Music playing robotic arm

The precision and accuracy of the movement of the robotic arm is a vital criterion for design in applications such as high-precision medical surgeries, vending retrieval systems and industrial automation. While normal servos can be used for resolutions up to 255 bits in five degrees of freedom, actuators provide much better control and less steady-state error. This thesis highlights the manipulation of a single robotic arm to play musical notes on a synthesiser piano with the help of Arduino. The calibration of the arm was done using RoboPlus and LabView software, and the error percentages between the theoretical and experimental precision values were measured and analysed. The robotic arm was deployed to work at various speeds, and the difference in completion times of musical notes between the robotic arm and human arm was explored. This project hopes to open the door for further improvements of the model in the near future and act as a reference for more advanced automation systems.
