Some use cases are running Webots containers through CI/CD on headless servers. WARNING: Cannot initialize the sound engine: Cannot initialize OpenAL default device 'OpenAL Soft'Īre there any ways of using hardware acceleration in the headless mode? You can try to re-activate some OpenGL features from the Webots preferences. Anisotropic texture filtering is not supported by the GPU.

Texture maximum filtering has been reduced due to GPU limitations. Main 3D view global ambient occlusion has been de-activated. Webots will run much faster after the installation of the correct driver.

#WEBOTS FITNESS FUNCTION INSTALL#

It is strongly recommended to install the latest graphics drivers provided by your GPU manufacturer.

#WEBOTS FITNESS FUNCTION SOFTWARE#

Webots has detected that your computer uses a slow 3D software rendering system. A recent NVIDIA or AMD graphics adapter is highly recommended to run Webots smoothly. Webots has detected that your GPU vendor is 'Mesa/X.org'. WARNING: System below the minimal requirements. WARNING: It is not recommended to run Webots as root. Xvfb-run webots -stdout -stderr -batch -mode=fast /usr/local/webots/projects/robots/clearpath/moose/worlds/moose_demo.wbt

With GUI + GPU in docker, I don't get warnings or it runs nearly as fast as a native installation. You can see that Webots warns that the system is below minimum. I believe that GPUs will speed up the simulations for cameras and video recordings, so in that case, I'd like to use GPUs in the headless. This is, to my knowledge, because xvfb will use software acceleration. This seems to launch Webots without GPUs (hardware acceleration). Xvfb-run webots -stdout -stderr -batch -mode=realtime /path/to/your/world/file In the headless mode, if we make gpus available to the docker container as follows docker run -gpus=all -it cyberbotics/webots:latest Pitch_input = k_pitch_p * CLAMP(pitch, -1.0, 1.I have tested Webots headless mode in docker as described here in Ubuntu 20.04. Roll_input = k_roll_p * CLAMP(roll, -1.0, 1.0) + roll_acceleration +i Actuate the motors taking into consideration all the computed inputs.

So can anyone tell me where I went wrong and if I want to create a delay between drone movements, what should I do? This is the code for movements that I have tried so far: // Actuate the motors taking into consideration all the computed inputs.ĭouble front_left_motor_input = k_vertical_thrust + vertical_input - roll_input - pitch_input +ĭouble front_right_motor_input = k_vertical_thrust + vertical_input + roll_input - pitch_input -ĭouble rear_left_motor_input = k_vertical_thrust + vertical_input - roll_input + pitch_input -ĭouble rear_right_motor_input = k_vertical_thrust + vertical_input + roll_input + pitch_input + I have tried to create that delay by using this code:` // Wait 5 seconds.īut it only works when left outside the control loop, when I use it inside the control loop`, it affects the drone's performance, the drone gets unbalanced and flies wildly. I want my drone to takeoff and after reaching the desired altitude, it will remain at that position for about 5 seconds before initiating some other moves automatically. I'm using Webots software to simulate a drone.
