During calculations using minimum Distance formulas from ISO 13855 I have ran into a question as to what exactly the variable Vs is when calculating Ss (contribution to the stopping distance from the robots stopping distance). Vs is a function dependent on time of the robots deceleration. Where could I find the robots maximum deceleration for this. Also if anyone can provide a sample calculation of this that would be much appreciated. I have calculated this as a worst case scenario but am not happy with the separation distance, therefore I now need to consider the actual scenario.
