Epson Launches Low-TCO SCARA Robots

March 2017

T3 robots offer quicker setup and lower running costs for accelerated automation of simple material handling tasks

SYDNEY, 30 March 2017 – Epson is expanding its lineup of industrial SCARA (selective compliance assembly robot arm) robots with the launch of its new T series of robots that will offer a low total cost of ownership (TCO). The T3, the first product in the T series, will be released in limited markets beginning in late March, with a gradual rollout in other regions to follow.

In Australia Epson’s robot sales, service and support is managed by Motion Solutions Australia (Factory 2, 21 -29 Railway Avenue, Huntingdale, VIC 3166) and they can be contacted on (03) 9563 0115, on the web at or by e-mail on

The T3 is designed primarily for simple material handling applications, such as test machine loading/ unloading. It provides companies with the opportunity to free operators from repetitive and non-creative tasks such as transporting components, which to date had not been performed by robots due to financial concerns. Manufacturers who automate tasks by combining multiple low-cost single-axis robots will find that they can replace these with T3 robots. Doing so will enable them to reduce or eliminate troublesome single-axis robot maintenance work and save money over the long run. Deploying T3 robots will enable factory owners to free up space that was taken up by a large number of robots and use their floor space more efficiently and productively.

Epson’s existing lineup of 3-kg payload industrial SCARA robots includes the G3 series, RS3 series, and LS3 series. G3 series robots have an established reputation for speed, precision, and low vibration. RS3 series robots are mounted overhead and thus use the work envelope with maximum efficiency. LS3 series robots offer high performance at a low cost. The addition of the T3 series, which offers simple setup and outstanding usability, gives Epson an even stronger lineup that meets a wider range of needs.

Key product features:

  • A built-in controller saves space and simplifies robot setup and redeployment. Epson was able to integrate all the controller components into the robot arm meaning that customers do not need a controller box.
  • A batteryless motor unit reduces maintenance and factory downtime. Factory owners do not need to exchange batteries because the T3 is able to record the back-up status of its motors by using a simple mechanical system with the latest motor technologies.
  • An end-effector I/O port and a short, stable cable conduit simplify cabling work. Epson has provided an I/O communications port closer to the end-effector. This port makes it easier to connect cables to the end-effector and supply power to it. There is no longer any need to route a long cable to the controller. The cable conduit, which contains pneumatic hoses as well as electrical cables, is shorter than in previous models. The shorter design gives it stability while the robot is moving, making it easier to route cables outside the conduit.
  • Runs on a low supply voltage (AC100V), using 30% less power than comparable Epson robot systems1. The T3 has 30% better energy performance (power consumption: 0.66 kVA) than conventional SCARA robots, therefore helping factory owners reduce long-term running costs. The T3 also runs on a single-phase alternating current at input voltages ranging from 100V to 240V, meaning that it can also be used in facilities where a large power supply is not available.

Epson’s other robots

EPSON C4 6-axis robots are the latest in the lineup of C-Series 6-axis models. With best in class cycle times, precision and motion range, EPSON C4 robots are leading the industry for compact 6-axis robot applications. EPSON C4 arms have the same unique SlimLine design as the C3 that allows the arms to reach into confined/restricted workspaces from many angles with smooth motion not achievable with competitive models. The slimline body and compact wrist of the C4 enables great motion range and less mechanical restrictions making C4 robots the most compact and flexible robots in the market today. Also with the C4, the maximum payload is now up to 4kg and we also added a 900mm model which opens more possibilities, and more applications for EPSON C4-Series Robots.

Epson G3 SCARA Robots
250 | 300 | 350

  • Best in Class Cycle Time and Precision
  • Tabletop, Ceiling and Wall Mount Models
  • Unique Curved Arm Option
  • ISO Clean & ESD Compliant Models

Epson G3 robots lead the industry with best in class cycle time, precision and motion range. With over 30 models available in sizes from 250-300mm, EPSON G3 robots are the robot of choice for high precision, high speed applications where performance AND low cost are required. G3 SCARA robots are ideal for applications such as hard drive assembly, lab automation, electronics assembly, medical device assembly, photonics, semiconductor, telecommunications, solar, and many others.

Unique to the G-Series, is the new curved arm option which allows G3 arms to be purchased as right or left curved models to maximize work envelope usage while maintaining small workspace usage overall. G3 arms are available in 250, 300 and 350mm arm lengths and come with 150mm (120 clean) Z-Axis lengths. They are also available in table top, wall or ceiling mount configurations as well as Clean/ESD configurations.
