Description

Technical Field

[0001] The present application relates to the field of minimally invasive medical robots, and in particular to a low-noise and low-inductance micro-robot connecting cable. Background Art

[0002] With the continuous innovation in the field of micro-robots at home and abroad, the domestic data collection robot industry is entering a stage of rapid development. Its application prospects are reflected in: industrial upgrading and intelligent development. The application prospects of data collection robots in digital transformation are very broad, bringing new opportunities for industrial upgrading and intelligent development in various fields. Data collection robots can accurately locate and perform emergency rescue through real-time monitoring and data analysis of specific harsh environments.

[0003] At the same time, in urban management, data collection robots can support the construction of smart cities. For example, by collecting traffic flow, it is possible to predict traffic congestion and optimize the intelligent navigation system, thereby improving the efficiency of urban traffic operation.

[0004] The data formats and communication protocols between different data collection robots are diverse, which makes data integration difficult. Secondly, the storage and transmission of large amounts of data also put forward requirements for data collection equipment. In order to meet these challenges, it is advisable to adopt a variety of strategies. On the one hand, choose standardized equipment and communication protocols to achieve data interoperability. On the other hand, using cloud computing and big data Beidou navigation and positioning technology, efficient storage and analysis of massive data can be achieved.

[0005] The application of data collection micro-robots in digital transformation is very optimistic. With the continuous development of modern information and intelligence and drone reconnaissance technology, data collection robots will become more intelligent and efficient. In the future, they are expected to be fully applied in high-tech fields to promote digital innovation and development in all walks of life. Through real-time data collection, refined analysis and intelligent decision-making support, data collection robots have brought huge opportunities for change to society and human development, helped industrial upgrading and intelligent development, and created more economic value and comprehensive benefits for society.

[0006] Micro data collection robots can collect data in supervision, micro manufacturing and specific natural disasters. They are small in size, but are equipped with all the equipment needed for movement, communication and data collection. Their more special function is that they can generate energy for their own activities through solar panels. These micro robots can collect and transmit data using a circuit board. They use surface mount technology and use conductive adhesives to bond accessories to a flexible double-sided printed circuit board. A solar cell that can generate 3.6V voltage can fully support the energy required for the micro robot to walk and realize an autonomous intelligent robot that can operate at the micro level. Therefore, it has a disruptive technological revolution.

[0007] At present, high-end enterprises and research institutes in the domestic robot industry are working hard to control solar cells to provide energy for micro-robots. If this type of micro-robot is to be mass-produced efficiently, the key lies in accurate and fast signal transmission, so the development of special micro-robot cables still has a long way to go.

[0008] As a micro data collection robot, especially when used in natural disasters, the data collection robot cable, which is the key output of audio signals in environmental detection, is an important decision-making basis for troubleshooting dangerous situations. The biggest problem with the current micro data collection robot connection cables is that the noise and inductance values ​​are too large, which often brings serious troubles to earthquake relief and endangers the lives of victims.

[0009] The cable products used in these data collection micro-robots have unreasonable functional design schemes such as torsion, vibration, impact, and heat dissipation structure, and there is insufficient selection of design materials for high and low temperature changes; at the same time, there is a lack of consideration in terms of sheath protection / contact inductance. Secondly, the specific environmental requirements for salt spray resistance and acid and alkali resistance are not considered in the application environment.

[0010] Therefore, the project of developing a micro data acquisition robot cable with extremely low noise and extremely low inductance is of great significance for the high-precision operation of micro robots, and has high scientific and technological innovation value and application value for ultra-long-term working of intelligent equipment.
