Description
Technical field
The present invention relates to machinery field more particularly to a kind of robots.
Background technique
Instantly, the research of legged type robot is started intimately, hexapod robot as one kind in legged type robot,
It can walk in unstructured or noncontinuity landform, while can be realized four-footed or even biped gait, compared with Conventional robotic
With very strong robustness and obstacle climbing ability.But the too high (Boston in the U.S. of current legged type robot or cost
Dynamics, Japanese Honda Company, domestic space tree science and technology, excellent essential legged type robot is all expensive, several hundred easily
Ten thousand price) cause common lab and research institution that can not do in-depth study to legged type robot, limit leg foot formula machine
Device man-based development.It is exactly class RHex robot (a kind of bionic 6-leg robot), this kind of rotation by leg reaches capable
Into the purpose with obstacle detouring, but this robot list leg can only lean on a motor output, and spring, obstacle climbing ability are not strong enough, movement
It is in the form of a single, it can not achieve and run in extreme complicated landform.In recent years, robot is in job that requires special skills, disaster relief or even army
Thing field has higher and higher application value, but existing hexapod robot all have cost excessively high while obstacle climbing ability at present
Undesirable disadvantage.Therefore, a kind of low cost is designed, has the characteristics that six foots of high output torque, high load capability, high stability
Robot is the emphasis of current research.
Existing patent retrieval is found, patent application publication number: 102267509 A of CN, denomination of invention: symmetrical bionic
Six sufficient running gears, using two structures, identical, centrosymmetric upper and lower layer tube-in-tube structure realizes gusseted for the invention.Its
Disadvantage are as follows: structure is complicated, and the starting time is long, and volume and weight is big, and the sensitivity that this also results in the system is not high, load capacity
Difference.
Existing patent retrieval is found, patent application publication number: CN 107651039A, a kind of denomination of invention: mechanical step
State synchronizes hexapod robot, which drives two groups of legs by two groups of transmission mechanisms.Its disadvantage are as follows: match firstly, being limited to processing
Precision is closed, this three legs synchronization realized using mechanical structure is more accurate unlike the system that each leg individually controls.Secondly, this
The addition of kind rotating mechanism is divided into two groups so that six legs are fixed, and every group of three legs must move together, can not achieve multiple
Miscellaneous gait.
Existing patent retrieval is found, patent application publication number: 20150041227 A1 of US, denomination of invention: SIX-
LEGGED WALKING ROBOT HAVING ROBOTIC ARMS FOR LEGS AND PLURALITY OF JOINTS, should
Invention controls the activity of leg by multiple steering engines, has imitated the design of mechanical arm.Its disadvantage are as follows: firstly, servo driving power is much
Not as good as motor, and simple joint only one motor driven;Secondly, this fisher's formula structure adds the system shape of topology
So that the torque that steering engine is born is very big, this also causes robot obstacle climbing ability very poor.
