The present disclosure relates to a map creation system and a method thereof, and more particularly, to a map creation system and a method thereof for a movable robot.


2. Description of the Related Art

In recent years, some nuclear power plants in Taiwan are planned to decommission.


However, it is very difficult in management, maintenance and repair for internal pipelines of nuclear energy components of the nuclear power plant because the pipelines are disposed densely and have various structures, and it is also unable to enter the pipelines for check, and the check operation must build construction frames and deconstruct adiabator first. For this reason, a robot having advantages of small-size, multiple degrees of freedom, light weight, simple operation, easy installation and repair, is expected to assist in decommissioning nuclear power plant. Besides the nuclear power plant, a petrochemical industry plant must be continuously operated for a long time and cannot be shut down for periodic maintenance and repair anytime, so the petrochemical industry plant also has risks of pipeline corrosion, pipeline breakage, pollution due to pipeline leakage, or fire explosion. If the robot can be applied to detect hazard and re-draw the pipeline map, the hazard risk of the nuclear power plant or the petrochemical industry plant can be greatly reduced.


In the world, Unite State is a country where most nuclear power plants are decommissioned, and there are about 30 nuclear power plants are decommissioned or being decommissioned. The internal pipelines in the nuclear power plant are disposed densely and have various structures, and it is unable to enter the pipeline for check, and check operation must build construction frames and deconstruct adiabator first, so it is very difficult in management, maintenance and repair. As a result, before the decommissioning operation of the nuclear power plant, the multifunctional robot can be applied to draw the pipeline map, detect dose, sample nuclide. Furthermore, there are various transportation pipelines, of which total length is 4.2 million kilometer of on ground or underground in the United States, and the pipeline information is collected and managed by U.S. department of transportation, pipeline and hazardous materials safety administration, so as to provide a communication platform between U.S. state government and industry, and provide transparent information for people.


Therefore, how to safely and efficiently decommissioning nuclear power plant is an important topic. During the process of decommissioning the nuclear power plant. A lot of pipeline robots are required to explore the pipelines, detect and sample radiation; however, most available robots are developed for manufacturing industry, and fewer robots are developed to operate in the pipeline with a small space and highly complicated environment. Each of the internal pipelines of the nuclear energy components in the nuclear power plant has small space and highly-complicated terrain environment. Under a condition that the staff members and large-sized machines are unable to enter the pipeline to explore internal environment, how to transmit critical messages associated with internal environment of the pipeline to outside staff member is very important. However, existing pipeline robot is unable to draw the route map accurately

Please refer to FIGS. 1 through 3, which show a first block diagram, a schematic view and a second block diagram of a map creation system for a movable robot, in accordance with the present disclosure. As shown in FIG. 1, the map creation system comprises the plurality of movable robot 10 and a display device 20. The movable robot 10 comprises a robot body 100, a driving unit 110, an image capture unit 120, a sampling unit 130 and a control unit 140, and a power supply unit 150. The driving unit 110, the image capture unit 120, the sampling unit 130, the control unit 140 and the power supply unit 150 are disposed on the robot body 100.


In a user end of controlling the movable robot 10, the display device 20 can be, for example, a personal computer or a cell phone. The user end can use a LabVIEW control program installed inside to transmit a control instruction to control the movable robot 10 the control unit 140 of the movable robot 10. For example, the control unit 140 can be a micro Arduino pro mini microcontroller development board, which is electrically connected to the driving unit 110, the image capture unit 120 of the movable robot 10, and the sampling unit 130. When receiving a control instruction from the display device 20, the control unit 140 can directly control the driving unit 110, the image capture unit 120, and the sampling unit 130 to operate, and indirectly control the operation of the robot body 100. The following describes the detail of the operation of the robot body 100.


