Two arm cobot
19 October 2016
Du-Aro from Kawasaki Robotics is a two arm collaborative robot designed to function as a quickly and easily installed co-worker to meet fluctuating production demands.
Where production runs are limited in volume, justifying costly dedicated assembly or packaging tooling can be difficult. Finding operators to integrate on production lines at short notice, and for limited periods, can be an even bigger problem; so having a co-worker robot that just wheels into position when needed is a natural progression for manufacturing automation.
Two SCARA configuration arms sharing the same central pedestal allow Du-Aro to provide the same working envelope as a human operator. Controlled by a single controller, co-ordinated arm movements can be programmed easily either by ‘lead through’ or by using a tablet or robot teach pendant.
Low-power motors and speed reduction helps Du-Aro to co-exist with human operators and in the event of a collision or contact with any object or an operator, collision detection sensors immediately stop all motion.
“The concept of Du-Aro is based around the need for ease of integration and flexibility," explains Kawasaki Robotics UK sales manager Ian Hensman. “Integrating it onto a production line conveyor with other operators simply requires it to be wheeled into position and the arms to be physically guided through the required motions. Of course sensors are required to provide inputs to the controller but even this area has been simplified with the inclusion of optional vision cameras.”
Catering for the non-robotics specialist, the Du-Aro’s controller can be supplied with embedded vision processing software. A range of application specific cameras, light sources and grippers are available that simply plug into the robot’s arms.
“We believe we have made the whole process of programming very straight-forward from programme routines and sensing, through to simulation of the working area and operation. However, support we realise is always essential and our application engineers are always on hand to provide assistance and provide essential tips as and when needed,” concludes Hensman.
