Platform progress

Tom and I have made a couple of decisions and are moving forward.



"I would not be just a nothin' my head all full of stuffin'

...

If I only had a brain."




I purchased and have received a standard Arduino Duemilanove board. I strongly considered the ArduPilot, but I wanted to get up an running quickly and I didn't really want to spend the money for an FTDI Serial / USB cable. I've been doing some basic bootstrapping to get a few things up and… Continue

Dreaming of wings

My name is Brian Hudson. I've been wandering around DIY for a week or two now, and I've decided to start this blog to start interacting with the community, get feedback, and to track progress and thoughts on a project my neighbor and I are starting.



My background is in Computer Engineering and Computer Science and I've worked in the software industry for several years now. My neighbor has a degree in Aeronautical Engineering, and we’ve been talking for awhile about a UAV… Continue

hey Brian

Thanks a ton for the info u gave i'll definitely try it today. And no, I have not loaded my own code onto the IMU. Still using the default firmware. I am an undergraduate and totally new to all this. So can u also tell me how to load my own code onto the IMU. I want only the gyro reading passing through the Kalman filter. So pls cann u help me with that.

thanks again
Abhishek

hi Brian..
Thanks for the early reply..
I was thinking of just using the output from the three gyros and connecting the 'Out', 'Gnd' & '3.3v' pins directly to analog inputs of arduino.
Wat do 'PD' and 'ST' pins indicate??
i would really appreciate if u cud send a picture of ur imu setup with the arduino..
you can simply mail me on agarwal_apoorv_bits@yahoo.com

abt coding stuff, we have a previous experience of working in a couple of competitions and all..
so not a very big problem modifying the source code..
we have a isp programmer for avr.
we are uising winavr 2008 software..

we are a team of 4 members.
all from the same engineering col.. we are pursuing degree in chemical and (two of us in) electronics and mechanical..


thanks a lot again...

also wat abt the part where they have mentioned in the atomic datasheet that we are not supposed to connect the imu to a rs232 line.(probably due to high voltage)..
At 9:41pm on June 5, 2009, Abhishek Jain said…
i got that part abt connecting to the xbee socket.
you are using the analog I/O pins and connecting it to the arduino,, ryt??

hello again

Do you know the exact weight of the Atomic IMU


thanks in advance

Namaste

How do i convert the gyro readings to angles.

I have mapped the functions between -300 to 300 on my Arduino alpha.

Pls help out

Thanks

hello

i know its been long. I have finally figured out the PID control loop for the motors and the pinouts for the x,y axis of the accelerometers. Have only one problem. Don't know how to get the output from the z-axis of the accelerometers. Can't get the pinout except the pin on the ATmega. Don't want to use it for fear of wrecking the ATMega. Can u tell me how to get the analog reading for only the z-xis

Pls tell me at the earliest

Thanks

Hello

Can u send me a circuit diagram of your connections from the SF IMU to the Arduino. I am having a problem. Am not able to get the pinout for the z-sensor. And can u post a better photograph of your Arduino+IMU setup.

Thanks
