Robotic 2D Plotter

摘要

Robotic 2D Plotter is a plotter that offers the fastest way to efficiently produce very large drawings. The Robotic 2D Plotter which is basically a Selective Compliance Articulated Robot Arm (SCARA) has been implemented in the current work wherein the robot plots the input given from the computer on the drawing board using ATMEGA 8 microcontroller on a open-source physical computing platform Arduino. The Robotic 2D plotter has a two axis control and a special mechanism to raise and lower the pen. Each axis is powered using a single servo motor. Pen control is achieved using a servo. SCARA is an autonomous robotic arm with three Degrees of Freedom (DOF) and two joints which are flexible along the X-Y axis but rigid along the Z axis. This arrangement allows the arm to perform tasks at a faster pace and with increased accuracy.
