2019-07-01 07:46:33 -0500 | marked best answer | Calculating inertial matrix for Gazebo I am having issues following the tutorial to calculate the inertial matrix for my gripper. This is the behaviour I see. I am able to successfully create a config package with PR2 gripper, so I am pretty sure it is because of the inertial matrix. In Meshlab, following are the values I get at no-scale: For a scale of 100, following are the values I get : How do I use these values? I didn't quite understand the scaling part of the tutorial. Also, ideally, shouldn't the simulation work when I consider the gripper to be almost weightless? A unity matrix or the above value as well gives the same behaviour as in the video. Edit 1: I have tested the macro mentioned by @Stefan Kohlbrecher. Also, I divided the inertia matrix given by Meshlab by volume which gives me : Still I observe the same behaviour. Does Gazebo need the inertia matrix wrt origin or wrt center of mass? Edit 2: @MarioSelvaggio 's solution seems to work perfectly fine. The arm is stable and I am also able to plan and execute trajectories. But the solution only works when in my final urdf file I translate the gripper : Observe that the sign of |

2019-03-01 16:32:03 -0500 | marked best answer | Ignore yaw of object for pick and place I am working on a pick and place application where I have to pick a dodecahedron with a vacuum gripper. The camera gives the object pose with respect to the bin it is in. I want to avoid rotating the 6th joint while grasping the object. As long as the object's top is flat, I can ignore the z-rotation. But this is not always the case, since there's a pile of objects. I have few ideas how to do this:
Any more ideas or a way to do one of the above are welcome. Thanks! |
