and the arm.
