Abstract: Traditionally, industrial robots have been used on mass production lines, where the same manufacturing operation is repeated many times. Many sectors of manufacturing such as aerospace, defense, ship building, mold and die making involve small production volumes and non-repetitive tasks. Currently, industrial robots are not used in such applications. The use of robotic assistants can significantly improve human operator productivity in small production volume manufacturing and eliminate the need for human involvement in tasks that pose risks to human health. Recent advances in human-safe industrial robots present an opportunity for creating hybrid work cells, where humans and robots can collaborate in close physical proximities. This capability enables realizing systems that utilize the complementary strengths of humans and robots. Several low-cost robots have been introduced in the market over the last few years, making them attractive in many new manufacturing applications where robot utilization is not expected to be very high. This makes the idea of hybrid cells economically viable for small volume production. This presentation will describe computational foundations for creating robotic assistants for non-repetitive manufacturing tasks. We will begin with an overview of an integrated decision making approach that brings together concepts from perception, planning, control, and learning to realize robotic assistants that can aid human workers in manufacturing. Traditional off-line robot programming approaches cannot be used on non-repetitive tasks. We will describe a new decision making approach based on the integration of real-time planning and perception for performing non-repetitive tasks using robots. There are many challenging tasks for which a simulation-based planning approach cannot be used to select the optimal process parameters. For such tasks, we will describe a new approach for robots to learn task parameters from self-exploration. Both humans and robots can make errors in a hybrid cell, hence creating contingency situations. Unless handled promptly, a contingency situation may lead to significant operational inefficiencies. We will describe a decision making approach for detecting and managing contingencies. Bin picking, assembly, and cleaning tasks will be used as illustrative examples to show how robots can be used on non-repetitive manufacturing tasks.
