UR (Universal Robots) and robolink robots acquire a 5-times larger action radius thanks to a completely new solution
igus now offers a directly ready-to-connect 7th axis so that a robot can move over a distance of several metres. The new complete system consists of a maintenance-free drylin ZLW toothed belt axis with corresponding adapter plate, switch cabinet, cables and software integration. For easy integration of the axis and therefore of the robot, igus has developed two adapter kits for robolink and UR robots. They enable fast and, above all, cost-effective low cost automation.
Robots insert workpieces into a milling machine, dispense chocolate bars from vending machines and place crates on pallets, which are then stacked. But how can they move vertically, horizontally or overhead in a flexible manner? The answer is a 7th axis. Specifically for linear adjustment, igus has developed a lubrication-free, lightweight flat axis with a stroke of up to 6m and a positioning accuracy of 0.5mm with the help of its drylin linear construction kit. To ensure that the axis can be easily combined with a robot, igus now offers overall solutions for UR3, UR5 and UR10 robots (Universal Robots), robolink DP robots and DCi robots. „A customer who acquires the new complete system receives, on the one hand, an adapter plate for easy attachment of the robot and the energy chain to the axis and, on the other, the corresponding integration solution, in other words the switch cabinet with cables, motor controller and the respective software solution“, explains Alexander Mühlens, Head of Automation Technology at igus GmbH. „If a robolink robot is used, the 7th axis can be easily controlled by means of the igus robot control software. For UR robots, we supply an UR-CAP as a direct integration solution, including all the electrical modules needed.“ This means that the robot can be installed and put to work within just a few minutes.
Ready-to-connect 7th axis in desired length
Users can configure the appropriate complete solution online at https://www.igus.eu/info/configurator7th-axis-for-universal-robots. The 7th axis is supplied by igus as a complete system that is ready to connect immediately, consisting of a drylin ZLW-20 toothed belt axis in the desired length exactly to the millimetre, plus the connecting cables, the switch cabinet, the power electronics, the software integration and the corresponding adapter set. Alternatively, the adapter set is separately available consisting of adapter plate and control system.
igus offers to accompany medium-sized companies into the automation age with an online platform for low-cost automation
Cost-effective robots with components from various manufacturers that can be configured and ordered online in just a few clicks. The Cologne-based motion plastics specialist igus offers this service with an online platform rbtx.com for Low Cost Robotics. Thanks to a modular system, even small medium-sized companies will achieve automation for a few thousand euros.
A pick-and-place robot heads towards the conveyor belt, reaches for a small electrical component, turns it over and places it in a testing machine. Thousand times a day. Faster and tireless than the best worker. Such scenarios are commonplace among global players. The industry giants are steadily increasing the level of automation and thus increasing the competitive pressure on small and medium-sized enterprises. But many small companies are avoiding the topic. The investment costs are too high. Too confusing and complex is the interaction of the components of different manufacturers – including mechatronics, control systems and software.
An entry barrier that is unnecessary, says igus. The company specialises in the development of Low Cost Robotics and has therefore introduced the online platform rbtx.com at the Hannover Messe 2019 in cooperation with other manufacturers. „As far as mechanics, bearings, motors and gearboxes are concerned, we can offer competent advice to interested parties. However, it is also a fact that other companies are leaders in terms of cameras, grippers or control software,“ says Stefan Niermann, head of the newly established Low Cost Automation division. „This is precisely one of the reasons why an online platform that combines the different skills makes sense, so that the customer can quickly get the right robotics solution for them.“
Make your own robot with just a few clicks
The idea is to enable customers to assemble their own robot solution with just a few clicks of the mouse. The basic electro-mechanical structure is the „rohbot“ from igus, among them articulated-arm robots, delta robots and Cartesian robots. In the next step, the user supplements this basic structure to include individual components from various manufacturers, such as grippers, cameras, GUIs, power electronics, motors, sensors and control systems. The advantage: All components are compatible with each other.
