  • Selectable decision threshold optimizes training time.
  • Can IGNORE clutter for object recognition.

Eyebot begins a new generation of visual inspection processors.  Eyebots are trainable inspection sensors, designed to install faster, allow more flexibility, and learn multiple product features.  Eyebots are used to inspect a variety of processes.

How does Eyebot work?  You teach Eyebot some good parts.  After learning, you tell it to RUN.  Eyebot will tell you when it sees anything you did not teach it.  You never have to turn on a PC or struggle with complicated software.

Eyebot trains in minutes to recognize key product features.  If your lighting or product position varies, then train Eyebot to accept those features under those conditions.  

How flexible is Eyebot?  Eyebot is so easy to train and retrain, that in some factories it is used for incoming, in-process, and outgoing inspection at different locations during an average week.  

Eyebot requires no PC, no operating system, no frame grabber, and no software.  It's inexpensive to install and support, and can be applied to several products or product lines.  You can use Eyebot wherever automated optical inspection was previously too complicated or too costly.  Anyone can train Eyebot.

Trainable Inspection.  Why is that better?
Training Eyebot to inspect your products can be as easy as setting up a sensor.  Here's the five steps to making Eyebot work for you:

ERASE.  Turn Eyebot knob to ERASE and press the green YES button on the right of the front panel.  Eyebot retains training for 10 years or until erased.

VIEW.  Set the size and location of the VIEW area to cover the features you want to inspect.  Turn Eyebot's knob to OPTIONS to adjust the window.  Next, turn the dial to VIEW and use the two yellow buttons to set the video threshold and feature quality.  You should be able to see the features and defects in the viewing area.  Add lighting if required.

LEARN.  Turn the knob to LEARN and press YES.  Train Eyebot by looking at good objects with the camera.  Move the objects, rotate them, or cast shadows approximately as they will appear during actual inspection.  Run good objects in front of the camera until the Score stabilizes in a high range.

TEST.  Turn knob to TEST and observe the score; the higher the score, the better the part.  Lower the Decision Threshold so that good products pass and defective products do not pass.  Train longer if necessary to increase the Score margin between good and bad parts.  This is done by repeating the LEARN step above.  Learning is cumulative, so you can build on your training until all the good parts pass with a good margin.

RUN.  Turn to RUN and get back to work.  Two optically isolated relays switch 3 amps and 60 volts.

Neural RAM Delivers Powerful and Easy Inspection!
Random Location and Orientation.  Eyebot is not just a pixel counter; its patented Neural-RAM™ technology allows it to learn up to 12 million features per second.  Your process may have variations that are acceptable.  Eyebot can learn your objects in various positions or orientations in the Non-Fixtured mode.  Train Eyebot by positioning your objects wherever they may appear during actual inspection.  Compare the costs of training Eyebot to the cost of software, courses, and costly integration of the previous generation of equipment.

Variable Lighting.  Many changes in lighting are caused by shadows and momentary changes from reflections.  Train Eyebot for a few minutes under these conditions and it will accommodate them when running.  Imagine the time and programming it takes to achieve that using traditional machine vision software.

Clutter Accommodation.  If your application requires identifying similar objects mixed with clutter, Eyebot can handle it.  How?  Teach Eyebot a part in all orientations.  IGNORE the clutter, even with motion.  It only takes a few minutes.  Random motion and clutter in a background would overwhelm most software-based inspection systems.  Eyebot learns to ignore background clutter, and identify objects you seek.

Higher Performance.  Eyebot makes up to 3600 decisions per minute, or one per video field.  That's fast.  Between 200 and 2000 products per minute, Eyebot may not even need special "part in place signals," strobe lighting, or asynchronous reset cameras.  Eyebot acts fast, and it is not slowed by Windows NT interrupts, table updates, or other overhead common in software-based systems.

Smaller Defects.  Eyebot connects to cameras or microscopes and if you can see the difference between a good and a bad part on the monitor, Eyebot can see it too.  Your optics and positioning determine the smallest defect Eyebot can detect.  The more magnification and control, the smaller the defect Eyebot can catch.

Increased Productivity.  You gain two ways with Eyebot:

  1. You do not have to endure long, tedious training classes.  Eyebot is so intuitive, you can quickly learn how to use it with a video tape and its basic, straightforward manual.
  2. Integration is a snap with Eyebot.  If an expert on SIGHTech's Eyebot and an expert on another vision system were called in, and both given the same component to inspect for a defect, who would finish first?  No contest!

Easy to Integrate.  No proprietary interfaces.  Eyebot has two optically isolated (open/close) relays built-in that switch 3 amps at 60 volts.  Use them to stop the line, power a siren, or eject the part.  You prefer RS-232?  How's ASCII text for simplicity?  Eyebot delivers it.  Eyebot easily connects to X/Y tables for careful inspection.  Since you do not have to deal with convoluted software GUI interfaces, adding a visual inspection to your process can take under anhour from start to finish.

Web Inspection.  Eyebot can inspect continuous strips of material, such as aluminum extrusions, fruit, or paper rolls.  Simply set a long, thin inspection window across the material flow on the screen and Eyebot will signal whenever it sees foreign (untrained) features.  With a decision as fast as one per video field, your product can be flying by!

Inspect Short Batch Runs.  Eyebot trains or retrains in minuts so you can use it on short production runs.  MS Eyebot stores up to eight training sessions on board and an unlimited number of sessions can be uploaded and downloaded via the RS-232 port.  If power fails, Eyebot retains its training for up to ten years.

Color, too?  Absolutely.  Spectrum Eyebot can learn and inspect colors.  It will signal when it sees colors you did not teach it.  So Eyebot can color grade produce, verify the colors of an injection molded part, and scan web print materials.  Eyebots are inspecting French Fries for mold, for example.

Spend Less, Save Time.  Eyebot hardware is inexpensive.  You realize the real savings, however, when you factor in the time saved from not having to attend classes and dealing with Byzantine user interfaces.  Eyebot goes to work faster.  It costs nearly nothing to maintain.  No OS upgrades, PC hardware driver changes, compiler rev level incompatibilities, or expensive specialty programming costs.
