There are numerous benefits to using UR factory automation cobot solutions including:
- Easy programming
- Fast setup
- Flexible deployment
- Collaborative design and safety features
UR and 3D Smart Sensor Integration
To implement quality and inspection applications successfully, the UR robot requires machine vision capability for vision-guidance, 3D scanning, measurement, and pass/fail control.
Engineers using UR robots can now easily integrate LMI Gocator® smart 3D snapshot sensors into their applications. Gocator is able to provide the UR robot not only with the “eyes” it needs in order to “see”, but also the “mind” it needs in order to “think” and “do.”
Gocator 3D snapshot sensors are easily mounted onto the UR robot flange using a metal plate and connected to the sensor’s web interface from a client PC over an Ethernet connection, and add and configure the appropriate built-in measurement tools (e.g., Surface Plane, Surface Sphere, etc.) to return the required positional data. The sensor is connected to the robot controller or PC application to perform sensor hand-eye calibration, using the URCap plugin, to implement pick-and-place movement.
The user does not have to write any robot programs or calibration routines and no expertise is necessary to set up the robotic systems for factory automation applications. Advanced user who require greater flexibility and control have the option of using the Gocator Development Kit (GDK) to develop and embed their own custom tools onto the sensor and the adapt calibration routine to their own calibration target.
Gocator URCap Plugin
Sensor-robot integration is achieved through the Gocator URCap plugin, which is an application installed on the UR robot. The plugin triggers scans on the sensor and retrieves the positional information of the calibration target in the sensor’s field of view. (Note: Ball-bars are the most commonly used targets in sensor-robot calibration.)
After a sufficient number of scans, the calibration is saved to the UR robot, and hand-eye calibration (between the sensor and the robot flange) is complete. After performing the hand-eye calibration, programming nodes are added in the UR robot’s interface to instruct the robot to connect to the sensor, load a job on the sensor, trigger a scan, and return positional measurements in the X, Y, and Z axes.
Gocator URCap provides a complete vision-guided robotic with minimal cost and development time.
