System and method for transfer of loads from mobile robots

A system comprising:

• a transportable conveyor platform configured to receive a load thereon, the transportable conveyor platform comprising a frame, at least one roller supported by the frame, and a drive mechanism configured to drive the at least one roller to rotate about an axis;
• a mobile robot device comprising a robot battery, the mobile robot device being configured to receive the transportable conveyor platform and transport the transportable conveyor platform along a surface using electrical power provided by the robot battery;
• and
• a lift mechanism comprising first and second lift columns and a lift platform, the lift platform being configured to engage the transportable conveyor platform for lifting the transportable conveyor platform from the mobile robot using a lift mechanism power source separate from the robot battery,
• wherein the drive mechanism is configured to drive the at least one roller using electrical power from a power source that is separate from the robot battery, and
• wherein the power source is the lift mechanism power source, and wherein the transportable conveyor platform includes at least one electrical contact positioned to electrically couple the drive mechanism to the lift mechanism power source when the transportable conveyor platform is disposed on the lift mechanism.

A method comprising:

• placing a transportable conveyor platform on a mobile robot device, the transportable conveyor platform comprising a frame supporting at least one roller;
• operating the mobile robot device to transport the transportable conveyor platform to a lift mechanism using power provided from a robot battery of the mobile robot device;
• lifting the transportable conveyor platform from the mobile device to a desired height using the lift mechanism, the lift mechanism lifting the transportable conveyor platform using power from a lift mechanism power source separate from the robot battery;
• and
• rolling a load to or from the transportable conveyor platform
• wherein the at least one roller comprises a powered roller for rolling the load off the transportable conveyor platform, and
• wherein the powered roller is driven using electrical power from a power source separate from the robot battery.

A system comprising:

• a transportable conveyor platform configured to receive a load thereon, the transportable conveyor platform comprising a frame and at least one roller supported by the frame;
