EMC Shielding for ArduCopter3.0

The EMC shielding material reduce magnetic interference that is good to ArduCpoter3.0.

Measurement of magnetic interference becomes half by 60micron meter low-loss,high permeability nano-crystalline material.

Without magnetic shield…


How should we dealing with Li-ion Battery for flight safty?

Posted on January 17, 2013 at 2:55pm 16 Comments

As you know the Boeing 787 has been grounded by caught fire on the Li-ion battery.

It looks like Japanese battery may have some issues on this incident:-(

You might reminded some laptop PCs caught fire by its Li-ion battery, few years before.

It is ironic to the restriction of Li-ion batteries for carry on baggage and air cargo.

Our copters…

What do you fly and is your field close to Tokyo? I'm located in Meguro and mainly into UAV aircraft, although just started to fly a KKmulticopter.

I'm living in Atsugi. It looks like lots of space to fly air craft in Atsugi. However, there are very few places to flay.

This is my main frustrated issue. You can visit my web site. It is some sort of language translation web site. http://aeroquad.at.webry.info/

Jiro, thanks for the suggestions on demonstrating the heli in Tokyo.  I might give that a try at the Tokyo Institute of Tech.  I guess the make fair is at the ookayama campus.  I'll ping you when I'm getting close to being ready..

Hi Jiro, I have an issue regarding the use of xbee with pixhawk, I'm using xbee as follows, 

but I´m still having problems. I write the next program to try send some data but I don't get any positive results.

#include <AP_Common.h>
#include <AP_Math.h>
#include <AP_Notify.h>
#include <AP_Param.h>
#include <AP_Progmem.h>
#include <AP_InertialSensor_MPU6000.h>
#include <AP_InertialSensor.h>
#include <AP_ADC_AnalogSource.h>
#include <AP_ADC.h>
#include <GCS_MAVLink.h> // Rediculous dependency to AP_InertialSensor_MPU6000
#include <DataFlash.h> // Rediculous dependency to AP_InertialSensor_MPU6000
#include <AP_GPS.h>

#include <AP_HAL.h>
#include <AP_HAL_AVR.h>
#include <AP_HAL_AVR_SITL.h>
#include <AP_HAL_PX4.h>
#include <AP_HAL_Empty.h>


AP_HAL::AnalogSource* ch;
AP_InertialSensor_MPU6000 _INERT; // MPU6050 accel/gyro chip

void setup (void) {
hal.uartA->begin(115200); // USB
hal.uartC->begin(57600); // RADIO

_INERT.init(AP_InertialSensor::COLD_START, AP_InertialSensor::RATE_100HZ);

void loop (void) {

hal.uartA->write("start \n");



Do you have an idea of what is happening?

Thank you in advance.
