Design and Implementation of Intelligent-pharmaceutical-delivery-system Based on Loongson 1B

This paper design and implements an intelligent-pharmaceutical-delivery system based on Loongson 1B embedded technology. The system includes two physical parts: robot and PC station, and functionally includes control unit, delivery unit, medicine taking unit, and control App. The delivery unit’s functions are mainly implemented by OpenMV and PID algorithm. OpenMV installed on robot captures the images and extracts the line position data. PID algorithm is used with the position data to adjust the steering engine angle to ensure the robot walking along the line. A wheel motor encoder is adopted to calculate the walking length by counting pulse numbers. The medicine taking unit’s functions are implemented by machine vision and stepper motor. The control App sets tasks and assigns them to robot via wireless communication. Experimental results demonstrate the system accomplish the delivery tasks with high distance and position coincidence between the actual and pre-set targets.
