Tracking in Industrial Environment

Coordinate measurement is a standard task in today's industrial applications. A coordinate measurement machine for industry has to meet several demands, including robustness, accuracy, usability, and flexibility. With our TRACKPACK /IS cameras we have designed a new tracking solution for the industrial environment.

With our tracking an application now has eyes and the ability to check and approve all production steps, such as

  • is the worker or the robot on the right position?
  • where is the object to be worked on?
  • is the right tool being used?
  • what should be done on this position?
  • is the torque correct for this screw?
  • are all screws processed with the individual adjustment?
  • where is the error? and so on…

In the following pages you will find further descriptions of the use of ART systems in industrial applications.

Tracking of Tools

Tool Tracking combines the flexibility of manual processing with the accuracy needed for quality assurance. ART brings experience from several projects concerning tool tracking for industrial and medical applications to all their tracking solutions.

Quality assurance

Using the 3D information (position and rotation) of the tracking system, Tool Tracking can check and log if every working position has been stepped through with correct adjustments, and in the correct order – in fact it may be difficult to achieve this sort of quality assurance by any means other than a tracking system.

  • Tool configuration - The system can give assistance by automatically configuring the tool (for example, a screwdriver's torque) to the current working conditions.
  • Guidance for the worker - The worker can be directed from one working position to the next, by using a display mounted onto the tool or a monitor next to the working space which shows the worker the next position on a picture. The tool can be locked until the worker is in the right position.
  • Documentation – Every position (e.g. screw) can be recorded with the time, the angle and the torque – depending on the application of each customer.

Training

Physical prototypes or products can be very costly and have limited availability. In such cases, training tasks can be performed in VR as well. In these applications the user holds physical props, which are tracked, and performs the movements which should be trained. Using a tracked device allows the application to verify the movement and give feedback on performance. One task trained in VR is the movement of a sealing gun.

Robot Tracking and Teaching

While the use of industrial robots is nowadays commonplace, research in robotics is ongoing. This applies to the improvement of usability of standard industrial robots as well as to the development of new designs.

In robot research and development, ART systems are used to precisely localize autonomous robots and limb positions. We provide tracking volumes from small laboratory setups up to large outdoor tracking areas.

In industrial robot applications, ART and our partners can help to overcome the laborious classical teaching processes such as lead-through or offline-programming, and substitute them by simpler procedures, e.g. using a pointing device.
