Universal Robots (UR), a global developer and manufacturer of flexible and user-friendly industrial robots, has launched its new UR3 robot, one of the world’s most flexible, lightweight tabletop robots designed to work alongside humans.
The latest state-of-the-art offering from UR’s market-leading range of collaborative robots, the new UR3 has been created to perform light assembly tasks and for automated workbench scenarios.
Launched in the market following a three-year development phase, the UR3 is an affordable 6-axis, collaborative tabletop robot featuring a payload of 3kg and weighing a mere 11kg. The robot allows for 360-degree rotation on all wrist joints and infinite rotation on the end joint.
Universal Robots CEO Enrico Krog Iversen explains that the UR3 is a compact tabletop robot with the capabilities to function efficiently as the second member of a two-man team or as a standalone operator. UR is confident that the UR3 will revolutionise the manufacturing industry, especially during the production of medical devices, circuit boards and electronic components that require speedy, precise and consistent movements between waypoints.
UR3 combines UR’s industry-leading easy programming technology with infinite rotation and improved force control to perform a series of expert functions from pick and place and assembly to polish, glue and screw applications, enabling manufacturers to maintain uniform product output. For example, the robot can pick up screws, and mount and tighten them while applying the correct torque.
Shermine Gotfredsen, General Manager, APAC, Universal Robots commented that the new UR3 meets the needs of businesses in the APAC region that are determined to innovate their production lines using a nimble robot with assured lower cost of ownership and quicker payback period. The UR3’s compact form and easy programming make it the ideal solution to meet the agile manufacturing needs of these businesses.
The UR3 is also ideal for deployment in confined workspaces where the construction of large safety guarding is not feasible. The robot can be tasked to operate in environments with toxic or hazardous materials, giving workers peace of mind as well as improving job satisfaction and productivity levels at the same time.
Safety is ensured with 15 advanced, adjustable safety settings including a unique force-sensing feature that enables the robot to limit the force on impact if it encounters an obstruction. As a default setting, the new robot is able to sense a force of 150 Newton but can be programmed to cease all movements if it encounters a force as low as 50 Newton along its path of motion.
The UR3 features the same 0.1mm repeatability as the UR5 and UR10 robots and can follow the outline of a surface such as the aluminium 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.
Gotfredsen concludes that the UR3 will give manufacturers the edge in today’s High Mix Low Volume environment where the ever-changing production line is equipped with an easy-to-program and lightweight solution for increased flexibility.
UR3 robots find application in gluing, painting, tightening screws, soldering, pick and place, laboratory work, fume hood tasks, and operating hand tools.
