Abstract: A heat dissipating system of movable robot is provided. The heat dissipating system includes a movable robot and at least one wind resistance structure. The movable robot includes a housing, at least one airflow passage and plural first air holes. The housing defines an inner space, the airflow passage is disposed in the inner space, and the first air holes are disposed on the housing and are in communication with the airflow passage respectively. When the movable robot moves, an air current is generated accordingly. The air current partially flows into the airflow passage through the first air hole acted as an inlet, and the air current in the airflow passage is released from the first air hole acted as an outlet. The wind resistance structure is configured for guiding the air current into the first air hole acted as the inlet.
