Two-Axis SCARA Robotic Arm with LCD (24) ECE342-W25

The Two-Axis SCARA Robotic Arm with LCD is intended for drawing. The system takes in G-code inputs through a Bluetooth connection using a GUI and performs the corresponding movement associated with the G-code input. The system also displays the current G-code input through a LCD. The arms were 3D printed and designed in Autodesk Inventor. The system use two distinct voltage regulators to ensure components get their specified voltages. In this case the esp32 and LCD get a voltage of 5 volts and the motors get a voltage of 6 volts. The system uses kinematics equations to calculate the angle each arm must take, ensuring the drawing utensil reaches its precise destination. Our most notable accomplishment was to incorporate a Bluetooth connection which was used for the G-Code inputs. For future improvements we would incorporate a custom PCB which make the assembly of the system easier while also having a nice presentation. We would also transition from servo motors to stepper motors in order to make more accurate drawings.