The robot body 100 is mechanically connected to the driving unit 110, and the driving unit 110 can drive the robot body 100 to move in the space, for example, move in the internal pipeline of the nuclear energy component of the nuclear power plant, but the present disclosure not limited thereto. As shown in FIG. 2, in order to move in the small space, such as pipeline, the robot body 100 can comprise a snake head module 1001, a snake segment module 1002 and a snake tail module 1003 which all are electrically connected to each other in a sequential order. The snake segment module 1002 comprises a plurality of joint units 1022. The driving unit 110 disposed on the snake segment module 1002 includes one motor or a plurality of motors, and the motors are in series connection with a plurality of joint units 1022. For example, ten AI servo motors can be connected in series to enable five joint units 1022 to rotate with two degrees of freedom, that is, each joint unit can rotate left, right, up and down with 300 degrees, respectively, so that the snake segment module 1002 of the robot body 100 can have 10 degrees of freedom. Each joint unit 1022 is formed by assembling two AI servo motors and two u-shaped plastic frames crossing and perpendicular to each other, For example, the motor of the movable robot 10 can be an intelligent de servo motor with a model name DYNAMIXEL AX-12A, the communication protocol of the motor is a half duplex asynchronous serial port communication protocol, and the motor uses daisy chain series connection architecture, so that the motor circuit wiring at the robot end can be less complicated, and the snake-type robot body to do exercise can be more movable. For example, the robot body 100 can have a 15.3 kg-cm of torque and a rotational angle in a range of 0° to 300°, so that the snake-type robot body 100 can have better performance while moving within the pipeline. As shown in FIG. 3, the user can control action of the robot body 100 through the man-machine interface of the display device 20, and the display device 20 can transmit the rotational angle and revolving speed control instructions to the motor of the driving unit 110 through TTL sequence transmission manner, to control the action mode of the robot body 100.


When the snake tail module 1003 of the robot body 100 is not made by non-slip material, for example, the snake tail module 1003 is made by plastic, some non-slip pads can be pasted or attached under the bottom of the robot body 100 to provide friction for movement of the robot body 100; furthermore, the non-slip pads can also be pasted at left and right sides of the robot body 100 to prevent collision with the pipe wall when the robot body 100 is turned; furthermore, a balance pillar can be disposed under the bottom of the robot body 100 to improve balance and friction. For example, the user can apply 3D modeling software to design the balance pillar and the sample container and select PLA thermoplastic plastic material as material of the balance pillar and the sample container, and then operate a 3D printer to repeatedly stack the material to form the 3D objects.


The image capture unit 120 is disposed in the snake head module 1001 of the robot body 100. When the robot body 100 is in the moving state or static state, the image capture unit 120 can capture the image 121 in the space where the movable robot 10 locates, in an effective image capturing range. For example, the image capture unit 120 can be a video camera or other device having image capturing function, such as the video camera having maximum video resolution with 1920×1080 pixels, and maximum photograph resolution with 80 million pixels. Furthermore, the display device 20 can reconstruct the plurality of captured images 121, from the image capture unit 120, to form the actual pipeline route map. The display device 20 can compare a pre-stored pipeline plan route map with the actual pipeline route map, and display the comparison result; for example, the display device 20 can display residue on the pipe wall after liquid or gas is transported, or display corrosion state or disruption state on the used pipe wall.


In consideration of balance and spatial design of the snake robot, the sampling unit 130 can be disposed in the snake tail module 1003 of the robot body 100. When the robot body 100 is in the static state, the sampling unit 130 can perform the sampling operation on the pipe wall in the space to obtain remaining matter on the pipe wall as the sample 131, and the sample 131 can be analyzed to know whether there is poison gas, flammable gas, pollutant or corrosion dangerous to human health in the pipeline the sampling unit 130 can be a brush head electrically connected to a MG90S servo motor having the 2.0 kg of torque and the 0.11 s of speed under a 4.8 V voltage, and the rotational angle in a range of 0° to 180°, so that the brush head can be controlled to brush the bottom of the pipeline by a 120 degrees of angle or other angle, thereby obtaining sample 131. The manner of controlling the MG90S servo motor or other driving device to drive operation of the sampling unit 130 can be implemented by automatic control of the control unit 140 of the movable robot 10, or the user's remote control through the display device 20, or automatic control of the display device 20.


While the sampling unit 130 performs the sampling operation on the pipe wall, the display device 20 can displays the sampling condition of the sampling unit 130, which may be the amount, type, sampling times and sampling location of the sampling unit 130. The sampling condition can be adjusted according to length and width of the pipeline, the extension direction of the pipeline, or the transportation state of liquid or gas. In practice, the sample container can be designed to be quickly-detachable type, to protect the sample 131 obtained by the sampling unit 130 from being polluted. By using tenon design, the sampling brush head of the sampling unit 130 can be quickly replaced.


