Description

Technical Field

[0001] The utility model relates to the technical field of mobile robots, in particular to a scientific research four-wheel drive robot. Background Art

[0002] With the rapid development of robotics technology, mobile robots have found widespread application in industrial production, scientific research, and teaching. Existing industrial robots typically have complex structures, consisting of a chassis, a body, and numerous functional components (such as a gimbal and camera). While this complex design can meet diverse functional requirements, it also presents challenges such as bulk, high cost, and difficult maintenance. For example, Chinese patent publication CN211442545U discloses a mobile robot chassis with an independent steering wheel assembly. While this chassis offers advantages such as flexible steering and strong obstacle-crossing capabilities, it primarily provides only locomotion. To implement other functions, the chassis requires a body, a nose, and other expandable functional modules, which can be expensive. Furthermore, some robots have fixed bodies, making them inconvenient to disassemble for maintenance. Applications in scientific research and teaching require even higher practicality for mobile robots. Researchers require a simple, easily modifiable platform for conducting various experiments and validating algorithms, while also ensuring a stable, complex, and cost-effective structure. However, existing mobile robots either have single functions or complex and fixed structures, which makes it difficult to meet the diverse needs of scientific research and teaching.

[0003] Therefore, there is an urgent need to develop a four-wheel drive robot that is multifunctional, scalable, and suitable for scientific research and teaching to solve the problems existing in the existing technology. Utility Model Content

[0027] The chassis 1, serving as the robot's foundational support structure, features a box-like design with a sunken center section and several independent wheel wells around its perimeter for mounting the steering wheel assembly. A debugging port 101 is reserved at the front of the chassis for further product development.

[0028] This robot is primarily intended for scientific research, teaching, and laboratory applications. It can perform multiple functions, including remote control, video capture, and external power supply, and is also capable of secondary development. Unlike industrial robots, this research four-wheel drive robot undergoes secondary development of the robot chassis, discarding the complex body and head structure. Instead, it incorporates a single upper cover, upon which a pan / tilt head 4, a remote control camera 5, a waterproof socket 6, a computer stand 7, and an inverter 8 are mounted. This simplifies the robot's structure and makes it easier to disassemble and assemble new modules. Furthermore, a debugging port 101 on the chassis facilitates connection to external data acquisition. This research four-wheel drive robot boasts a simple structure, low cost, and convenient maintenance and replacement of functional modules. It also facilitates secondary development by researchers, offering high flexibility, scalability, and customization capabilities to meet the needs of various scientific experiments. Therefore, it is primarily designed for scientific research, teaching, and laboratory applications.

[0029] In this embodiment, the upper cover 2 adopts a flip-top design, including a cover plate and an inverter cover 202. The cover plate and the inverter cover 202 are integrally formed. The inverter cover 202 protrudes upward to form a trapezoidal cavity. One end of the cover plate is rotatably connected to the chassis 1 through two hinges 3 to facilitate maintenance and modification of the internal structure of the robot. The upper cover 2 is provided with multiple functional mounting holes and structures, including: a hinge mounting hole 201 for installing a hinge, which is located on the side of the upper cover 2; a remote control camera mounting hole 203 for installing a remote control camera 5, which is located on the back of the inverter cover 202; a pan / tilt mounting hole 204 for installing a pan / tilt 4, which is located on the top surface of the inverter cover 202; a heat dissipation hole 205 for equipment heat dissipation, which is located on the side of the inverter cover 202; a waterproof socket mounting hole 206 for installing a waterproof socket 6, which is located above the heat dissipation hole 205; a computer stand mounting hole 207 for installing a computer stand 7, which is located in front of the inverter cover 202; a reserved modification structure mounting hole 208, which is convenient for later function expansion and is set on one side of the computer stand mounting hole 207; a remote control antenna mounting hole 211 for installing a remote control antenna, which is located on the top surface of the inverter cover 202, on one side of the pan / tilt mounting hole 204. In addition, a reinforcing rib 210 is provided on the bottom surface of the upper cover 2 to improve the overall strength of the upper cover.

[0030] The pan-tilt head 4 is installed at the pan-tilt head installation hole 204 of the upper cover 2, and can realize horizontal 360-degree rotation to adjust the shooting angle of the camera 5. The pan-tilt head 4 is driven by a servo motor to ensure smooth rotation and accurate positioning.

[0031] The remote control camera 5 is mounted at the remote control camera mounting hole 203 and works in conjunction with the pan / tilt head 4 to enable remote video capture and real-time monitoring. The camera 5 uses a high-definition image sensor, has night vision capabilities, and is waterproof to ensure normal operation in complex environments.

[0032] The waterproof socket 6 is installed at the waterproof socket installation hole 206 and is used to connect an external device to power the robot or to power the external device through the inverter 8.

[0033] The computer bracket 7 is installed at the computer bracket installation hole 207 and is used for installing an industrial computer or a laptop computer.

[0034] The inverter 8 is mounted on the inverter mounting bracket 209 and protected by the inverter cover 202. The inverter 8 can convert direct current into alternating current to provide standard AC power for external devices.

[0035] The working principle and usage of this scientific research four-wheel drive robot are as follows: First, the robot is powered on using the pre-installed operating system. The system automatically performs a hardware self-check to ensure that all functional modules are functioning properly. The operator can control the robot's movement using a remote control device. The chassis 1 features independent steering wheels, each of which can rotate 360 ​​degrees, enabling flexible omnidirectional movement. Furthermore, the independent suspension system ensures stable operation on complex terrain.

[0036] Then, the PTZ 4 and remote control camera 5 system are started, and the angle of the PTZ 4 can be adjusted in real time through the remote control interface to obtain video images in different directions. The image data collected by the camera 5 can be transmitted to the control terminal in real time via the wireless network, and can also be stored in a local storage device.

[0037] Second, waterproof socket 6 connects to external devices to power the robot. If powering external devices is required, AC power can also be output through waterproof socket 6. Inverter 8 automatically adjusts output power based on load conditions and provides overload protection. Furthermore, for users who require secondary development, hardware expansion or software development can be performed through the reserved debug port 101 on chassis 1. This robot's system includes standard communication and control interfaces, supporting multiple development languages ​​and protocols.

[0038] Throughout the entire operation process, the heat dissipation holes 205 continue to work, ensuring that the operating temperature of each functional module remains within a safe range. The operator can view the robot's operating status in real time through the remote monitoring interface, including key parameters such as battery power, motor temperature, and communication status.

[0039] After use, shut down all functional modules according to standard procedures to ensure data is correctly saved, and finally turn off the power of the entire machine. Regular maintenance should also be performed on the robot, including checking the tightness of all connections and cleaning dust from important areas such as the heat dissipation holes 205.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Any innovative improvement or replacement based on the present invention shall fall within the scope of the claims of the present invention. At the same time, the various parameters, materials, and processes mentioned in the above embodiments are not exclusive. Without departing from the technical essence of the present invention, ordinary technicians in this field can make various alternatives, and these alternatives should also be considered to fall within the scope of protection of the present invention.
