UNIVERSAL ROBOTS, the Danish manufacturer of flexible industrial robot arms, has released the third generation of the lightweight robots, the UR5 and UR10. Special features of the revised robot arms are the true absolute encoders, the eight new adjustable safety rated functions, twice the number of built-in I/O's, and the improved possibilities for connecting equipment to the control boxes.
Since the first UR robot entered the market in December 2008, Universal has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide. The company is headquartered in Odense, Denmark where all development and pro-duction is carried out.
According to the company there is a continuation of the safe human - robot collaboration in the new generation; additionally, the safety system of the new generation is now certified by TUV. Well-known characteristics such as the ease-of-use and the quick ROI remain.
The robot arms UR5 and UR10 are equipped with numerous new features. Still, Universal Robots remains true to its approach of user-friendly lightweight robots. The visual appearance of the six-jointed arm with a payload of 5/10 kilos remain unchanged.
"We are the only manufacturer of lightweight robot arms which already has a long lasting experience in a wide variety of industries," said Enrico Krog Iversen, Universal Robots CEO, on the latest developments.
"Our R&D department worked hard in order to integrate input and feedback from end users in our product development"
The technical innovations at a glance:
True Absolute Encoder
A central innovation of the new generation of UR robots is the True Absolute Encoder. This technical improvement enables a faster startup of the robot arms. The absolute position is recognised right after the switching-on, eliminating the need for jogging during initialisation of the robot arm. For this reason UR5 and UR10 are now suited for an automatic start-up - even though no battery is needed for this function.
"With the integration of the True Absolute Encoder, our robot-arms can be integrated even more easily into other machineries while startup also becomes much faster and simpler for all applications", explained Esben H. Østergaard, Universal Robots CTO.
Patented: Adjustable Safety System
The safety settings of the latest generation of Universal Robots' lightweight robots can be adjusted for each specific solution. The robot arm can run in two operating modes of the safety functions; a normal and a reduced one. A switch between safety settings during the robot's operation is also possible. To achieve this, eight safety functions are monitored by the new patented safety system: Joint positions and speeds, TCP positions, orientation, speed and force, as well as the momentum and power of the robot. The settings can only be changed in a password protected area. All these safety functions are safety rated PL d and certified by TÜV.
"Our new patented safety concept is a logical development of our previous robot arms. The revised UR5 and UR10 can be operated in different modes depending on the context. For example, when a human enters the robots work-cell, it can continue to operate in reduced mode, and then resume full speed when he leaves again. Or the robot can run full speed inside a CNC machine, and then reduced speed when outside", says Østergaard.
TÜV Certification of UR safety 3.0
The safety system UR Safety 3.0 of the new generation UR5 and UR10 from Universal Robots is certified by TÜV Nord and tested in accordance with EN ISO 13849:2008 PL d and EN ISO 10218-1:2011, Clause 5.4.3.
Sixteen additional digital I/Os, which are easy to configure either as digital signals or as safety signals, a revised design of the control box and a rebuilt controller are further improvements.
Focus on flexibility and user-friendliness
The six-jointed, cost-efficient robot arms UR5 and UR10 are especially suited for small and medium sized businesses. Thanks to their light weight and their user-friendly handling via touch pad, a wide range of applications can be programmed quickly without complex training or deep technological knowhow.
"With our flexible robot-arms, we address a broad target group - whether it is (un-)loading of CNC machines in a ten-man firm or a gluing-process at an automotive manufacturer, everyone benefits from our robots. Because they perform the dull or harmful jobs that needed to be done by humans before", said Iversen.
