Renewable energy generation device and control method therefor

A method of generating renewable energy, the method comprising:

• calculating a position and an attitude of a renewable energy generator, shaped as a self-righting roly-poly toy or capsule, the renewable energy generator configured to convert wave energy into electrical energy to produce electric power;
• determining whether or not a pendulum needs to operate internally of the renewable energy generator;
• upon determining that the pendulum needs to operate, converting a main motor and an auxiliary motor installed internally of the renewable energy generator to a driving mode;
• and
• adjusting a tilt of the renewable energy generator.

A renewable energy generator, comprising:

• a housing configured to float in a body of water;
• a main generator comprising:
• an inner housing,
• a pendulum rotation shaft mechanically coupled to the inner housing,
• a pendulum configured to swing around an axis of the pendulum rotation shaft to cause the pendulum rotation shaft to rotate,
• a main motor,
• a gear linked to the pendulum rotation shaft and configured to transmit rotation of the pendulum rotation shaft to the main motor to cause the main motor to generate electrical energy, and
• one or more frames fixed internally of the housing;
• a main rotating shaft configured to link the main generator to be rotatable with respect to the one or more frames;
• and
• a controller configured to control rotation of the main rotating shaft to cause the main generator to move, so as to adjust a tilt of the housing with respect to the water.
