“Our new robot braking distance function for RobotStudio equips the user with information about a robot’s real-world movements with an unprecedented level of accuracy,” said Antti Matinlauri, Head of Product Management for ABB Robotics.
This is especially beneficial in collaborative applications where operators must be confident that a robot has stopped before approaching it. This allows the exact movement of the robot to be simulated in RobotStudio, enabling the user to determine the correct size of the safety zone required, and the ideal location of features, including light curtains, safety fencing and controllers.įor applications using ABB’s SafeMove software, the data on the robot’s final position can be used to determine the size of the ‘green,’ ‘amber’ and ‘red’ zones where the robot will either continue working, slow down or come to a halt, depending on the location of the operator. The new RobotStudio function uses ABB’s superior motion control technology to predict the robot’s movements with millimetric precision. To compensate for the variability in stopping distances, engineers designing robot cells traditionally oversize them to allow for additional movement as the robot comes to a stop, which uses unnecessary space on the factory floor.
These factors, individually or combined, can result in the robot coming to a halt outside of its safety zone, sometimes by several meters. Predicting exactly where a robot will stop depends on a range of variables, including speed, payload and the robot’s own inertia. Enabling the robot’s braking distance to be accurately calculated, the function overcomes the need to add safety margins into cell designs, enabling space savings of up to 25%.
ROBOTSTUDIO WORLD ZONES SOFTWARE
