Description
Technical field
The utility model belongs to underwater robot technical field, and in particular to a kind of wheel leg for amphibious ball shape robot
Formula composite driving mechanism.
Background technology
Along with human knowledge ocean, exploitation ocean, utilize the process of marine resources and protection marine resources, underwater
People as it is a kind of move under water, have vision and sensory perceptual system, by remote control or autonomous remote control mode, using machinery or other
Tool replaces or auxiliary people goes to complete the device of underwater operation task, the important role of performer in ocean development and utilization.
In recent years, underwater robot became the hot spot of foreign study.Massachusetts Institute Technology, Office of Naval Research, U.S. Navy
(ONR) it hovers nobody underwater autonomous boat with the third generation of company of Lan Qi robots of the U.S. (Bluefin Robotics) cooperative research and development
Row device (HAUV 3) is able to detect that the submarine mine of warship bottom, the shape of HAUV 3 are similar to a kind of underwater flying saucer.Tokyo
The URA development in laboratory of the university different AUV of multiple functions, such as " Twin Burger AUV ".Mitsubishi heavy industry exploitation at
" AUV-EX1 " of work(can carry out investigation and prospecting at most deep 3500 meters of deep-sea.The scientist of Kiel, Germany university develops novel
Deep water robot " ROV KIEL 6000 ", can test to the seabed of 6000 meters of depths, find mysterious deep water biology and " white
Gold " combustible ice.The country for autonomous robot research essentially around two centers, first, Chinese Academy of Sciences Shenyang is automated as
Center has developed R-01 types/CR-02 types (6000m) unmanned cableless underwater robot, has adapted to abyssal floor level terrain
Polymetallic nodule mining area working environment, detection content are only limited to acoustics, optics and hydrographic survey;Second is that big with Harbin Institute of Engineering
Centered on, military Intelligent Underwater Robots such as " intelligence water I ", " intelligence water II ", " intelligence water III " and " intelligence water IV " is developed.It is this kind of
Underwater robot is designed using torpedo-shaped streamlined structure, has the shortcomings that volume is big, turning radius is big, concealment is poor, can not
Complete the task in narrow regions.It moves the propeller used, easy tos produce noise, is not suitable for hidden and bioaffinity.
Compared with the underwater robot of torpedo-shaped, ball shape robot has more advantages, and symmetry is good, and control is relatively simple.
The country includes mainly Harbin Engineering University, Beijing University of Post & Telecommunication etc. to the research unit of underwater spherical robot.It 2007, breathes out
A spherical underwater vehicle that your the bionical Micro-Robot laboratory of shore engineering university is developed, sphere diameter 0.22m, air
Middle quality is 5.6kg, using two water spray motors as driving device, and water inlet and two water outlets there are two setting.The ball
Motion control of the shape underwater hiding-machine using the control method of attitude transducer signal feedback adjustment to itself, but due to its dynamical system
System design relative poor, kinematic dexterity is limited, and mobility is poor.The Sun Hanxu of 2010 Beijing University of Post & Telecommunications is taught and Lan Xiaojuan
Doctor et al. has also carried out relevant research to spherical underwater robot.Doctor Lan Xiaojuan et al. has delivered some correlative theses Jie
Structural configuration, operation principle and the performance parameter of the spherical underwater robot BYSQ-2 for the built-in attitude regulation mechanism that continued, ball
The a diameter of 0.54m of body, quality is about 80kg in air.The spherical underwater robot is by its internal double drive steering mechanism
The sub-aqua sport of six-freedom degree is realized in cooperation with screw propeller.But the build of the design is larger, in shallow water, natural pond
Limited viability under the environment such as pool, beach.
Traditional underwater robot is only suitable for environment under water, smaller to the application value of the amphibious environment of border on the sea, so right
It is significant in the research of amphibious robot.Company of IS robots of the U.S. has developed underwater autonomous robot ALUV, has
Six legs, there are two degree of freedom for every leg, have amphibious motor function, but it can only crawl movement, be only suitable for the bottom
Movement, and move distance is closer.McGill University in 2005 has developed a kind of amphibious robot Whegs of imitative cockroach, pusher
Structure uses the design of three spoke wheel paddle leg formulas, and approximate wheel can realize high-performance and steady propulsion.On this basis,
Georgiades C et al. have developed amphibious Hexapod Robot AQUA, and AQUA is promoted when land is moved using arcuate leg, profit
With the good feature of arcuate leg mobility height and versatility, the propelled at high velocity of a variety of terrestrial environments may be implemented;Under water, it utilizes
The flapping locomotion of six paddles, AQUA can realize the movements such as cruise, lifting, surging, steering, rolling.Since AQUA is on land mountain
The different propulsive mechanisms used under water require manual replacement driving mechanism when being converted.Tokyo winter evening university
The amphibious snake robot of the ACM-R5 of development, the snake robot are made of multiple joints, and there are two degree of freedom for each joint tool, can realize
Pitching and yawing rotation.When land moves, ACM-R5 is promoted by the wriggling movement of body, can also realize tumbling motion;
When moving under water, for ACM-R5 using the undulatory propulsion for imitating common eel formula, movement is slower.
Therefore, existing amphibious robot and amphibious ball shape robot have the following problems:
1 current amphibious robot generally uses bionic principle design, such as bionic cockroach and snake, bionic cockroach
Robot uses different driving structures with land under water, when switching under water with Land Movement, requires manual replacement drive
Dynamic structure.Bionical snake robot is designed using articulated type, and land and sub-aqua sport is slower, is only capable of reaching 0.4m/s.
The amphibious ball shape robot designed before 2, light weight is smaller for the pressure of leg, only with four pedipulators
It can realize and creep, but the ability for carrying sensor is smaller.In order to improve the intelligence of robot, so needing robot
With more sensing means, to need to increase robot size.With the increase of robot weight, only it is difficult by four legs
Meet prolonged movement, and the increase due to carrying number of sensors, causes robot weight larger, robot leg servo
Steering engine load-bearing increases, and increases the loss of robot servo steering engine.Existing ball shape robot is moved ahead using gait, and driving structure is watched
The number for taking steering engine is more, and energy expenditure is more, and uses same motor pattern in different landform, can not achieve energy-efficient
Purpose.
