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.

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.
