Regarding gripper control issues #50

When I control the gripper using the following code:

from panda_py import libfranka
gripper = libfranka.Gripper('172.16.0.2')
gripper.homing()
gripper.grasp(0.01, 0.1, 10)

the gripper closes and successfully detects contact with the object, but immediately after that moment it slightly opens, causing the object to slip and fall.

Why does this happen, and how can I prevent the gripper from opening after a successful grasp?
Is there something wrong with my setup or command usage?
