Description

A fighter's fist or a boxer's glove when it reaches a punching bag will have a force dependent on how fast the fist or glove is speeding up and the mass of the fist or glove and arm.

Details

The punch force is characterized as AFMFD. Atttack-Forced-MAXimum-Forced-Decay. the buffer of PAD delay the maximum force coming, that is, a sharp force comes firstly, and then when the elastic get to the tipping point， the maximum force arised.

The project is scheduled to use Arduino to sense the forcing data, and then communicate with processing to visualized the data. (UPCOMING!)

Roadmap:

Prototype 1

Roadmap:

Prototype 1 (Unreleased)

FSR Sensor evaluation
Arduino data collection

Prototype 2 (Unreleased)

UART communication to processing
Processing data pilot

#3 Further Progress:

Add blu-tooth function and connect it to android app(processing IDE)

see below curve in 10ms sample delay.

P1: Fist Target is ready.

Get a 20x20CM fist targe, it was mount on the wall. FSR sensor is attached also.

Await next step to connect to arduino
