[0032] To make the technical problems, technical solutions, and advantages of this application clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0033] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0034] This application addresses the limitations of field of view of roof-mounted cameras in existing technologies and the safety issues associated with installing various travel devices on the roof of a car. Embodiments of this application provide a mechanical control system and a car. The mechanical control system utilizes a robotic arm control component to adjust the height of the roof-mounted camera and also to fix items placed on the roof.

[0035] Reference Figure 1 As shown, this application provides a mechanical control system, including:

[0036] Car roof 1;

[0037] The robotic arm control component 2 is disposed on the outer surface of the car roof 1 and is electrically connected to the car's in-vehicle control platform (not shown in the figure); the robotic arm control component 2 includes at least a number of interconnected robotic arms and a robotic hand, the robotic arms and the robotic hand are connected, and a camera module is disposed at the connection position;

[0038] The in-vehicle control platform is used to control the operation of the robotic arm, the robotic hand, and the camera module.

[0039] In this embodiment, a robotic arm control component 2 is provided on the car roof 1. The robotic arm control component 2 is electrically connected to the in-vehicle control platform inside the car. The robotic arm control component 2 is equipped with a camera module, which can be a camera, radar, etc. The in-vehicle control platform can send corresponding control commands to the robotic arm control component 2 to control the lifting, fixing and other actions of the robotic arm. The in-vehicle control platform can also send fixing commands to the robotic arm control component 2 to fix items placed on the car roof 1.

[0040] Since autonomous driving requires observing various road conditions, installing cameras and lasers on the roof limits the field of vision. Therefore, this application proposes installing a robotic arm control component 2 on the roof to fix or move its position, facilitating observation of the vehicle's surroundings and enabling autonomous driving to better detect and process surrounding conditions in a timely manner.

[0041] On the other hand, installing various travel equipment on the roof of a car, such as boats, tents, bicycles, or other objects, or placing suitcases containing various equipment, including tents and inflation valves, would be cumbersome and pose safety risks, potentially leading to falls and injuries. Furthermore, when retrieving drones from a car, a robotic arm is needed to retrieve the drone and assist in its relaunch. This application provides a robotic arm control component 2 that can be portablely installed anywhere on the car's roof. When needed, the camera module within the robotic arm control component 2 is raised using the in-vehicle control platform to observe the surrounding environment. Because the robotic arm can be raised to a higher position, a more comprehensive and unobstructed observation range and distance can be obtained, allowing for better use of autonomous driving functions.

[0042] The roof needs to be fitted with rectangular boxes for storing bicycles, kayaks, tents, and various other items. However, due to the relationship between the car and the person, it is very inconvenient to place and retrieve these items. It is also necessary to climb onto the roof to secure or remove various items. By using the in-vehicle control platform to control the robotic arm control component 2, objects can be lifted, placed in a suitable position, and secured. At the same time, if it is necessary to remove an item, the robotic arm can be used to release the fixing bracket and retrieve the item to a position that is at least convenient for a human to catch.

[0043] The robotic arm in this application can be composed of three to five segments, similar to a human arm, including an upper arm, forearm, hand, and fingers. Alternatively, it can be composed of two, four, or five segments. Two segments include the arm, hand, and fingers, while four or five segments include the upper arm, middle arm, forearm, forearm, and hand. The hand shape can resemble a human hand or a gripping joint with three, four, or five fingers.

[0044] The aforementioned boom is connected to the roof of the vehicle and is made of lightweight alloys such as aluminum alloy or titanium alloy, or carbon fiber. The weight of the entire roof-mounted robotic arm does not affect the uniform distribution of the overall vehicle weight.

[0045] The robotic arm is able to reach any part of the vehicle roof with its hand and perform maneuvering operations.

[0046] Specifically, refer to Figure 2 As shown, the robotic arm control component 2 includes:

[0047] The base 21 is vertically disposed on the outer surface of the car roof 1, and the entire base 21 can rotate along the center line of the base 21. A first motor is disposed inside the base 21.

[0048] The first robotic arm 22, the second robotic arm 23, the third robotic arm 24, and the fourth robotic arm 25 are interconnected. Each robotic arm includes a motor assembly, and one robotic arm containing the motor assembly is correspondingly connected to another robotic arm that does not contain the motor assembly. The end of the first robotic arm 22 that does not contain the motor assembly is connected to the first motor, which drives the first robotic arm 22 to rotate about the axis of the first motor.

[0049] Robotic arm assembly 26, which is connected to the end of the fourth robotic arm 25 that does not contain the motor assembly.

[0050] Among them, the robotic arm component 26 has translational and rotational degrees of freedom in three-dimensional space X, Y, Z. It is mainly composed of 6-7 rotary motors on the robotic arm body and corresponding rotary arms. Through the 6 rotary motors, the robotic arm can assist in grasping any object on the roof of the vehicle in three-dimensional space.

