JointController SetAngularVelocityTarget ? Hello it's me again, I am using a JointController to move my robots, however

Hello,

I am working on gazebo 7, and I use the official pioneer3-at source code. However, both my robots are falling trough the floor and I don't know why, here is the code, thank you in advance.

world.world

it was because of friction, thank you for your answer

but now my GetJointController()->SetVelocityTarget is not working anymore, I see the wheels are turning, but nothing

Hello it's me again,

I am using a JointController to move my robots, however I need to set an angularVelocity and I couldn't find this function in the documentation.

Does this exist ? If no, what other way to do do I have ? thank you in advance !

Official PIONEER3-AT model falling trough the floor Hello, I am working on gazebo 7, and I use the official pioneer3-at

Hello !

I am using GAZEBO 7 and ROS to make a simulation on pioneer3-AT for my internship.

I am facing a problem that is just blocking me for days, I have my plugin that at a specific moment is using the fonction SetLinearVel(), however, I can see that the model got an accéleration and then stop and just slide.

I wanted to know if there is a way to solve this issue ? I do need a constant velocity and I don't know how to do, here are my 2 functions :

    void definirVitesseLineaire(const double x, const double y){

        this->model->SetLinearVel(math::Vector3(x, y, 0));
    }

    void definirVitesseAngulaire(const double z){

        this->model->SetAngularVel(math::Vector3(0, 0, z));
    }

Even if my robot are going the same speed, they wont actually follow each other as they're supposed to do ( with my code ) because the ammount of time both of the functions above are being called is different from a robot to another. This is why I need a constant velocity.

Thank you in advance !

Hello,

I have a big problem of trigonometry, I want to convert the yaw of my robot from quaternion to radians using GetYaw() function, it's working pretty well, but I still have a problem.

I am using cos and sin functions but the robot orientation is now in radians but it's going from -pi to +pi, why wont it be like any normal trigonometric circle, from 0 to 2pi ?

Here there a way to change that ? Im pretty stuck at the moment and my brain is smelting, thank you in advance !
