Disclosed by the present invention is a system to control the operation of a capsule robot in a body. By an embodiment of the present invention, the system includes: a first capsule robot including a first housing which forms appearance, a first shaft which is movable in both directions along a first extension hole formed in one side of the first housing, a first permanent magnet which is in the outer end part of the first shaft, a first leg part which protrudes from the first housing to the outside and can be inserted into the first housing again, and a first control unit which controls the operation of the first shaft and the operation of the first leg part and a second capsule robot including a second housing which forms appearance, a second shaft which is movable in both directions along a second extension hole formed in one side of the second housing, a second permanent magnet which is in the outer end part of the second shaft, a second leg part which protrudes from the second housing to the outside and can be inserted into the second housing again, and a second control unit which controls the operation of the second shaft and the operation of the second leg part. The first capsule robot is fixated on an internal organ by extending the first leg part to the internal organ at a predetermined position in the internal organ. The second capsule robot is connected with the first capsule robot by allowing the first permanent magnet to be in contact with the second permanent magnet by human force.COPYRIGHT KIPO 2015본 명세서에서는 외형을 형성하는 제1하우징, 제1하우징의 일면에 형성된 제1연장홀을 따라 양방향으로 이동 가능한 제1샤프트, 상기 제1샤프트의 외측 단부에는 제1영구자석이 구비됨, 제1하우징으로부터 외부로 돌출하고 다시 상기 제1하우징내로 삽입 가능한 제1다리부 및 상기 제1샤프트, 제1다리부의 동작을 제어하는 제1제어부를 포함하는 제1캡슐로봇 및 외형을 형성하는 제2하우징, 상기 제2하우징의 일면에 형성된 제2연장홀을 따라 양방향으로 이동 가능한 제2샤프트, 상기 제2샤프트의 외측 단부에는 제2영구자석이 구비됨, 상기 제2하우징으로부터 외부로 돌출하고 다시 상기 제2하우징내로 삽입 가능한 제2다리부 및 상기 제2샤프트, 제2다리부의 동작을 제어하는 제2제어부를 포함하는 제2캡슐로봇을 포함하되, 상기 제1캡슐로봇은, 내장 내 소정의 위치에서 상기 제1다리부를 내장벽까지 돌출시킴으로써 상기 내장벽에 대하여 고정되고,
