Random errors from time to time

[hidoba]

I'm using offline trajectory computation through Python, using the version compiled from this repo from May 15, (commit eb749af10fe10554bea795182209242a9c57433a). Running on Nvidia Jetson Nano. Errors happen every once in a while.

Examples of output when errors happen:

ruckig.RuckigError:

I experience the similar issue

inp.min_position = [-inf, -128.9, -inf, -147.8, -inf, -120.3, -inf]
inp.max_position = [inf, 128.9, inf, 147.8, inf, 120.3, inf]

This almost always happens closer to the end of trajectory
