How to use curve x1 y1 z1 x2 y2 z2 speed command

[markwinap]

Hi has anyone been able to run curve command on Tello SDK 1.3 or 2.0. I always receive "out of range" response from the drone.


Thanks

According to the SDK, the radius must be between .5m and 10m,
-500 < x1 < 500
-500 < x2< 500
-500 < y1< 500
-500 < y2 < 500
-500 < z1 < 500
-500 < z2 < 500
Using the Tello EDU app, the curve function works well.

I tried to run (with the help of 'python tello_test.py ') the command from the example: curve 50 100 100 25 50 75 25 but got the error message "Radius is too large"

I tried to run the curve command and it skips over it completely it doesn"t give an error message?

Hi t99bh541g,

Any News? so you are using coordination of curve 100, 0 , 50, 200, 0 ,0 ?

Thanks

The command 'curve 25 25 0 50 50 0 20' gave error: "Three points are collinear!"

curve 25 -25 0 25 -75 0 20 was performed by my Tello EDU without an error!
The curve is calculated by the 3 points: current drone position and 2 given in the command. I draw a picture of this: on it the curve is drawn red.

Dear Mike,

Wonderful and Thanks you very much I will try!

curve 70 70 0 140 0 0 20 will make a Tello fly half a circle clockwise with the radius of 70 cm at the speed of 20. (See my picture in the post before.)

how do you find the radius

 

[hellotello]

Scratch program to compute the center and radius of a circle given two additional points.

How do you change the value inside x1 to yc??

Thanks

Thanks for the useful program!

Hi everyone, I too am struggling with the curve command. I'm using the below node package in Visual Studio Code: tello-drone
(Not using DroneBlocks.... at some point I may switch to that but would prefer to stick with this method for now. It's worked for everything except curve so far!)

I keep getting an "Error: Unexpected 'z1' in options" response when I try to send a curve command (example below):

await drone.send("curve", {x1: 30, y1: 60, z1: 20, x2: 80, y2: 60, z2: 50, speed: 10 });

Has anyone else encountered this? I have checked my coordinates and the radius is within range. Also tried some of the example coordinates that @Mike Shock and others have posted. But no luck, so I think it may be an issue in the order of my commands? or something else?

Any suggestions or ideas are very welcome. Thanks!

Right now, I'll try to use what i've seen in this video.

Use this to get coordinates:

Desmos | Graphing Calculator

www.desmos.com

I tried with
(x-100)^2 + y^2 = 100
And for curve comamnd:
my_drone.curve( 0, 20, 60, 0, 180, 60, 20)
my_drone.ccw(180)
my_drone.curve( 0, 180, -60, 0, 20, -60, 20)
my_drone.ccw(180)

I haven't used X coordinate to make a vertical circle, using x,y will make horizontal circle. using either x,z or y,z will make vertical circle/curve.

x coordinate I got from the Desmos | Graphing Calculator was used as z coordinate. In tello z coordinate is for elevation.

Thanks for posting that image @Mike Shock makes perfect sense
