Michael Duffy replied to Steve's discussion MAVLINK to MATLAB?"Xbee's are used to stream the data to the ground station. Not sure of the bandwidth requirements for Arducopter data yet, working on that. Any luck with your code to interface with mavlink?
Thanks,
Mike"
Criterion-Industries replied to Steve's discussion Firmware Not Uploading March 31"I know this is a slightly old thread, but I am also now having this issue. Despite selecting a com port I cannot get the board to connect. I have tried reinstalling MP to no avail. This is on a system that has been working fine. I…"
Owen McAree replied to Steve's discussion MAVLINK to MATLAB?"Hi Mike,
I am currently rewriting all of our code for this as it very much evolved beyond its initial design to the point where there were more bugs than code! I'm hoping to have something decent up and working before the end of the year which…"
Michael Duffy replied to Steve's discussion MAVLINK to MATLAB?"Owen,
I need a live stream of data to matlab or simulink so that we can process the data real time, and then send a command back to the quadrotor. We are using APM 2.0 on our aircraft. We have multiple vehicles, and will need to…"
John Lau replied to Steve's discussion MAVLINK to MATLAB?"Fantastic works! I'll try your interface, you did a meaningful work for many researchers including me! Thx~"
Owen McAree replied to Steve's discussion MAVLINK to MATLAB?"We did this last year (well to Simulink, but MATLAB would work too), but development has stalled. We're currently reworking everything to work with MAVLink v1 and support multiple instances.
What exactly is it you're trying to do, I'm…"
John Lau replied to Steve's discussion MAVLINK to MATLAB?"Any progress? I am about to do the same thing, but with no idea."
Adam Kimberlin replied to Steve's discussion MAVLINK to MATLAB?"Any luck on this? I am about to try and do the same thing."
Steve commented on DougB's blog post One way to Restore a bricked xBee"I have like 4-6 pairs of Xbees and over 70% of the units eventually stopped working properly. On some pairs i was able to perform the unbricking procedure but are stuck on a baud rate and can't be changed.
I have long moved towards the Diy…"
Jan replied to Steve's discussion APM 1.0 Randomly Stops Transmitting PWMs?? Aircraft crashes..."Steve,
In my case it was a physical connection between the mux and the 2560 µP.
There were 2 bad vias between the top and bottom of the pcb.
Regards"
Steve replied to Steve's discussion APM 1.0 Randomly Stops Transmitting PWMs?? Aircraft crashes..."Thanks for the update. Do you think this is a problem with the multiplexer or just the physical connection between the 2560 and the PL4...PL5..etc mux"
Jan replied to Steve's discussion APM 1.0 Randomly Stops Transmitting PWMs?? Aircraft crashes..."so, got the wires in place and he is airborn :-)
just did a maiden flight back in the garden and went very well.
stable and smooth flight.
tomorrow I will give it a shot with some other flight modes.
my setup:
board: apm1
esc: hobbyking 20 SS (hw)…"
Jan replied to Steve's discussion APM 1.0 Randomly Stops Transmitting PWMs?? Aircraft crashes..."Hi,
I ran into similar problems using the APM1 for my quad.Testflights showing irregular speeds for motor 1 and 2 (sudden stops, spinning up)
After a bench test yesterday output 1 & 2 just stopped working period.
I took the schematic and…"
Steve replied to Steve's discussion CCD Camera Network Downlink?"How are the performance of these units? I've experimented with 802.11n wireless already and it gives great quality video, but the frame rate can dip dramatically when there is bad interference or misalignment."
Siavash replied to Steve's discussion CCD Camera Network Downlink?"Hi Martin,
I'm looking to use the XR5 module for a high altitude flight. Have you used it yet for your video application? If so, was it successful and would you recommend the XR5, with regard to data rate and power consumption? I assume the…"

3D RoboticsAlan Sanchez said… - Hi Steve, Im really sorry the part for the chassis was defective. It just so happened that I had the same issue today when trying to put together a chassis. There must have been a bad batch somewhere along the way, because all others seem assemble perfectly.Please send an email to help@3drobotics.com with your information and exactly which part it is you need replaced and first thing on monday I will personally take care of it. Seems like you are in Cali so you should get it in no time. Again sorry this happened.
-Alan
