I did the update of Bios but does not work .. I read a little bit that the down-face camera was designed for odemetry purposes but at the same time can be used as an optical flow sensor. I saw a page from instructables.com where they put an PX4flow sensor instead of use the intel RTF one. I will like to know if you can give me a feedback.

Thaks so much.

Hi Betancourt91,

 

 

Thank you for your interest in the Intel Aero drone.

 

Could you give me more details? Which guide are you following?

 

What sensor are you using?

Hi Alexandra,

Thank you for answering asap.

I am using the Aero RTF who use a down-faced camera (https://github.com/intel-aero/aero-optical-flow GitHub - intel-aero/aero-optical-flow ). Concerning to the range sensor, I am using LeddarOne sensor ( https://docs.px4.io/en/flight_controller/intel_aero.html https://docs.px4.io/en/flight_controller/intel_aero.html )

and I update the firmware of px4 and installed the dirver for LeddarOne following (https://docs.px4.io/en/sensor/leddar_one.html https://docs.px4.io/en/sensor/leddar_one.html ). But I did get it.

As I told you, I read from https://www.instructables.com/id/Intel-Aero-Drone-Altitude-and-Position-Hold-Using-/ Intel Aero Drone - Altitude and Position Hold Using PX4Flow: 11 Steps (with Pictures) with another optical sensor and As the video shownm they success to fly in altitude and hold position.

I hope this can help you to have an idea what I talked about it.

Best regards,

Julio

Hi Betancourt91,

 

 

Could you make sure you are booting into the right kernel? it should be this one:Linux frelon 4.4.76-aero-1.2 # 1 SMP PREEMPT Mon Nov 6 19:42:57 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Please also make sure the sensor is connected correctly and the parameters are set, and SENS_EN_LEDDAR1 is enabled

Hello Alexandra,

Yes of course I did that. Attached you will find the pictures concerning your questions. With respect the distance sensor, there is another way to check if is working ?

Thanks for your help,

Usually you can find the distance_sensor value in the Mavlink inspector under "current". I've had issues with this exact setup for the last couple weeks and I ended up having to revert back to PX4 1.7.0 and using the maxbotics sonar onboard the px4flow instead. If you find a way to get it working using px4 1.8.0 with the px4flow or even just the downward facing camera, I'd like to hear about it. Good luck.

Hi Tim Chang,

Thanks so much for your answer,

well I suppose it's working cause I have data from him. I will continue trying with the downward facing camera if not I guess I will try this tutorial; They talk about the px4flow sensor you can check it : https://www.instructables.com/id/Intel-Aero-Drone-Altitude-and-Position-Hold-Using-/ Intel Aero Drone - Altitude and Position Hold Using PX4Flow: 11 Steps (with Pictures)
