Reptile 500 at Shakawe Game reserve

We were invited to Shakawe Game reserve this weekend and the owner allowed me to take aerial videos at his beautiful farm this weekend and allowed us to see his amazing animals from a different angle.

 

They have from white springbok to black rooibok, as you also can see on the video all of the animals is in such good condition because everything on this farm is controlled to utter perfection, there is not a single area of this 800 hectare farm that is not controlled and managed to deliver the top quality animal walking around on this farm.

 

Here is their facebook page.

Iris Details: #4 Android Apps Overview

This is a video showing an overview of operating Iris via an Android tablet. Although we always have an RC transmitter in the mix, as a backup, the Android apps provide a very convenient way to maintain a telemetry and control link with the vehicle.

In the weeks ahead, we will be making some in-depth video tutorials on using all these different functions.

Since I couldn't find anyone who done this before I thought I should write a guide on how to do it.

3689546785?profile=original

As I understand it some of the Arduflyers delivered by RCTimer in 2012 and early 2013 are missing the bootloader on the ppm encoder chip, the Atmega 32u2. This makes it impossible to upgrade the firmware on the ppm encoder using USB and Flip as instructed on the wiki. You will know if the bootloader is missing if it doesn't say Atmega 2560 dfu in device manager after you have reset the 32u2 chip.

I was about to upgrade the firmware for the PPM encoder when I noticed that one my APM boards where missing the bootloader. While I was searching to buy a programmer to use to restore the bootloader I discovered that it was possible to use an Arduino as an avrisp programmer together with avrdude. I decided to give this a shot and as it turned out it worked really well. So if you are missing the bootloader on your 32u2 chip and have an Arduino laying around you don't have to buy a programmer to restore the bootloader. I used an Arduino UNO but it should work with any Arduino like the Duemilanove, Mega, Micro etc.

Download and install winavr from Sourceforge.
It will install to C:\WinAVR-20100110 and avrdude.exe will be found under the bin catalog.
Backup your avrdude.conf file and replace it with this one avrdude.conf.
The configuration file will be found under the same catalog as the avrdude.exe file.

Download the Arduino-usbdfu.hex bootloader file or build it. I downloaded it from the 2.9 branch. Place the file in the winavr bin directory.
If you don't already have the Arduino IDE installed, download and install it.
Load the ArduinoISP sketch to your Arduino.
Wire up the Arduino as instructed in the sketch. If you have a 6 pin ICSP-cable you can use the ICSP connector on the Arduino. I also added 3 leds to pins 7, 8, and 9 with a 1k resistor, for heartbeat, error and programming.
Add a 10uF capacitor between reset and GND after you have downloaded the sketch to your arduino. This is to disable the autoreset function.


Ok, your arduino is now an ISP programmer and you are now ready to flash your 32u2 chip on your APM or your 2560 chip if you would like. The manual for avrdude can be found here. I strongly suggest you read it to understand what your doing before trying this.


Connect your arduino and your APM to the computer and then connect your ICSP cable to the APM. Readup on Jabrams instructions where applicable here.


Read the fuses a couple of times to make sure you have a good connection and get the same results back every time, especially the device signature. 

avrdude -P com6 -b 19200 -c avrisp -p m32u2 -U lfuse:r:-:h -U hfuse:r:-:h -U efuse:r:-:h -U lock:r:-:h

Then flash the Arduino-usbdfu.hex to the 32u2 chip using this command:

avrdude -P com6 -b 19200 -c avrisp -p m32u2 -F -v -U flash:w:Arduino-usbdfu.hex -U efuse:w:0xF4:m -U hfuse:w:0xD9:m -U lfuse:w:0xFF:m -U lock:w:0x0F:m

Note that my arduino is on com6 and you have to change that part to whatever port yours is on.

After you have flashed the dfu hex, recycled power and use filp to flash the latest ArduPPM.hex to the 32u2 following the instructions on the wiki.

TBS Disco - APM mounting suggestion

3689546700?profile=originalHi guys,
Had a few queries regarding how I mounted my APM (mainly since I get a compassmot of 0%!). Well here it is. This will only work on side exit APM's!
Step 1:
Screw in  4 x 8mm risers in to the bottom plate, and add one sheet of moongel on top of the core (if you have no core, superglue some risers in the spot. Note: yes, that's moon gel stuck into the FPV camera slots.

