Ambi Robotics, a leading provider of AI-powered robotics for commercial operations, today announced that it has been named a 2026 RBR50 Innovation Award winner for AmbiStack, an advanced AI-powered multi-purpose robotic system autonomously stacking packages onto pallets or into containers.
For over a decade, the RBR50 Innovation Awards have recognized the most innovative and influential organizations in the robotics industry. AmbiStack was selected for its industry advancement in physical AI: the robot can stack uniform and non-uniform packages without prior knowledge of their size, position, or appearance using cameras, machine vision, and AI to identify items and strategically stack them onto pallets or into walled containers.
“AmbiStack’s recognition in the RBR50 Innovation Awards speaks to the increasing demand for automation that can perform reliably in complex, real-world environments,” said Jim Liefer, CEO of Ambi Robotics. “For our customers, that translates directly into greater efficiency and more predictable operating costs, bringing consistency and scalability to an industry that greatly needs it.”
In 2025, COO and Co-Founder Stephen McKinley led the first commercial implementation of AmbiStack at one of the largest shipping and logistics company’s warehouse sites. AmbiStack is now deployed in high-volume logistics hubs across the nation, helping companies move packages faster, denser and with fewer labor constraints. Since its initial deployment, AmbiStack has improved customer throughput by 5x and stacks mixed cases onto pallets or into walled containers with maximum density – far beyond the industry average of 68% stack density.
“The commercial deployment of AmbiStack represents a major milestone for our technology and proves its reliability at scale,” said McKinley. “This award win is further validation of the work that has gone into bringing physical AI into the warehouse as a practical automation solution.”
This is Ambi Robotics’ third RBR50 Award: AmbiOS was recognized in the Technology and Services category in 2021, and AmbiSort B-Series was recognized in the Technology, Product, and Services category in 2024. The full list of 2026 winners can be viewed here.