„The concept intended for companies, start-ups, research institutes and mechanical engineering companies offers fast, customised robot solutions at low starting costs of just a few thousand euros, which will pay for itself in a short time and bring quick profits“, explains Niermann. „What we are talking about here is a low-risk way of entering the era of automation and investing in the competitiveness of tomorrow.“ Another advantage: All manufacturers would be able to continuously expand the online platform with new components. The users always have a clear access to a rapidly developing market segment.
Ready-to-connect articulated arm robots for 5,000 euros
igus has experience with Low Cost Robotics. The company has been developing automation solutions for order picking, feeding, quality assurance and assembly for many years. These include robolink DC – a modular system that allows users to assemble articulated arms with a robust and lightweight plastic housing, gearboxes and motors into a robotic arm of their own. The offer also includes robolink DCi, a pre-configured, ready-to-use automation system. It consists of a 4 or 5-axis robot and a control system that is integrated at the base of the gripper arm in a space-saving manner. The control software of the partner Commonplace Robotics is specifically designed for the robolink DCi. With it, movement sequences can be set as intuitively as on a smart phone. PC and control cabinet are not required.
In order to keep pace with the rapid development of the global automation industry, igus continuously invests in research and development work. As a result, the engineers succeeded in laying the cables inside the arm in the new generation of the DC system. A tidy and space-saving design that predestines robots for human-robot collaboration. The compact and lightweight articulated arms make comprehensive use of the advantages offered by igus motion plastics: light, lubrication-free and maintenance-free, durable and cost-effective in production. As a result, small, configurable quantities can be created just as large quantities for mechanical engineering companies and robot manufacturers. The clearance of the new arms has been further reduced as a result of the joint kinematics, an innovation that enables greater precision of the robolink. You can place parts weighing up to three kilograms with a precision of +/- 0.5 mm in a workspace with a diameter of almost 790 mm. Compared to conventional industrial-grade robot arms, which are currently not available under 15,000 euros, the new robolink DC arm (as a five-axis model) makes a significant difference at 3,400 euros. This price can be realised because many components of the articulated arm robot, such as the strain wave gear in the fifth-axis, are not made of metal, but of the so-called tribo-plastics. „These high-performance plastics not only enable cost-effective production, but also display their advantages in ongoing operation,“ says Niermann. „Robot components made of tribo-polymers do not require any lubricants and are therefore maintenance-free. In addition, they are stable, corrosion-free and lightweight at the same time.“
Modular system for development and research
Anyone who believes that they can only find turnkey solutions at igus is mistaken. Even experienced engineers will get something for their money. This is where robolink Apiro comes in – a modular system consisting of joints, profiles, gearboxes and motors of various sizes, with which designers can implement automation systems. Even very complex systems! For this purpose, igus has decoupled the motor and gearbox from each other and developed a novel worm gear made of tribo-polymers, with which, for example, simple SCARA kinematics can be implemented. The joints are attached by means of a multi-functional profile made of aluminium. Multiple joints can be connected in a series if desired. „Thanks to the modular system, there are countless combination options. There are really no limits to the imagination,“ says Niermann. „Users of the Apiro modular system therefore include not only mechanical engineers, but also training institutions and development and research departments.“
Room linear robots and delta robots as a low-cost option
The ABC of automation technology includes room linear robots and delta robots. For the low-cost sector, igus has therefore developed room linear robots in several extension levels, which are available from 1,799 euros. They consist of pre-configured linear modules and aluminium linear axes and NEMA stepper motors. With the small complete solution, loads of up to 2.5 kilograms can be transported in a workspace of 400x400x100 millimetres at a maximum speed of 0.5 metres per second. Two ZLW toothed belt axes and one GRW gear rack axis ensure precise guidance and lubrication-free operation. The room linear robots are used, among other things, in pick-and-place applications in the fields of medical technology and microelectronics.
