This is a 3D scanner from Faro.  Spec sheet and brochure and videos can be found at the distributor web site ATS.  This is a video of the scanner on a Lego trolley, so how long until we have something this good on a quad for automated object avoidance and landing???  Engadget article can be found here.

 

How much processing power do we think it would take to use hardware of this calibre??

Saw this on the news, and then read about it today on engadget as well.  Interesting points - 50 pound chopper, to be used primarily for surveillance, but also weapons capable.  Local 2 News has a tendency to blow things out of proportion, and they clearly wanted to sensationalize this, but the technology does raise some interesting privacy issues that may need to be addressed in the long run.  Is an individual invading someones privacy if they capture video of activities that might otherwise be private??

Check out the full article over on engadget

 

The wifi backpack may prove to be cool depending on range, but the fact that they are integrating remote control, better streaming ans stills performance really shows they are listening to their customers.  SO, is this YOUR next drone-cam?

There have been multiple discussions in the threads of various ArduStation posts in the last few weeks about form, function, capabilities both in conjunction with and without a GCS or planner. I have joined in on some of those discussions and what came out of many of them is that we all have different approaches to what we want out of an ArduStation-like component. Some people want a simple mechanism to just decode the LAT/LON, calculate a direction and point the antenna. Some people want it to point the antenna and pass along the data stream via another communication protocol. Still others like having the screen and buttons to tune PIDs, etc. Some wanted the whole enchilada PLUS a touchscreen to do away with the old text screen and buttons...needless to say there was not a lot of consensus - so that got us talking and a modular format became a part of the discussion.

So what I would like to propose is a new project called the ArduStation HUB. A completely modular unit that will allow people to build upon it and add each component they require. So chime in, tell me what you think. Do we even need anything like this? Is my design brilliant? lunacy? Let's crowdsource the design and I wil get them built - if we come up with something truly awesome, perhaps we can get it added to the store.  I know MANY of you have been working on various versions of hardware / software etc.  Can we come up with the modular software to match?

Got any great ideas of how to use a flexible board Arduino - these guys are making "a few for inspiration" and sound like they are willing to share their new toys with people with awesome ideas!!

It is a neat little package, but I'm not sure it garners Engadget coverage...

http://www.engadget.com/2010/06/03/cheap-tiny-camera-for-rc-planes-captures-video-proof-when-you-b/

- I just looked at the whole thing..it just records and stores, has a USB output on the back. Might not be too bad as a pylon or external mounted recording option...records VGA at 25fps on to 2GB of internal storage.

I just thought you guys might like to know that we are still making REAL progress over in our workspace. Sarel has been working hard on his prototype and as you can see, mine is coming along as well - we should be combining all of our trials an errors soon and have final schematic and board designs soon. So who else might be willing to help out and lend us a hand programming all that graphical goodness??

A little side project...

