Alejandro Martin Pirola commented on Chris Anderson's blog post Using ROS Gazebo simulator with ArduCopter
"Patrick, Aurelien thank you for sharing your setups. I will try one more time from scratch using Aurelien's scripts.
Tell you later."

"Seems like alexbuyval's mav_comm version is different from https://github.com/ethz-asl/mav_comm
Mar 19 they renamed CommandTrajectory to CommandTrajectoryPositionYaw at pull #14

"I did fix missing planning_msgs removing both refrences from rotors_simulator/rotors_gazebo_plugins/CMakeLists.txt
seems those reference were not needed.

Now catkin_male runs up to 73% then compilation FAILS, error message:…"

Alejandro Martin Pirola commented on Chris Anderson's blog post Using ROS Gazebo simulator with ArduCopter
"Great!  But...
I went through the whole setup process and fail. I did a bunch of steps more than wiki has.  
First, don't try to setup Gazebo in a VirtualBox, make your life easy and do it in a native Ubuntu 14.04 installation. VM adds a lot of GPU…"

Alejandro Martin Pirola commented on Thomas J Coyle III's blog post Two airliners have 100-foot near miss with drone above New York
"Pilots also see UFOs and no one is making a law regulating UFOs. Come on... this guys can see eye naked a flat (under 1m diameter) static object  in the air passing by at 400 km/h??
I can barely see my Tarot 680 at 250 meters away with a perfect…"

Alejandro Martin Pirola commented on Chris Anderson's blog post Gumstix releases new APM/PX4-based Linux autopilot board
"I need some help. Correct me if I'm wrong, AeroCore 2 is just another Pixhawk like piece of hardware (able to run APM or PX4 stack) and Overo COM (able to run ROS or another linux based OS) interacts with AeroCore 2 through UART and SPI ports, which…"

Alejandro Martin Pirola commented on Adrián Nagy Hinst's blog post GimBALL - 3D printed DIY Gimbal with closed hull - PART1 (design)
"Nice design, a bit complex for a low cost FDM 3D printer, It seems to be made for a much more expensive SLS/SLA 3D Printer."

"Sandy, I have the same issue, glad to know you documented it so good. Despite Bad Baro... messages, baro seems to work fine. "

Alejandro Martin Pirola commented on Chris Norris's blog post seL4 Secure Micro kernel
"Agree with Chris Norris, NICTA seems to be an attempt to protect against Kernel attacks and maybe a set of User space tools to react. Any other kind of attack remains being a threat."

Alejandro Martin Pirola replied to Drone-University.com's discussion Can anyone explain those new designs ? Purely aesthetics or indeed more efficient ? in ArduPlane User Group
"I think it may be a modular design, a "divide and conquer" approach. UAV frame and propulsion simplified, then payload is an extension connected in a fancy way. A extremely low center of gravity ensure stability. CoG is so far from wings, ailerons…"

Alejandro Martin Pirola commented on Laird Foret's blog post CHEAP LIDAR!
"Would be nice get LiDAR data stream and full fill it with IMU data such as pitch and roll + Sonar Range Sensor for Alt. in order to get a full 360 degree x ~45 vertical aperture point cloud, taking advantage of multicopters pitch & roll balancing."

Alejandro Martin Pirola commented on Laird Foret's blog post CHEAP LIDAR!
"Laird, please don't get me wrong, I'm glad your team build this LiDAR almost RTF. Actually I was waiting for something like this. XV-11 LiDAR units are great, but requires a lot of work get this things working out properly. Cheers

Alejandro Martin Pirola commented on CSGShop's blog post Full SPI 11DOF IMU with GPS...
"Nice work CSGShop, tell us about which MCU do you have? And I would like to know about your base firmware, which AHRS or fusion sensors algorithm are you using DCM, Kalman? SPI ouputs includes Raw data and AHRS Quaternion?"

Alejandro Martin Pirola replied to Alexey Kozin's discussion arduplane 2.76 ahrs level correction problem in ArduPlane User Group
"I found that if you increase AHRS_RP_P param from 0.1 to 0.4 (means ACC more weight in attitude estimation than gyros) mitigates this issue. With AHRS_RP_P = 0.1 APM went out of control during a long 28 degree turn, now in 0.4 I can take long turns…"
