MELFA-3D Vision

MELFA-3D Vision

This 3D vision sensor for small robots is small and performs high-speed and high-accuracy measurements.
This sensor is optimal as a replacement for a parts feeder.Its unique model-less recognition processing enables high-speed picking.

Small and light

  • Small and light (Camera head part: 146 x 87 x 137mm, approx. 0.9 kg)
  • It can be used for eye-in-hand and can be fixed.

High-speed and high-accuracy measurement

  • This sensor enables high-speed recognition of 1.2 seconds at the earliest (model-less recognition) and high-accuracy measurements.
  • The minimum measuring error of approximately 0.3 mm.

As a replacement for part feeders

One of the following two recognition methods can be selected.

  • Model-less recognition: The position of a workpiece is recognized without registering its model.
  • Model matching recognition: The pose of a workpiece is recognized using a 3D-CAD model.
  • This sensor is more inexpensive and conserves a smaller footprint than a part feeder (when multiple parts are used). Retry operation can reduce stoppage.

Good connection compatibility

Good connection compatibility supplied as a robot manufacturer

  • This sensor can be connected directly via LAN equipped with a controller as standard.
  • The sensor can be set and its operation can be checked easily using a personal computer for setting.
  • When the sensor is running, the personal computer is not required.
  • The sensor has the coordinate calibration function of robots and vision sensors as standard installation.
  • The dedicated commands added to MELFA-BASIC V can be used to control the sensor.
