The present invention relates to a zero turning radius vehicle having at least one steerable front wheel and a multistage steering input system separately capable of steering the at least one front wheel and selectively driving the drive wheels. A front wheel steering system comprises at least one oblongated sprocket meshingly connected to a steering shaft. An engagement cam system provides the ability to selectively, independently couple the steering wheel to pump arms driving a first and second drive wheel. A steering cam shaft comprises at least one steering cam that acts on at least one bearing. Once the engagement cam system rotates the at least one bearing into place to receive the at least one steering cam, rotation of the steering cam independently alters the speed of one drive wheel in relation to the other drive wheel in response to steering input provided by the operator.

The invention discloses an omnidirectional single-spheroid self-balanced face recognition and tracking robot. The omnidirectional single-spheroid self-balanced face recognition and tracking robot comprises an attitude sensor system, a data handling system, a two-freedom-degree camera system, a servo motor control system, a movement control system and a touch display module, wherein the attitude sensor system is connected with the data handling system to send detected movement state data to the data handling system; the data handling system and the two-freedom-degree camera system are mutually connected to acquire and analyze image data of current environment; the touch display module and the data handling system are mutually connected; the data handling system and the servo motor control system are mutually connected; and the servo motor control system and the movement control system are mutually connected to jointly control the movement state of the system. The omnidirectional single-spheroid self-balanced face recognition and tracking robot disclosed by the invention has the advantages that the in-situ free steering and omnidirectional movement can be performed in a narrow space, so that the omnidirectional single-spheroid self-balanced face recognition and tracking robot can be widely used in crowded places including a hospital, a bazaar and the like, and the movement defects of inflexible movement manner including large turning radius, long consumed time and the like, and the abuses that an interaction manner is single and short of attraction, existing in a conventional movement manner, are overcome.

A bicycle handlebar includes a main body pivotally connected to a bicycle. A first holding portion and a second holding portion corresponding to the first holding portion are disposed at left and right sides of the main body. The first holding portion and the second holding portion each bend towards a forward riding direction and extend to form a forward bending portion. The forward bending portions each extend towards a backward riding direction to form a backward bending portion. The backward bending portions each extend towards the backward riding direction to form a rear section. A distance between the two backward bending portions is greater than a distance between the two forward bending portions, so as to expand a turning radius of the bicycle handlebar.

The invention relates to the technical field of automobiles, in particular to a manufacturing method of a multi-link rear suspension, a multi-link rear suspension and a vehicle. The manufacturing method of a multi-link rear suspension comprises the following steps: according to the existing multi-link rear suspension, the braking simulation test of the multi-link rear suspension model is carried out, and the influence positions on the low-speed bending radius and the high-speed bending radius are found out in the multi-link rear suspension model, and the hard points are marked; the rigidity, stiffness or position of the parts marked with hard points are adjusted, and after the adjustment, the braking simulation test is carried out again to obtain the final optimized multi-link rear suspension model; the multi-link rear suspension is manufactured according to the optimized multi-link rear suspension model, and the multi-link rear suspension is manufactured through the manufacturing method of the multi-link rear suspension to solve the problems of poor turning follow-up performance, large turning radius and poor maneuverability when the vehicle is steered at low speed in the prior art; and vehicles are unstable when they turn the corner at high speed, thus being prone to the technical problems of rear tail flick phenomenon.

The invention provides an unmanned ship. The unmanned ship comprises a ship body and a main propeller, and the main propeller is arranged at the tail part of the ship body; and the unmanned ship further comprises lateral propellers, the lateral propellers are arranged at the head part of the ship body, and the lateral propellers are used for generating propelling force in an angle with the lengthdirection of the ship body. According to the unmanned ship, the main propeller at the tail part of the ship body is used for generating propelling force, so that the movement is realized; when the extremely small turning radius movement is needed to be realized, the lateral propellers are used for generating the lateral propelling force to be matched with the main propeller, so that the free adjustment of the posture in an extremely small range in a dynamic state can be realized; and therefore, the unmanned ship can be matched with an underwater robot more flexibly, and the cooperative work ofthe unmanned ship and the underwater robot is guaranteed.
