LINEAR & GANTRY ROBOTS
Alpha Robotics linear robots
High-speed robots driven directly by linear motors. Use a single-axis module on its own, or combine axes into a gantry system.
OVERVIEW
Modular structure for flexible axis combinations
A linear robot is a drive module that moves in one straight line. It can be used as a single axis or combined into an X, Y, Z multi-axis gantry to suit the machine.
Every Alpha Robotics linear model uses a linear servo motor with non-contact direct drive. Maximum speed is 2.5 m/s and acceleration 2.5G, with ±1 μm repeatability when an absolute encoder is fitted. The ALS and ALXS series offer strokes up to 20 m; other series go up to 3 m.
APPLICATIONS
Typical applications
Long-stroke transfer
High-speed transfer of products, trays and jigs between distant stations
Multi-axis gantry
Linear modules combined into an X, Y, Z work envelope for the process
Pick-and-Place
High-speed picking and transfer of parts between conveyors, trays and processing positions
High-precision equipment
Chip mounters, dispensers, bonders, vision inspection machines and other equipment that needs high precision
SELECTION
Checklist before selecting a model

Multi-axis control
Controller specification, servo packs, I/O and communication with the host controller
FAQ
Common questions before you enquire
Are linear robots and gantry robots different products?
A linear robot is a single straight-motion module. A gantry robot is a multi-axis system that combines several linear modules on the X, Y and Z axes to cover a larger work area.
Do all models support strokes up to 20 m?
No. The 20 m stroke is available on the long-stroke ALS and ALXS series. Other series go up to 2 to 3 m depending on the model. Send the travel you need and we will recommend a suitable series.
Can a multi-axis system be configured for a dedicated machine layout?
Yes. Send the work area, moving load, target cycle time, control method and installation space, and we will propose a multi-axis gantry configuration for the process.
