Abstract: A robot system is provided for moving and de-capping collection containers. The system can include a robotic arm having a plurality of grippers, where the plurality of grippers is configured to move a plurality of collection containers. Additionally, the system can include a decapper configured to remove a plurality of caps corresponding to the plurality of collection containers. The system further includes a computing device comprising a processor and a memory, and machine-readable instructions stored in the memory that, when executed by the processor, cause the computing device to align the plurality of grippers with the plurality of collection containers, where the plurality of grippers are connected to a distal end of the robotic arm. The instructions can further cause the computing device to cause the plurality of grippers to grip the plurality of collection containers, move the plurality of collection containers to the decapper, and de-cap the collection containers.
