Project Overview

This semester, our project is to design a system that will allow a user to track basic tennis swing movements. Currently, there are are a few companies that provide this kind of tracking; however, the most established of them require that the player purchase a specific racket. Others are not as accurate or have a lot of reviews where the sensor flies off of the racket. What we hope to accomplish with this project is to have a detachable device that will be able to provide raw data from a 6-DOF IMU sensor attached to the racket, and have that data sent to a computer for processing. From this data, we hope to provide simple feedback, such as swing count, consistency, and swing speed.

For our project, we will be collecting data by using a combined accelerometer and gyroscope to track swing movements. By the end of the semester, we will be able to show data collected from a tennis racket being swung. As two former college tennis players, we will be able to look at the swing and provide some feedback on how to improve it.

Project Objectives

  • Creating a detachable device that collects kinematic data on the swing of a tennis racket
  • Be able to extract raw data from the onboard IMU and send to a computer for processing
  • Use collected data to calculate swing speed
  • Reconstructing swing based on data collected from the IMU sensor
  • Use the data to be able to visualize/animate the user's swing

Project Challenges

  • Setting up an Arduino with proper modules
  • Being able to process data from the IMU to the computer in real time
  • Using kinematics and understanding of translational frames to interpret IMU data
  • Writing script in Matlab that will allow easy interpretation of raw data


  • Parts Ordered Online
    • Arduino Nano ($30)
    • MPU6050 Module, Accelerometer and Gyroscope ($6)
    • Mini Breadboard ($5)
    • XBee Radio Modules ($20 each)
  • Hardware and Miscellaneous Items ($30.00)
    • Various connectors
    • 9V Battery
    • XBee adapters
    • And other unforeseen items necessary for assembly
  • We would like to keep another $30 in reserve, just in case we run into a hardware problem or we accidentally break the Arduino/modules during testing.

Total: $141 (including the $30 reserve)
