Lightweight robot
Take it iisy!
A rosy future is predicted for human-robot collaboration. No wonder, as cobots relieve humans of all kinds of work. Kuka is also developing lightweight robots for HRC. The latest member: LBR iisy.
With the help of human-robot collaboration, workers and lightweight robots can form a productive team in production. Thanks to their cognitive superiority, humans are the strategists, while robots contribute their repetition accuracy, strength and endurance to the collaboration while adhering to prescribed safety standards. This will also gradually improve the capabilities of robots: they will become better at collaborating with humans, master gesture and voice control, perceive their environment and intuitively integrate themselves into changing processes. Intelligent machines will be mobile and capable of learning, sharing knowledge, acting in a swarm and thus playing a key role in the factory of the future.
Optimized for MRK
In order to meet future requirements such as easy handling and flexible manufacturing processes, robot manufacturers are launching new lightweight robots, or LBRs for short. Kuka is no exception. With the sensitive iisy lightweight robot, the Swabian robot specialist is expanding its portfolio in the field of human-robot collaboration in the low payload range. The prototype of the LBR iisy was presented to a wide audience at Automatica. Following the LBR iiwa, the world's first series-produced sensitive lightweight robot for industry, series production of the automation specialist's second sensitive robot will begin in 2019.
Entry into everyday working life
The name says it all: LBR iisy is easy to use. It is aimed at a target group that has process knowledge, but not necessarily programming knowledge. LBR programming is quick to learn, easy to understand and can be implemented immediately. The user-friendly system adapts to the user's level of expertise with different operating levels - from Java programming to simple manual teaching of the cobot. This principle is intended to pave the way for robotics in everyday working life in the long term.
For changing automation tasks
The LBR iisy is suitable for frequently changing automation tasks where fast reactions are required in the process. It is designed for simpler assembly tasks, while the LBR iiwa, for example, can also perform more complex tasks in the payload range up to 14 kilograms. The two robots complement each other. The LBR iisy supports all essential industry standard functions, such as OPC UA, fieldbus protocols, digital and analog I/Os, safety and much more. This means that the LBR iisy can be integrated into existing industrial environments. The iisy weighs 18.8 kilograms and meets PL d / Cat 3 safety requirements. With a reach of 600 millimetres, the new lightweight robot has a payload of three kilograms. It can be used in a very space-saving manner and offers optimum utilization of the workspace. Commissioning should take less than 30 minutes and reprogramming for new tasks should be quick and easy. Another advantage: even in the event of unplanned interruptions, it remembers every movement or activity carried out and can resume work ad hoc without having to be retrained. Its six axes are equipped with the joint torque sensors already used in the LBR iiwa.
Future fields of application
The fields of application for cobots will not be limited to assembly. One logical development, for example, is the combination of HRC and mobility. If the strengths of a sensitive lightweight robot are combined with a mobile and autonomous platform, the robot becomes a location-independent and flexible production assistant with an unrestricted workspace.
Logistics centers are one possible application scenario. In an automated item picking application, for example, cobots are able to pick items provided by storage systems directly from bins using integrated image processing systems. This allows humans to concentrate on process refinement tasks.
