The disclosure relates to an autonomous mobile robot (AMR) with a single modular platform comprising a monolithic chassis, top plate with standoffs for mounting material handling units, drive wheel assemblies, and a suspension unit. It enables mounting of various units like robots/cobots, tuggers, lift tables, conveyors for flexible material handling in warehouses and workspaces.

Claims

An autonomous mobile robot comprising: a monolithic chassis; a top plate with plurality of standoffs to mount at least one material handling unit; drive wheels coupled to a wheel mount; a suspension unit coupled symmetrically between the monolithic chassis and drive wheel assembly; and side plates connecting the chassis. The suspension allows vertical movement of drive wheels. Various embodiments for mounting robots, tuggers, etc.

Technical analysis

Features a rigid monolithic chassis with integrated ribs and swivel wheels, modular standoffs (short/long) for load transfer and mounting flexibility, and a spring-based suspension with linear bearings for terrain adaptability (ramps). Drive wheels centrally placed for omnidirectional-like control including turning and braking. Addresses space constraints and stability for heavy payloads while remaining compact.

Commercial impact

Enables versatile, cost-effective AMRs for logistics/warehousing by reducing need for multiple specialized platforms. Supports integration with cobots for pick-and-place, automated tugging, and rack handling, potentially lowering deployment costs and increasing adaptability in dynamic environments like e-commerce fulfillment.
