Description

Bionical regular hexagon Hexapod Robot
Technical field
The present invention relates to walking robot technical field, particularly relate to a kind of bionical regular hexagon six Biped robot.
Background technology
The conception of pedipulator is mainly based upon the rough topography variation of nature, bionical walking Robot is the forms of motion imitating animal, uses lower limb formula structure to complete various locomotive function Robot.Have been obtained for widely should with caterpillar type robot although wheeled in mobile robot With, but the requirement of walking robot road pavement is the lowest, the foot of robot had a large amount of from The motion that can be made robot by degree is more flexible, rough landform is adapted to ability higher; The foothold of walking legged type robot is discrete, with the contact area on ground is the least, and Ke Yi The optimum strong point is selected on accessible ground, even if in the case of surface is the most irregular, By the strict strong point selecting foot, it is also possible to walking is freely;Can apply to danger zone Detection, or the place that the mankind can not arrive, can also apply to Aero-Space, unknown celestial body Exploration environment.
At present, common walking robot has the application of two-legged type, all fours type more, and therein two Foot formula is less relative to six foot formula leg numbers with all fours type, and leg joint freedom degrees is less, transports to Underaction, dynamic stability is poor.The irregular Hexapod Robot body structure unshapeliness of part, Cause walking instability during advancing, be susceptible to rollover.And most of existing row Robot walking walking step state is fixing, the pass of body when so walking on rugged and rough steady road surface Joint will be severely affected power, it is possible to damages joint and drives element.
Owing to lower limb structure designs, the load capacity of major part walking robot is poor.
The control system of major part four feet walking robot is nonlinear multi input and multi output Time-dependent system, has time variation and interval dynamic.The walking movement of quadruped robot at present Great majority are geometric position based on gait trajectory planning, the planning of joint position control and control Strategy.And robot is carried out the planning of simple geometric position and controls, then can due to inertia, The factors such as strength of one's legs is unbalance and cause robot unstability.
And the existing legged robot of major part uses centerized fusion, i.e. robot All control to be completed by a microcomputer, may process not in complex road surface walking process In time.By the state machine that is made up of logic circuit of joint control, the therefore row of robot For being restricted, fixing forms of motion can only be presented.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of bionical regular hexagon Hexapod Robot, This robot includes the closed loop control system of regular hexagon fuselage, walking mechanism and control walking mechanism System, walking mechanism is regular hexagon frame, including three to machinery foot, wherein, every machinery foot Including composite rotating arm, galianconism, long-armed and for driving machinery foot to rotate in the horizontal direction Horizontal adjustment assembly, composite rotating arm is arranged on regular hexagon fuselage by horizontal adjustment assembly, One end of galianconism is flexibly connected with composite rotating arm by the first vertical adjusting part, galianconism another One end is flexibly connected with long-armed one end by the second vertical adjusting part, same on composite rotating arm Time steering wheel one and steering wheel two, long-armed upper installation steering wheel three are installed, the lower plate of composite rotating arm fills Having miniature bearing, composite rotating arm is by under miniature bearing and regular hexagon fuselage Base plate connects.
Wherein, closed-loop control system include pc machine, MCS 51 single-chip microcomputer, steering engine controller, Steering wheel one, steering wheel two, steering wheel three, micro radio transmission camera and pressure transducer, pc Machine connects MCS 51 single-chip microcomputer being loaded on regular hexagon fuselage, and MCS 51 single-chip microcomputer is even Connecing steering engine controller, steering engine controller controls steering wheel one, steering wheel two and steering wheel three, pressure sensing Device connects MCS 51 single-chip microcomputer, and photographic head connects MCS 51 single-chip microcomputer.Micro radio Transmission camera is arranged on regular hexagon fuselage, and described pressure transducer is arranged on long-armed.
Steering wheel one and steering wheel two are installed, by upper and lower two thin plates clamping steering wheel one on composite rotating arm With steering wheel two, steering wheel one is vertically placed, and is connected with regular hexagon fuselage by horizontal adjustment assembly; Steering wheel two horizontal positioned, is connected with galianconism by the first vertical adjusting part.
This robot leg has multiple degree of freedom, makes the motility of motion be greatly enhanced.It can Body levels is kept, it is also possible to adjusted by the extension degree of regulation lower limb with the length by regulation lower limb Gravity centre position, is therefore difficult to translate into, and stability is higher.
This robot has six miniature bearings, is contained in the connecting portion of leg and fuselage, Fixed plate so can be used to make leg fixedly secure between fuselage upper and lower bottom plate, considerably increase The load capacity of robot, expands the range of robot, compensate for major part robot The shortcoming of load capacity difference.
This bionical regular hexagon Hexapod Robot uses dispersion (level) formula and controls, and i.e. uses The control of robot shared by multiple stage microcomputer, as when using upper and lower two-level microcomputer jointly to complete machine During the control of device people, main frame is usually used in being responsible for the management of system, communication, kinesiology and kinetics Calculate, and send command information to subordinate's microcomputer;As subordinate from machine, carry out interpolation operation and SERVO CONTROL processes, it is achieved given motion, and to main frame feedback information.
The buffer unit of leg mechanism is requisite, and its leg joint is similar to animal leg joint, its Move through steering wheel to control.Its foot bottom, equipped with pressure transducer, can detect and ground automatically The state of face contact.The control that pressure transducer and attitude control system are made according to heat transfer agent Decision-making, it is achieved at the self adaptation static walking on out-of-flatness ground.
This robot is capable of the self adaptation dynamic walking on irregular ground, it is shown that biological sharp Encourage the advantage controlling that there is adaptive ability on unknown irregular ground.Its another feature is profit Navigate with micro radio video camera, can distinguish and dodge the obstacle that front exists, it is possible to Closing claustra realizes collisionless quickly walk.
This robot mobility and respond are the strongest, and balanced capacity is splendid, and has stronger Load capacity.
Having the beneficial effect that of the technique scheme of the present invention:
The requirement of this robot road pavement is the lowest, and a large amount of degree of freedom that the foot of robot is had make The motion of robot is more flexible, rough landform is adapted to ability higher;Walking leg formula The foothold of robot is discrete, with the contact area on ground is the least, and can be accessible The optimum strong point is selected, even if in the case of surface is the most irregular, by strictly on ground Select the strong point of foot, it is also possible to walking is freely;In load, stability, motility and over the ground The performance of the aspects such as the adaptability in face has obtained large increase, autonomy-oriented and intelligent ability and has obtained Highlight.Can apply to the detection of danger zone, or the place that the mankind can not arrive, also Can apply to Aero-Space, unknown celestial body exploration environment.Well solve existing wheeled and carry out Belt robot can not arrive the restriction of complicated ground, and the walking of other existing legged type robots Unstable defect.
