The present disclosure provides a mouse. By positioning an elastic element at the distal end of the transmission section and applying a sustained upward biasing force, the force-receiving section maintains a tendency to move toward the trigger switch during both static and pressing states, achieving "zero-threshold" triggering. This significantly reduces pressing pressure and operational fatigue. The trigger switch is set at an acute angle to the base wall, ensuring the trigger arm’s movement direction remains perpendicular to the trigger key’s mating surface. The key mechanism employs a lightweight yet high-strength material, complemented by weight-reducing holes and reinforcing ribs on the transmission section, achieving an overall lightweight design while maintaining the rigidity and deformation resistance of critical components. A multi-layered limiting system—comprising bearing housings, baffles, guide protrusions, positioning shafts, and limit plates—effectively suppresses unintended movement and wobbling of the key mechanism in all directions, ensuring precise, stable, and durable clicking actions.

Suppresses unintended movement of movable parts. [Solution] The robot comprises a base, a movable part mounted on the base so as to be rotatable around a predetermined axis of rotation, an actuator that rotates the movable part around the axis of rotation, and a processing unit that controls the orientation of the movable part around the axis of rotation by controlling the operation of the actuator.
