How to import a 3D model into ros and define the joints , servo motors and gripper mechanism for simulations?
I am newbie to ROS and slowly learning urdf and moveit etc. I have designed my own manipulator in Solidworks and want to import it into ROS simulations. My question is how can I define where are the joints of my robot, where are the servo motors, basically HOW do I tell ROS that which is the part supposed to rotate around and which is to be a gripper.
