"I really enjoy making these. I'm on my 3rd now. My first was a lot like yours, same motors and all. It was a lot of fun. The current bot was an attempt to clean everything up like yours. unfortunately it's another rats nest…"
"Looks like a great start. Next you need to add wheel encoders so you can do more complex control of the bot for maneuvering and autonomy. I've found basic PID is not enough for rc control.
The nBot uses a very workable control…"
"It pretends to be an arducopter right now so it has all those capabilities, like joystick control, etc.
I need a few more days to get the HAL tested. I have the main loop running at full speed now and all the control code in. I just need to get the…"
"I'm thinking of making one for me, the mechanics are simpler then a rover. Can you give more details on what are your motor drivers and how they connect to APM? Is there a place I can peak at your code?
What do you think about doing…"
"I had to put it down for a few months as we switched to the HAL platform but I just picked it up again. I did have missions running a while ago:
That's all autonomous until the end of the video.
"This has happened to me 4-5 times. Usually a minor crash triggers it. The motors start to dip or pulse for a few flights, then bam it drops out of the sky. You need to remove all mechanical stress/vibration around the solder joints to prevent it,…"
"Hall effects sensors are finicky compared to optical? Oh dear....
He needs to do a basic calculation of the frame rate vs ground speed to get his answer. But I've also found the sensors are sensitive to specific wavelengths of light which…"
"Are you using I2C to chat between devices or Serial? Ardupilot uses some very nice I2C and Serial stream libraries which have been engineered to be interrupt driven and not "block" execution of high level code.
I would use these…"
jasonshort - thanks for sharing your experience. I have added lenses to the flip externally and they work ok, would you mind sharing your lens adaptation for the flip? I have been researching the ardupilot and trying to understand how it might work with our twin easystar - maybe I should just jump in and get it. thanks again for your thoughts.
Hey man wondering if you have flight tested your AIR app yet. Would love to get my hands on the source - even just the artwork, it looks amazing. Great to have another Flash dev on here to toss ideas too.
I saw a post concerning rc cars. Well, that's what I want to do but I now understand that this is more complicated than I thought due to the fact that cars move slowly and the GPS has a hard time with that. I understand that one needs other sensors like magnetometers, obstacle sensors and etc. I was wondering if you have seen a post where some nice person has listed the components used and the codes. I was kind of excited to do this but I'm starting to think that the only way would be to have someone who understands it to build it for me or walk me through it. I was thinking that an arduino controller would connect to the ardupilot and the ardupilot would connect to the RC.
I thought I would ask you if you had any suggestions on this.
Sorry I don't. I would Start with the encoder for the wheels. These usually use a hall effect sensor and a tiny magnet attached to the wheel or other rotating part. Maybe that is a hint that could lead you to some example projects.
Great to see the work in progress. I have a new APM that I bought ready assembled and programmed few months back, it was a little too unstable for my Flying Camera Mount designs that I am working on. However I have just uploaded the latest code and will be soon giving it another try. My normal test FC is a KK Minso Kim board that has no bells and whistles so I always have a benchmark to test and evaluate the aerodynamics. I then fit a MK board with the full kit. I am desperate to get away from MK and hopefully your code will be the answer. The thing that I thought might interest you is the fact that my MK boards are modified to take 67 deg/sec Gyros as I need to cage the models movements to stay within the 20 deg/sec that the camera mount uses. It is of course a bit risky if the mk gyros saturate as that would lead to a crash but I keep the stick inputs to a very low limit. The fast response and low noise seems to be the key to great stabilisation, plus the fact that the arms are 1 meter across with highly responsive motor/prop combination. The thought occurred that maybe we could develop a super stable version of AMP just for Aerial Video. The 500 deg /sec gyro does have amplified signal at 110 deg/sec but I expect that it will amplify the noise as well.
