Publication number: 20240092579Abstract: A container conveying system including a controller, a first robot, and/or a second robot. A first container pickup mechanism is provided on the first robot. A second container pickup mechanism is provided on the second robot. The controller is configured to, in response to a container conveying request, send a first conveying instruction to the first robot if it is determined a target container to be conveyed based on the container conveying request has a size within a first size range; or send a second conveying instruction to the second robot if it is determined the target has a size within a second size range. In warehousing operation scenarios, by jointly using the two robots for operation, containers with various container sizes can be picked up and placed, thus improving utilization rate of a container storage space.Type: ApplicationFiled: January 21, 2022Publication date: March 21, 2024Inventors: Kai LIU, Qiming WANG, Zhihui QIN, Nan ZHANG, Yuhui XIAO, Xiaowei LI, Xi CHEN, Pengfei WANG
