A long reach manipulator is required to investigate infrastructures and disaster sight. This paper proposes a new super long reach articulated manipulator whose gravitational forces are cancelled by multiple thrusters. The proposed manipulator has possibility to permit us to construct 20-30 meters long. To prove basic principle of weight compensation by thrusters, we developed 3 units prototype whose length was 3.0 meters. We successfully demonstrated 3-dimensional movement using thrusters and joint actuators.
