Description
The present invention relates to a kind of mobile robot, relate in particular to a kind of movable spherical robot that utilizes the motion momentum to strengthen obstacle climbing ability, belong to electromechanical integration technology area.
In the prior art, designed multiple motion being applicable to complex-terrains such as mountain region or lunar environment,, joint-wheeled hybrid, joint track type etc. as leg formula, leg wheel.Yet the statics balance constrained designs is all deferred to by these mechanisms, and the input energy of system is mainly used in and overcomes static force, all intrinsic contradictions between the locomotivity of resolved vector and the landform adaptability fundamentally not.Along with the raising of movement velocity, compare with gravity when can not ignore when inertia force, system then enters dynamic state of run, and operation produces a very large impact the dynamical perturbation that is produced by landform at random to system, and the energy of input is mainly used in momentum control.Therefore, how to utilize the motion momentum to improve the major issue that locomitivity is current mobile robot's research.
Because of spheroid has good direction of motion controllability, there is not nonholonomic constraint, motion continuity is strong, and more existing in the world scholars launch the discussion to spherical travel mechanism.1998, American National Air and Space Executive Agent (NASA) jet propulsion laboratory (JPL) also once proposed a kind of robot probe's device that seems to be huge ball of design.This ball detector in light weight, the outside is hard, transparent, whippy shell, inside is filled with the air of suitable pressure, and in addition, it also has orthogonal rope, lie in respectively on the transparent outer cover of ball, make ball that light, soft, flat three kinds of forms be arranged, a control cabinet is made up of three motors, power supply (comprising solar cell) and control circuit, and control cabinet can move along three ropes by serving, to change the center of gravity of ball, make its direction motion to hope.The diameter of ball is very big, is enough to make it to overcome the very ground shape of hollow, because the function that do not move upward of this kind ball formula robot, so when it is not fragile when cliff or slope roll down.The Yangsheng Xu of robot research institute of Carnegie-Mellon University has developed that a kind of Gyrover is a sharp cincture with the stable single-wheel mobile robot Gyrover of gyroscope, and actuating mechanism is contained in the wheel, comprises three actuators.A high speed rotation motor, it drives a suspension flywheel and rotates at a high speed, so that Robotic Dynamic is stable; A canting motor, the angle of its control rotary flyweights, thus control turning to of Gyrover; A CD-ROM drive motor is controlled the acceleration that moves forward and backward by the inside wobble quality that changes Gyrover.Gyrover is a kind of novel single-wheel, gyro-stabilized robot.The behavior of Gyrover resembles stable rolling wheel based on the basic principle of gyroscopic procession.When the static and microinching of wheel, gyrostatic angular momentum guarantees the lateral stability of wheel.A kind of leaning device produces the inclination of wheel wobble shaft.Because gyroscope can be regarded the internal reference of attitude as, banking motion will cause that wheel tilts to the left or to the right, thereby cause that wheel is to the directional steering that tilts.The Torque Control that is produced by drive motors is suspended on the internal mechanism that resembles single pendulum on the wheel shaft, thereby produces the thrust of quickening or braking.
Japan scholar Atsushi Koshiyama and Kazuo Yamafuji just began taken turns the inside of forming by inverted pendulum and auxiliary rocker arm since 1985 be that the movable spherical robot of wheelbarrow structure is studied, purpose is to realize the attitude stabilization of robot, turn to control, carry out the climb and fall easy motion by rocking arm wheel and main body wheel.When if balance phenomenon takes place, this robot can keep stable state by the coordination of rocking arm and wheel.
Generation and practical application that the existing carrier of moving robot design studies of carrying out based on dynamic stability all fails to solve well effective exercise realize this critical problem.Gyrover puts undue emphasis on the pursuit dynamic stability, does not consider the self-sustaining of static stability, does not use gyro principle fully, causes energy loss very big, the control system complexity.In addition, environmental factor is not considered in its dynamic analysis.Although have motion diversity and the advantage of controlling simplification by the mobile robot that Japanese scholar developed, still lack enough operability and landform adaptability.The control of this robot system is a desirable Physical Experiment model only based on accurate kinetic model, is not suitable for being applied to mobile vehicle.Especially when practical application, lag behind because of life period between the response of system and the action of its internal soundness piece, be the function of outside landform lag time, be difficult to prediction, the controllable action speed when this has just limited it and is applied to complex-terrain can't surmount the quasistatic motion state.
The objective of the invention is to above-mentioned deficiency at prior art, provide a kind of novel ball carrier of moving robot from dynamic process stability angle design, make it to be applicable to complex-terrains such as mountain region or lunar environment, fundamentally solve the contradiction between landform adaptability and the locomotivity, can satisfy practical application request easily.
