A robotic system includes an end-effector configured for grasping an object, the end-effector including a suction cup assembly configured to engage the object, and a contact limit sensor configured to detect a pressure associated with the engagement between the suction cup assembly and the object, wherein the contact limit sensor transmits contact information when the contact limit sensor detects the pressure exceeding a contact threshold, a sensor unit monitoring contact information received from the contact limit sensor, and a controller, coupled to the sensor unit, configured to execute an operation for controlling the end-effector to limit movement of the end-effector toward the object based on the contact information received.