3689546803?profile=original

Step 2:
Glue a 1mm fibre plate on top of the risers & two drops on the moon gel of the core. You can superglue the whole thing in place, but I chose to use 2 screws, for additional security. I use a battery tray plate from a spare set of quadframe legs.

3689546875?profile=original
Step 3:
Add you vibe solution. I've use moongel with good success, but I've decided to try out zeal corners (which i why I dismantled it)

3689546634?profile=original

Step 4:
Carefully place the APM in place. Take care to ensure nothing it binding; you don't want vibrations transmitted to the APM via the wires. Insert the battery to make sure it does not press the "out" servo leads. Also try and make sure the "in" servo cables don't torque the board too much, but this can be tricky.

3689546835?profile=original
Step 5:
Screw it all back together, but take not of the front starboard mount. This is where and how I placed the DJI riser. It's not exactly over the 4 holes - it only uses 2, This moves it outboard a few mm. Not much, but it might be this detail that separates a 0% compassmot from a 1%...

3689546961?profile=originalBUT...THERE'S A MASSIVE PROBLEM...


...take a look at where the USB port is.... You can still reach it with the standard USB cable, by pushing through the port front leg...but it's a really, really tricky, and you are in danger of pulling out a solder!

So find a USB cable with a 90' bend in it. And when you find one...let me know...before the logs fill up and I crash!

Dear Friends,

after a lot of work on Electronic and Frame we are happy to present first flight test of VRCopter complete of VR 2 Axis Gimbal .

 

In this fly we test this Copter configuration :

  • VR Copter Frame .
  • VR oring anti vibration system.
  • VR Copter Landing Gear
  • VR Gimbal Frame and Electronic for GoPro Hero 3.
  • GoPro 3 Hero Silver
  • VR Brain 4.5
  • 4 MK3639 motor
  • 4 ESC with SimonK Firmware
  • 3DR GPS
  • 3DR Telemetry KIT
  • 4 APC 12 Propeller.
  • 10 Amp 3S battery flight time around 20 min without payload until 24 min.

 

 

In this test flight I checked the behavior of the drone in different situations both at high altitude I flew about 50 m high and low altitude.
The video that is present in raw format created with the GOPRO 3 silver model you do not notice the presence of high-frequency vibrations, which were removed by introducing a special anti vibrating plate inserted between the frame of the drone and the gimbal . There are only some low-frequency vibrations due to the influence of the wind at high altitude on the mechanics of the gopro gimbal frame we're still working to improve it further.
Overall, we think that this platform can be an interesting alternative to cars like the Phantom of the DJI is that in the previous version thanks to a range of great flight almost 20 minutes.

This drone configuration will be available in DIY KIT before the end of year in the next week will be available more info about it

Monstor Rover

3689546742?profile=original

My current project: a Large rover!  I have found a cheap dis-used electric wheelchair on eBay, removed the "chair" and all of the electronics, created a power distribution system behind the battery pack based around an arduino Uno, two 8 channel relay modules, and two 15A step-down converters for 12v and 5v.

On top I have replaced the chair with a aluminum frame where most of the 'higher' level electronics reside, currently this comprises of an Arduino due, a raspberry pi, 1TB Hard drive, a pair of 25A motor controllers, a uBlox GPS, a network hub, WiFi bridge and a USB Hub.

The plan is to use the Arduino DUE as the brains for the motor drive, it's managing the navigation and drive of both motors.  I plan to base the navigation around the 9DOF sensor pack I have added as a primary source of information, corrected by GPS & barometer for altitude.  I have a set of SR04 ultrasonic sensors that will provide a 'distance' measurement for navigation as well.

Once the basics have been sorted (ie navigation & drive) I have plans to interface the rover into a Kinect sensor; I have begun work on this already, however I require a fairly powerful computer for the image processing if I want to do 3D point cloud, navigation (damn hard), and person recognition as security for commands (nearly done).

For now, I just thought that I would share...

Another " Multi Button Mode Switch"

At this point, more theoretical than practical.

Most TX's use 5V technology, Microchip has a nice 8PDIP, 10K, 256 step, device, the MCP41010, that will happily run on 5V.

If this were to replace a slider or pot on a TX, you would be able to hack any brand TX, even with limited tech skills.

So, this is an attempt http://youtu.be/20tISVKXImE

And the code is here, just begs to be trimmed down by a qualified code monkey :-)

Hope to have some PCB layout this week........

