The application discloses a robot map updating method, which comprises the following steps: step 1, a robot establishes a current map in a current environment; step 2, the current map is updated according to the angle relationship between the current map and a map stored in a historical map library last time, the updated current map is stored in the historical map library, and the updated current map is updated as the map stored in the historical map library last time, so that the current map established in step 1 is updated; wherein each frame of map stored in the same historical map library represents the current environment.

The utility model discloses new energy micro -car quick exchange frame, including frame, the frame is formed by the beam, stringer in proper order and enclose the connection, and the battery body moves from the bottom end of frame to the inside of frame, the inside wall of relative stringer is intervally provided with a plurality of muscle strip no.

The utility model discloses a polishing device for metal cutter processing, including cutter positioning module, flexible clamping module, material conveying module and polishing execution module. Cutter positioning module includes the spacing unit and linkage adjusting mechanism of symmetrical setting, and linkage adjusting mechanism passes through the synchronous adjustment clamping interval of spacing unit through two -way screw thread transmission subassembly, and the adaptation different width cutter. Flexible clamping module is located at the working surface of spacing plate, including elastic deformation layer and rolling body array, and the surface damage of cutter is reduced through rolling contact, and the cutter is allowed to convey steadily under the clamping state. Material conveying module adopts horizontal conveyer, and is through between spacing unit, ensures that cutter is continuously stable conveying. Polishing execution module includes rotary driver and polishing wheel group, and the cutter is polished efficiently. The device is through the combination of adjustable clamping, rolling support and continuous conveying, realizes the accurate positioning and efficient polishing of cutter, improves the processing precision, and is suitable for the automatic processing of cutter.
