A surface of the outer shell includes a first part and a second part, and a height deviation locates between the first part of the surface and the second part of the surface toward a normal direction of the surface. The handle tube is located between the first part of the surface and the second part of the surface, and a part of a handle of the movable container is embedded in the handle tube. The case covers the handle tube and attaches to the surface via an attachment mechanism. ## Claims ### Claim 1 A movable container, comprising: an outer shell, wherein a surface of the outer shell comprises a first part and a second part, and a height deviation locates between the first part of the surface and the second part of the surface toward a normal direction of the surface; a handle tube, extending outwardly from the second part of the surface and located between the first part of the surface and the second part of the surface, wherein a part of a handle of the movable container is embedded in the handle tube; and a case, detachably attached to the handle tube and the second part of the surface of the outer shell via an attachment mechanism, wherein the case is arranged to accommodate a detachable battery providing current; a sensing device, driven by the current from the detachable battery, including: an image sensor, positioned on the handle and arranged to sense a distance feature and a recognition feature, wherein the movable container uses the distance feature and the recognition feature to follow a target; and a proximity sensor, arranged to avoid an obstacle. ### Claim 2 (depends on 1) The movable container of claim 1, wherein the outer shell is made of a first material and the case is made of a second material, and a hardness of the second material is less than a hardness of the first material. ### Claim 3 (depends on 1) The movable container of claim 1, wherein the case includes an inner part and an outer part, the inner part is attached to the second part of the surface and the handle tube via the attachment mechanism, and outer part is attached to the first part of the surface. ### Claim 4 (depends on 1) The movable container of claim 1, further comprising: a detachable power supply device, covered by the case and fixed by an elastic band. ### Claim 5 (depends on 4) The movable container of claim 4, further comprising: a plurality of motors arranged to provide a momentum to the movable container; and a power distribution board coupled to the plurality of motors and the detachable power supply device; wherein a wire between the power distribution board and the detachable power supply device go through an opening. ### Claim 6 (depends on 5) The movable container of claim 5, wherein the opening is located on the second part of the surface. ### Claim 7 (depends on 5) The movable container of claim 5, wherein the opening is cut through between the second part of the surface and the case. ### Claim 8 (depends on 7) The movable container of claim 7, wherein the opening is located on the handle tube. ### Claim 9 (depends on 4) The movable container of claim 4, further comprising: a power distribution board coupled to the sensing device and the detachable power supply device; wherein a wire between the power distribution board and the detachable power supply device go through an opening. ### Claim 10 (depends on 1) The movable container of claim 1, wherein the image sensor is located on another surface of the movable container or on a top of the handle. ### Claim 11 (depends on 1) The movable container of claim 1, further comprising: a processing circuit, electrically connected to the sensing device, wherein the processing circuit is arranged to process the recognition feature; and an electronic device, covered by the case and fixed by an elastic band, and electrically connected to the detachable power supply device and the sensing device, wherein the electronic device is arranged to provide an additional computing power. ### Claim 12 (depends on 1) The movable container of claim 1, wherein the handle is a single rod handle, and the single rod handle separates the second part of the surface. ### Claim 13 (depends on 1) The movable container of claim 1, the attachment mechanism comprises an adhesive.
