Retrocausal, a provider of visual mistake-proofing software for manufacturing assembly, has released RetroActivity software, which offers advancements in quality control for manual assembly processes in discrete manufacturing.
Powered by artificial intelligence (AI), Retroactivity is designed to improve overall quality and efficiency by identifying errors or missed steps to assembly workers through verbal prompts and visual cues. The company projects improvements of 10% in first-time yields and reductions of 60% in manual assembly related quality issues at a typical factory.
Retrocausal was originally developed to help surgical residents and nurses train for complex medical procedures in collaboration with CAE Healthcare and NASA Johnson Space Center. But the company soon identified an even bigger need in U.S. manufacturing for its technology to provide continuous quality monitoring and training for workers, alongside analytics for industrial engineers and managers. Retrocausal recently partnered with Siemens Digital Industries Software Co. and is working with some of the largest players in mass-customized manufacturing to improve manual assembly-related quality issues in discrete manufacturing.
Dr. Zeeshan Zia, CEO and a co-founder of Retrocausal, said, "There is a popular belief that robotics will replace manufacturing jobs. However, when compared to human labor, there are many instances of industrial robots being slower, taking up more space and not being as adaptable as humans. That is why many major manufacturers have recently been turning back to human workers, especially for products that require various degrees of customization for specific usage. But with experienced workers retiring at the highest rates since the industrial revolution, it can be difficult to train new assembly workers and ensure consistent quality control in the assembly process."
"In the last 10 years, temporary employment in U.S. manufacturing has more than tripled," said a company spokesperson. "Temporary workers are often less knowledgeable than the rest of the staff, leading to higher training requirements as well as quality and productivity challenges. Another trend in manufacturing is an increasing customer demand for customizations. All these factors are leading to increased quality woes for discrete manufacturers, where Cost of Poor Quality (CoPQ) is already at 20% of total sales."
How RetroActivity Works
RetroActivity is a computer vision technology, powered by AI, that understands complex human activities, as well as the specific details of the parts being assembled. RetroActivity comes loaded onto a small computer (6" x 6" x 6" box) with a Bluetooth camera and an adjustable mount. Alternately, the project engineer can elect to install the RetroActivity software on an existing hardware system or run it on multiple assembly lines through the cloud.
The key points of setting up the system are as follows:
- The industrial engineer records a series of video demonstrations of an expert assembler with each version of the finished product to digitize the bill of process.
- The video demonstrations are used for the AI software to learn a computational step-by-step model of the activity, which is ready to deploy within a few hours.
- Then the system is ready to monitor a less experienced worker who is assembling a complex truck panel, a computer system or any other complex machine.
- RetroActivity software provides specific feedback in real time to ensure that the assembly worker is following the correct procedure for the assembly of a specific version of a product.
- In addition, the analytics dashboard is used by lean engineers to perform root cause analysis and continually improve processes.
Traditionally, manufacturers have focused on two types of tools to improve quality on their lines: (1) machine vision systems for part defect detection, and (2) physical mistake-proofing mechanisms that make it hard to make certain kinds of mistakes.
Dr. Zia said, "Machine vision systems often focus on QC stations, which are generally found at the end of the assembly line. In practice, by the time a product reaches the QC station it is already too late. Workers have made their mistakes, and the product either needs to go through another line for disassembly and fixing or be discarded, which are both costly options."
RetroActivity is available for delivery and can be purchased on a monthly subscription basis. In addition, the Retrocausal solutions engineers are available to help integrate the system into existing manufacturing execution systems.
