Re : robotic

I tried to manipulate a two degree of freedom robot with the inverse kinematics, well I initiallized two angle but I want to return the results in the beginning of program because I want to command with other positions so I have to use the previous angles and positions ,I have used shift register but it doesnt work cause I must have a loop (for or while ) but I didn't need loops ! help please !!

Hello,

To return values to the beginning of the program, the most common method is using shift register. Why do you "not need loops"?  If we are returning values to the beginning of the program, it makes sense to run the program again (with a loop).

You can move variables around without using shift registers with local variables for instance (https://www.ni.com/docs/en-US/bundle/labview/page/using-local-and-global-variables-carefully.html)
