Intellidrives Motion Control Components - XY Gantry Robot

Philadelphia, PA, — Motion Control Components and Systems – Repeatability and accuracy are essential characteristics of any motion control system, and the objective of the design is to assure the desired trajectories can accurately follow through the working range of the system.

In traditional XY gantry designs upper gantry member (Y axis) is carried by two identical bottom axes (X1 and X2). Each X1 and X2 axes motor/screw/bearing systems are separated by finite distance orthogonal to the direction of the axes.

INTELLIGENT ACTUATORS can easily “talk over” USB 2.0, Ethenet, RS232, RS485 interfaces and come with powerful yet easy to use software packages. for system start-up and integration, like communication drivers, linkable DLL libraries, National Instruments Labview drivers and VI examples, GUI and easy-to-use DXF conversion software.

Due to the manufacturing precision of the components, such as linear guides deflections, ball screw lead errors, axes misalignment, the variation of the position errors in X1 and X2 axes controllers, XY gantries orthogonality is affected. As Y-axis with load traverses across XY plane, it also introduces X axes position errors that are Y axis position dependent.

The current approach to this design challenge is to implement 2-D position error mapping or suspend Y axis on the flexible members (flexures) and to independently control X1 and X2 axes to assure orthogonality. This approach reduces system bandwidth and provides small range of angle adjustment, usually within not more than 1 degree.

There are also many applications, where large THETA angle is an INTENTIONAL FEATURE of the system design (X-Y-THETA) to allow alignment of the work tool to the non-orthogonally located objects or to align patterns.
