A surgical robotic system is configured to enable user confirmation of whether one or more access ports are standard or longer length (e.g., bariatric type access ports). The system includes a surgeon console having one or more hand controllers and a head tracking device configured to detect surgeon's attempt to actuate an end effector of an instrument disposed within the access port. The system prevents actuation of the end effector until the insertion depth of the instrument is sufficient or the user confirms that the access port is of standard length, e.g., less than a preset length threshold.
