You need to get beyond the glossy brochure, else you are destined to be mugged.
Umm... maybe the modern 32-bit processor, instead of the 15 year old design the APM uses, or the orders of magnitude greater processing power?
ARM cortex based processors are where everything is going. No doubt about that, 3DR has already said they're switching over for the next version. You can have one now or you can wait a few years until the APM3 comes out.
The APM3 in a nice neat package with a processional looking case is what I am waiting for. Sort of a super version of the APM 2.5+ would be perfect. I expect that 3DR is working on the design right now. It would be perfect if it had the same footprint as the current APM. It would be nice if 3DR would give us a hint about future APM 3 plans.
Actually I am super happy with my APM 2.5+ so I have no motivation to change at this time.
This is an open source, open hardware project. Why not design your own case and publish the design file? You can get plastic 3D printed pretty cheap these days from companies like Shapeways or many others.
Hi Jake - I can't see how the 32bit powerful processor translate into a better controller? If it is flying, it's flying.
If someone manages to create an Ardupilot compatible quad core 1ghz 64bit processor - does that mean it's a better autopilot than the PX4?
The Ardu* with PX4 seems very lightly documented and used, while the APM 2.5 is very mature and easy to get started with.
I have 3 APMs and am about to buy a 4th, so I'm at the same junction but like Mike I don't understand the need for the PX4, to be honest.
obstacle avoidance, enough power to collect any logs possible for example.
high resolution optical flow processing for precise movement
ability to run 2 instances of code concurrently for failsafe
"ability to run 2 instances of code concurrently for failsafe"
That seems great if we can also double on hardware failsafe.
As for optical flow, it still seems amazingly limited in height and types of ground you are flying, so maybe in a room that has 10 ft ceilings and you are flying over a carpet it will work great... for what I have no idea (yet) and also includes the painfully crazy sonar. Outside missions seem tenable at best. Obstacle avoidance too seems far far away, let's see and remain hopeful!
How about folowing mode, when aircraft recognize you for example by IR beacon or your clothing color.
More important thing for the moment is motor feedback. When controller really know how fast your motor spinning and how much amps each motor draw in the moment. It is crucial when we speak to failsafe. Hexacopter can change its mode to tricopter in case of one motor failure or increase speed on ramaining motors.
The posibilities are endless, it is only question of processing power and ability to realise it in code.
git clone https://github.com/PX4/Firmware.git
There is something in there on running completely different operating systems on the same chip, one on each core.
Would be great if 3drobotics was putting their professional coders on exploring stuff like that instead of re-inventing the wheel as a heckaflexihexigon.
The PX4 software is a product of 5 years of development & is light years ahead of the APM which is neither very mature nor easy to get started with according to many posts on this forum.
"If someone manages to create an Ardupilot compatible quad core 1ghz 64bit processor - does that mean it's a better autopilot than the PX4?"
Yes, the more processing power, the better tuning of the sensor biases & fusion. The APM doesn't have the power for this. Nor does it have the power as was said above to handle things such as obstacle avoidance & vision techniques.
If you want something that works out of the box, don't like to participate in open source projects, & don't care about getting the best performance, you're better off with a Dji which already has excellent performance for what it is.
There are always exceptions to the rule. Our present ArduRover2 v2.20b code has very good obstacle avoidance capabilites using the Sharp IR sensors. It works well and I have verified its performance on my 6WD rover. In the final update of the original JLN ArduRover2 code we plan to offer the ability to select several different Sharp IR sensors for medium to long range obstacle avoidance.
Just a thougth.
