Connection scheme between the main controller and motor of a sweeping and mopping robot

The domestic mainstream brand of robot vacuum cleaners are equipped with built-in travel motors, roller brush motors, and LiDAR modules. The devices continuously vibrate, the internal motors generate heat, and the original connectors, due to long-term operation, experience intermittent power failures and loss of radar signals, leading to a high after-sales failure rate. The production line aims for automated assembly and requires support for SMT (Surface Mount Technology) chip placement.
