A six-axis motion mechanism combines three translation axes in the directions of the X-axis, the Y-axis, and the Z-axis and three rotation axes in the directions of the x-axis, the y-axis, and the z-axis to carry out a six-axis compound motion. The six-axis motion mechanism includes a movable support frame provided with a connecting mechanism. Drive mechanisms are provided in the directions of the X-axis, the Y-axis, and the Z-axis respectively for controlling the displacement, velocity and acceleration of three translation axes. Rotation mechanisms are provided in the directions of the x-axis, the y-axis, and the z-axis respectively for controlling the rotation angles (&#x3b8;, &#x3c6;, &#x3a8;), angular velocity, and angular acceleration of the three rotation axes. The six-axis motion mechanism further includes a motion body which can proceed its rotation and displacement at any angle to imitate a single motion of rolling, yawing and pitching and a compound motion.

A treading torque detection device includes a pre-set trading torque and a motor. The torque from the pre-set trading torque and the torque from the motor are respectively connected to a hollow tube mounted to an axle via a first one-way transmission device and a second one-way transmission device. The two respective powers are transmitted to a chainwheel by the hollow tube. A torque detection unit us connected to the hollow tube and located between the first and second one-way transmission devices. The power from the motor and the treading torques from the two ends of the axle do not affect to each other. When the torque detection unit detects a torque that is higher than the pre-set trading torque, the motor is activated to provide power, and the detected torque is reduced to the pre-set torque.

A water generator assembly includes a water generator having two forwarding wings on the front end thereof and the forwarding wings are applied by current and generate a resistance force and a lifting force. The resistance force and the lifting force are combined as a composition force which has a forwarding component force in the X-axis to offset the drag force cause by the current applying to the water generator. A component force in Y-axis is offset by the forwarding wings. A balance wing is connected to the water generator to prevent the water generator from spinning about the X-axis. The water generator has a lifting wing to generate a lifting force to lift the water generator. A buoyant floats and indexes the water generator. A tail wing and two side wings keep the water generator facing the current and prevent the water generator from spinning about the Y-axis.
