Mimicking 5-DOF Robotic Neck Through IMU MPU6050 Sensor with Movement Compensation

This study aimed to develop a mimicking robotic neck with 5 degrees of freedom. The proponents made use of Inertial Measurement Unit (IMU) sensor attached to the user’s head, neck, and body to compute for the flexion and extension, lateral bending, rotational, hyper flexion and hyper extension, and hyper lateral bending motion of the neck. The study aimed to address the limitation from previous studies which is the absence of independent tracking for upper neck motion and lower neck motion. The proponents applied Movement Compensation and Complementary Filter in the computation to obtain the desired angles of the human neck. The proponents used Arduino and LabVIEW software for extraction of the data to be used. The system is analyzed using Wilcoxon Testing, to evaluate the response of the robotic neck to the user's movements. The result shows that the control system and mimicking robotic neck effectively measures and imitates the human neck. Furthermore, the results show that that system effectively tracks the upper neck and lower neck motion independently.
