Abstract: A surgical robot including at least one contact module, a control connection module, at least one first robotic arm, and at least one grip control device. A first transmission member of the control connection module drives the control module through a first transmission connecting member. A first shaft member of the first robotic arm is connected with the first transmission member while the grip control device is connected with the first robotic arm by a transmission interface. A force sensing member of the first robotic arm detects a first reaction force from the contact module so that the first robotic arm sends a feedback control signal to the grip control device to control a grip driving member to generate a force feedback for allowing a grip portion to move. Thereby, users can feel movement of the grip portion caused by the force feedback to avoid accidental iatrogenic injuries.

The discontinuous islanded ferromagnetic recording film includes a substrate and a ferromagnetic layer.