I’ve been working on a little side project. I originally wanted a case and / or a stand for my Xbee and Xbee Explorer module, so I ordered a couple from Polycase and strapped it together. It looked nice enough and attached to the back of my laptop with Velcro so it was an OK solution. Then I started getting lazy and didn’t want to lug out my laptop and everything every time I wanted to log a flight, so I went to a couple of the different on-board loggers, but never really found a solution I liked (picky, I know.) So that brings me to my little project. I have just finished the schematic, layout and specs and I have a few boards on the way.Here’s what it is: It functions in four possible modes; logger only (you can use it as an onboard data logger without the case and additional modules,) logger plus data pass-through on the USB port (with an Xbee module attached - for when you want to log data to the microSD card AND pass it through to a PC,) stand-alone receiver / logger (with an Xbee module onboard – utilizing the onboard battery, no PC required.) So if you took the best attributes of an XBee Explorer module and combined it with a really good data logger with a battery and charger…this would be the love child.I actually have two versions: one for those of us who like elegant solutions, and another for those who believe in extreme simplicity, but require fewer features. I call them LinqLogger, basically because they were designed to log downlinked data.The first design consists of the following components and features:Components:It uses an ARM7 LPC2148 (512K user flash and a ton of GPIO pins,) includes both a USB and Barrel plug LiPO charger (MAX1555,) On/Off switch, RTC (facilitates date / time stamping of logs,) Xbee socket (pick your own or use one you already have,) external reset, and start / stop recording buttons, USB link and logging status LEDs, microSD card slot (up to 2 GB FAT 16 formatted for PILES of data)Features:Not only does it do a nice job of data logging, but it also has a USB mass storage device profile built in - so when you attach USB, you get a mounted drive on your PC where you can see the actual files on the SD card; nice because you don’t need a separate microSD card reader / writer.The external battery connector makes the board a very independent data logger; you don’t need another microcontroller. It comes with SD+USB boot loader that allows the end user to tweak firmware to their project specifications. Configuration is done through an on-board configuration file, so there is no need to type in initialization commands. When the module is switched on and logging is initiated, everything received by the Xbee module is recorded.The second (simpler) design consists of the the following components and features:Components:It uses an ATMega 328 (16MHz, 3.3v), USB LiPo Charger (No barrel plug – MAX1555, charging LED,) microSD card slot (up to 2 GB FAT 16 formatted for PILES of data,) no RTC, On/Off switch, simple FTDI to USB (just like Xbee Explorer,) Program / Log Switch (used only when programming the ATMega328 via an FTDI – this is done so that the USB used for charging and data pass-through is NOT used for programming.)Features:This model uses the basic serial STK500 boot loader which comes pre-installed so that you can tweak the firmware, but has very few additional features. The system is the equivalent of combining an OpenLog logger interfaced to an Xbee Explorer with an on-board power source and charger.If either of these sound interesting to you feel free to drop me a line. I will be posting pictures, schematics etc., and of course it will all be available as Open Source. I have breadboarded these and they both work well. The boards and the cool little cases will both be here in the coming weeks...if anyone else wants one, I'd be willing to sell them at cost as kits or something. Any ideas you guys have for additional development are obviously welcome too!

Outback Challenge - Who's up for a run??

So some time has passed, and I have a nagging in the back of my mind - why couldn't we field an Outback Challenge Team? We are already working on several projects, and combined we have a PILE of UAS time in the air. We could even purpose-design the entire system; airframe, autopilot, all of it from ongoing projects or designs here on DIYDRONES. I have no doubt we could raise a little money and could field a competitive team. I know we are spread all over the world, and that this is all OpenSource...but what better way to prove that this type of collaboration really can produce world-class results.Sooo...who's in?? Seriously, I'm in - and looking for compatriats!

Huddle Issues Anyone?

I have been trying for a while now to get into / see the Turn Rate Limiter Workspace in the Workspaces section...but it doesn't come up...I am on two teams, and can only see the Workspace for the New Ground Station Design team. Anyone else having similar issues - or did I get kicked off the team...lol ;)I have the uBlox GPS Module library part I need to upload.

Someone has GOT to remember seeing this!

SOme time back (within the last two or three months) I recall seeing a ground station setup where a guy was using a graphical LCD module similar to the one proposed for the NEW ArduStation Mega, and he had a very cool interface, even had an artificial horizon on the screen - DOES ANYONE ELSE REMEMBER SEEING THIS?? Wa it here or on some other forum??

Robust GPS Antennas (not modules)

As many of you know, I have been looking for and even doing some development on some GPS modules. I met this vendor today who makes the most robust GPS antennas I have ever seen - Quad Helix 30db gain active antenna with built in SAW and LNA you can take a hammer to it, and it will just keep on tracking - awesome! The key is the mold-over they are using, it can take a real pounding, and with an O-ring could form a weather-tight seal to the airframe. You could just mount antennas on each of your airframes and only ever buy one actual module - but seriously, I have no affiliation with them.http://www.jimdgrayassoc.com/index_files/STUBBY_PRO.htmThey are pricey, but you'd only have to replace one destroyed complete unit to justify the price. Just thought you guys might be interested. We have already placed our first order.