The delta robots are also suitable for pick-and-place tasks. They are based on three ZLW toothed belt axes, NEMA motors and lubrication-free coupling joints and can position in an installation space up to 420 millimetres components weighing up to one kilogram with a precision of +/- 0.5 millimetres, at a speed of up to 60 picks per minute. At lower speeds, the system even carries up to five kilograms. The price of the robot is less than 5,000 euros. „If users have their own switch box, the costs including integration are between 10,000 and 15,000 euros,“ says Niermann. „The costs are paid off after a maximum of half a year. Afterwards, the company makes profit with automation.“
Automate simple tasks cost-effectively
The Low Cost Automation solutions from igus are also relied upon by the Langhoff family. In their small enterprise, the family breeds giant red worms, which are, for example, used by anglers, as food for animals, for hunting or as a natural fertiliser producer for the garden and greenhouses. Langhoff developed completely new machines to fully automate the feeding and watering process with lubrication-free and durable drylin room linear robots from igus. The monotonous feeding and watering steps no longer need to be done by a person full-time so that they can focus on more demanding tasks. „With the new plant, feeding and watering can be carried out around the clock, even when there is a shortage of staff. In addition, errors are reduced to an absolute minimum,“ explains Martin Langhoff, owner of Superwurm. There are already companies around the world who have identified the same market niche as the Langhoff family. However, labour-intensive worm breeding is hardly automated there. That’s what the Langhoffs want to change in their business. The plan is to double the current level of automation in the worm farm. „Small businesses need to use affordable and easy automation solutions for production and warehousing, such as those from igus, to keep up with the big ones,“ says Martin Langhoff.

ROI schnell erzielt dank Low Cost Automation von igus
Der ROIBOT Wettbewerb zeichnet Low Cost Robotics Anwendungen aus, die zu einem schnellen Return on Investment geführt haben. Zum Einsatz kommen dabei sowohl robolink Gelenkarmroboter, drylin Delta Roboter sowie Portal-Roboter von igus. Eine Fachjury aus Forschung, Fachpresse und Hersteller wählt die Gewinner aus und vergibt ein Preisgeld von 5.000 Euro an den ersten, 2.500 Euro an den zweiten und 1.000 Euro an den dritten Platz. Der Preis wird zum ersten Mal in diesem Jahr gemeinsam mit dem Publikumsaward vergeben. Auf www.roibot.de erhalten Interessierte nicht nur Ideen und Inspiration für ihr eigenes Projekt, sondern können auch bis zum 30. September für ihren Favoriten abstimmen. Zum Beispiel für Pick&Place-Anwendungen wie die Pilotanlage im VW Werk Emden, in der ein robolink D für das automatisierte kontinuierliche Handling von Bauteilen für den Passat/Arteon zuständig ist. Im System von Apostore übernimmt ein robolink D das Pick&Place von Medikamenten in Apotheken. In beiden Fällen spart die kostengünstige Automatisierung monotoner und einfacher Aufgaben unmittelbar Betriebskosten ein. Ein anderes Beispiel ist der Manipulationsroboter – eine Drohne mit Roboterarm – der Universität Sevilla. Er kann entlegene oder in großer Höhe befindliche Arbeitsbereiche einfach und schnell erreichen und eignet sich so für Inspektions- und Wartungsanwendungen an Öl- und Gasraffinerien, Stromleitungen oder Windkraft- und Solaranlagen. Der kartesische 2-DOF-Manipulator besteht aus zwei leichten und wartungsarmen Lineargleitführungen sowie drei Schlitten.

Fast entry into Low Cost Automation using a digital twin in intuitive robot control
To programme robots with ease, igus has now developed control software for its Low Cost Automation solutions. igus robot control is available online free of charge and offers the user an easy introduction to automation. Different robot kinematics can be programmed and controlled. A digital twin simulates the movements. In this way, the user can programme a suitable solution before purchase. The robot hardware, for example, a linear robot with switch cabinet, is offered by igus from as little as 5,000 euros.
Picking up goods from a box, helping to take samples and dispensing cans from a machine – all done by robots! Whether articulated arm robots, delta robots or linear robots: igus has all three kinematics as Low Cost Automation solutions in its portfolio. To enable users to try out in advance which robot is best suited for their application, igus now offers igus robot control, a software for the simulation and programming of all igus robots. „As a mechanical engineering company, we are very familiar with the different kinematics, so the next logical step for us was to develop a correspondingly simple and intuitive robot control system“, says Alexander Mühlens, Head of automation technology at igus GmbH. The special feature: the software is available online free of charge and license-free. In the software there is a digital twin for all igus robots, which can be simulated and taught like the real robot. The robot control system is also used later to programme the robot intuitively. Every programming can be applied to the real robot afterwards. The complete hardware package, for example, a drylin linear robot with integrated control system in the switch cabinet, is available from 5,000 euros.
