V-GUIDE™ BENEFITS

Fast

V-Guide™ is the fastest robot guidance system available, providing 6 degrees of freedom offsets in milliseconds.

Dependable

V-Guide™ is not affected by ambient factory lighting and requires no external lights, reducing faults and downtime.

Flexible

It easily accommodates style additions and model changes, requiring no additional sensors.

Robust

V-Guide™ is built to withstand punishing factory conditions and keep on working.

Versatile

It can dependably calculate the largest part-to-part shifts and rotations of any guidance system available.

Simple

Installation, operation, adjustments, and maintenance are quick, easy and economical.

APPLICATIONS

Racking/DeRacking

Seam Sealing

Precision Pick & Transfer

HOW IT WORKS

Not all vision guidance systems for robots work the same way. Ours can do more and perform better because of our advanced sensor and software technology. The result is much shorter cycle times, greater dependability, more versatility and ease of use.

Our R&D labs developed proprietary technology using volumetric VSx sensors and advanced software to give robots vision. This vision provides offsets for parts in true 3D, 6 degrees of freedom (DoF).

This volumetric data is used to compare the object’s nominal pose and calculate its offset. It can then tell a robot precisely where an object is located so that it can make necessary adjustments when moving to grasp the part. Liberty Reach was the pioneer in using 3D volumetric sensors to guide robots in this way.

QUICK CASE STUDY

Reducing Door Seam Sealing Cycle Time

Challenge – an auto maker needed to significantly reduce the time it took to complete its door seam sealing process but was hitting a dead end with its existing systems. Robot-mounted vision guidance systems typically require 3 or more measurements to infer a part offset in 6 degrees of freedom. This kind of feature-based technology has many disadvantages and issues that cause faulting, inaccuracies and more.

Solution – Liberty Reach offered a better, more effective way using V-Guide™. With V-Guide™, volumetric sensors use one image to map a part in 3D, and using LR proprietary algorithms, provide an offset– all in less than a second. It’s faster, more reliable and more versatile.

Outcome – 6 V-Guide™ systems we installed to guide robots performing seam sealing of hang-on parts: one for each of four doors, the hood and lift gate. V-Guide™ requires 2 fewer images and 2 fewer robot movements, saving the auto maker 8 seconds in the door sealing process alone. With cycle time savings of this magnitude, V-Guide™ pays for itself in a matter of days.
