The application discloses a reliable navigation auxiliary grabbing execution method of a resource-limited
mobile robot, relates to the technical field of navigation auxiliary grabbing, and comprises the following steps: when a
robot receives a navigation target, starting a navigation and map module, activating a positioning and navigation module, and detecting in real time; after reaching the navigation target, entering an observation stage, activating a detection module, and acquiring a target bounding box and depth; in the approaching stage, the target center pixel and depth are used to control the mobile
chassis until the lateral error, distance and depth stability meet the grabbing readiness conditions; in the grabbing stage, a mechanical arm grabbing sequence is run, and whether the object has been reliably grabbed is judged according to the feedback after grabbing; if a fault occurs in the navigation stage, the observation stage, the approaching stage or the grabbing stage, a
recovery action associated with the failure stage is selected, the task is continuously executed until the grabbing
verification is successful after the
recovery is successful, and the task is ended. The application greatly improves the task success rate and effectively enhances the
system robustness and reliability without introducing a new module.
