- Abstract: Integrating a human-operator (HO) into a robotic system can help improve performance and reduce system complexity. This work proposes and evaluates four different strategies for human-robot collaboration in a melon identification task. Experiments were conducted to compare the performance of each strategy. Results indicated that incorporation of a HO reduces detection time by 20%, the number of operations and net operations by 40 and 67% correspondingly. Collaboration of HO and robot increases detection.
