Description

technical field [0001] The invention relates to the technical field of intelligent robots, and more specifically relates to an interface expansion board based on a TX2 core board. Background technique [0002] In today’s life, NVIDIA released a new generation of JetsonTX2 development kit in March 2017. The JetsonTX2 development kit is currently the best solution for developing terminal applications for artificial intelligence. It uses a combination of core board + interface expansion board. . The official interface expansion board provides some interfaces supported by the core board that meet the basic development needs, but cannot meet the interface requirements required for the actual product development of the fire robot. Because the fire robot is used in a special scene, and has subsystems such as variable speed control, water cannon, pan-tilt, and swing arm, the main control module needs to have sufficient interfaces to interconnect and control these subsystems.

AI Technical Summary

Problems solved by technology

Therefore, we need 3 USB3.0 interfaces and microUSB interfaces. Neither the official public board nor the existing expansion boards based on the TX2 core board of other manufacturers are available for use, and there is no related development plan.

In addition, 2 CAN interfaces and 3 UART interfaces are required to meet the needs of fire-fighting robots. These requirements cannot be met by various boards on the market.

[0005] In summary, the existing TX2 interface expansion board supports insufficient interfaces, incomplete functions, uncompact structure, unnovel forms, large size, inconvenient use, and cannot meet the interface requirements required for the actual product development of fire-fighting robots.
