We've all been there - a rainy afternoon, bored, and need something to do. This is my effort. Trawled the parts bin and drawers for old and discarded parts to build this - my smallest and cheapest cargo delivery drone.
I normally build 2-8kg units for customers; our latest EPM-based unit is rated for 30kg. But today...it's somewhat less than this. And somewhat…
Ok, so here at last, is the autonomous payload delivery video.
Configured to use Camera trigger on RC10, and the DIGICAM actions in mission planning. Works perfectly well, but the DIGICAM command is not "rate determining"; ie the APM can…Continue
Just a post as a compliment to the Devs. Today, I was able to test a full flight with my X8 with a payload and a motor out. Only a 3kg load instead of the maximum 4.5kg, but that's a design fault of my own in the target bracket, not of the magnets or of the X8.
It flew as if nothing was wrong. Start to finish, I had full control, and it behaved almost as…
Got the "Payloader Max" out for a public demo at the weekend, and it worked well! This is it dropping a 2.5kg load in a Swisspost box. Unfortunately, the full ramp up to a 5kg load run was halted when...
The damned PM module blew! This was a supposedly a 10S unit from Hobbyking, but it blew as soon the load went…Continue
Slapped together a factory-fresh mini hex with HK APM mini + 3DR ublox, balanced the props, fired it up in the air and ran autotune, in a breezy day. Over tuned with the factory settings, but flying ok now - just needs a tweak here and there.
This is the result. Needs bit of D I think, to stablise it a bit. Maybe more aggressive control in pitch to…
So, the first payloader max is built - time for testing!
Just got the APM to put back onto the lifter, and away we go.
Payloader max: 5kg capacity via parrallel EPM's, no moving parts to fail, full autonomous integration with arducopter 3.2.
The foldable lifter (around 11-12kg lift, depending on how you mark the efficiency loss of…Continue
Not a huge post today, but thought I'd show off the new build. Still got to tune it a bit, but runs pretty tight already. But here are a few simple mods you can make to improve your 2014 quad, that are really easy to do, yet will significantly improve performance. And if you're into aesthetics, it still looks completely standard. Unfortunately, it won't decrease…Continue
Given the popularity of the 230/250 quads at the moment (blackout etc), I thought - wouldn't it be cool to have a rig that can do the ground skimming proximity stuff, but also with the normal "mod cons" of the APM?
Traditionally though, an APM would never fit. Until HK released the mini...so I built one.
I started with the Haldey-Bocks 230…Continue
Hi all. Been a while since I posted, but thought I'd give a bit of an insight into what I'm doing with "Terence" - my medium lift/endurance quad. And today is as good a day as any, as I got the latest CF samples in. And it's partly it's the start of the build instructions for when it goes live So lets build...
Part one is the main…
Just a bit of a monologue about what I did on my maiden, and I what I looked for before I started flying it properly. Some people just go full sticks right after arming, but I prefer a more cautious approach.
Step 1: All the calibrations done - radio, compass, compassmot, flight modes etc. Importantly, only 3 flight modes configured - stabilise, alt hold and Loiter.…
At last, I was able to get the payloader into the field today! A good day for it too - moderate breeze, so a good test of 3.1.2 loiter as well. It flew great - the hex barely even noticed the weight, and Nicadrones magnet worked perfectly with a sub kilo load - was able to sling it about no problem.
So spent a couple of packs doing practise runs…Continue
My second flight with the hex, after a maiden inc autotune*. It's my workhorse, and it's back to work! No real issues, apparent from a faulty AR8000 rx which seems to generating some CH3 "blips" if CH8 is connected. Weird...
This is a very dark night (no moon, full cloud coverage), so I figured a perfect time to see how my stabilised spotlight performs. And it…Continue
First - apologies for the poor video. I'm running a $30 gimbal on a standard Martinez without tuning, and a TBS with a mysterious vibe problem. I've left prop sound in, so you can hear the motors misbehaving.
Ok, my previous forays into autotuning have not had great results; today was better.
I ran autotune on my testbed, and it was…Continue
Hot behind CT's announcement of the Electro/magnet v2, my payloader is almost ready for it.
But as usual, there are problems. Some mine...some with the CF supplier.
1. The search light boom is too weak. My fault. It's only 2mm CF, and the light weights 100g. It bounces, way too much, even on the the bench. I dread what it'll be like in the air. And as a…Continue
Just a short post/update today on Terence - I've eventually found some legs I'm happy with! Yay, at last! Not the most elegant, and looks positively sinister from some angles (see above), but there we go.
Got these from quadframe, and the only fault I can find is that each clamp only clamps the leg once, and the leg angle is adjustable. I'd have…Continue
An interesting day at the field today...
Took off after preflgiht checks, and eveything was looking ok. Hovering at around 40%, looked slightly twitchy - probably because the PID's were at default, and I was about to Autotune them into oblivion, so no biggie. Gave it a bit of gas to test motor aligment, and woooahhh - massive lurch to motor 2.…Continue
Basically, I thought I'd blog my latest build, to see if it offers the community any helpful ideas.
I approached this build with a couple of objectives - to build a test bed for arducopter features and new releases, to clear down some of the parts bin and older parts.
Now a parts bin special is nothing fancy, but there are a few important…Continue
Both bird were flying fine on 3.0.1. There have been no physical changes. The Disco even flew ok on 3.1, pre-autotune, although I still can't seem to find the source of the vibes.
The Disco started autotune no…Continue
The legs are Tarot's off the shelf, but seem to perform ok. The shape of the frame means they are toe-out, but this aids video clearance anyway, so may leave them as is.
Got the rest of the…Continue
Just a heads up: Github was attacked last night, and a number of account details lifted. If you have an account there, check your security history for failed logons. I'd recommend reset your password to something strong as a precaution anyway.
