Upgrade your RC Transmitter with a DIY Tilt Motion Control Module

If you are into Radio Control Models or robotics chances are that you have an old RC transmitter laying around. This article describes how to create a motion control module for your RC transmitter, that will allow you to control your model or robot by simply tilting the transmitter case. That's right not sticks!

Play PC games the iPad style – Using a PIC with USB, accelerometer and optional Gyroscope

The iPad is finally out – one feature that might caught your attention is the built-in accelerometer and the ability to control a game by tilting the device. For more than a year I was working on a similar idea for the PC Notebook market based on my original  motion gamepad project that would  allow playing a game by tilting the laptop/netbook. Now that iPad is out I hope that the notebook/netbook manufactures will catch up by incorporating MEMS sensor into their devices. Here is the result of my prototype , it is a USB attached device, but ideally I think this should be embedded into the laptop.

A Guide To using IMU (Accelerometer and Gyroscope Devices) in Embedded Applications.

Introduction

There’s now a FRENCH translation of this article in PDF. Thanks to Daniel Le Guern!

This guide is intended to everyone interested in inertial MEMS (Micro-Electro-Mechanical Systems) sensors, in particular Accelerometers and Gyroscopes as well as combination IMU devices (Inertial Measurement Unit).

Acc_Gyro_6DOF  and UsbThumb MCU unit

Example IMU unit:  Acc_Gyro_6DOF on top of MCU processing unit UsbThumb providing USB/Serial connectivity

I'll try try to cover few basic but important topics in this article:

– what does an accelerometer measure
– what does a gyroscope (aka gyro) measure
– how to convert analog-to-digital (ADC) readings that you get from these sensor to physical units (those would be g for accelerometer, deg/s for gyroscope)
– how to combine accelerometer and gyroscope readings in order to obtain accurate information about the inclination of your device relative to the ground plane
