About Me:
I am a graduate student in ASU and I will start my research on UAV. We are going to build a quadrotor testbed based on arducopter.
Please tell us a bit about your UAV interest

"Great job! By the way: can I know which version of MAVLINK does it use? Mavlink 0.9 or mavlink 1.0? Thank you"
Hi Everyone: I was writing a C code to read telemetry data from the arducopter. The below is my code. It is receiving data from the arducopter, because the line "printf("%02x ", (unsigned char)temp);" does print some hex data and the data is the…
Hi everyone: We know we can send WP command to the arducopter in real time. I wonder if I can send velocity command to it? For example, we send the command "move to the right at 1m/s (vx=1m/s)" or "move forward at 0.5m/s (vy=0.5m/s)". (Maybe…
Hi Everyone: The mission I want to plan is like the followings: once I switch Auto on,1. the arducopter will fly to the waypoint1 (33.420526,-111.9252348)2. the arducopter will loiter at WP1 for 5 secs3. after that the arducpter will fly to…
Hi Everyone: I use a MB 1200 sonar for my arducopter. I test the sonar in CLI mode. But I observed that the sonar reading is always around 608cm when I put the arducopter on the table. After that I detach the sonar from the arducopter but…
Hi everyone: Today I got a new apm and imu sheild. But I found that APM output voltage is 4.6v while input is 5.0v. What may be the problem? I appreciate any help. Thanks Yucong
Hi All: I had a strange problem. Today I connected the APM to RC, PDB, sonar, xbee as usual ( I am sure in the correct way). I found when I pluged in the battery those blue and red leds were only on for a short time and off after that the apm…
Hi All: For example, I want to swap the output of ch4 and ch7 so that I can use ch7 as ch4 and leave ch4 unused currently. Is that possible? Thank you in advance Yucong
I found one of my motors is always beeping ( the one connected to ch4 output, I did ESC and radio input calibration).Then I measure the voltage of ch4 and chs 1,2,3 with transmitter off.I found the voltage of ch4 is 1.7 volt lower than ch1,2,3. Is…
I got such datalog display in the mission planner, which is wired. I tried to display the highlighted column but only two long and strong bees came from my laptop. I used 2.49 firmware and 0.87 ground station. The log data is of tlog format. I…
Hi All: I am able to connect the arducopter and groundstation with xbee telemetry. But when I put the switch in CLI mode and use terminal of groundstation. I says " error reading com port" and sth else. Did anyone come across similar situation?…
Hi All: I am the newbie and here again. This time I have an Xbee connection failure. I use xbee pro 900 wire antenna and an adafruit adapter board on the arducopter side, along with an xbee Pro 900 RPSMA. I setup the Xbee modules according to…
Hi All: I am a newbie and building my first arducopter. I connected receiver to the APM and the APM to the power distribution board as in the wiki. No matter how I move the transmitter's stick, there is no response from the motors. There…
Hi Everyone: I am a newbie. I am using a turnigy 9x transmitter and receiver. I tried to set up my radio of my arducopter. I came to radio input of APM setup. I moved my rc sticks but found: when I moved the stick assigned to roll. The…
