Abstract
A controller is provided for manipulating objects by a robot arm having a gripper. The controller includes a large language model (LLM) planner configured to acquire the states and the task description and generate an action sequence command that operates the robot arm with the gripper based on the task description, the current observations, historical information including historical actions and historical observations from previous steps. The controller includes a robot interface configured to generate and transmit commands to operate the robot arm in response to the action sequence from the LLM planner and an LLM evaluator configured to acquire the states, the current observations, analyze the historical information including historical actions and historical observations from previous steps, evaluate missing information required to complete the task, evaluate new information acquired by the sensors, estimate a task-execution status after the robot arm operated the generated action sequence, and output updated information to the LLM planner.