Easy programming of robots
With igus robot control, the user can freely move all axes of the digital twin via a 3D interface. By means of a teach-in function the robot can be programmed very easily, even without a robot connection. To do this, the user must manually move the robot to the desired position and define how it is to be moved. The process is repeated until the desired motion profile is created. Matching end effectors, such as grippers, are easy to add and the tool centre point adjusts automatically. Virtual boxes can also be installed, for example, to prevent the robot from colliding with a machine. The igus robot control can also be connected to a higher-level control system, either via interface communication with Digital IO or via Ethernet communication using IP address. The igus developers want to expand the control system even further: „In the future, we want to offer cloud services such as vision integration, remote commissioning and also online training for a small cost, which the customer can book. Further services such as image evaluation via webcam or bin picking solutions are planned as cloud-based solutions“, says Mühlens.
Köln, 18. August 2020 – Viele Schlaganfallpatienten weltweit leiden an halbseitigen Lähmungen. Exoskelette wie Harmony von Harmonic Bionics können dabei helfen die Nervenbahnen in Armen und Schultern wiederaufzubauen. Damit sich das robotergestützte System in der Physiotherapie schnell auf die unterschiedlichen Körpergrößen anpassen lässt, vertrauen die Entwickler auf die leichte, schmier- und wartungsfreie Gleitlagertechnik von igus.
16 Millionen Menschen erleiden jedes Jahr weltweit einen Schlaganfall. Damit sich die Patienten in der Physiotherapie wieder rehabilitieren können, hat das amerikanische Unternehmen Harmonic Bionics, mit Unterstützung der National Science Foundation, ein Exoskelett speziell für die Heilung von Muskelschäden entwickelt. Der Roboter mit dem Namen Harmony entlastet das Schultergelenk, den Schultergürtel und maximiert den Bewegungsradius des Patienten. So soll das System eine natürliche und umfassende Therapie der Arme ermöglichen. Harmony setzt dafür auf eine Bilateral Sync Therapy (BST). Hierfür registriert der Roboter die gesunden Armbewegungen und synchronisiert sie an die vom Schlaganfall betroffene Seite, um die Wiederherstellung der Nervenbahnen zu unterstützen. Damit sich das Exoskelett mit dem menschlichen Körper bewegen kann, muss die Roboterachse richtig auf den Patienten eingestellt sein, denn eine falsche Justierung kann zu Verletzungen der Gelenke führen. Für eine schnelle Anpassung von Harmony griffen die Entwickler auf Linearführungen und Gleitlager des motion plastics Spezialisten igus zurück.
Schmierfrei und schnell angepasst
Schienenführungen der drylin Serie T und R, Linearlager drylin R und iglidur Gleitlager ermöglichen eine leichte Justierung des Systems an die Körpergröße, Armlänge und Schulterbreite des Patienten. Die eingesetzten Polymerlager aus dem Hochleistungswerkstoff iglidur J zeichnen sich durch ihre hohe Verschleißfestigkeit und Langlebigkeit aus. Durch den Verzicht auf externe Schmiermittel sind die Lager komplett wartungsfrei, zudem sauber und hygienisch und damit optimal für die Medizintechnik geeignet. Alle Bauteile bestehen aus leichten Materialen wie Kunststoff und Aluminium. Das Design ist so kompakt, dass es sich in das schlanke Design des Roboters integrieren lässt. „Dank des Einsatzes der igus Polymerlagertechnik kann das Exoskelett jetzt innerhalb von Sekunden auf den Patienten angepasst werden,“ zeigt sich Rohit John Varghese, Leiter Forschung & Entwicklung bei Harmonic Bionics begeistert.
