DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(11) The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the instant disclosure. Other objectives and advantages related to the instant disclosure will be illustrated in the subsequent descriptions and appended drawings.

(12) FIGS. 1, 2 and 3 show a robot with a support in accordance with an embodiment of the instant disclosure. The robot 1 comprises a movable base 10 and a torso 20. The movable base 10 comprises a plurality of wheels 11 and 11 such that the robot 1 could be movable. The torso 20 comprises a lower portion 21 and an upper portion 22. The lower portion 21 is fixedly mounted to the movable base 10. The upper portion 22 is substantially installed to the lower portion 21. Such combination of the lower portion 21 and the second portion causes the torso 20 to be telescopic. Further, the robot 1 comprises a liner actuator 30 (see FIG. 4). The linear actuator 30 will drive the upper portion 22 to move relative to the lower portion 21 and along an axial direction of the torso 20. That is, the torso 20 could be variable in length when the upper portion 22 and the lower portion 21 are moved axially relative to each other in a telescopic manner by the linear actuator 30.

(13) The robot 1 further comprises a support 23. The support 23 is substantially connected to the upper portion 22 of the torso 20. That is, the support 23 will move upwardly and downwardly when the upper portion 22 moves relative to the lower portion 21. Moreover, the support 23 comprises a joint 231 such that the support 23 could be foldable.

(14) In addition, the robot 1 further comprises a robotic arm 27. The robotic arm 27 comprises an upper unit 271 and a lower unit 272. One end of the upper unit 271 is substantially connected to one side of the upper portion 22 of the torso 20 and the other end of the upper unit 271 is connected to the lower unit 272. The upper unit 271 has at least one degree of freedom with respect to the upper portion 22 of the torso 20 and the lower unit 272 has at least one degree of freedom with respect to the upper unit 271. Moreover, since the robotic arm 27 is connected to the upper portion 22 of the torso 20, the robotic arm 27 will move upwardly and downwardly when the upper portion 22 moves relative to the lower portion 21.

(15) FIG. 4 is a schematic view showing a linear actuator arranged in a robot with a support in accordance with an embodiment of the instant disclosure. The linear actuator 30 is arranged within the robot 1 and comprises a motor 31, a gear reducer 32, a screw rod 33 and a lifting platform 34. The motor 31 and the gear reducer 32 are substantially arranged within the movable base 10 and the motor 31 is connected to the gear reducer 32. The screw rod 33 is connected to the gear reducer 32 and axially extends into the interior of the torso 20. More precisely, the screw rod substantially extends along the longitudinal axis of the torso 20. The lifting platform 34 is screwed at the screw rod 33 and fixedly connected to the upper portion 22. Further, referring to FIG. 4, the support 23 is connected to the lifting platform 34.

(16) When the motor 31 is started, the gear reducer 32 will drive the screw rod 33 to rotate. Once the screw rod 33 rotates, the lifting platform 34 will move along the screw rod 33. Such linear motion of the lifting platform 34 will drive the upper portion 22 and the support 23 to move upwardly or downwardly relative to the lower portion 21. That is, when the liner actuator 30 is actuated, the upper portion 22 is axially moved relative to the lower portion 21 in a telescopic manner and thus the length of the torso 20 is varied. Meanwhile, the support 23 will be moved along with the movement of the second portion 21.

(17) FIGS. 5A-5D show that a robot with a support in accordance with an embodiment of the instant disclosure moves/lifts an article.

(18) Referring to FIG. 5A, when the robot 1 will move and/or lift an article, such as a chair 9, the robot 1 will move close to the chair 9 by the movable base 10. As shown in FIG. 5A, since the robot 1 does not lift the chair 9 yet, the support 23 could be foldable so as to be close to the front face of the torso 20.

(19) Referring to FIG. 5B, when the robot 1 moves close to the chair 9, the support 23 could be unfolded and against the underneath of the chair surface of the chair 9.

(20) Referring to FIG. 5C, the robot 1 further moves the robotic arm 27 so as to support the chair back of the chair 9. In such a manner, the chair 9 is tightly held by the support 23 and the robotic arm 27 of the robot 1.

(21) Referring to FIG. 5D, after the chair 9 is tightly held by the support 23 and the robotic arm 27 of the robot 1, the linear actuator 30 is actuated to drive the upper portion 22 to upwardly move relative to the lower portion 21. Meanwhile, the support 23 and the robotic arm 27 move up accordingly. Due to the upward movement of the support 23 and the robotic arm 27, the chair 9 is lifted up by the support 23 and the robotic arm 27 of the robot 1. After the chair 9 is lifted up by the support 23 and the robotic 27 of the robot 1, the robot 1 can further move the chair 9 to a desired place.

(22) In addition, the robot 1 may further comprise an inertial measurement unit (IMU) sensor (not shown) for measuring the robot's specific force and angular rate during the handling process, or/and a sensor (not shown) for monitoring electrical characteristic of the support 23, or/and an optical sensor (not shown).