Optionally, the movable robot 10 further comprises a lighting unit such as a LED device disposed on the robot body 100; for example, the image capture unit 120 and the lighting unit both are disposed on the snake head module 1001. Within the pipeline, the robot body 100 usually moves under dark environment and the display device 20 is unable to clearly display the internal state of the pipeline, so the lighting unit can be used to light the space inside the pipeline to assist the operation of the movable robot 10; as a result, the image capture unit 120 can capture clear image, and the user can determine the sampling position according to the image 121 shown on the display device 20. In practice, the robot body 100 is provided with a lamp socket to facilitate to replace the lighting unit suitable for the space, so as to prevent the space from being too light or too dark. Preferably, the robot body 100 can have multiple lamp sockets to mount the lighting units having different brightness, and the control unit 140 is electrically connected to the lighting unit, to automatically turn on or off the lighting units with different brightness according to the automatic of the space where the robot body 100 locates.


The power supply unit 150 includes an AC-DC convertor, such as an electronic transformer, configured to convert AC power into DC power; for example, the AC-DC convertor can convert 110 v AC power into 12 v DC power, and then supply 12 v DC power to the AI servo motor of the driving unit 110, so that the AI servo motor can drive the snake segment module 1002 of the robot body 100, and the lighting unit. The image capture unit 120 applies 5v of voltage. Furthermore, the USB-TTL convertor of the display device 20 can be electrically connected to the power supply unit 150 of the robot body 100, and the power supply unit 150 of the robot body 100 can be electrically connected to other units included in the robot body 100, so that the power supply unit 150 can receive 5 V power from the display device 20 (such as PC) through the USB-TTL convertor (such as FTDI FT232R convertor), and provide power to other units included in the robot body 100, such as the control unit 140, and the MG90 motor for driving the sampling unit 130. Furthermore, the image capture unit 120 can receive 5V power from the display device 20. The voltage required by the units can be changed upon demand.


The display device 20 is electrically connected to the movable robot 10 for remote control. While the movable robot 10 acts, the display device 20 receives and displays the information associated with instructions and data of the units included in the movable robot 10. For example, the display device 20 can display the image 121 captured by the image capture unit 120 inside the pipeline, and mark the location where the sampling operation is performed, on the image 121 shown by the display screen, and simultaneously display the movement trace 210 of the robot body 100 in the space according to the plurality of driving instructions 111 of the driving unit 110.


Please refer to FIG. 4, which is a schematic view of a display interface of a display device of the map creation system of the present disclosure the display device 20 is installed with LabVIEW control program, as shown in FIG. 4, the display interface of the LabVIEW control program includes control options for a plurality of action modes, and the display device 20 uses the LabVIEW control program to transmit control instructions to the movable robot 10, so as to control the movable robot 10 to move according to the action modes, such as move forward, straighten, move backward, turn left, turn right, and collection, so as to perform above-mentioned operations. For example, the display device 20 can instruct the control unit 140 of the movable robot 10 to control movement of the robot body 100, and control the sampling unit 130 to sample.


The following describe the detail of using the display device 20 to control the movable robot 10 for map creation. First, a location where the movable robot 10 departs is set as an original point, and the movable robot 10 is controlled to move towards the end point. During movement of the movable robot 10, the display device can simultaneously display and record the movement points of the robot body 100 from the original point to the end point, on the bitmap 800, and display and record information generated during movement of the movable robot 10; for example, the information can be the sampling location of the sampling unit 130. The display device 20 can generate a movement trace 210 along which the robot body 100 moves in the space, according to all the movement points. The previous movement point and the current movement point are displayed by different the marks, for example, the previous movement points of the movable robot 10 are displayed by blue marks on the bitmap 800, and the current movement point of the movable robot 10 is displayed by a red mark on the bitmap 800, that is, the red mark indicates the location where the image capture unit 120 of the movable robot 10 captures the image; the location where the sample 131 is collected is displayed by a green mark; however, the description is mere for exemplary illustration, and the present disclosure is not limited thereto.


According to above-mentioned content, in a condition that the pipeline route map is unknown, the movable robot 10 can feedback the movement information to PC and the locations of the movable robot 10 are displayed and recorded on the bitmap 800 simultaneously, so that the movement trace of the movable robot 10 can be roughly formed based on the record of the bitmap 800. When the movable robot 10 is used to again explore the pipeline without the route map, the movable robot 10 can be controlled to move according to previous recorded movement trace.


When there is the actual pipeline route map, the display device 20 can simultaneously display the pre-stored pipeline plan route map, and the user can know the current location of the movable robot 10 according to the plurality of images 121 captured by the image capture unit 120 of the movable robot 10, and then operate the display device 20 to control movement the movable robot 10 according to the pipeline plan route map. Similarly, the recorded information can be used as reference for next movement in the same space.
