Disclosed is a power management apparatus and a multi-source energy harvesting system using the apparatus, which manage power supplied by individual harvesting sources without wasting the power, thus efficiently distributing the power to a battery. The power management apparatus includes a plurality of comparison units configured to compare voltages of storage devices respectively connected to output terminals of a plurality of harvesting power sources with a preset threshold voltage. A control unit is configured to control an operation of the power management apparatus. A plurality of switching units are installed between the storage devices and a battery and are configured to be turned on/off in response to switching control signals output from the control unit and to form power transmission paths between corresponding storage devices and the battery. The control unit generates and provides the switching control signals based on output signals of the comparison units.

The present invention relates to a manipulator having distributed mechanism for maximizing the performance of the manipulator. The manipulator is comprised of a first link; a second link; a joint for rotatably joining the first link and the second link each other; a connector having a first movable node at one end and a second movable node at the other end; a driver for providing power to linearly move the first movable node and the second movable node; and a guide for guiding the first movable node and the second movable node linearly. The first movable node is connected to the first link and is capable of linearly moving and rotating with respect to the first link. The second movable node is connected to the second link and is capable of linearly moving and rotating with respect to the second link.
