Wearable apparatus for assisting muscular strength and a method for controlling the same

A wearable apparatus for assisting muscular strength, the wearable apparatus comprising:

• a support unit located on a rear surface of a wearer;
• an actuator located on the support unit so as to be fixed thereto;
• a sliding unit slidably connected to the actuator and being slidable with respect to the support unit due to driving of the actuator;
• a first rotating unit and a second rotating unit connected to the support unit to be located at both sides of the wearer such that one end of each of the first and second rotating units is coupled to the support unit so as to be rotatable forwards and backwards with respect to the support unit;
• and
• a power transmission unit provided with respective ends coupled to the first rotating unit and the second rotating unit via the sliding unit and configured to generate rotary force of the first rotating unit and the second rotating unit due to sliding of the sliding unit.
