Starling 2 not following navigation path

greg_s

@ApoorvThapliyal, if you/your team needs anymore information or data, do let me know. Thank you.

Hey @greg_s
I just wanted to confirm, are you dragging the planned point to the height desired? By default, simply clicking on the map will generate a point at height 0.
Let me know, thanks

greg_s

Hello @ApoorvThapliyal,

Yes, I am dragging the point up and panning the camera around to ensure it is roughly the same height as the drone. The line drawn for the path is pretty straight and at the correctly level. The drone just ends up flying down below the point after I have move it.

Hello @ApoorvThapliyal,

Is there anything more your teams need to investigate/troubleshoot the issue? Thanks.

ApoorvThapliyal

Hey @greg_s
I was able to reproduce the issue where the drone does not fly correctly toward the setpoint. I think reviewing the extrinsics.conf file is a good next step, as there may be an incorrect transform defined there.

Hello @ApoorvThapliyal,

Is there anything that looks wrong or off about the configuration? Should I look at any other file in particular?

@greg_s
Hi there, your extrinsics are good: same as a factory Starling. Now, if you altered the voxl-camera-server.conf (e.g. enabled a flip of a camera stream when it wasn't) or physically changed a camera mount point then the extrinsics would need to be adjusted. Let assume that's not the case.

From your vvhub trajectory output, it appears your setpoints command the vehicle to move forward (X) and to the right (Y) > 1m while dropping altitude (Z) 0.8m --recall mapper runs in FRD (aka body) space where Z up is negative. Also you do pass through the take off origin (0,0,0). If that's not what you wanted, then we have a "requested trajectory" drawing problem in the portal tool or mapper's found invalid regions/obstacle and could not draw the "requested trajectory".

In the former case @ApoorvThapliyal mentions the un-intuitiveness of the portal tool that you already understand.

In the latter case, upon "request trajectory" submission, voxl-mapper will analyze the map to see if there are obstacles and alter the trajectory to fly around potential obstacles. You can alter in voxl-mapper.conf:

rrt_min_distance (try 0.125)
esdf_inner_sphere_radius (try 0.15)
if you seeing mapper create trajectories going around 'ghost' objects. This should allow RRT generated trajectories to get closer to objects.

In checking precision, you'll need to take the trajectory output (e.g. the setpoints in the *commanding: XYZ* messages) and compared it against VIO position to determine tracking error. You have 2 ways to get that data:

option 1 is record you vvhub traj output as above and record the output of voxl-inspect-vins -n then plot compare the tracking error.
option 2 is running voxl-vision-hub --debug_offboard --debug_odometry which you'll need to seperate the traj messages from the vio (T_body_wrt_local) messages, then you ca plot the tracking error.

The goal is we want the vio position to follow the commanded trajectory: (it's doing what is told to do). That will narrow down where your concerns are w.r.t what module has a problem.

Hopefully that gets you on the right track, just post any outputs you gather that continue to show tracking error.

Hello @Cliff-Wong,

I collected the output from voxl-vision-hub --debug_offboard and voxl-inspect-vins -n. I place a plan_to point that was about half a meter from the drone and slightly higher in altitude from the drone. I used the arrows to position the plan_to point and rotated camera to ensure the plan_to point it was placed correctly. I reduced the rrt_min_distance and esdf_inner_sphere_radius as suggested. The drone had more than a meter clearance on all sides. The room is empty with no obstacles.

I am not sure if the Portal is creating/sending the correct point shown on the map. Is there a way to send a point via the command line? I couldn't find anything specific for this.

@Cliff-Wong. For completeness below is the output of the start of voxl-vision-hub --debug_offboard. I trimmed the entire output above until the drone started to move from the plan_to command.

@greg_s said in Starling 2 not following navigation path:

One thing that looks suspect is the voxl-mapper pipe size 64k bytes is much smaller than expect (usually in MB, e.g. 32MB-64MB). Is this a preloaded 3D map?

Otherwise your VIO data looks good. It appears the drone does go to the 1st setpoint (1st leg of the trajectory) where that setpoint also looks as if it is landing. It's possible the landing detector was triggered and why everything stops.

I suggest the following:

power up, ssh into 2 terminals
terminal 1 -- run the voxl-mapper
terminal 2 -- run voxl-vision-hub --debug_offboard
take off in position mode, bring up the portal into mapper 3D view as normal, perform a 360 yaw to get a good map
Select "Plan a Point": draw your point and position it correctly
switch to offboard mode (which you have set correctly to 'trajectory')
Select GO!
Select "Follow Path"
(If no follow path is offered then the A* path creation failed)

Hopefully with that sequence, you'll see the drone move along the path. If it does not, then the voxl-mapper output in terminal 1 will tell us if a latency is the culprit.

As an example, here's how I expect the above to play out.. If you cannot repeat this then it maybe worth upgrading to SDK 1.6.3 (as the example was generated in).
