Abstract:
1. A mobile device equipped with an energy accumulation component, a plurality of translational mechanisms for translational movement of the mobile device which actuate by consuming energy accumulated in the energy accumulation component, a first temperature measurement component configured to measure or estimate temperature of each translational mechanism, and a control device configured to control operation of each translational mechanism, further comprising an energy remaining amount measurement component configured to measure or estimate an energy remaining amount of the energy accumulation component, wherein the control device is configured to control operating mode of each translational mechanism, in accordance with a temperature allowance of each translational mechanism which is a difference between a temperature of each translational mechanism measured or estimated by the first temperature measurement component in the state being smaller than a first temperature threshold value and the first temperature threshold value, or a sum of the difference and a proportional values of a temporal change rate of the difference, so that a heat generation amount of one translational mechanism having large temperature allowance compared to other translational mechanisms becomes larger compared to the heat generation amounts of other translational mechanisms, wherein the control device is further configured to control the operating mode of each translational mechanism so that a difference between a ratio of the heat generation amount of the one translational mechanism with respect to a total heat generation amount of a plurality of the translational mechanisms and a ratio of the heat generation amounts of the other translational mechanisms with respect to the total heat generation amount of a plurality of the translational mechanisms becomes larger, as a difference between the temperature allowance of the one translational mechanism and the temperature allowance of the other translational mechanisms becomes larger, and wherein the control device is further configured to control the operating mode of each of a plurality of the translational mechanisms, respectively, so that the difference between the ratio of the heat generation amount of the one translational mechanism with respect to the total heat generation amount of a plurality of the translational mechanisms and the ratio of the heat generation amounts of the other translational mechanisms with respect to the total heat generation amount of a plurality of the translational mechanisms becomes smaller, as the energy remaining amount measured or estimated by the energy remaining amount measurement component becomes larger.
