An autonomously moving transport system for transporting pallets and/or pallet cages, wherein the transport system comprises a pick-up apparatus for picking up the pallet and/or the pallet cage, wherein the transport system comprises a drive unit and a control apparatus, wherein the control apparatus comprises a data processing unit and an obstacle recognition device having a first sensor unit, wherein the first sensor unit is configured to generate a monitored field in order to examine a free placement area for the pallet and/or the pallet cage between other pallets and/or pallet cages for obstacles, wherein the control apparatus is configured to control the drive unit such that the transport system, in the absence of an obstacle, adopts a placement operating mode and moves the pallet and/or the pallet cage into the free placement area for placement, characterized in that in the placement operating mode: a) the obstacle recognition device is configured to deactivate the monitored field or not to output an obstacle recognition signal during the travel over the free placement area, at least until the placement of the pallet and/or the pallet cage on the free placement area; or b) the data processing unit is configured to ignore an obstacle recognition signal of the obstacle recognition device during the travel over the free placement area, at least until the placement of the pallet and/or the pallet cage on the free placement area. wherein the transport system comprises a drive unit and a control apparatus, wherein the control apparatus comprises a data processing unit and an obstacle recognition device having a first sensor unit, wherein the first sensor unit is configured to generate a monitored field in order to examine a free placement area for the pallet and/or the pallet cage between other pallets and/or pallet cages for obstacles, wherein the control apparatus is configured to control the drive unit such that the transport system, in the absence of an obstacle, adopts a placement operating mode and moves the pallet and/or the pallet cage into the free placement area for placement, characterized in that in the placement operating mode: a) the obstacle recognition device is configured to deactivate the monitored field or not to output an obstacle recognition signal during the travel over the free placement area, at least until the placement of the pallet and/or the pallet cage on the free placement area; or b) the data processing unit is configured to ignore an obstacle recognition signal of the obstacle recognition device during the travel over the free placement area, at least until the placement of the pallet and/or the pallet cage on the free placement area. a) the obstacle recognition device is configured to deactivate the monitored field or not to output an obstacle recognition signal during the travel over the free placement area, at least until the placement of the pallet and/or the pallet cage on the free placement area; or b) the data processing unit is configured to ignore an obstacle recognition signal of the obstacle recognition device during the travel over the free placement area, at least until the placement of the pallet and/or the pallet cage on the free placement area.
