How to build a collaborative robotic cell with KUKA cobot LBR iiwa

Показать описание

LBR iiwa is KUKA's robot for collaborative applications, i.e. applications in which man and robot share spaces.

In this video we explain how to create a collaborative cell with the KUKA LBR iiwa collaborative robot in compliance with ISO 10218 and technical specification TS 15066. In particular, all moving elements, such as end effector covers, gripping devices, objects to be moved, have been designed to comply with current safety regulations and to guarantee low impact torques and low crushing pressures with the operator's body parts, as identified during the risk analysis.

We also show you how easy it can be to program a robot through the 'Teach by Demonstration' functionality. The operator teaches the robot the movement that it will have to perform later on its own, showing it the path to replicate. The operator then shows the path and the objects to be moved, which will be recorded continuously or punctually by the robot and then re-executed autonomously, respecting the speed and path previously learned.

Possible impacts with the operator are managed with safe functions that interrupt the movement of the robot with safe STOP or paired STOP, according to what the risk analysis has established for the current application. The proposed technologies allow easy and intuitive re-planning of trajectories without the need to change the programming code.
