1. An automated composite rebar (C-bar) bending system, comprising:
one or more non-rotatable and stationary supports, each having a circumferential side surface with separate upper and lower engaging portions,
a freely rotatable and movable support, having a circumferential side surface with separate upper and lower engaging portions,
a mechanical manipulation device connected to the movable support and configured to move the movable support relative to the one or more stationary supports, and
a controller directing movement of the mechanical manipulation device,
wherein each of the one or more stationary supports and the movable support are configured to grip an upper flange of a C-bar between the upper engaging portion of the movable support and the respective stationary support and a lower flange of the C-bar between the lower engaging portion of the movable support and the respective stationary support, such that a cylindrical body of the C-bar is not contacted by the supports.
