Hi Pros, 

Some customers need to deal with process variances which are known (e.g. input from previous process or sensor). An example would be a part which needs to be picked from a position, which can vary in one or multiple dimensions (e.g. +-20mm). This deviation is measured via a sensor and provided to the robot controller. The robot adjusts the picking position accordingly.
