Robotic payload transport system
A roller conveyor system configured for installation on top of a mobile robot to provide robotic transport of a payload includes: a roller conveyor, the roller conveyor comprising: a roller assembly, the roller assembly comprising a plurality of rollers, the rollers configured to move a payload, each of the rollers being configured to rotate, the roller assembly comprising a motorized roller and one or more auxiliary rollers, the motorized roller comprising a motor configured to cause the motorized roller to rotate; and a hybrid power transmission configured to drive the rollers, the hybrid power transmission coupling the motorized roller to at least one of the one or more auxiliary rollers, the hybrid power transmission using at least two power transmission methods.
1. A roller conveyor system configured for installation on top of a mobile robot to provide robotic transport of a payload, comprising:
a roller conveyor, the roller conveyor comprising:
a roller assembly, the roller assembly comprising a plurality of rollers, the rollers configured to move a payload, each of the rollers being configured to rotate, the roller assembly comprising a leading roller disposed adjacent to a secondary roller, a motorized roller disposed adjacent to the secondary roller and one or more auxiliary rollers, the motorized roller comprising a motor configured to cause the motorized roller to rotate, wherein the secondary roller, the motorized roller and the one or more auxiliary rollers each have a first length that is longer than a second length of the leading roller so that the roller assembly fits within a circular profile defined by the second length of the leading roller; and
a hybrid power transmission configured to drive the rollers, the hybrid power transmission coupling the motorized roller to at least one of the one or more auxiliary rollers, the hybrid power transmission using at least two power transmission methods.
2. The roller conveyor system of claim 1 , wherein the hybrid power transmission comprises a hybrid belt drive.
3. The roller conveyor system of claim 1 , wherein moving the payload comprises moving the payload toward a front side of the roller conveyor.
4. The roller conveyor system of claim 1 , wherein moving the payload comprises moving the payload toward a back side of the roller conveyor.
5. The roller conveyor system of claim 1 , further comprising a riser assembly configured to support the roller conveyor.
6. The roller conveyor system of claim 5 , wherein the riser assembly comprises an actuator usable to adjust a height of the roller conveyor above the mobile robot.
7. The roller conveyor system of claim 1 , wherein the rollers are configured to move the payload toward a front side of the roller conveyor.
8. The roller conveyor system of claim 1 , wherein the motorized roller is physically coupled to one or more auxiliary rollers by one or more poly-V belts.
9. The roller conveyor system of claim 1 , wherein the auxiliary rollers are adjacent to and behind the motorized roller.
10. The roller conveyor system of claim 1 , wherein all rollers rotate in a same direction.
11. The roller conveyor system of claim 1 , wherein the leading roller is positioned nearest to a front side of the roller conveyor.
12. The roller conveyor system of claim 1 , wherein the motorized roller is positioned adjacent to and immediately behind the secondary roller.
13. The roller conveyor system of claim 1 , wherein the motorized roller is coupled, either directly or indirectly, to the secondary roller.
14. The roller conveyor system of claim 1 , wherein the motorized roller is physically coupled to the secondary roller.
15. The roller conveyor system of claim 1 , wherein the motorized roller is physically coupled to the secondary roller by a poly-V belt.
16. The roller conveyor system of claim 1 , wherein the secondary roller is coupled, either directly or indirectly, to the leading roller.
17. The roller conveyor system of claim 1 , wherein the secondary roller is physically coupled to the leading roller.
18. The roller conveyor system of claim 1 , wherein the secondary roller is physically coupled to the leading roller by an O-ring belt.
19. The roller conveyor system of claim 1 , wherein the roller conveyor further comprises a backstop operably connected to the roller assembly at a back side of the conveyor.