[0051] In this embodiment, each robotic arm is equipped with a rotatable motor assembly. Preferably, four robotic arms are provided: a first robotic arm 22, a second robotic arm 23, a third robotic arm 24, and a fourth robotic arm 25, all interconnected. The end of the first robotic arm 22 without the motor assembly is connected to a first motor internally mounted on the base 21. The end of the first robotic arm 22 containing the motor assembly is connected to the second robotic arm 23. Both the first motor and the motor assembly are rotatable motors. Each robotic arm can rotate axially relative to the connected motor. The robotic arm assembly 26 can be connected to the end of the fourth robotic arm 25 without the motor assembly.

[0052] Each robotic arm in the robotic arm control assembly 2 is electrically connected to the in-vehicle control platform, which can individually control the working movements of each robotic arm.

[0053] Specifically, Figure 2 The diagram shows a robotic arm design with higher degrees of freedom and a smaller footprint. The base 21 is fixed to the car roof 1, and the first motor within the base 21 can rotate perpendicular to the car roof 1, i.e., rotate perpendicular to the roof plane. The first robotic arm 22 rotates perpendicular to a plane parallel to the car roof 1. The second robotic arm 23 rotates around a line parallel to the roof plane as its center line. The third robotic arm 24 rotates around a line parallel to the roof plane as its center line. The fourth robotic arm 25 rotates along a line perpendicular to the roof plane. The robotic hand assembly 26 consists of five fingers (two joints for the thumb and three joints for the other fingers) capable of gripping and holding the object to be fixed.

[0054] Furthermore, a camera module 27 is provided at the end of the fourth robotic arm 25 that does not contain the motor assembly; the camera module 27 is used to collect working image data of the robotic arm assembly 26.

[0055] In this application, the camera module 27 is set on the end of the fourth robotic arm 25 that does not contain the motor assembly. That is, the camera module is set on the arm hand. The camera module 27 is used to observe the position of the robotic arm assembly 26 at any time and perform various grasping and closing operations.

[0056] For example, cameras and lidar, whether handheld or fixed to a robotic arm, can provide the clearest and most reasonable images for autonomous driving by adjusting their height, position, and orientation. This is especially useful on mountain roads and paths with cliffs or half-mountains. The camera and lidar positions can be adjusted appropriately to identify dangerous locations and to directly construct images of relatively safe locations.

[0057] By focusing on dangerous locations, the safety of vehicle driving control can be improved. When parking is required, for example, a robotic arm can observe the parking position around and record the location of obstacles on the map, which can improve the accuracy of automatic parking. At the same time, it can also provide the driver with reasonable parking space search, such as quickly finding a parking space.

[0058] Optionally, cameras can be installed on each robotic arm to monitor whether there is any potential interference with the placed objects.

[0059] Furthermore, since the camera module 27 is used to collect working image data of the robotic arm assembly 26 and send it to the in-vehicle control platform, this application allows the camera module 27 to observe the arm's activity inside the vehicle and direct the movement of each arm. By observing the position of the arm's camera, and to prevent interference, an unobstructed running trajectory for the robotic arm is formed inside the vehicle. This is mainly achieved by the arm control chip, combined with the interference objects observed by the camera, to determine the arm's running trajectory and running time, ultimately reaching the designated position, and then the robotic arm head completes the final action.

[0060] Furthermore, the robotic arm assembly 26 includes:

[0061] Multiple mechanical fingers 261 are electrically connected to the in-vehicle control platform;

[0062] The connecting rod 262 is inserted into the connector 251 of the fourth robotic arm 25.

[0063] Specifically, the surface of the mechanical finger 261 is made of a skin-like, wear-resistant material.

[0064] In this embodiment, the arm gripping module addresses the issue that objects on the vehicle roof may not maintain a fixed position on the mounting rack. Therefore, during operation, multiple mechanical fingers 261 are used to act as grippers, fixing and maintaining the object's position to prevent it from falling. Simultaneously, the robotic arm's camera continuously tracks the surrounding environment to detect any over-limit situations that prevent the vehicle from passing, issuing timely warnings to prevent collisions. This application primarily consists of a multi-segment arm and a hand. The multi-segment arm can have 2-6 segments, and the hand mimics a human hand, with a skin-like material on the surface that is wear-resistant and corrosion-resistant.

[0065] Optionally, the system further includes:

[0066] Sensor sensing component 3 is installed around the vehicle body and connected to the in-vehicle control platform.

[0067] In this embodiment, multiple sensor sensing components 3 are also installed around the vehicle body. These components may include six cameras and twelve ultrasonic radars around the vehicle body, as well as a variable RGBD binocular, monocular, or lidar sensor on the roof. RGBD (Red-Green-Blue Depth) is an image or data format that combines color (RGB) and depth (Depth) information. RGBD images are captured by a camera with depth sensing capabilities. This application utilizes the data collected by the multiple sensor sensing components 3 to transmit it to the in-vehicle control platform.

