A robot according to the present invention includes: a multi-tool module including a guide tube and a plurality of tools operated in conjunction with the guide tube and branched from the guide tube, the multi-tool module having a marginal degree of freedom and a control unit for generating a control signal on a motion in an articulate space on the multi-tool module based on motion instruction information on distal ends of the plurality of tools in a work space, and utilizing the marginal degree of freedom to generate a control signal. The present invention can expand a workspace of a tool and perform an operation which cannot be performed in a general tool control method, minimize necessary strengths for articulates of tools, minimize a possibility of a collision between a tool and a peripheral obstacle, minimize a necessary degree of freedom of the tool, and perform a complex task which could not be performed conventionally.COPYRIGHT KIPO 2014
