Transport robots

Abstract

Transport robot comprising: a main control and processing unit (110), a pick-up and drop-down mechanism (120), and a marker detection unit (130); wherein the robot body operates at a storage area level, with storage racks for storing storage containers being provided in the storage area, wherein the marker detection unit (130) is arranged on the pick-up and drop-down mechanism (120); wherein the main control and processing unit (110) is configured to control the robot body to move to a first horizontal position and to control the pick-up and drop-down mechanism (120) to move to a first vertical position according to the target access position information of a target storage container;the marking detection unit (130) comprises a marking detection device and / or an edge detection device, wherein the marking detection unit is configured to detect a target storage position marking placed at a target storage position in a field of view encompassing the target storage rack by means of a marking detection device and / or to detect at least two target container edges of the target storage container in the field of view encompassing the target storage rack by means of the edge detection device;the main control and processing unit (110) is further configured to calibrate a position of the pick-up and put-down mechanism (120) according to a position of the target storage position marker and, after completion of the calibration, to place a transported target storage container at the target storage position on the target storage rack, or wherein the position of the pick-up and put-down mechanism is calibrated based on the position of the target storage position marker and / or the positions of the at least two target container edges and, after completion of the calibration, the target storage container placed therein is removed from the target storage position of the target storage rack.
