Collaborative, synchronous robots serving machines and cells

Abstract

Multi‐arm, collaborative, synchronous robots are gaining acceptance in industry, because of the cycle time reduction, productivity increase, flexibility and quality gain, distributed control, layout design/simulation, and programming support robot manufacturers and system integrators can offer. On the negative side, when things go wrong such systems are more complex to recover, and maintain, than non‐networked and non‐distributed controlled individual robots. In this paper, we introduce some of the most important engineering, and technology management principles that collaborate robots and their users and should be kept in mind while developing such systems, and/or planning for such applications.

Decision making logic for flexible assembly lines reconfiguration

“…robots communicating with each other for carrying out common tasks [14]. The cooperating robots' applications comprise characteristics such as [15,16]: Workspace sharing, Motion synchronisation, Program synchronisation and Linked motion.…”

Control Model for Collaborative Manufacturing: An Integrated Opened Framework for Human-Robot Collaboration

“…Each traditional robotic workcell could be composed of multiple cooperating robots, used to lower the number of fixtures and the process cycle time. On the contrary, this solution is more complex to maintain and recover in case of faults [27]. Collision avoidance is a further issue that the framework should solve: a proper solution is to define multiple robot trajectories is such a way that they do not collide [27].…”

Verification of the UR5 robot’s properties after a crash caused by a fall of a transferred load from a crane

“…Collaborative robots are particularly suitable where robot arm cooperation with man is required, we do not require high speeds and we have limited space to install the robotic workplace. 2,3 The number of robots deployed from the UR in industry exceeded 10,000 units in 2016. They are deployed in various industries, and especially in an environment, where cooperate with human.…”
