Hello!
I am Huzaifa and am a PhD student at one of the labs that actively develops
Project Chrono. I am mostly involved at the moment with the Fluid-Structure
Interaction part of Chrono (Chrono::FSI). However I would be interested in
doing this as a side project and would love to help you in th
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. Herein
there are 3 models with varying fidelity, the 11 DoF model wh
Hello Mason,
Can you please also attach your CMakeCache.txt file? You will find it in
your build folder. Also please attach the CMakeOutput.log file which you
will find in build_folder/CMakeFiles

Hello Jay,
Unfortunately the Depth Camera is not yet packaged with Conda. This should
be out in a few weeks.
However, if you want to use the Depth Camera right now, you can but you
will need to build the pychrono packages from source

Just to add,
Fixing the Numpy include path will probably work, but if you don't want to
build gym-chrono yourself from source and want to get up and running
quickly, you could also set-up a docker container using instructions from
here - https://github.com/projectchrono/gym-chrono/tree/master/
Hi!
Did you build from source or used the conda package?

Hello Urara,
The code I provided for toe_in_r is what I suppose is the \delta from your
image. However note that the vehicles in PyChrono are 4 wheeled, so you
might need to make an approximation to get the \delta from the image (maybe
take the average).
That being said, from your plot, it is
Hello,
Have you added the path to external libraries in your cmake GUI?
For example, for vsg, see point 3 under "Building Instructions".

This is also the same for the parsers module

Hello Yaso,
It might not be the best to use a PyChrono vehicle as the vehicle model
inside a MPC controller. Why this is not the best of ideas is exactly for
reasons like this, it is difficult to linearize all the states of a
PyChrono vehicle model to get the Jacobian matrices A and B. A PyChr
Hello Jason,
We are currently using Project Chrono for RL but through PyChrono with
gymnasium. The latest iteration (unreleased) of this is here -
https://github.com/Huzaifg/gym-chronoV2
We would be very interested in using a native C++ RL library as this would
greatly improve our workflow :)
Hello,
Do you want to get the angle by which the tire-wheel steers? GetSteering
will only give you the normalized steering input (between -1 and 1) that
the driver applies onto the steering wheel at the current time step.
If you would like to get the tire-wheel steer angle, you could do somethi
Hello Alex,
The "Profile" struct information can be found here -
https://api.projectchrono.org/structchrono_1_1vehicle_1_1_ch_a_n_c_f_tire_1_1_profile.html.
It describes the entire contour with a cubic spline approximating the
points. See piece of code below from the source code

Hello!
Can you please try pressing the throttle for longer and seeing if the
vehicle still does not move? It is normal that there is a lag between the
application of the throttle and the movement of the vehicle. This can be
due to two reasons
