Embodiment
According to one embodiment, the concrete polished system of disclosure automation terrace robot contains a driving and promoted System, a navigation system and a user interface.In certain embodiments, operation logic is multiple soft with a computing device The form of part module provides.In certain embodiments, further comprise that the polishing area map and path planning side can be stored The storage device of case.Among some embodiments, further include an electric power management system 10, supply voltage is dropped It is low to use voltage to subsystem component (such as sensor, processor and encoder).Drive propulsion system, navigation system and use Family interface can be reequiped on existing concrete polished machine, or the two is selected first, these systems can also produce turns into A set of unified automatic coagulation soil polishing system.
Driving propulsion system has comprised at least a driver and one is connected to each driving wheel of concrete polished machine Encoder.In a configuration, driver includes a motor and controller unit.It is it will be understood by those skilled in the art that electric Machine is dimensioned so as to provide appropriate moment of torsion to move machine.
Concrete polished machine contain a grinding head for polishing, framework, driving wheel and other may be found that in handy concrete Part on polishing machine.Driver causes the rotation of driving wheel, but encoder accurately senses the rotation of driving wheel.It is logical The data for crossing encoder acquisition are mainly used in navigation system.If the concrete polished system combination of automation is to existing machine Device, the emergency braking system energy Constraints driven device of concrete polished machine.
In a configuration, concrete polished machine is moved with the linear velocity scope of 10-20 feet/min (0.05-0.1m/s) It is dynamic, it can be mentioned in the same breath with manual drive formula machine.The control of concrete polished machine linear velocity is by low speed on a drive What electric machine controller was completed.For the concrete polished machine of a differential gearing such as automatic coagulation soil polishing system, linear velocity It is coupling with steering angle.In other words, complete to revolve by one driving wheel of speed manipulation more faster than other driving wheels Turn.Speed command is combined by a single rotational speed command, is sent with a relatively fast speed (10-50Hz) To each driving engine.It is to reach desired drive characteristic using low speed drives manipulation device.
In a configuration, the barrier of automatic coagulation soil polishing system front and back monitors beam to concrete The whole audience motion of polishing machine provides the signal of a progress/stopping.In other words, obstacle avoidance sensor is known on its road by system Whether concrete polished machine encounters barrier in footpath.Obstacle avoidance sensor includes the ON/OFF touch sensor of binary.As long as touch Bump sensor is not triggered in the direction of traveling, and concrete polished machine can just move.According to use environment, if detected Barrier may need manual operation to restart the movement of concrete polished machine.
Navigation system provides the position for accurately determining automatic coagulation soil polishing machine.Using this set navigation system, from The concrete polished system of dynamicization can in working region from anywhere in calculate concrete polished machine absolute position and before Enter direction, relative to defined starting point.In no wall or foundation construction facility with the region of assisting navigation, can provide Artificial mark, such as laser reflector, it can help to navigate.Automatic coagulation soil polishing system at least relies on to a certain extent Navigation system could plan one imitate human manipulation (such as linear stretch beginning or terminate anticlockwise, right rotation, shake Movement machine is allowed to operate etc.) polishing coverage pattern.
In one embodiment, navigation system includes 360 ° of omnidirectional video cameras, can identify the artificial of fixation Road sign (such as coloured surface or lamp).Despite the system based on 360 ° of omnidirectional video cameras, calibration procedure should Implement in each new working region.Calibration contains short-distance movement polishing tool and artificial road is placed in working region Mark.Because the defects of with video camera basic system is relevant, laser range finder is may be used in an alternative embodiment.
In an alternative embodiment, laser range finder provides distance and bearing data without any complicated Processing, this puts different from the system based on camera.Because most of polishing operations are all carried out indoors, existing wall and angle Falling can be used to navigate by laser range finder as natural landmark.To the size in a typical retail shop, laser range finder can A scope with 360 ° of covering radius 30m can be needed.
