Industrial automation


The EPSON Scara LS-Series is designed for price sensitive robotic applications. The price of the LS robot starts at 10.000 EUR, which includes the LS robot, the RC90 robot controller and the EPSON RC+ robot programming environment as well.

And with this economic price, the LS-Series still offers excellent performance, precision and reliability, as you are used to from EPSON. The LS is ideal for assembly, pick-and-place, loading/unloading, feeding type jobs, and can be ordered in standard or cleanroom (ISO4) configurations.

Simple to understand programming language: SPEL+

EPSON robot programming is done in a Windows-based programming environment called EPSON RC+. The programming language itself is called SPEL+.
SPEL+ is very similar to BASIC. It is quick to learn and easy to understand. After programming and compiling in EPSON RC+, the program is transferred to the robot controller. From that point, the controller controlls the robot (without the need of the PC).

Do you need to control other devices as well? No problem. SPEL+ can do a lot more than just robot control. It is a multitasking language, capable of controlling task parallel or independent of the robot.

Complex motion control

SPEL+ includes a wide range ot motion commands: PTP (point-to-point motion), linear motion, CP (continuous path motion), etc. or special motion commands such as Jump or Palletizing commands.

Robot Simulator, to plan ahead

With the use of the 3D robot simulator, you can plan ahead, design and simulate your application before your robot even arrives. Inside EPSON RC+ you can add 3D models to model your robotic cell, and check the cycle times. You can run study and verify your concept ideal before having to manufacture anything.

Camera Systems

EPSON's integrated vision systems

You can choose form a wide range of camera systems offered by the automation industry. But EPSON also provides its own solution. EPSON's vision systems are integrated with the robot's software, making it easy to connect and to access all the parameters and results of the camera system.

CV1, Compact Vision

The CV1 (Compact Vision) controller connects to the robot controller via Ethernet. Programming is done from inside EPSON RC+.
The CV1 supports up to 2 x EPSON USB cameras (VGA, 1.3MP or 5MP).

CV2, Compact Vision

The CV2 connect to the robot controller via Ethernet connection. The CV2 offers quicker processing and supports high speed GigE cameras for faster data transfers. Programming is done inside EPSON RC+. The CV2 supports up to 4 x GigE cameras and up to 2 x USB cameras at the same time.

PV1, PC Vision (for RC700 only)

The EPSON PV1 is a customizable option. It is installed on a Windows PC, that connects to the robot controller. The processing speed is the function of the hardware used. The PV1 support up to 8 x EPSON GigE cameras which are available in different color modes or resolutions.
