About Me:

Early retired Electrical Engineer with special interest in control applications


Please tell us a bit about your UAV interest

In the early days I programmed small roboters on wheels in Java. With the programming of the AR.Drone from Parrot I entered in the field of flying robots. For getting experiences I built the APM 1 on an extended tiny QuadPod kit from Snelflight, UK.

Hans Jakob Bosshard replied to Rolf Inge Sivertsen's discussion AC3.2.1 APM 2.5 Throttle pulsates in Loiter
"Another point could be worth to look at:
The INS_TC_Z value i.e. time const for baro and acceleration mixing. Lower TC decreases z acceleration (ev. with vibrations) influence on the altitude estimate.

Perhaps this value could also optimized."

Hans Jakob Bosshard replied to Rolf Inge Sivertsen's discussion AC3.2.1 APM 2.5 Throttle pulsates in Loiter
"A general remark. Perhaps the parameter INAV_TC_Z time constant which influences the weight of the baro and acceleration values in the mixing process . I had some better alt hold behaviour with the APM by changing this value."

"Hi Dominik,
I am also interested in this Meeting. I sent you a personal message yesterday to get in touch.

Best regards

Hans Jakob Bosshard commented on UnmannedTechShop.co.uk's blog post Scout X4 - Follow Me Quadcopter from Walkera
"I hope that the quality of the new Scout 4 is much better than the Walkera QR x350 pro at this price. In view of the postive remarks in this forum I bought the QR x350 pro. By delivery the GPS was defect. A replacement GPS brought not much better…"

"Hi Jean-Louis,
Just another question:
I have seen your description on the CX-20. On my side I want to build an original APM 2.6 in my Walkera QR x350 Pro, as the Walkera flight controller is not a good choice. Do you where I can get an extension for…"

"Hi noel,
I just received the ordered X 350 Pro via RCmaster. After the ordinary compass calibration I realize, that the GPS seems to have outages i.e.some time the sats nr is > 7 .. 8 (seen in the MP) and LED on the Quad and sudenly there are 0 sats…"

"Hi Noel thanks for the good clarification!
I have an offer from France with the devo 7 in mode 1. Do you know if I could alter the mode 1 to mode 2?"

"Hi Noel,
For me it is not clear, if it is possible to download the newest APM Software Version via the Mission planner as usual or not.Thanks for clarification."

Hans Jakob Bosshard commented on Roberto Navoni's blog post VR Brain Micro 5.0 : VRX Personal Fly Robot SDK the perfect fly platform for test all the feature of new VRBrain. The firwmare is tested and we are ready to start to ship the first boards next week.
"Hi Roberto,
For me it's not quite clear if I can use the same special Arduino IDE as for the Ardupilot for the VR Brain Micro.
When do you plan to sell the VRX AV250 frame for an experimental quad platform for which Price range?
Thanks for your…"

Hans Jakob Bosshard replied to Jerry Normandin's discussion Has anyone configured APM 2.0 for the QuadPOD ?
"Quadpod with ArdupilotHi all,
After some longer time to find the appropriate PID Parameters, I succeded to fly the Quadpod in a smotth manner with the APM 2 with the newest Firmware 3.1. Look at the short Youtube Video which shows a flight in the…"

"Guten Tag,
Ich habe Deinen interessanten Blog angesehen. Welche Software verwendest Du für den  Crius AIOP V2 Controller? Auch die APM Software? Für welchen Zweck dient das Bluetooth Modul?
Ich hatte mit dem APM 2 Mühe mit den PID Einstellungen,…"

"Hi, I used the older description on this site for the x-configuration (see below) which suits fine the Storm Drone configuration. I used another seperate UBEC for powering the APM http://store.jdrones.com/3Amp_5V_uBEC_Low_Noise_p/ubec3a01.htm . For…"

"Hi Mike,
I forgot to mention in my last comment that the used ESC type is also unclear for me. But they run without problems in Connection with the APM 2.
Regards
Hans Jakob"

"Hi Mike,
At this stage with the actual PID params take off is ok. Manual control could be better (sometimes small oscillation in pitch and roll. Loiter could be better (to tune). Alt hold bad with oscillations in height (sonar range) of several…"

"Hi Mike, yes, I can give you some advice for installing the APM on the Storm drone. The PID tuning for the APM 2 is not yet optimum for manual control and alt hold. I hope for better results after the long winter period with knob tuning on the DX…"

"Hi Brian,
Look at the QuadPod Kit from http://www.snelflight.co.uk/QuadPod.htm . I added a second platform to the QuadPod to have enough place for installing APM 2, XBee and GPS. I used the delivered Motors and ESCs for the rest. It flies with a…"
