Product overview

A gantry robot consists of a manipulator mounted onto an overhead system and allows movement across a horizontal plane. Gantry robots are also called linear or cartesian robots and are typically large systems built with linear guide rails that undertake pick and place actions, and they can also be used in applications such as welding. Cartesian gantries are relatively simple to program when compared to alternative motion control solutions, and in addition, they are not limited by floor space constraints. ALIO’s cartesian gantries are  characterized by large work areas and superior positioning accuracy.

Configurable Gantries

The SNH-series is a highly configurable gantry robot design based on ALIO’s proven standard stages that can be adapted according to customers’ load, throughput, precision, travel, and budget.

Customers may choose from XY travels from as little as 100mm or up to 1m plus and various powerful drive options allowing accelerations of up to 3.5G. With gantries being delivered on rigid base plates like granite, steel or aluminum frames allow superior precision with accuracy of +/- 1.5µm.

One key contributor to such high precision is our “Yaw Compliance” option — a virtual rotary axis allowing precise compensation for small angular misalignments that also may be used as an actual rotary axis for small intended angular motions.

Combining the cartesian gantry with optional degrees of freedom like z-axis, rotary axis, (Inverted) tripods or Hybrid Hexapods® or Gimbals makes this series to one of the most versatile and flexible high precision motion systems in the market.

You’ll likely find our cartesian gantries in industrial applications like laser machining or additive manufacturing / 3D printing, where an overhead motion is needed as samples can’t be moved or are extremely large.
