Hello, I have seen an article about calculating weight using get_tcp_force(), but is it possible to use the function to check for an object? 

I would like to move in the Z axis until a certain force is reached. 

How can I do that?

I can't think of a way to use get_tcp_force() live in an if statement.

I'm working on a system that had a prox switch to detect a part and they used a wait command until the prox went high. The prox is no longer and I need to use force sensing. Please help