I have been looking around for some time for a good GPS solution that fit all of my needs, had great compatibility with other components (without a ton of work on my part) AND gave me the features / performance I have been looking for…guess what – I found very few, and when I found them they were usually out of stock! So, I decided to look into putting together my own. I have the board designed, parts sourced, and a design/ fab house on board to help me make it happen. I am waiting on a final BOM (Bill of Materials), Logic Test, and DFM review before I will know what the actual parts / production cost is – but it got me wondering, so…I am looking for feedback – trying to determine whether or not anyone would want the following, and what you’d be willing to pay for it?GPS Module Specs:Ultra High Sensitivity–148dBm (Cold Start Acquisition)–165 dBm (Navigation)Low power consumption: 75mW @ 3.3V10Hz Fix RateNMEA protocol (default speed: 9600bps)WAAS/EGNOS support22 Tracking Channel – 66 Acquisition Channels (Best in Class)Cold Start (out of the box): 34s typ.Warm Start: 33s typ.Hot Start: 1s typ.Protocol: NMEA 0183, @ 9600 baudSensitivity:Acqusition (cold):-148dBm - Re-Acquisition:-160dBm - Navigating/Tracking:-165dBmPower Drain: (3.3V): Navigating: 1 fix/s: 75mW typ. - Backup state: 15uW typ.Active Sarantel GeoHelix Quadrifilar antenna:Right-hand circular polarized, 3.3 V, 50 Ohm, SMT mounted directly to the PCB board, +25 dBic Gain and operating temp between -40 and +85 degrees C, weighing 8.4 gramsOnboard Data Logger Specs:The data logging component incorporates the LPC2148 ARM 7 Processor with USB, battery charging, and microSD support. This allows use of the OpenSource SparkFun LPC2148 USB bootloader for fast and easy modification of the datalogger firmware without using a programmer. The logger employs a USB mass storage stack to appear under any operating system as a flash drive. Logs are created in FAT16 format on the micro-SD media and can be downloaded quickly over a USB connection by dragging and dropping the text files from the device. The microSD card can also be removed and inserted into a card reader to download the logs. Board comes with a JST connector to be powered from a LiPo battery or other power sources. If you choose to use separate LiPo batteries for GPS functions, the unit has a built-in charger to charge batteries off USB. Additional pins available for logging of additional information (temp etc. with add-on boards and firmware modification,,it is OpenSource baby!)Ships with 2GD microSD card and SD Card AdapterAdditional Board-Level Specs:Board has outputs from both of the GPS antenna UARTs, and data can be found on TTL (Raw GPS data for telemetry, I2S, and a connector compatible with the output from the EM406a GPS (ArduPilot Compatible – no adapter board required) An additional output is provided for sending data to a compatible OSD system (RVOSD compatible – plug and play.) A small rechargeable battery keeps the GPS config and datum on board for quick fixes.Please keep in mind, a comparable data logger is $60 dollars (although we could go cheaper if we dumped the microSD card slot and USB connectivity, but I love the elegance of this solution) and a comparable, but lower performing UBlox GPS unit is between $90 and $100 depending on where you buy it, if you can find it.So now with all that said…what is it worth?

The Ultimate Modular Open Source Auto Pilot

I have spent a lot of time looking around at all of the different models of autopilot from the simplest Arduino implementation to the most complex solutions in the $10K range. The thing that most of these seem to lack is modularity. I'd like to see the community come together to develop a "Main Board" and then a bunch of additional add-on components that are designed to work together with the appropriate code. As an example, say I want to start out with a simple main board, thermopiles and a gps, but them later decide I don't want the thermopile anymore and I want an IMU based system, and acoustic rangefinder for auto-landing - but wait, later still I want a system with a laser rangefinder, onboard video for FPV, and I want to log the data from a bunch of the components...obviously, I'd be throwing out a lot of hardware every time I wanted to learn more or upgrade. So how about it?? Who is in? I'm kinda liking the name ModuPilot..