In another alternative embodiment, long-range single-point laser rangefinder is arranged on continuous moving platform, Huo Zhean On the precise rotating platform with high-precision encoder.Compared with the laser range finder of 360 ° of coverages of band, single-point control Laser range finder is a more inexpensive part, but there is provided similar function.For example, a specific Laser Measuring The maximum magnitude of distance meter is 30m (can reach 150m on high reflectance surface) and 3mm resolution ratio.This system most represents The description of property is as shown in figure 9, including laser range finder and dial plate.In the embodiment of any description, laser range finder is most Good to be arranged on the column of concrete polished machine, so it can have one higher than people head and other ground in construction environment The clearly metope visual angle of face barrier.
Navigation system further includes an alignment system, and the data source that alignment system uses encodes in driving wheel Device (relative) and laser range finder (absolute) in working region from anywhere in the position of polishing tool that measures, advance Direction and speed.By measuring the rotation of driving wheel and knowing the diameter of driving wheel, it can calculate what each driving wheel was advanced Distance.From this information, the change in location or direction of advance of either concrete polished machine can be found when changing. In certain situation, it is inadequate to rely solely on driving steering wheel encoder and go to calculation position and direction of advance, because what it was provided An only increment measurement from start position.For example, it is wrong if driving wheel skids or concrete polished machine slides Value is introduced into measurement data by mistake.Therefore, laser range finder in working region by measuring the absolute of concrete polished machine Position and direction of advance carry out precise positioning.
The further use of laser range finder is one polishing area map of structure.In order to generating a polishing area Figure, laser range finder scanning work region is gone to form the 2D schematic diagrames of an existing wall and corner in working region.When mixed Polishing area map when native polishing machine is placed on its startup position is coagulated to start to generate.In other embodiments, polishing area Map can start previous existence into allow operating personnel to be examined or to be changed in polishing.Large-scale or less Typical construction environment, artificial target can be placed at the scene to identify the border of working region.Plate angle mark is most preferable Mark.Because they both provide X and Y dimensional informations.In this example, algorithm is looked in corner to be thrown relative to concrete The start position of ray machine, for finding (x, the y) coordinate at each angle.Because the start position of concrete polished machine is in working region It is inside that traveling is moving.For example, because the movement of concrete polished machine, laser range finder can continuously measure wall The position at angle is relative to its current position.One homogeneity conversion conversion local angle coordinate returns to global angle coordinate will It is found on initial polishing area map.
In certain embodiments, logical operation module is used for planning a polishing covering road in the form of a software module Footpath pattern.Logical operation module can be described as navigation system a part or it could also say that an independent subsystem. Logical operation module can further control and coordinate the various subsystems in polishing different phase, including control polishing mill The operating of head and speed.In more detail, operation logic module also can state of a control indicator lamp, signal lamp and concrete polished machine On other output.
Path tracing module is using the information for carrying out self aligning system, to export appropriate motor order, so as to along The path of planning accurately guides machine.One path tracing algorithm is also included, to be received from path planning system Path description.In a configuration, path description includes a series of straight lines and the point of rotation and formed, in opening for every linear path segment Begin that with the end of, concrete polished machine is rotated.For the point of rotation, concrete polished machine will simply instruct it to turn what is required Dynamic speed backspin goes to suitable direction, until it has reached desired angle.For linear path segment, there are several many institute's weeks The technology known, for calculating the appropriate speed command of each motor, to make machine be consistent with path.There is item to be claimed Technology for " pure tracing type " allows concrete polished machine to follow one in front of machine and is positioned in the void of path somewhere " target point " 65 intended.The distance of target point 65 and concrete polished machine 51 determines the susceptibility of steering order.(in other words Need to take a long time to keep aliging with path away from concrete polished chance too far away, but distance is too near to cause movement to be shaken again Pendulum).Pure tracing type operation method continuously calculates a radian 66 between the current location of machine and target point 65.Arc The radius of degree defines steering order.This technique chart is illustrated in Fig. 7 A.
Second technique chart is illustrated in Fig. 7 B, wherein also contains the concept of target point 65.However, substitution calculates One radian, this algorithm calculate the distance of driving wheel and target point.One shift control algorithm is driven by adjusting The speed of wheel keeps identical distance to proportional range difference.
