Robots & Vision Show upbeatReturning to the Chicago area for the first time in 15 years, the 2001 International Robots & Vision Show and Conference was held at the Donald E. Stephens Convention Center (Rosemont, IL) last June. The atmosphere of the show, which is presented once every two years, was surprisingly optimistic, especially in the separate Vision Exhibit area. Most exhibitors admitted that business was down for the first half of this year, reflecting the national economic slowdown. However, they offered many more new products than usual and felt that sales would improve dramatically in the second half of this year.

Sponsored by the Robotic Industries Association (RIA; and the Automated Imaging Association (AIA;, both in Ann Arbor, MI, the show attracted the highest preregistrations of exhibitors and attendees in more than a decade. Nearly 200 companies exhibited the latest robots, machine-vision systems, and related factory-automated products for evaluation by more than 4500 professionals.

Donald A. Vincent, RIA executive vice president, said, "It's clear that despite the slowdown in capital-equipment buying that's taking place right now, companies are interested in robotics and machine vision and will likely resume major purchases of these technologies once the economy strengthens."

Reflecting the business downturn, the RIA reports that new orders for North American robotics companies dropped 36% in the first quarter of 2001 compared to the same period in 2000. Comments RIA's Vincent, "Based on feedback from RIA member companies, we expect to see strengthening orders in the second half of 2001." The RIA has more than 260 member companies, and it estimates that some 112,000 robots are now operating in US factories.

According to this year's AIA Machine Vision Market report, the North American machine-vision market increased 26% in 2000; the total units sold worldwide is estimated at 145,821; and worldwide sales reached $6.18 billion. Representing more than 225 member companies, AIA's executive director Jeffrey A. Burnstein said, "Machine-vision hardware and software costs are declining as performance is improving. This creates many new market opportunities for machine-vision technology in a wider range of industries than ever before." He attributes the vision industry's slow start in 2001 to slowdowns in capital-equipment expenditures, not a decline in demand for machine vision. He added, "We fully expect leading manufacturers to increase their purchases of machine vision once the global economy turns positive again. Machine vision is an essential technology for many companies and is high on the list of desired technologies for a growing number of manufacturers."

Pepperidge Farm Inc. (Norwalk, CT) received the 2001 Robots & Vision Recognition Award for its innovative use of both technologies in cookie packaging. The company has automated highly repetitive tasks by using an inspection system comprising 14 vision-guided robots. This system has boosted production capacity, improved quality, and lowered scrap losses.

In the Vision Exhibit area, exhibitors were mostly pleased with the quality and numbers of attendees, even though floor traffic varied continually from high to low levels during the three exhibit days. Not surprisingly, IEEE-1394 (FireWire) and Camera Link cameras dominated the list of new products introduced at the show, followed by various boards, software packages, and lighting devices. Another observed trend was that some companies are forming alliances to jointly share their technologies to solve user problems.

Technology TrendsSilicon Video Inc. (San Jose, CA; has demonstrated its svW1 image-warping processor chip that enables manufacturers of high-end image-acquisition and display systems to warp images dynamically in real time. The chip also can produce dynamic video effects, zoom and pan in software, and digitally correct projection on curved surfaces.

Amicas Inc. (Newton, MA; has introduced an imaging system that the company claims makes the common Picture Archiving and Communications Systems (PACS) obsolete and provides an improved method for the diagnostic imaging industry. The system comprises a personal viewer, a diagnostic workstation, a service monitor, and integration with voice recognition and electronic medical records and reports. The workstation, developed collaboratively with eFilm, is web and DICOM compatible with a JPEG2000-compliant archive. It demonstrates one-click, instantaneous, and simultaneous access to prior patient images and reports; makes the "pre-fetching" PACS technique obsolete; and integrates voice recognition technology for transcribing and accessing radiologists reports.

GenRad Inc. (Westford, MA: www. has sold an automated GR-X Station 3-D x-ray inspection system to Excelsior Manufacturing (San Jose, CA) that is expected to cut printed-circuit-board inspection test time by 1500%. The patented 3-D x-ray inspection system combines the GenRad Transmission 2-D and Digital Tomosynthesis 3-D inspection techniques into a single chassis. It inspects boards up to 18 x 22 in., offers a test rate of up to 3.0 sq in./s, and comes with two sets of fields of views to meet inspection requirements.

Three-dimensional inspection highlighted at showStereo-based three-dimensional (3-D) machine-vision systems were a highlight at the International Robots & Vision Show booth of ISRA Vision Systems (Lansing, MI). Developed for robot-guidance applications and systems capabilities for 3-D vision-guided robotic depalletizing of auto-panel body parts, the company's Location Measurement Sensor (3D- Locmes) 3-D-measurement system permits local measurement of position and objects in a 3-D space. Typical applications are tasks in automotive production such as the assembly of door panels.

In the simplest case, Locmes can be configured with one camera. With the camera mounted on the robot or movement unit, stereo systems can capture several images from different positions in the workspace.

In most cases, however, two cameras are mounted on the movement unit, so that no additional movements are necessary for measurement. Using two cameras, a measurement space of 500 x 500 x 400 mm can be evaluated with an accuracy of better than ±0.7 mm using the 3D Locmes menu-controlled software running on an industrial PC under Windows NT. This provides spatial information for the parts and objects to be handled to many currently available robot interfaces.

REPRESENTATIVE EXHIBITORSFor example, in addition to introducing its Camera Link-based, 1004 x 1004-pixel, 48-frame/s A202k progressive area-scan camera, Basler Vision Technologies (Exton, PA; www.baslerweb. com) disclosed partnerships with National Instruments (NI; Austin, TX; and Matrox Imaging (Dorval, Quebec, Canada; to bundle and sell IEEE 1394 starter kits.

CCD cameras provide full-frame images at 12 frames/s or half-line resolution at 24 frames/s via a Camera Link or a LVDS 10-bit digital output. The Cohu DCR 1/2-in. monochrome camera features a 768 x 494-pixel resolution, an integrated lens, RS-170 video output, and 30 frames/s. The Cohu alignment image/reader camera provides a 1/2- or 1/3-in. monochrome RS-170 or CCIR imager format, 768 x 494-pixel resolution, and fixed shuttering at up to eight levels.

In the Sensor Expo area, National Instruments showed its NI-IMAQ for IEEE 1394 camera software for color-image acquisition at 30 frames/s and up to a 640 x 480-pixel resolution. This software contains a set of Virtual Instruments and C functions with which professionals can create LabVIEW and Measurement Studio programs. It enables the connection of an IEEE 1394 camera to a laptop computer for image acquisition. Then, using IMAQ Vision image-processing software permits the processing and analyzing of the acquired images.
