Follower robot count (research) increases the maximum number of follower robots that can follow the player at any point in time. This limit counts for Defenders and Destroyers; Distractors do not count against the follower limit.
Remember that the cumulative effect starts with 5 due to researching combat robotics giving 1 to max followers.
