Re: Model keeps swinging back and forth and is not fixed to the ground
Hi I have fixed it :wink: I added another ground plane on my own directly into the urdf file by adding another link (the ground) and a joint between this link and the base of my model like below. Pay attention that I used the Base link from my model as the parent and the ground as child, instead of ...

Re: Model keeps swinging back and forth and is not fixed to the ground
Hi, yeah sorry you are right, it is confusing terminology. And yes, I mean the base of the pendulum is shaking. So here is the original code: self.model = p.loadURDF(filename, flags=p.URDF_USE_SELF_COLLISION) So I tried this one, but it would not change anything so far. Any idea? self.model = p.load...

Model keeps swinging back and forth and is not fixed to the ground
Hi, I have the inverted pendulum modell below and it should be trained with reinforcement learning in pybullet. The problem now ist, that it doesn't stand still but it swings back and forth. Does anybody of you have an idea what could be the reason or how I could fix the model to the ground? <?xml v...

Re: URDF model falls through the ground
Hi, I used this script below. This script is working similar as this one: https://github.com/andreasBihlmaier/pysdf I'm not sure why your joints aren't working. How exactly did you generate the URDF? #!/bin/bash source catkin_ws/devel/setup.bash if [ ! -d "$2" ]; then mkdir $2 fi end_witho...

Re: URDF model falls through the ground
Wow, amazing, this is actually working!! Thankyou! Hi, All components within the same URDF model have collision with each other disabled by default. The easiest way to get ground collision is to load the ground plane in as a separate model. import pybullet_data p.setAdditionalSearchPath(pybullet_dat...

Re: URDF model falls through the ground
Hi, i have the following progress: I put a baseplate (ground) into the model and connected the ground with the base with a fixed joint like you can see below. Now the base part won't fall down, but the other parts still fall down. So it seems like the connections (joints) between the parts are not c...

URDF model falls through the ground
Dear all, I have the below URDF file. This is a description for a inverse pendelum robot which I want to train in a simulation with AI. When I load this file with pybullet for the training, it falls down through the ground and won't stop falling. Has anybody an idea what could be wrong with the URDF...
