Currently all seafood processing in the U.S. is done completely by hand by human workers. Often seafood processing plants don't have enough workers to handle the influx of fish so they end up sending this extra seafood overseas to be processed before buying it back and selling it to U.S. consumers. This is a very inefficient and costly problem which can be solved by automation and robotics. Working with seafood plants in Alaska and Massachusetts we have indentified a need for robotic systems that can pick various types of seafood off a conveyor belt and sort them based on type and weight while working in close proximity to human workers performing similar tasks.
I am currently leading the motion planning and high level behavior/integration development of this project. Through our testing with humans, we observed that the robot would cause nearby humans to feel uneasy when performing motions that were not human-like even though these motions were the most efficient from the robot's perspective. I have worked to adjust our motion planning algorithms to balance the most efficient path with human safety and comfort to ensure that the work of the nearby human workers is not negatively impacted by the robot. Additionally, we have used the developed motion planning algorithms to successfully pickup fish and sort them into piles based on their weight. My responsibilties included integrating and testing various grippers to identify which is most successful in firmly grasping the fish without damaging them. The types of grippers have varied from having soft and hard fingers to having electrical and pneumatic control mechanisms. I have participated in demos of this project at a conference in Las Vegas and at seafood processing plants in Massachusetts to multiple high-profile pepole including the Governor of Massachusetts and the President of Northeastern University.
