Eigengrasps for a parallel gripper

[ShrutheeshIR]

Hi, this work is amazing!

I plan on using a parallel gripper (fetch) for picking up objects. I came across this package, which seems to work well. I have a couple of questions regarding the same

1. Is graspit an overkill for parallel gripper, to generate antipodal grasps?
2. Would the eigengrasps for a parallel gripper just be the same as just regular antipodal grasps?
3. I tried loading the fetch_gripper with the longbox as object as an example. Although multiple grasps seem to be tried, it looks like it returns only ~20 grasps (using moveit_commander), just wondering which ones are actually selected.

Thanks
