dhiraj replied to Nicholas Witham's discussion Why are we starting to use companion computers? in the group Companion Computer Working Group
"IMHO there's two layers where you can tinker with drones, one is the core flight (autopilot layer) and the other one is applications which use drones for some task. Once your drone is ready to listen to your commands, what would you like it to…"

dhiraj replied to Nicholas Witham's discussion How do I decide what platform to use? in the group Companion Computer Working Group
"Hi Nicholas, I'm a developer from FlytBase team. I would suggest going for odroid, rather than Edisson, especially if you want to use computer vision onboard. Dronekit python is a good project if you want to write python scripts to control the…"

"@ Alex Wright Yes that is a STM32 processor, doing job of a conventional autopilot. It runs fork of Px4 flight stack. And talks with Odroid over serial connection. "

"That looks interesting! And seems like a lot of work, from your blog. But is it really necessary to separate out common features which you can easily get in a single packaged autopilot? Is there any special configuration required at basic autopilot…"

"@Serge Contal, the fan is not for Wifi router, its for single board computer / companion computer. Actually we also wanted to avoid putting it, but it seems inevitable given the Octacore processor at 2 GHz. Until now we haven't faced any…"

"Hi, do you really need the fan ? Does it impact the WiFi performances ? I design WiFi routers and we get rid of fans if we can (with the help of good dissipators) because they make much RF noise."

"Thanks @Jerry Giant, thats quite useful info. The hardware is closed but the access to router is open and documented here. So practically anybody can configure wifi board with any other firmware if they want. Currently it is interfaced using…"

"@Bill Bonney Yeah, I too believe that range isn't relevant. With directional high gain antennas and stuff you can increase it significantly. Our purpose of bringing this FC is not to compete with other long range solutions. FlytPOD is for…"

Bill Bonney commented on dhiraj's blog post Flight Computer with Built-in OpenWRT WiFi Router!
"Range isn't that relevant using the standard dipoles you are going to see 500m-1000m at 2.4Ghz. If you use better antenna and directional antennas you can get that up to several Km. Nice to have WiFi solution that can support Video.…"

"@naish We haven't yet done any long range test but we have very successful results within 250 meters, LOS. Soon planning on testing range between two drones with FlytPOD, beyond 500 meters."

Flight Computer with Built-in OpenWRT WiFi Router!

Posted on June 6, 2016 at 10:14am 17 Comments

Traditionally, drones have used low bandwidth radio communication to connect to ground devices. Last year, when we started building the FlytPOD Flight Computer (next generation autopilot), we wanted to equip it with a better communication system.…

Drone color marker game using Computer Vision: DIY in an hour!

Posted on March 10, 2016 at 11:48am 6 Comments

Hello Guys

Ever wished to write an intelligent script using Computer vision to play with your drone? I did. In fact yesterday I started working on some basic thing and came up with a small drone game.

Drone will climb up 1m when it detects a blue object and will climb down 1m when it detects a red object. Thats it!

It took me about an hour to…
