Can you correctly format the text please ? I reformatted your previous comment but won't do it each time...
Sorry for the bad format, I have reformatted the comment, thanks :D
How do you generate the path?
Basically you can extract the gridpoints location of the waypoints from the path, then look for these locations in the final trajectory.
Oh, I see, the gridpoints results could be found by jnt_traj.waypoints
, I just run my code, that's what I want. THANKS A LOT.
I generate the path by ta.SplineInterpolator
.
This is the jnt_traj.waypoints
time stamp results:

While the output = instance.problem_data
seems don't work, because output.gridpoints
is a default results.
Hello, in my project, I have 12 waypoints of a 6-dof robot to generate the trajectory.
In the code, the trajectory duration results is 36.084 sec, I want to find the time stamp of 12 input waypoints used to generate the trajectory.
gridpoints=np.linspace(0, 1, 10*(len(pts)-1)+1)
,len(pts)
is the length of my input waypoints, so the value of10*(len(pts)-1)+1)
is 10*(12-1)+1=111, so I print the gridpoints , but the results is not the time stamp of the gridpoints, this is the print results:output is : [0. 0.00909091 0.01818182 0.02727273 0.03636364 0.04545455 0.05454545 0.06363636 0.07272727 0.08181818 0.09090909 0.1 0.10909091 0.11818182 0.12727273 0.13636364 0.14545455 0.15454545 0.16363636 0.17272727 0.18181818 0.19090909 0.2 0.20909091 0.21818182 0.22727273 0.23636364 0.24545455 0.25454545 0.26363636 0.27272727 0.28181818 0.29090909 0.3 0.30909091 0.31818182 0.32727273 0.33636364 0.34545455 0.35454545 0.36363636 0.37272727 0.38181818 0.39090909 0.4 0.40909091 0.41818182 0.42727273 0.43636364 0.44545455 0.45454545 0.46363636 0.47272727 0.48181818 0.49090909 0.5 0.50909091 0.51818182 0.52727273 0.53636364 0.54545455 0.55454545 0.56363636 0.57272727 0.58181818 0.59090909 0.6 0.60909091 0.61818182 0.62727273 0.63636364 0.64545455 0.65454545 0.66363636 0.67272727 0.68181818 0.69090909 0.7 0.70909091 0.71818182 0.72727273 0.73636364 0.74545455 0.75454545 0.76363636 0.77272727 0.78181818 0.79090909 0.8 0.80909091 0.81818182 0.82727273 0.83636364 0.84545455 0.85454545 0.86363636 0.87272727 0.88181818 0.89090909 0.9 0.90909091 0.91818182 0.92727273 0.93636364 0.94545455 0.95454545 0.96363636 0.97272727 0.98181818 0.99090909 1. ]
