Simbe has launched Tally 4.0, the fourth generation of its autonomous shelf-scanning robot, featuring up to 12 hours of runtime and enhanced computer vision capabilities powered by NVIDIA’s AI infrastructure. The San Francisco-based company announced the release Jan. 12, with units available to customers starting mid-2026.
The new platform builds on a decade of deployments across grocery, club, farm supply and home improvement retailers in 10 countries. Tally 4.0 retains the same shopper-friendly form factor as previous versions while introducing hardware and software upgrades designed to capture more shelf data with greater accuracy and speed.
“Tally 4.0 represents what 10 years of collaboration with the world’s best retailers makes possible,” said Jeff Gee, Simbe co-founder and chief design officer. “While the robot is faster, sharper and more capable, its design has stood the test of time. Tally 4.0 stays true to the principle that has guided us since day one: Technology should serve people.”
Extended coverage, real-time processing
The extended 12-hour runtime enables full-day and overnight shelf scanning with shorter charging cycles. Simbe said the upgrade supports retailers seeking continuous coverage of inventory conditions, pricing accuracy and planogram compliance.
The robot’s new ultra-high-resolution imaging system improves detection of small labels, recessed SKUs and complex fixtures. Expanded coverage now includes bunkers alongside existing capabilities for top stock, upper steel, coolers, freezers and hooks. Dual fisheye cameras provide 360-degree panoramic views for digital twin-like store walk-throughs.
Edge computing upgrades leverage NVIDIA CUDA, TensorRT and DOCA Argus to accelerate onboard processing. The architecture reduces latency between data capture and insight delivery while supporting real-time navigation alongside depth cameras powered by RealSense.
“Running physical AI at the edge is critical to making robots and humans work better together in retail environments,” said Azita Martin, VP and general manager of AI for retail and CPG at NVIDIA.
“Simbe’s Tally 4.0 robots, supported by NVIDIA’s full-stack AI infrastructure platform, demonstrates the power of real-time AI, enabling retailers to turn shelf data into immediate, high-impact decisions at the store level, as well as massive operational decisions at enterprise scale.”
Data layer for physical stores
Simbe positions Tally 4.0 as the foundation for connecting digital decision-making with physical store execution. The platform feeds data into use cases including on-shelf availability tracking, price and promotion verification, item location precision, planogram compliance, demand forecasting, replenishment automation and omnichannel fulfillment.
“The future of retail depends on closing the gap between digital decision-making and physical execution,” said Brad Bogolea, co-founder and CEO of Simbe. “With Tally 4, we’re delivering the next foundation of shelf-level data infrastructure that connects the two, giving retailers a trusted source of ground truth to power AI-driven operations at enterprise scale.”
The company’s Store Intelligence platform combines Tally’s autonomous scanning with complementary tools including Tally RFID for apparel and specialty tracking, Tally Spot for stationary capture points, and mobile and analytics applications for store teams and suppliers.
Momentum following 10th anniversary
The Tally 4.0 launch follows Simbe’s celebration of the robot’s 10th anniversary in late 2025. The company also established a Client Advisory Board bringing together leaders from major global retailers to guide store intelligence development.
Recent deployments include Harmons Grocery, which expanded Tally usage following pilot programs. Simbe said it’s seeing continued adoption across multiple retail verticals and growing international investment from retailers seeking real-time shelf visibility.
The platform now operates across nearly a dozen retail sectors beyond traditional grocery, including supercenters, wholesale clubs, farm supply chains, home improvement stores and alcoholic beverage retailers.
