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.
