Hey, Anyone have any suggestions for the following: I am building an autonomouse aircraft for a school project; I need pitch and roll sensors. Any suggestions? (would like something to give me either analog (degrees) or words if they exist) Timber [Non-text portions of this message have been removed] |

Depending on how much money you want to spend, you could use Murata or Tokin or similar gyros for relatively low cost systems. Probably an ADXL202 would work for the accelerometers -- check out the BasicX app notes for information. Or if you have lots of money, check out these off-the-shelf systems: http://www.xbow.com/Products/Inertial_Systems.htm -- Frank Manning -- NetMedia, Inc. |

It's not a gyro, but senses the horizon and keeps the airplane level. http://www2.omnimodels.com/cgi-bin/woi0001p.pgm?Q=1&I=FUTM0999&P=O Mike Donovan ----- Original Message ----- From: "Frank Manning" <> To: <> Sent: Saturday, September 14, 2002 12:19 PM Subject: Re: [BasicX] need some ideas > From: "Wolfe Digital Systems, Inc." <> > > > I am building an autonomouse aircraft for a school project; > > I need pitch and roll sensors.

I assume you have searched the net for systems that are low cost < $1200 and are sold. They have tech info on how they work, too. hint: there are two popular systems out there. There is also this optical system, about $120 https://www.fmadirect.com/site/fma.htm?body=Products&cat=20 It is better than the futaba. Not as easily 'fooled' by lighting conditions. It looks at IR. supposed to work at night too. -Les -----Original Message----- From: Mike Donovan [mailto:] Sent: Saturday, September 14, 2002 10:49 AM To: Subject: Re: [BasicX] need some ideas It's not a gyro, but senses the horizon and keeps the airplane level. http://www2.omnimodels.com/cgi-bin/woi0001p.pgm?Q=1&I=FUTM0999&P=O Mike Donovan ----- Original Message ----- From: "Frank Manning" <> To: <> Sent: Saturday, September 14, 2002 12:19 PM Subject: Re: [BasicX] need some ideas > From: "Wolfe Digital Systems, Inc." <> > > > I am building an autonomouse aircraft for a school project; I need > > pitch and roll sensors.

Timber, The Tonkin CG-16D might work(about $30-40??).

Hi! I built an autonomous Roswell / DraganFlyer type helicopter using a relatively inexpensive 2 axis fluid filled electrolytic tilt sensor: www.rctoys.com/draganflyer3.php www.sensorsmag.com/articles/0500/120/main.shtml www.spectronsensors.com Because I used a BX24 as the "brains", I refer to this class of helicopter as a "BXFlyer". And, if you appreciate subtle humor, I named my helicopter "Nisus". However, if you want to build your own IMU, I'd suggest a Tokin or Murata rate gyro paired with an ADXL202 - one pair for each axis that you plan to control. Unfortunately, this is an order of magnitude or more more difficult: www.nec-tokinamerica.com/newproducts.html http://products.analog.com/products/info.asp?product=ADXL202 http://user.cs.tu-berlin.de/~remuss/marvin.html Or, as Frank suggested, you could shell out the money to buy an IMU "off the shelf". Taking into consideration the time that'll save you "reinventing the wheel", it could be well worth the expense! www.xbow.com Anyway, good luck with your project!! Bruce.

Hi, If one is looking for a source to build and fully understand "fully autonomus" helicopter flight check out: http://autopilot.sourceforge.net/ What they are doing and making available as an "Open System" (free code) is outstanding. Here are some of tech. they are using: gyro's; accelermeters; analog filters; compass; GPS; Kalman filters; PID algorithms; IMU; INS; and AHRS; etc.. Their archive list can be found from that page. There are some true experts in thier fields on that list! They are using an AVR processor for data collection and servo control but not what the BX24 is based on. I started to try and do what DR. Weimer did, but once I found the group. I slowed down a bit. Mark --- "Bruce J.
