Gazebo Crashes when i try to detach a Screw Joint using plugin. Any one has a solution regarding this?

[GouthamG14]

#include <gazebo/gazebo.hh>
#include <gazebo/physics/physics.hh>

namespace gazebo
{
class DetachJoint : public ModelPlugin
{
public: void Load(physics::ModelPtr _model, sdf::ElementPtr _sdf)
{
// Make sure the model pointer is valid
if (!_model)
{
gzerr << "Invalid model pointer.\n";
return;
}

  // Make sure the joint name is provided in the plugin's SDF
  if (!_sdf->HasElement("joint_name"))
  {
    gzerr << "Missing <joint_name> element.\n";
    return;
  }

  // Get the joint name from the SDF
  std::string jointName = _sdf->Get<std::string>("joint_name");

  // Get the joint by name
  this->joint = _model->GetJoint(jointName);
  if (!this->joint)
  {
    gzerr << "Joint with name '" << jointName << "' not found.\n";
    return;
  }

  // Detach the joint
  this->joint->Detach();    //  To detach a screw joint
}

private:
  physics::JointPtr joint;

};

GZ_REGISTER_MODEL_PLUGIN(DetachJoint)
}

hm...I haven't tried detaching a screw joint before. Perhaps you could also test with the HarnessPlugin?

You can try replacing prismatic on the following line with screw and see what happens:

but in order to debug a segmentation fault; we would need a backtrace from gdb to see which code was being executed when it failed
