Robotics & Automation

Robots and automated processes have transformed how global companies make and distribute products. For students interested in robotics, LGO offers coursework and research along a sophisticated automation toolkit, both in the classroom and in robotics internships. Multiple departments at MIT are researching the many ways that robotics and automation can solve problems. Aeronautics and Astronautics, Mechanical Engineering, and Electrical Engineering departments all offer robotics classes. MIT’s cross-disciplinary institutes like CSAIL and the Media Lab also contribute to groundbreaking research on the topic. Several LGO partner companies have leveraged LGO internships in robotics to develop automation solutions.

Deep Learning Image Augmentation to Improve Performance of Automated Visual Inspection (AVI) Systems

Deep learning has potential to increase the flexibility and robustness of current automated visual inspection systems but requires a lot of training data to achieve optimal performance. In drug product manufacturing, the deliberate creation of defective units for training is complex and costly. Amgen and AJ sought solutions to reduce the cost of training images for deep learning visual inspection systems.

The images used for training the deep learning image generation tools were captured by a camera station in a tech development laboratory.

Approach: AJ developed two sophisticated deep learning tools to generate synthetic images for training, using both inpainting with partial convolution and generative adversarial networks (GANs). These tools were able to generate a much larger number of images based on a smaller sample of training images than were previously needed.

Impact: The synthetic images resulting from AJ’s innovative approach drove a dramatic improvement in the overall accuracy of the deep learning classifiers, which translates into smaller false eject and accept rates for the visual inspection system. AJ received the 2021 LGO Best Thesis award for his new approach to generating training images, which, as one of his faculty advisors stated, will “save enough to more than justify [the] cost while providing a basis for further development and savings in the future.”

Problem: Amazon Robotics’ well-known orange robots have revolutionized the retail industry; they can be seen moving materials to and from storage in many fulfillment centers. On the floor, obstructions such as fallen products and deactivated robots can reduce overall throughput. Ankur’s project aimed to understand the cost-benefit tradeoff of entering the floor to resolve obstructions.

Approach: Ankur created a new framework to estimate the operational impact of entering the floor.  With this model, he developed proposed guidelines for when to enter the floor or not, consulting with fulfillment center staff to better understand the context. He applied an Agile Method approach to rapidly develop and pilot a software tool to deliver recommendations in the field.

Impact: During the treatment shifts on the floor, Amazon workers experienced low idle time, and about three times as many floor obstructions were resolved during non-operation by avoiding floor entries the model deemed unnecessary during operation. Ankur’s model can help standardize floor entry decisions across the Amazon fulfillment center network and improve future performance.

Evaluation of Automated Storage and Retrieval in a Distribution Center

More consistent retrieval processes provided by ASRS can significantly decrease total processing and delivery time

Problem: Facing ecommerce growth and rising customer delivery expectations, companies must adapt to meet shorter contract shipping requirements with existing infrastructures. The “Amazon effect,” resulting in increased online shopping and direct-to-consumer order fulfillment, is reverberating through the retail industry, requiring manufacturers to evaluate their existing supply chain networks to meet 1-2-day shipping from their distribution centers (DCs). Adriane evaluated speed and execution improvements at Nike using automated storage and retrieval systems (ASRS) in DCs.

Approach: Adriane first evaluated the current DC state to create a time savings simulation to quantify automation results. She researched what ASRS were available and determined what inputs changed selections most to build retrofit options. Her next step was creating a model that calculated SKU input/output costs for the ideal ASRS from throughput and inventory requirements. 

Impact: Analysis of the DC evaluated indicated the primary delay in shipping time was due to high variability in task completion time, rather than a high average completion time. Implementation of ASRS in the DC could decrease processing time in storage and retrieval by 67%, and total processing time through the DC by 37% due to ideal sequencing, diminished downstream variability, and reduced work in progress.
