Mike Henderson replied to Randall Tyson's discussion Use of sonar sensor for obstacle navigation
"Yes, we regularly fly a heavily modified TBS Discover Pro to inspect some support brackets high up inside a large power station boiler.
The sonar proves to be very accurate and reliable. Mostly the Quad is flown manually with the distances all…"

Mike Henderson commented on Sergio Reyes Sánchez's blog post Teleoperating an Hexacopter
"I did some work on a prototype Quad with Sonar just over a year ago for collision avoidance in an inside environment. Interesting to see your comments on noise from the motors. 
If you're using the an Analogue Voltage signal from the Sonar Sensor…"

Mike Henderson replied to Chandruth's discussion Pixhawk Collision Avoidance
"If you have a spare receiver channel dedicated to the Retracts, then you can just read the PWM signal into the Uno, decode it and act on a value. If you're using PPM like I am between the Receiver and Flight Controller, and want to get at one of the…"

Mike Henderson replied to Kristian's discussion Almost got killed in the office today. Log file attached..
"They have, its called a 2A fuse with a connector at either end. Or use some cheap non rechargeable AA cells, that works just fine if you buy the really cheap ones that cant supply any current :-)"

Mike Henderson replied to Randy's discussion figuring out the Antenna Tracker
"Thats what I did with mine initially./

First 3D fix it sees on startup with more than 8 sats it records as Tracker Base, I have a menu option to reset it if it doesn't look right, Height was sometimes a bit off. Just needed to make sure the…"

Mike Henderson replied to Randy's discussion figuring out the Antenna Tracker
"Actually, in my home made tracker I fitted a a tilt compensated compass. I can just drop the unit down anywhere :-)

I can pick up the base unit while its busy tracking :-)





Built and programmed in about a week. Its a bit rough but it works. Got…"

Mike Henderson replied to Bravo Sierra 80's discussion What are end points?
"End points are the initial settings in the radio that you program to give the desired maximum travel of each servo or channel.

Dual rates switches then gives you the ability to choose between what could be described as 'virtual end-points". Say you…"

I thought it best to ask here before I go fitting a second air unit.I'd like to fit two 3DR 433 radios to a single Quad.Would these interfere with each other being in close proximity? cheersMike

Mike Henderson replied to Randall Tyson's discussion Use of sonar sensor for obstacle navigation
"I was wondering if you got anywhere with this.

I'm about to attempt to develop a multicopter for the Internal inspection of a Power Station Boiler, essentially a large dark area. I'm curious as to whether additional sonar would be a way to stop the…"

Mike Henderson replied to Andrew Tridgell's discussion ArduPlane 2.72 released
"Great work on the 2.72 release guys. I've been using the APM 2.5 in a Hexcopter for a while now, but the other weekend I put a Bixler 2 together with APM2.5, Telemetry & Airspeed Sensor. Its been effortless and loads of fun. No video downlink at the…"

I'm not far off building a Multicopter to be used as an indoor inspection tool. Where we'll be going is a huge indoor space, metal wall, very little lighting (Probably a few halogens). Most of the lighting will be provided by high intensity lighting…

I went out for a test hover today and it was just to collect so data. All I wanted was 5 minutes of RAW logs to look at. Came home, loaded up the mission planner, and connected. And it erased the logs all by itself :( I never got see them yet, Was I…

Mike Henderson replied to Andrew Chapman's discussion Jittery orientation after upgrading 2.8.1 to 2.9.1
"exactly what I was going to post this morning.

Something very similar. Just upgraded to 2.9.1 and I find that the vertical speed indication is fluctuating +/- 0.3m/s and the indicated height +/- 1,5m. This is with the quad on the bench connected in…"