When concrete polished machine has been placed on the starting position of polishing task, path planning system starts to start. Laser range finder measures to obtain a construction environment interior wall and the 2D " section " in corner first, obtains one and is made up of rectangular shape Region 50, as shown in Figure 4.The information in these regions is used by path planning system.Path planning system could be used that pass In whether the information that concrete polished machine 51 will be moved to the left or move right because this will determine that power line and concrete are thrown The position 52 of ray machine connection.Fig. 5 illustrates the example that concrete polished machine will move to its right.Performed in view of driving The power demand of device and grinding head for polishing, long-time polishing project need cable to be fixedly connected.Receive and believe from laser range finder After breath, path planning system is that polishing provides working region 53.Based on the initial position of concrete polished machine, this is probably The a subset of whole building area of base, as shown in Figure 5.
Once polishing region 53 is prescribed, path planning system using simple geometric reasoning method go build path and Whole coverage pattern.In first step, path planning system constructs a series of and concrete polished machine initial orientation Parallel " navigation channel 56,57 ", as shown in Figure 6A.If otch, the length in navigation channel may be different;Extend navigation channel 57 such as Fig. 6 A Shown in the right.Distance between navigation channel is by lap (one between the width (fixed value) of grinding head for polishing and desired navigation channel The individual value determined by operating personnel) determine.In this stage, the generation of series of concrete polishing machine motor performance guide.
As an example, in first step, concrete polished machine is along first in the path followed with concrete polished machine Individual navigation channel moves forward to the top of border 58 of working region, as shown in Figure 6B.Concrete polished one sideshake energy quilt of machine Automated procedures are incorporated into propulsion system easily to start to walk, but, it is necessary to operate completion by operating personnel for manual machines. Secondly, when concrete polished machine reaches the end in navigation channel, concrete polished machine is to anticlockwise (as shown in Figure 6 C), then to the right Rotation, goes to complete one to move back to starting point (as shown in Figure 6 D) second again after being then consistent with the first navigation channel. The anglec of rotation is the parameter set by operating personnel.
A rotation to the left and then to the right is first completed before second navigation channel is moved to (as Fig. 6 E describe).Start The second navigation channel (and the first navigation channel is adjoined) is polished, before being moved from the first navigation channel position, concrete polished machine is rotated into necessarily The second navigation channel 60 of angle direction.This movement is as fig 6 f illustrates.The angle 61 can be confirmed as the function of track spacing.Once turn Predetermined angular 61 is moved, concrete polished machine is diagonally moved to the second navigation channel 60.Because it is rotated its path It is parallel with the length in navigation channel.(as shown in Fig. 6 G-6F).And so on, until the polishing in all navigation channels of completion.
By user interface, operating personnel can be with the concrete polished system of auto-control.User interface can be attached to On concrete polished machine or it can pass through notebook computer, smart mobile phone or other mobile device wireless connections.One In individual configuration, user interface can enter on concrete polished machine also can be by remotely entering.User interface allows operator Member quickly and easily installs, and starts and stop automation mechanized operation.As a part for airborne setting, user interface contains one Individual button menu on concrete polished machine so as to allow operating personnel need not use computer port can just install and start from Dynamicization program.Such as digital potentiometric a knob or driver plate, it is allowed to which operating personnel go to debug the drive of concrete polished machine Dynamic speed.Abended for one or because of obstacle stopping event, it is necessary to which concrete polished machine is restarted in user's manual operation. Airborne user interface further contains the flashing beacon of an operation for showing it under computer.In a configuration In, user interface further contains a USB and ethernet port, for debugging to fix a breakdown purpose and software more Newly, data acquisition or other diagnostic functions.
Airborne user interface constitutes one between concrete polished machine and notebook computer or other mobile devices Wireless communication system, by a wireless connection of wireless router 21.Throwing is further comprises inside the function that airborne user interface provides Light coverage schematic diagram (namely concrete polished machine completes the place of polishing).The other information that airborne user interface provides In especially include operating time altogether, power on duration, the grinding head for polishing duration of runs, the path distance currently advanced, The ratio that current area coverage and current area coverage pattern are completed.
