CHARTRES-DE-BRETAGNE, France, Aug. 17, 2026 — Alstef Mobile Robotics, the mobile robotics subsidiary of Alstef Group, is building a 13,000 sqm production facility in Rennes Métropole dedicated to manufacturing its new generation of autonomous intelligent vehicles (AIV). The site will support a ramp-up to 300 automated guided vehicles a year by 2027. Works are due to begin in August 2026, in an investment of around EUR 20 million.
The vehicles being industrialized at the site come out of the company's "Road to 2026" R&D programme. Alstef introduced the AIV platform earlier in 2026, built around a perception dome — a continuously updated awareness zone that combines on-board cameras with AI models to classify objects in the vehicle's environment, distinguishing pedestrians from manual carts, pallets and fixed infrastructure. The perception system is offered in a front-and-rear configuration and a full 360-degree version.
Consolidating two sites
The facility occupies 3.2 hectares of the former Stellantis site at the La Janais Industrial Excellence Hub, an area of Rennes Métropole undergoing reindustrialization. It brings together activities currently split between the company's Mordelles and Pacé locations, and comprises 11,000 sqm of workshop space and 2,000 sqm of offices. Production workshops are scheduled for delivery in August 2027 and offices in September 2027. Alstef Mobile Robotics will be tenant of the building under a twelve-year firm lease. Alstef Group is delivering the project with construction company Legendre, with Linovim acting as advisor.
Consolidation is intended to improve operational efficiency and logistics coordination between departments as production volumes rise. “This is a major milestone for our company: tangible recognition of the work accomplished, and above all a key driver to keep growing, further industrialize our operations and prepare for the future under the best possible conditions,” said Olivier Imbert, managing director of Alstef Mobile Robotics.
Building design
The design targets PassivHaus certification and anticipates future RE2020 requirements, making extensive use of structural timber in a biosourced design with reduced operational energy consumption. Workspaces have been specified around ergonomics and quality of life at work.
Alstef Mobile Robotics designs and manufactures AGV and AMR systems for warehousing and airport operations, including ULD and container handling vehicles and air freight pallet AGVs for air cargo terminals.
