Warehouse path planning using low-order Bézier curves with minimum-time optimizationBlažič, Sašo (Avtor) Klančar, Gregor (Avtor) Benko Loknar, Martina (Avtor) Škrjanc, Igor (Avtor) path planningmotion primitivesBezier curvecontinuous curvatureminimal timewarehouseIn this paper, low-order Bézier motion primitives are proposed for motion planning in corridor-constrained spaces, which is illustrated on a warehouse application. The proposed primitives are easily computed for given requirements (initial and final position, orientation and curvature). A new parametrization of the motion primitives is provided which allows an intuitive geometric interpretation. The combined path constructed from these primitives has a minimal number of turns, as third-order Bezier curves are used. At the same time, the combined path has continuous curvature. A path planning approach is proposed that finds the optimal combination of primitives that results in a minimum travel time while satisfying constraints on velocity, acceleration, and free space. To illustrate the applicability of the approach, a comparison with a typical predefined warehouse path and an existing advanced optimisation planner is provided and evaluated.20232026-07-22 09:40:52Neznano185076UDK: 681.5:519.6ISSN pri članku: 2405-8963DOI: 10.1016/j.ifacol.2023.10.578COBISS_ID: 244158467OceCobissID: 173643267sl