[0068] Optionally, the in-vehicle control platform is located in the vehicle's human-machine interaction system (not shown in the figure); the in-vehicle control platform is used to send decision commands to the robotic arm control component 2; the robotic arm control component 2 completes the corresponding work tasks according to the decision commands.

[0069] In this embodiment, integrating the in-vehicle control platform into the human-machine interaction system saves space within the vehicle. The in-vehicle control platform includes a data fusion module, which transmits data collected by multiple sensor sensing components 3 to the data fusion module. This includes: processing different data formats directly within the sensor sensing module; and converting the unique data formats of the LiDAR and camera into a common data format, ensuring consistency in the data format reaching the data fusion module. This allows for rapid fusion during the fusion phase, achieving BEV perception. BEV perception refers to the technology of perceiving the environment from a bird's-eye view (BEV). This technology converts image sequences from multiple perspectives into BEV features, thereby achieving comprehensive perception of the surrounding environment. BEV perception has wide applications in autonomous driving, intelligent transportation, and other fields, providing more comprehensive and accurate environmental perception information and helping to overcome the limitations of traditional monocular and binocular vision perception technologies in terms of scene perception range, blind spots, and posture changes. Another approach involves converting the different data formats to the data fusion module.

[0070] The data fusion module of this application receives data from multiple sensor sensing components 3, performs preliminary data format unification, then performs post-fusion, and promptly feeds the fused image into the large neural network model embedded in the vehicle control platform for data processing, forming various different markers, such as vehicles, traffic lights, lane lines, etc. The lidar and camera on the roof, due to their variable positions, need to be matched with data from other cameras in real time to expand the field of view after data fusion, which can better assist vehicle operation.

[0071] This application can also embed perception data into a large model within the in-vehicle control platform, enabling vehicle control and execution of functions such as lane keeping, lane changing, speed shifting, and stopping at traffic lights through control and execution strategies. Alternatively, it can be unified with a large neural network model to form an end-to-end integrated perception and decision-making execution system, achieving fully human-like autonomous driving.

[0072] Furthermore, refer to Figure 1 and Figure 4 As shown, a placement area 4 is formed on the car roof 1, and the robotic arm control component 2 is disposed within the placement area 4.

[0073] Specifically, the placement area 4 is also provided with at least two track fixing components 5, which are used to place bicycles or similar objects to be fixed; the robotic arm control component 2 is used to fix the bicycles or similar objects to be fixed in the track fixing components 5.

[0074] This application allows for the installation of a rooftop luggage compartment within the placement area 4. The luggage compartment can be opened using a robotic arm control component 2. The placement area 4 is also equipped with at least two track fixing components 5 for placing bicycle-like items. The luggage compartment can also slide along the two track fixing components 5 to prevent damage to the roof.

[0075] In summary, the system of this application can achieve the following effects:

[0076] (1) Controlled by the in-vehicle control platform, such as through the screen interface. Taking a bicycle as an example, its center position can be placed on the robotic arm. By controlling the robotic arm, the bicycle can be placed on the roof of the vehicle and fixed on the bicycle track on the vehicle through the bottom track fixing device. Then, the bicycle can be fixed in the vertical direction by the robotic arm or human hand.

[0077] (2) Place the luggage in the luggage compartment on the vehicle. The robotic arm can be used to open the luggage compartment on the roof. Then the luggage can be given directly to the robotic arm, which will take the luggage and place it in the luggage compartment on the roof. Then the luggage compartment will be closed and locked.

[0078] (3) The kayak is fixed on the roof of the vehicle. The kayak is lifted to the roof by a robotic arm and fixed on the fixed frame. Then it is locked. When taking the kayak, the fixed lock is released, the kayak is taken out, and the kayak is lifted down as far as possible so that it can be caught by hand or placed on other supports.

[0079] (4) For autonomous driving, a robotic arm can be used to grab cameras and radar, reach a certain height on the roof of the vehicle, obtain the perception of objects around the vehicle through cameras and radar, form a bird's-eye view with the cameras around the vehicle, and perform autonomous driving control through a large neural network model.

[0080] (5) The robotic arm can be controlled by a mobile phone to assist human hands and make flexible use of the robotic arm to help cars and passengers solve various technical problems. For example, in the event of a car accident, if the car door cannot be opened, the robotic arm can be used to break the window and pull people out. Or in dangerous situations, such as when a car behind hits a car in front, the robotic arm can act in time to stop the car behind.

[0081] This application also provides a vehicle, including, as described in the embodiments. Figures 1 to 4 The mechanical control system described herein.
