Data will be sent (via UDP/TCP) in string form. You'll have to use flatten to string and unflatten from string to, well, flatten and unflatten your data from a string. You'll have to supply the desired datatype when you unflatten (i.e. a constant that represents the cluster you've flattened). See the attached VIs in
this post to see what I mean. Then, once you get your data from the string, you can do whatever you need to with it - just as if it was any other input to your robot.
