The present invention is a method for refining native biomass to extremely fine and highly disrupted particles using high shear andor cavitation in combination with high temperature and high or low pH conditions which dissolve biomass to a high percentage. In addition, in a movable robot apparatus and its control method, a safety level status detecting means for detecting a safety level status and a control means for performing a control process so as to implement prescribed countermeasures depending on the position of the safety level status detected by the safety level status detecting means are provided. The mobile electronic device responds to the message with a response indicative that the data is to be archived. A first driver circuit is connected to the control terminal of the first transistor and is configured to control a current flow through the first transistor in a forward direction.
