FS: Robota Goose Autopilot (brand new)

Started yesterday 0 Replies

Selling 1 brand new Robota Goose autopilot system. I was going to integrate this into multiple AP rigs but decided to stick with the APM 2.5 system. Comes with all cables, u-Blox GPS and hookup for…Continue

Failsafe Problems with Spektrum DX8 and AR8000

Started this discussion. Last reply by Michael Pursifull Sep 11, 2011. 6 Replies

I just had a completely lousy crash yesterday in the middle of a very successful flight... My setup has an externally powered 1W Xbee Xtend, so the range on the GCS is farther than the Spektrum…Continue

Max power through telemetry port on APM

Started this discussion. Last reply by John Cousins Jan 1, 2012. 6 Replies

I recently added the Xbee Xtend 900 to the APM. Prior to that with the Xbee Pro 900, everything was OK aside from poor range with the unit. I believe that two recent crashes involved a brownout on…Continue

Skywalker Defaults yield odd tracks

Started this discussion. Last reply by Trent Aug 26, 2011. 1 Reply

I've been flying with the APM for months, and until a week ago, didn't have any troubles. Last week I had a plane go down in the woods after issuing a guided mode command "fly to here". I wasn't able…Continue

FS: Robota Goose Autopilot (brand new)

Selling 1 brand new Robota Goose autopilot system. I was going to integrate this into multiple AP rigs but decided to stick with the APM 2.5 system. Comes with all cables, u-Blox GPS and hookup for Spektrum receivers. I also have the software with license keys that will be provided separately. Will consider all best offers. Paid $1,889.21 for the unit.See More

"Then you missed the gist of my posts. UDP is a bad choice for bi-directional command and control data. It creates unnecessary complex overhead on a system that already has limited resources. Use the right tool for the task at hand. UDP for…"

"Blake : exactly - I basically wrote the same xx posts earlier, when I suddenly needed to "defend" UDP  when it got described as a useless choice. "

Blake Turner replied to Avalerion's discussion Dronecell Integration Needed ASAP - $1000 prize
"Andke, UDP packet management would be the responsibility of the APM, specifically when attempting to use UDP for bi-directional comms, which is where I was referring to overhead. TCP stream management, in this case, is done by the DroneCell, hence…"

Andke replied to Avalerion's discussion Dronecell Integration Needed ASAP - $1000 prize
"regarding microcontroller overhead, and some of the comments here - remember that I do transparent connections, once the GSM module is initialised - it seems transparent - APM does not need to spend more time on it other than the config after boot."

Richard replied to Avalerion's discussion Dronecell Integration Needed ASAP - $1000 prize
"I agree with Paul and Blake... As it stands, the only real benefit for this dronecell is the fact that you can indeed connect it to UDP or TCP/IP and the like... The only other benefit is that you can use dronecell with a network via towers on a GMS…"

Blake Turner replied to Avalerion's discussion Dronecell Integration Needed ASAP - $1000 prize
"Hence my comment regards overhead. In my honest opinion, while you can do some really funky stuff with the DroneCell integration, I think its intended purpose was primarily as a telemetry channel, not a control channel. If you want proper GSM based…"

"ok - I just solved the TCP "challenge" TCP connection is not a problem - Dronecell boots, commands gets it's IP - IP is SMS'ed to my cellphone - I enter it into GCS and connect to it. drawback by connecting TO dronecell; …"

"For telemetry it should work fine. I would not recommend uploading any missions or changing any parameters. I also don't know if the planner or qGroundControl request all the info on startup. I know my GCS does with APM. This would be bad…"

Andke replied to Avalerion's discussion Dronecell Integration Needed ASAP - $1000 prize
"ok, for my part - telemetry is main goal for now, - I also know that reliable communication can be done over UDP - provided that we have software to verify/retry when needed. "
Feb 27, 2012
Blake Turner replied to Avalerion's discussion Dronecell Integration Needed ASAP - $1000 prize
"Having extensive experience developing communication and telemetry systems on cellular technology, I would agree with Paul. Simply put, if you want _reliable_ bi-directional comms, TCP is your answer. If you are only interested in a telemetry…"