Tragic RC Helicopter Death in Brooklyn Park

3689546549?profile=original

This picture is a frame from a prior FPV flight conducted (safely) by the victim.

http://blogs.wsj.com/metropolis/2013/09/05/remote-control-helicopter-kills-man-in-brooklyn/

A 19-year-old model helicopter enthusiast was killed Thursday when a toy helicopter he was flying struck him in the head, a law-enforcement official said.

This is really sad. I cannot fathom being the father standing next to him.

Pilot culture can appear slightly morbid from the outside. We tend to reflect on and rehash accidents more than non-pilots. I think reflections like this are good for safety culture in amateur UAVs too.

I recently constructed carbon/XPS blade-guards for my 20 lb hex... Sometimes during the tedious machining I doubted it was worth the time.

Some may cite the kinetic energy danger in a helicopter rotor vs. multicopters, but the longer you fly, the more likely it is you'll know someone who's had an accident on a multirotor. The more accidents we have, the more we promote the "drones are usually dangerous" misconception. Consider: this WSJ article has a QAV500 FPV video as it's lead media. Concepts distinct to you and I will be conflated by the public.

Let this incident scare you, and be careful.

Sony Releases Stand-Alone Imager

specs.jpg?v=2471

Less than one month ago I predicted that eventually DSLR's as we know them will disappear, and instead you will buy lenses with the imaging chip (CMOS) built right in to the back of the lens.  Then you will only attach a simple body to it that gives you IO and a viewing monitor.  This is because CMOS chips are constantly coming down in price, but the really important part, the glass, will always be expensive.

This is an interesting idea for us because it will allow us to lift only the imager section, without carrying the weight of the DLSR body, which will cut in half the weight of a quality imager.

Well, it is already starting.  Sony have just released the QX10 and the QX100.  Both are basically intended as high(er) quality imagers, for use with your existing smart phone. They sort of clip on front of the phone, and you use the smart phone as the IO system.  They can apparently operate independently as well.

The QX100 is particularly interesting, because it weighs only 179g, but gives you a 1" CMOS chip, along with some decent quality glass.  Pretty amazing.  You can imagine building a nice little brushless gimbal around this thing and have a pretty nice setup for only about twice the weight of a GoPro.

However, I must say that I am quite disappointed in some of the specs.  Sony seem to have dumbed down performance, particularly video, as it's only capable of 1440x1080 at 30 FPS whereas the RX100 which uses the same chip can do 1920x1080 at 60FPS.

But still, this is a very interesting development for aerial photography.

Otherwise, I imagine this will be a market flop as it doesn't really make a lot of sense.  It's 2/3rd's the price of an RX100, but doesn't have the same performance or features (limited manual control). Every time you want to use it, you have to pull it out of your pocket, attach it to your camera, flip to the camera app...  Meanwhile somebody with a stand alone camera could have turned it on and snapped several pics already.

DSCQX10B_1.png

Maybe the QX10 is actually a more interesting candidate for aerial photography.  The lens and imager on this is the same as Sony's mid-range point and shoots.  In reality, the image quality is quite good.  And at 105g, it's only slightly heavier than a GoPro.  You could mount this on any tiny quad, and get pretty good photos and video. (no GoPro fisheye!!!).  It also has optical image stabilization.  

I'm not sure this will be a home run product either.  But both units are signs of more interesting things to come in this market.

3689546552?profile=originalThe above picture shows PX4 Airspeed (in fact its so new this is even a picture of a (proven) prototype), a small, digital airspeed sensor. If features a Measurement Specialties (coincidentally swiss, too) 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h). Its resolution of 0.84 Pa is quite good, and delivered as 14 bit data from a 24 bit delta-sigma ADC. It also measures temperature to allow to calculate true airspeed from indicated airspeed using the MS5611 static pressure sensor on Pixhawk. As the temperature is not influenced by the heat of nearby processing components, it is much closer to the air temperature than with the previous analog sensor setup. It comes with M3 / 6-32 mounting holes. It is supported on all PX4 autopilot generation boards (and in the PX4 flight stack as well as on APM on PX4). Andrew Tridgell has intensively test flown the sensor and will share his experience soon.

This is just the fanciest peripheral, but maybe not the most popular one: The high-brightness multicolor led featured inside PX4 is also available as external option, and it is even supported by the APM 2.x boards.

