The promotion and use of new energy vehicles is an important deployment to implement the national dual-carbon development strategy. China's new energy vehicles are growing explosively, and the construction of charging piles is the basic guarantee for the healthy development of the industry. However, the lack of charging piles, low utilization efficiency, poor intelligence and other restrictions hinder the development of new energy vehicles. The team used flexible arm robot control, identification, positioning technology, Internet of Things technology, etc., to develop a flexible arm-based self-charging and self-unloading intelligent shared charging robot system. It has the characteristics of strong space adaptability, high flexibility of flexible arm telescopic operation, accurate positioning of charging interface and high tolerance.
