INPUT DEVICE AND SURGICAL ROBOT

Disclosed are an input device and a surgical robot. The input device includes a mounting base, a rotation support, a grip mechanism, a connection member, a magnetic element and at least one first detection component. The rotation support is rotatable around a first central axis relative to the mounting base. The grip mechanism is disposed on the rotation support, and is transitionable between an open position and a close position. The connection member is connected with the grip mechanism, and is movable in a direction substantially parallel to the first central axis with opening and closing of the grip mechanism. The magnetic element is disposed on the rotation support or the connection member. The at least one first detection component is disposed on the mounting base, and is configured to detect a magnetic field direction of the magnetic element.
