The invention discloses a steering control method for a self-balancing two-wheeled vehicle. The two-wheeled vehicle comprises two separated split frames, a connecting shaft is arranged between the two split frames, and motors and gyroscopes capable of controlling the rotating speed of the motors are arranged in the split frames. The steering control method for the self-balancing two-wheeled vehicle comprises the following steps that firstly, the outer split frame needing to turn is treaded by the foot, and the inner split frame is kept horizontal. According to the split frame in the horizontal state, due to the fact that the gyroscope does not induct changes of the inclination angle, the motor does not rotate, the gyroscope at the bottom of an upper cover pedal inducts the changes of the inclination angle after inclination, signals are output to a circuit board to enable the motor to rotate, and therefore wheels are driven to rotate. Finally, one wheel does not rotate, the other wheel rotates, the two-wheeled vehicle turns and moves with the wheel which does not rotate as the center, the acceleration, speed reduction and turning functions can be achieved through foot treading, and the structure is simple.

According to the travelling mechanism, a closed force system is not required to be formed by an external spring force in the robot, and the worm drives the planetary gears to rotate, so that a transmission mechanism is integrated withan adjusting mechanism and the structure is simpler.

The invention discloses a quadrilateral rolling mechanism capable of steering. The quadrilateral rolling mechanism capable of steering comprises eight connection plates and connection structures thereof. Each connection plate is provided with two shaft holes; according to each connection plate, the perpendicular distances of axes between two shaft holes are equal; the eight connection plates form a quadrilateral, wherein the plates (1) and (2), the plates (3) and (4), the plates (5) and (6), and the plates (7) and (8) form four sides of the quadrilateral respectively; any adjacent connection plates are connected by a rotation pair; when the interior angles of the quadrilateral are 90 degrees, and the axes of the rotation pairs of the four corners of a square are parallel to each other, the mechanism has a square appearance; and the movement of the mechanism is controlled by motors (9), (10) and (15); and counter weights (11), (12), (13), (14) and (16) have the same weight as the motors to ensure that the structure of the mechanism is symmetrical. The motor (13) is controlled, so that the mechanism is deformed and rolls due to inertia; and the motors (9) and (10) are controlled, the mechanism is formed so as to swerve.

The invention relates to a swimming pool bottom hydro power pushed automatic cleaner, comprising an underwater cleaner and a control power supply which are connected by a buoyancy cable; wherein the underwater cleaner comprises a shell cover part, a shell body part, a filter, a double extension motor assembly, a hydro power driven jaw clutch pulley assembly, a water flow channel, a wheel and support, an isolated hood and a cable with a buoy. Along with the rotating direction of the motor, the hydro power driven jaw clutch pulley assembly is reliably meshed or separated under the action of hydro power; the pulley changes working condition, so as to realize jet water to be flowed out and further change travel direction of the cleaner; the shell touches wall to cause the cleaner to automatically adjust direction after touching the wall, so as to change travel route after touching the wall; and an arranged suction tube and a unidirectional drainage valve avoid eddy diffusion of travel of the cleaner on sewage at the bottom and reduce the weight of the cleaner when being taken out from water. In addition, two or multiple axial-flow pumps are arranged horizontally, so that the cleaner has turning function and ordered full cover washing is realized.

The invention relates to a multifunctional pipeline robot which comprises an advancing device, a sweeping device and a control circuit board. A driving device is arranged on the advancing device. The multifunctional pipeline robot further comprises a planetary wheel set A arranged on the advancing device and a planetary wheel set B arranged on the sweeping device, the advancing device is connected with the sweeping device through a spring, and a walking device pushes the sweeping device to advance in a pipeline. When the sweeping device encounters a curve, the spring can be net, and a steering function of the whole robot is achieved. Due to the fact that the walking device and the sweeping device are separately arranged, the length of the whole pipeline robot is quite decreased, and the phenomenon that the pipeline robot is clamped in the curve does not easily occur. The driving device adopts a worm wheel and worm structure, when the pipeline robot stops at a certain position in a vertically pipeline to perform sweeping or detection, a worm wheel does not drive a worm to rotate by utilizing the self-locking performance of the worm wheel and worm structure, and the phenomenon that driving wheel cannot reversely rotate and accordingly the pipeline robot slips down can be avoided.

The invention relates to a rollingly-marching robot with two wheel-like hexagonal mechanisms, comprising a connecting bar, the two independent wheel-like hexagonal mechanisms and connections, wherein each wheel-like hexagonal mechanism comprises three parallelograms consisting of nine connecting rods: two adjacent parallelogram share one side, the three parallelograms share one vertex and any adjacent sides are connected by using a revolute pair; two parallelograms are respectively formed by rods (1), (6), (7) and (9) and rods (2), (3), (7) and (8) and shapes of the parallelograms are respectively controlled by motors (14) and (15); and a servo parallelogram is formed by rods (4), (5), (8) and (9) and a counterweight (16) is of the same weight as the motors to ensure that the structure issymmetrical. The change of interior angles of the parallelograms is controlled to ensure that the mechanisms are deformed and rolled and the cornering of the robot is realized through the different rolling speed of the two parallel wheel-like hexagonal mechanisms.
