The present invention discloses a mobile unit, an inventory management system, and a method for mobile unit localization. Sensors are immovably disposed in the workplace, actively identifying the positions of the mobile units. The individual sensor disposed in the workplace can monitor the positions of a plurality of mobile units simultaneously, and the number of sensors is only related to the size of workspace, which is independent of the number of mobile units. Since no complicated position calculations are needed for the mobile units, it reduces the requirements for on-board processors, which is more advantageous to monitor the preexisting non-automated vehicles or retrofit them into automated vehicles. With the method of the present invention, position calculations are not carried out on the bodies of AGVs, the requirements for the on-board controllers of AGVs are low, and it is easier to retrofit the non-intelligent mobile units, and thereby position monitoring and autonomous operation are implemented.

The present invention discloses a safety protection method of dynamic detection for mobile robots. The mobile robot is provided with a sensor. Said sensor obtains the obstacle information in the detection areas in front of a mobile robot, and the mobile robot is caused to progressively slow down and dynamically adjust the detection area when an obstacle appears in the detection area. If no obstacle is detected in the detection area after adjusting, then the mobile robot is caused to keep on moving, and if an obstacle is still detected in the detection area after adjusting, then the mobile robot is caused to keep on decelerating until they are stopped. The sensor sets different detection areas according to the traveling speed and traveling direction of the mobile robot, or presets the detection area according to the path and dynamically adjusts it when the mobile robot is running. The safety protection method of dynamic detection for mobile robots of the present invention enables a mobile robot to pass through a path with many obstacles, having good capability of anti-interference and meanwhile ensuring the consistency of the detection range and processing mechanism at curved and linear paths.

The present invention discloses a AP switching method for mobile robots based on path setting, including the following steps: install APs in the application environments of mobile robots; control the mobile robots to move along established routes, record the signal strengths of each of the APs on each of the paths of the mobile robots, and determine the AP with the strongest signal strength on each path; configure the MAC addresses of the APs to be connected on each path whereon the mobile robots will move; the mobile robots monitor continuously whether the AP that is connected at the moment coincides with the AP configured for the current path, if not, then switch to the configured AP directly. The present invention can avoid effectively the problem of switching APs excessively frequently, the method is simple and effective, without the need for setting thresholds for signal strengths, and it can decrease uncertainty effectively, which is valuable in the application environments of mobile robots.

A self-charging device for mobile robots, which includes a charging cradle and a charging pin, the charging cradle includes a charging contact and a first elastic member connected with the charging contact. The charging pin is used to contact the charging contact for charging. Preferably, the charging cradle also includes a buffering block, a second elastic member and a mounting enclosure. The charging contact is connected with the buffering block through the first elastic member. The buffering block is provided encircling inside the mounting enclosure. One end of the second elastic member is connected with the buffering block, and the other end is connected with the mounting enclosure. The self-charging device for mobile robots is capable of counteracting the deviation angle due to the misalignment when the mobile robot is charging, and buffering the impact force produced when the charging contact docks with the charging pin.

A path planning method is provided for mobile robots, including the following steps: Step 1. Searching for available paths according to the destinations of moving of the robots and the nodes properties on the map; Step 2. Determining the optimum path, according to the weights of the segments on all the available paths, with the segments being arbitrary curves made up of Bezier curves or splined curves of a plurality of control points; and Step 3. Driving the robots to move along the optimum path, and to stop at the stop points. The present path planning method for mobile robots increases the ways of connection between the nodes significantly and avoids that there is only a single way of connection between two nodes.
