iPaddle: An Intelligent Swimming Training System

This paper presents an implementation of an intel-ligent swimming rowing system which consists of a swimming paddle attached to a motor connected by an inextensible cable. This system consists of a combination of two elements to create a device that simulates an aquatic environment out of water The first element consists of: an inertial system measurement unit, a communication device and a battery; all placed inside the swimming paddle. The second element is composed of an odometric arrangement consisting of an effort returning motor that coils the cable to compute by odometry the distance from motor to the paddle. In combination with the acceleration and rotational speed provided by the IMU, the motor apply resistant to simulate an aquatic environment. This device has proved is uttility because as being out of the water, the coach has a better control to analyze and correct the swimming technique of the athletes. Moreover, position, speed, acceleration and effort done by swimmer can be analyzed later offline.
