Lego NXT Bluetooth Linewriter

Grade 12 Robotics Project

The Lego NXT Bluetooth Linewriter was a stationary robot constructed to trace lines, curves and letter using a pen on paper. Two motors controlled the paper rollers, one moved the print head, and another motor controlled the pen. Due to the amount of motors, two NXT control units were required to drive the motors. They communicated with each other and the controlling computer using Bluetooth.

Input to the printer can be provided either as a text string, or in "Etch-a-sketch" mode, manually using the arrow keys.
