Re: Swarm with LPS and Polynomial Trajectory

Hi Kristoffer, "I assume you are running from python using the Swarm class and the high level commander? You mention that you use polynomial trajectories so that should mean that you upload the trajectories and essentially just send the start command?" - Yes!!! There is a lot of communication going ...

Swarm with LPS and Polynomial Trajectory

Hi, I need an opinion ... I implemented a swarm with 2 CF 2.0, 8 LPS anchors (TDoA 3) and polynomial trajectory. When selecting aircraft order: uris = { URI1, URI2, } I notice that the performance of URI1 is always better than URI2. Independent of the aircraft, the trajectory, the Crazyradio. But sh...

Re: Autonomous flight using LPS instead Motion Capture System?

Hi Santiago, My situation is more or less like yours. But I have only 4 CF 2.0. Have you ever messed with them? Did you take a test? Recommends that the first thing you do is install the library: https://github.com/bitcraze/crazyflie-lib-python And also Cfclient: https://github.com/bitcraze/crazyfli...

Trajectory Generator

Hi! Using the package to generate trajectories and unload on the aircraft ... I did some tests. I understand that the trajectory is smoothed and the restrictions of the aircraft are considered. But even so, I found the duration of the journey so long. A relatively short route that took longer than I...

Swarm and UAV Trajectory

Hi! In CF 2.0, I'm used to swarm flying using high level functions. And recently, I tested on an aircraft the UAV trajectory package, where you unload a trajectory based on polynomials ... Now I would like to join these programs. Swarm and trajectory. But I'm having problems ... I created a file to ...

Re: How to print the position with the swarmSequence.py

Hi! Now, the acquisition is operating well! I created two different callbacks: position_callback1 e position_callback2 def start_position_printing(scf): if scf.cf.link_uri == 'radio://0/80/2M': log_conf = LogConfig(name='Position', period_in_ms=500) log_conf.add_variable('kalman.stateX', 'float') lo...

Re: How to print the position with the swarmSequence.py

The code you have written so far looks good to start a log block. If you call swarm.parallel(start_position_printing) in the with swarm block, you will start to log position for all the drones in the swarm. The scf.cf object contains the URI of the link, this would allow to identify each Crazyflie ...

Could not connect to bootloader

Good Morning! To upgrade the Crazyflie 2.0 firmware: Press the ON/OFF switch more than 1.5 second until the blue led blinks. Then release the button and the two blue leds should blink. I have four Crazyflies 2.0. In three, the procedure was successful, however, in one of them there was an error. Onl...
