Intelligent transportation robot of electric power storehouse of the present invention, with existing electric power storehouse and storehouse thereof, facility layout, electric power tool for basic object, with interrelated datas such as electric power storehouse work apparatus producers for design considerations, system realizes Intelligent transfer robot in electric power storehouse and independently moves to take article, as: insulating cord, felt pad, insulated target, insulation clothing, insulating glove, safety cap, insulating bar etc.
Specific embodiment:
1, as shown in Figure 1, whole Intelligent transportation robot of electric power storehouse System's composition comprises:
Robot car body and parametric controller, remote computer wireless control platform, article storage shelf and article object shelf are formed.Wherein robot car body is with can the Three Degree Of Freedom paw of automatic capturing and placing articles, and remote computer wireless control platform comprises department of computer science unifies item database management system and wireless sending module.And article storage shelf and article object shelf all have article acquisition sensor array to arrange, independently move to take type of goods more, as: insulating cord, felt pad, insulated target, insulation clothing, insulating glove, safety cap, insulating bar etc.Ground can also be arranged and be provided with the tracking line of robot car body for independent navigation.The function of robot will be set out according to the actual conditions in on-the-spot place, carries out planning and designing, carried by the electric power multiplexer apparatus of difformity, size, weight, material, disposing way by robot autonomous.Mainly comprise two processes: namely carrying grabbing and carrying are placed.
Carrying grabbing is the positive process being transported to article object shelf from article storage shelf, whole process is the product data base management system on remote computer wireless control platform, control command is sent by wireless module, robot controlling platform on robot car body nearby receives control instruction, at infrared sensor, sonac, alignment sensor, article acquisition sensor array, under the feedback information of the multiple sensors such as motor code-disc, the independent navigation of robot car body is realized by intelligent control algorithm, turn and realize the bar-code identification of article under cooperation by paw sensor and accurately capture, finally by robot car body by article carrying to the article object shelf of specifying.
Carrying is placed and is carried out the identification detection process same with carrying grabbing, is negative process article carrying being placed into carrying grabbing in process on the shelf location of specifying.Robot hand is very important part structures, realize three degree of freedom.Car body needs owing to turning to realize turning by differential rotating speed, and therefore robot car body adopts the four wheel mechanism motion mode to directive wheel after forward direction Dual Drive.And whole car body will realize the even running of climb and fall, in order to ensure that car body front-wheel and driving wheel are not stuck at the bottom of slope when going up a slope, do not cause side to be faced upward with driving wheel when pushing up on slope unsettled simultaneously, need to adopt quadric chain to carry out centre of gravity adjustment at the driving wheel place of vehicle body hanger, enable the driving wheel of robot car body not dieback at the bottom of slope, top, slope is not unsettled, always keeps and earth surface, thus provides the power of the reverse friction needed for driving.And the driving torque of expanded motor is wanted when going up a slope, descending will carry out self-actuating brake according to actual grade size, thus guarantee robot all can stable operation in carrying grabbing and carrying placement two processes.
The control method that positive and negative two processes are placed in carrying grabbing and carrying comprises navigation, multisensor identification, motor closed-loop control etc.The tracking navigation navigating through graticule on the ground of robot and hyperacoustic detection navigate mode combine, and so both ensure that the accuracy of robot crawl and placement two processes also ensure that the independence of robot.Robot autonomous navigation sensor and shelf acquisition sensor array junctions to be carried out altogether autonomous carrying grabbing and carrying placement, wherein the layout and putting of shelf acquisition sensor array also will combine with the digital bar code on paw acquisition sensor, article, only have and these sensors are organically combined, utilize appropriate control logic method, autonomous crawl accurately and the placement of robot could be realized.Whole robot realizes control command and Condition Monitoring Data transmission by wireless.Robot car body power supply is powered by chargeable battery pack.
In embodiments of the invention, in order to realize above said robot function, in design following technical requirement is proposed to robot:
Robot can receive the instruction that existing upper computer software moves to take article and accurately responds and carry;
By wireless transmission control instruction, robot is controlled and data transmission;
Robot can under the guide of navigation system autonomous;
Robot can the carrying article of autonomous classification upper computer software instruction indication; And article are transported to smoothly the storehouse destination of specifying;
Robot is by rechargeable battery powered, and continuous working period is no less than 6-8 hour;
Robot has autonomous climbing capacity and crosses over step ability, and ramp angle is not less than 15 degree;
Robot has voice broadcast ability and fault alarm ability;
Robot can even running, carries out single access to each article;
Robot has the paw Grasping skill adapting to various article difformity, size, weight;
Robot has handling preferably, and volume weight adapts to the space requirement of existing storehouse.
2, as shown in Fig. 2 a, Fig. 2 b, the design of storehouse part comprises:
The specifically pattern of putting of the interior layout of storehouse and shelf location and article work apparatus is the important component part of whole robot development, only have rational layout and laying for goods pattern, article are sorted out, correct accurately crawl that can realize robot hand identifies and carrying, the more convenient navigation of ability and robot obstacle-avoiding, sorted out by concrete work apparatus simultaneously and measure the specific design parameter foundation that just can provide mechanical paw.
Particular content comprises: storehouse layout, shelf and put, article instrument measure, navigation tracking planning, acquisition sensor arranged in arrays.
