Q: How many different kinds of robotic devices are there? — T.R., Boca Raton, FL

A: There is only one, the robot called the ARTAS System for FUE, made by Restoration Robotics. The Neograft machine, occasionally confused with a robotic device, is actually a hand-held instrument that is not robotically controlled and lacks image-based tracking. It is, therefore, not capable of eliminating the operator error and variability of hand operated devices and does not decrease the damage to follicles, called transection, inherent in manual techniques.
