Assistive robot systems for container tilting

1. An assistive robot system comprising:

a lifting mechanism;

a movable arm assembly coupled to the lifting mechanism;

a container tilting arm assembly;

a processing device communicatively coupled to the lifting mechanism and the movable arm assembly; and

a non-transitory, processor-readable storage medium in communication with the processing device, the non-transitory, processor-readable storage medium comprising one or more programming instructions that, when executed, cause the processing device to:

transmit a command to the lifting mechanism to cause the lifting mechanism to move the movable arm assembly such that the container tilting arm assembly makes contact with a container gripped by the movable arm assembly, and

transmit one or more signals to the movable arm assembly to cause the movable arm assembly to extend in a system longitudinal direction such that the container gripped by the movable arm assembly is pivoted against the container tilting arm assembly to tilt the container within the movable arm assembly.

2. The assistive robot system of claim 1 , wherein:

the movable arm assembly comprises a pair of movable arms;

each movable arm of the pair of movable arms comprises a longitudinal telescoping assembly and a lateral telescoping assembly;

the longitudinal telescoping assembly comprises a plurality of longitudinal telescoping segments configured to extend and retract in the system longitudinal direction; and

the lateral telescoping assembly comprises a plurality of lateral telescoping segments configured to extend and retract in the system lateral direction.

3. The assistive robot system of claim 1 , wherein the container tilting arm assembly is a pair of arms defining a gap.

4. The assistive robot system of claim 3 , wherein an elongated member is connected to the pair of arms in a direction traverse to the pair of arms such that the elongated member contacts the container within a zone of contact of the container.

5. The assistive robot system of claim 3 , wherein each arm of the pair of arms further includes a member extending in a direction traverse to the pair of arms and into the gap such that each member contacts the container within a zone of contact of the container.

6. The assistive robot system of claim 1 , wherein the container tilting arm assembly is adjustable in a system vertical direction such that a height at which the container is tipped is adjustable.

7. The assistive robot system of claim 1 , further comprising a base having an upper surface, wherein the container tilting arm assembly is stored in one or more recesses in the upper surface of the base.

8. An assistive robot system comprising:

a lifting mechanism;

a movable arm assembly coupled to the lifting mechanism;

a container tilting arm assembly;

a sensor device that senses an area surrounding the assistive robot system; and

a processing device communicatively coupled to the sensor device, the lifting mechanism, and the movable arm assembly,

wherein:

data is transmitted from the sensor device to the processing device,

the processing device processes the data and determines one or more movement commands, and

the processing device transmits one or more signals corresponding to the one or more movement commands to:

cause the lifting mechanism and the movable arm assembly to move and grip a container,

cause the lifting mechanism to move the movable arm assembly such that the container tilting arm assembly contacts the container gripped by the movable arm assembly at a zone of contact, and

cause the movable arm assembly to extend in a system longitudinal direction such that the container within the movable arm assembly is pivoted against the container tilting arm assembly to tilt the container within the movable arm assembly.

9. The assistive robot system of claim 8 , wherein the sensor device is configured to identify whether a second container is stored in the container tilting arm assembly.

10. The assistive robot system of claim 8 , wherein the sensor device is configured to identify whether a plurality of articles within the container have been emptied from the container during the tilting.

11. The assistive robot system of claim 8 , wherein the sensor device is configured to identify whether the container tilting arm assembly is in a proper position to make contact with the container.

12. The assistive robot system of claim 11 , wherein the processing device transmits one or more signals corresponding to the one or more movement commands to:

cause the lifting mechanism and the movable arm assembly to move and grip the container tilting arm assembly so to place the container tilting arm assembly in the proper position for tilting the container.

13. The assistive robot system of claim 8 , wherein the container tilting arm assembly is adjustable in a system vertical direction such that a height at which the container is tipped is adjustable.

14. The assistive robot system of claim 8 , wherein the container tilting arm assembly is a pair of arms defining a gap.

15. The assistive robot system of claim 14 , wherein:

each arm of the pair of arms is foldable between a first position and a second position,

the first position is where the pair of arms extend in the system longitudinal direction, and

the second position is a stowed position where the pair of arms extend in a system vertical direction such that the pair of arms are folded when not in use.

16. The assistive robot system of claim 14 , wherein an elongated member is connected to the pair of arms in a direction traverse to the pair of arms such that the elongated member contacts the container within the zone of contact of the container.

17. The assistive robot system of claim 14 , wherein each arm of the pair of arms further includes a member extending in a direction traverse to the pair of arms and into the gap such that each member contacts the container within the zone of contact of the container.

18. The assistive robot system of claim 8 , wherein:

the movable arm assembly comprises a pair of movable arms;

each movable arm of the pair of movable arms comprises a longitudinal telescoping assembly and a lateral telescoping assembly;

the longitudinal telescoping assembly comprises a plurality of longitudinal telescoping segments configured to extend and retract in the system longitudinal direction; and

the lateral telescoping assembly comprises a plurality of lateral telescoping segments configured to extend and retract in the system lateral direction.
