From the documentation: "The simulator detects all contact points that fall within a given sensor zone and involve the body to which the sensor is attached. The contact normal forces of all detected contact points are then added up (as scalars and not vectors) and the result is returned as the output of the simulated contact sensors. Thus the sensor units are Newtons." Does this mean that we won't be able to distinguish between an indentation of a very sharp probe at high force versus an indentation with a big probe at low force? Since these will produce drastically different neural responses, it is crucial to distinguish between the two. What is the suggested course of action to decipher between the two types of contact?
