On the Design and Development of a Motion Control System using Accelerometer and RF Communication

This paper presents the design and development of a motion control system using a MEMS Accelerometer and RF communication with Atemga16 microcontroller. The accelerometer sensor can detect the tilt in all three axes and accordingly generate a corresponding analog output voltage. The generated analog output is converted into 10 bit digital output which is compared to the reference voltage mentioned in the datasheet of accelerometer. It helps to detect the direction of the motion (+x,-x, +y,-y) and accordingly the 4 bit data from microcontroller is sent to RF encoder. At the receiving end the data received by the decoder is sent to microcontroller. The data received is compared and the direction is detected using the programmed logic. A DC motor, guided by the microcontroller, serves to demonstrate the controlled motion.
