Perfect! Thank you for this.
Is there any way of running this model at a constant speed? I saw something in the thesis about a predefined speed. Is this implemented? /Oskar torsdag 13 juni 2024 kl. 17:01:55 UTC+2 skrev [email protected]: > Hello Oskar, > > If you do not need visualization and are happy with the vehicle operating > on a rigid terrain, you could check out the library of low-fidelity vehicle > models - https://github.com/uwsbel/low-fidelity-dynamic-models.
