Rotation: 360° in 1 sec.; payload: 3 kg (6.6 lbs.); radius: 500 mm (19.7")
The UR product family
Universal Robots recently launched its new UR3 robot at Automate 2015. The new compact tabletop robot weighs only 24.3 lbs. but has a payload of 6.6 lbs., 360° rotation on all wrist joints and infinite rotation on the end joint. These features allow the UR3 to work side-by-side with employees.
CTO and Co-founder of Universal Robots, Esben Oestergaard, led the three-year development phase of the new addition to the UR robot family. "With the UR3, tabletop automation is easy, safe and flexible; a single worker can accomplish what traditionally would be a two-person task by having the UR3 robot as a third-hand helper," said Oestergaard. "It is an ideal choice for applications that require 6-axis capabilities where size, safety and costs are critical.
"UR3 is an optimal assistant in assembly, polish, glue and screw applications requiring uniform product quality. Our new robot can also be used in a separate workstation mounted on the table, picking, assembling and placing parts in optimized production flows. Because of its compact form and easy programming, it is easy to switch it between tasks to meet agile manufacturing needs - making total cost of ownership low and payback period fast."
UR3 applications span manufacturing industries from medical devices to circuit boards and electronic components.
"A big demand driver will be the automation of production in confined environments," said Oestergaard. "With the UR3, we can now fit a 6-axis robot into more assembly and manufacturing lines where erecting large safety enclosures would not be feasible. The UR3 is ideal for relieving employees from working in environments with toxic or hazardous materials, and that scenario will also drive the adoption of UR3 robots."
UR3 has 15 advanced, adjustable safety settings. One of these is the force sensing that enables the UR3 to limit the forces at contact if the robot collides with an employee. The new robot has a default force sensing of 150 Newton but can be set to stop if it encounters a force as low as 50 Newton in its route.
The UR3 features easy programming technology combined with infinite rotation and improved force control. The robot can pick up screws, mount and tighten them applying the correct torque. In gluing applications UR3 can dose exactly the same amount of glue with constant and steady pressure along a narrowly defined path.
The UR3 features the same 0.1 mm repeatability as the UR5 and UR10 robots and can follow the outline of a surface - such as the aluminum edge around a smartphone - by feel rather than through the programming of precise movements and coordinates, which otherwise would require more than 100 data points programmed into the application.
"With the UR5 and UR10 robots, we see end users integrating our robot arms in applications and industries that we did not initially expect," said Oestergaard. "I am sure we will be equally surprised to witness the adaptation of the UR3 into new scenarios where robots have not ventured before."
