Collaborative Robots By Acieta
A collaborative robot can share a workspace with humans: physical separation is not required. This is a break from past practice where robots had to be caged to avoid harming anyone who got in their way. Now, with the change of sensor and robot controller technology, a robot can reliably detect and adapt to intrusion into its work envelope, meaning physical barriers are no longer essential for safe operation. Updated robot safety standards account for these advances but require the robot to possess at least one of the following characteristics to work collaboratively: Safety-rated monitored stop Cell-hand guiding Speed and separation monitoring Power and force limiting Robots employing the power and force limiting approach have compliance in case of impacts, but also lack speed, accuracy...

Robot Programming By Acieta
If you've never programmed a robot before it can seem daunting. Tool Center Points, coordinate systems, avoiding singularity problems and so on. The reality though, is that basic robot-programming skills can be picked up quickly by anyone with a background in manufacturing technology. The biggest hurdle most users face is switching their thinking from the x-y-z linear motions of a CNC machine to the joint rotations of an articulated robot. In CNC programming moving the tool in a straight line only needs one axis. Doing the same with a robot takes the simultaneous rotation, at different speeds, of multiple axes. While novice robot programmers may not find this very intuitive, with training and practice programmers can quickly become proficient. To help the newcomer, robot manufacturers... Read More