(23) FIGS. 6, 7 and 8 show a robot with a support in accordance with another embodiment of the instant disclosure. The robot 1 comprises a movable base 10 and a torso 20. The movable base 10 comprises a plurality of wheels 11 and 11 such that the robot 1 could be movable. The torso 20 comprises a lower portion 21 and an upper portion 22. The lower portion 21 is fixedly mounted to the movable base 10. The upper portion 22 is substantially installed to the lower portion 21. Such combination of the lower portion 21 and the second portion causes the torso 20 to be telescopic. Further, the robot 1 comprises a liner actuator 30 (see FIG. 4). The linear actuator 30 will drive the upper portion 22 to move relative to the lower portion 21 and along an axial direction of the torso 20. That is, the torso 20 could be variable in length when the upper portion 22 and the lower portion 21 are moved axially relative to each other in a telescopic manner by the linear actuator 30.

(24) The robot 1 further comprises an arm-like support 25. The support 25 is substantially connected to one side of the upper portion 22 of the torso 20. Thus, the support 25 will move upwardly and downwardly when the upper portion 22 moves relative to the lower portion 21. Further, the support 25 can slightly move relative to the upper portion 22.

(25) In addition, the robot 1 further comprises a robotic arm 27. The robotic arm 27 comprises an upper unit 271 and a lower unit 272. One end of the upper unit 271 is substantially connected to the other side of the upper portion 22 of the torso 20 and the other end of the upper unit 271 is connected to the lower unit 272. The upper unit 271 has at least one degree of freedom with respect to the upper portion 22 of the torso 20 and the lower unit 272 has at least one degree of freedom with respect to the upper unit 271. Moreover, since the robotic arm 27 is connected to the upper portion 22 of the torso 20, the robotic arm 27 will move upwardly and downwardly when the upper portion 22 moves relative to the lower portion 21.

(26) FIG. 9 is a schematic view showing a linear actuator arranged in a robot with a support in accordance with another embodiment of the instant disclosure. The liner actuator 30 is arranged within the robot 1 and comprises a motor 31, a gear reducer 32, a screw rod 33 and a lifting platform 34. The motor 31 and the gear reducer 32 are substantially arranged within the movable base 10 and the motor 31 is connected to the gear reducer 32. The screw rod 33 is connected to the gear reducer 32 and axially extends into the interior of the torso 20. More precisely, the screw rod substantially extends along the longitudinal axis of the torso 20. The lifting platform 34 is screwed at the screw rod 33 and fixedly connected to the upper portion 22.

(27) When the motor 31 is started, the gear reducer 32 will drive the screw rod 33 to rotate. Once the screw rod 33 rotates, the lifting platform 34 will move along the screw rod 33. Such linear motion of the lifting platform 34 will drive the upper portion 22 and the support 25 to move upwardly or downwardly relative to the lower portion 21. That is, when the liner actuator 30 is actuated, the upper portion 22 is axially moved relative to the lower portion 21 in a telescopic manner and thus the length of the torso 20 is varied. Meanwhile, the support 25 will be moved along with the movement of the second portion 21.

(28) FIGS. 10A-10D show that a robot with a support in accordance with another embodiment of the instant disclosure moves/lifts an article.

(29) Referring to FIG. 10A, when the robot 1 will move and/or lift an article, such as a chair 9, the robot 1 will move close to the chair 9 by the movable base 10.

(30) Referring to FIG. 10B, when the robot 1 moves close to the chair 9, the support 25 could be against the underneath of the chair surface of the chair 9.

(31) Referring to FIG. 10C, the robot 1 further moves the robotic arm 27 so as to support the chair back of the chair 9. In such a manner, the chair 9 is tightly held by the support 25 and the robotic arm 27 of the robot 1.

(32) Referring to FIG. 10D, after the chair 9 is tightly held by the support 25 and the robotic arm 27 of the robot 1, the linear actuator 30 is actuated to drive the upper portion 22 to upwardly move relative to the lower portion 21. Meanwhile, the support 25 and the robotic arm 27 move up accordingly. Due to the upward movement of the support 25 and the robotic arm 27, the chair 9 is lifted up by the support 25 and the robotic arm 27 of the robot 1. After the chair 9 is lifted up by the support 25 and the robotic 27 of the robot 1, the robot 1 can further move the chair 9 to a desired place.

(33) In addition, the robot 1 may further comprise an inertial measurement unit (IMU) sensor (not shown) for measuring the robot's specific force and angular rate during the handling process, or/and a sensor (not shown) for monitoring electrical characteristic of the support 23, or/and an optical sensor (not shown).

(34) However, the above embodiments merely describe the principle and effects of the present disclosure, instead of being used to limit the present disclosure. Therefore, persons skilled in the art can make modifications and variations to the above embodiments without departing from the spirit of the present disclosure. The scope of the present disclosure should be defined by the appended claims.
