ROBOT CALIBRATION


Robots are historically repeatable but not accurate. Today many automation tasks require improved process control and a higher order of robot accuracy than that delivered by robot manufacturers including aerospace machining, drilling and assembly operations. API offers robot performance verification and calibration services providing improved control of manufacturing processes. In additional improved robot accuracy and verification dramatically improves the efficiency of off-line robot programming.

ROBOT PERFORMANCE VERIFICATION


The API robot solution quantifies robot performance in accordance to ISO 9283. Robot performance verification is the process of identifying the real geometric parameters present in the kinematic structure of a robot, such as the relative positions of robot joint links. A total of 14 static and dynamic tests are perfomed to quantify a robot’s absolute performance determining robot accuracy, repeatability and identifying inherent robot joint wear.

“Our RMS robot accuracy verification solution is of significant interest to robot system integrators, robot end users and robot OEMs, particularly since robot uptake is increasing dramatically, while at the same time manufacturing operations are looking to more tightly control production processes” comments API President Joe Bioty.

ROBOT CALIBRATION


The robot is automatically driven to discrete positions using API’s Robot Performance Measurement (RPM) Software providing fully automated measurements and data acquisition and allows customization of the actual workspace under calibration. Up to 30 robot parameters can be calibrated in a completely automated run-time.

Typical applications for enhanced robot accuracy include machining, drilling, grinding, welding, cutting, inspection, deburring and 3D printing. Activities such as robot cell “cloning”, “cell mirroring” or “robot swapping” also benefit from enhanced robot accuracy by providing seamless and precise off-line robot programming. Accurate robots improve process capability as a robot positions more accurately to its commanded position negating the ‘touch-up’ of robot programs.

ENHANCED ROBOT PATH PLANNING


API’s robot enhancement service is achieved using an API’s 6 DoF Laser Tracker complimented by API’s Smart Track Sensor, which mounts directly to the robot’s end effector, allowing the laser tracker to dynamically collect X, Y, Z, and I, J, K data for each robot position in space accurately and automatically.

API's Robocal software offers both DH kinematic model and a volumetric error compensation model (VEC) to update robot accuracy using collected calibration data. Existing robot path programs can be automatically updated driving the robot to its corrected calibrated positions.

ROBOT MEASUREMENT SOFTWARE (RMS)


API’s RMS software provides a single seamless solution for robot process performance enhancement and optimization. RMS can be supplied as a Robot Performance Measurement (RPM) module or combined Robot Calibration (RoboCal) and Robot Path Plan Enhancement (PPE) module. Let API show how enhanced robot performance can benefit your process.

Once a Robot has been calibrated existing robot path programs can be automatically updated driving the robot to its corrected calibrated positions. A 12-fold improvement in robot accuracies have been achieved using API’s Robot Measuring Software.
