The ability of robots to 'see' is vital, and of the 9 finalist products in the 2021 'Inspect' Awards, Baumer VeriSens XF/XC900 vision sensors secured first place in the ‘Vision’ category.
Baumer says that amongst other attributes it was its intelligent calibration target SmartGrid (patent pending) which proved pivotal in winning the award. It features the company's Chessboard bit pattern application. Importantly for robot operators the SmartGrid feature not only enables unique automated coordinate alignment, it also eliminates the conventional issues and limitations of manual ‘hand-eye’ coordination. The result is that only a few minutes are needed to give ‘eyesight’ to Universal Robots - and at a higher accuracy in parallel says the company.
In addition, the SmartGrid feature supports automatic teaching of image rectification for image distortion correction in real time. Basically, a simple mouse click will suffice in eliminating any impairments by lens or mounting, without affecting the following processing time. Also the teaching of 3D orientation enables automatic adjustment to distance. When converted to World coordinates VeriSens is receiving the scaling specifications directly via the SmartGrid.
Installation and calibration of these vision sensors is simplified via the VeriSens URCap interface specifically developed by Baumer to optimise robot control. Only a few steps are required to ensure the benefits of the diverse range of image processing options that this interface provides.
For the programming of the robot, only two additional commands (nodes) are necessary to realise the benefits and advantages of vision guided robotics across a wide range of control applications.
Set-up and calibration is also said to be simplified because instead of pre-determined waypoints, free positions are used on which objects are then visually recognised while the already established functions are able to check for object overlaps and gripper clearances. Furthermore, VeriSens sensors can also be used for additional functions such as verifying free storage areas, fulfilling quality controls of objects which are in various positions, as well as identifying and measuring objects
