Description

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