3689546525?profile=originalLast but not least a peripheral only available for Pixhawk and simple yet convenient: An USB port extender, which allows to mount the micro USB port outside of the fuselage / shell. In contrast to normal USB extenders this one is for DF13 plugs and thus does not require the enormous radius of a normal USB cable in the fuselage.

3689546394?profile=original

All these peripherals are intended to improve the ease of use and robustness when working with a PX4 based system, and will be available shortly.

"UAVs a hot topic at InfoAg 2013"

3689546385?profile=original

A good round-up from PrecisionAg.com of all the UAV companies that were demonstrating at this big agricultural technology show this week. (3DR will have a large presence there next year)

With the Federal Aviation Administration expected to open U.S. air space for the commercial use of unmanned aerial vehicles (UAVs) by 2015, a growing interest in this emerging technology has developed in the agriculture industry. This enthusiasm was on display at the InfoAg Conference in Springfield, IL, where five exhibitors (and one association) were on hand to answer questions and discuss their offerings with attendees.

3DR GPS+mag back in stock!

3689546477?profile=originalVery pleased to announce that the 3DR GPS+mag module, which ran out of stock way too soon after we announced more than a month ago, is back in stock. Any remaining backorders are now being filled, and any product waiting for this should also be going out now. Thanks everyone for your patience on this one -- a combination of overwhelming demand along with supplier problems from the resin provider (the GPS uses a special translucent gray plastic) to the pad printer contributed to the long backlog (we've taken steps to ensure that it doesn't happen again.)

If you've been waiting to convert your APM 2.5 to an external mag for superior copter performance (instructions for doing that are here), this is your chance. It's also the standard for APM 2.6, which is designed from the start for an external magnetometer. I've converted all my copters to this and loiters/navigation have never been better.

Using Drones to Protect Human Rights

3689546455?profile=original

 

Some of you may enjoy the most recent Drone U podcast about how drones could be be used to protect communities around the world that are at risk from genocide or other mass atrocities. The write up on Slate, copied below, won't be anything people on this site haven't heard before, but the speaker in the podcast goes into much greater detail that may be of interest. At the end of the talk, Sentinel Project Executive Director Christopher Tuckwood asks for our community's help with implementing his suggested program. Hopefully the embed code for the podcast will display correctly below.

 

Drone U Podcast: Can Drones Help Safeguard Human Rights?

 

Every Wednesday on Future Tense, we will highlight a talk from a leading thinker from Drone U speaking on the topic of what our drone future may look like. Drone U is produced in cooperation with the New America Foundation. (Future Tense is a partnership of Slate, the New America Foundation, and Arizona State University.) 

 

This week Drone U features Sentinel Project Executive Director Christopher Tuckwoodspeaking about using drones to protect human rights. Christopher sees this as a time of opportunity for applying new technology to the challenge of preventing mass atrocities, which is the focus of the Sentinel Project. Theories for predicting when and where mass atrocities will take place have been in place for many years, but only recently has the technology become available to gather the data needed to develop models for early warning that can help communities protect themselves.

Over the last 10 years, drones have gone from being the exclusive preserve of militaries and intelligence agencies to being available, relatively affordably, for commercial and nonprofit entities. There is also a growing talent pool of professionals and advanced hobbyists around the world that can be tapped into to help adapt this technology for socially beneficial uses. Anti-poaching applications have gained a lot of attention recently with Google providing millions of dollars to the World Wildlife Fund to help them use drones to protect endangered species. The Sentinel Project is betting that similar efforts can be undertaken to use drones to protect endangered people.

In fact, the biggest challenges for applying drone technology to human rights protection will probably not be the technical ones. Christopher notes that Sentinel Project staff consider what they call the "10/90 rule" whenever they work with a new technology. In designing programs the technology usually represents just 10 percent of the challenge, with the rest being social, ethical, logistical, and human behavioral challenges.

In the eyes of many people, drones remain a potent symbol of human rights abuses committed by governments around the world. In his podcast, Christopher lays out an intriguing alternative vision for how this cutting edge technology can be put in the hands of endangered communities to help them protect themselves against outside groups that seek to abuse them.

Join us on Sept. 11 for the next episode from Drone U, featuring David Kilcullen, CEO of Caerus Associates and author of The Accidental Guerrilla.  He will be speaking about drones and counterinsurgency.
