Autonomous Dual-arm Robot
Harness the power of Epson's robotics technologies
In November 2017, Epson announced the commercialization of a "seeing, sensing, thinking, working" autonomous dual-arm robot named the WorkSense W-01. This robot harnesses the power of the full range of Epson's robotics technologies.
In recent years, manufacturers' needs have grown more diverse with demand for products fluctuating sharply and a growing necessity to flexibly accommodate small-lot production and just-in-time (JIT) production. Industrial robots are conventionally installed in a fixed location on a line to perform a given task. The WorkSense W-01, however, was developed for easy mobility so that it can be wheeled from place to place to perform assembly, transport, and other tasks. The features described below enable the robot to automate production tasks that previously defied automation.

The robot is equipped with four head-unit cameras and two arm-mounted cameras that give the robot human-like vision, enabling it to accurately detect an object's position and orientation in three-dimensional space. And even if the location of objects and obstacles changes, the robot is able to independently "see" and determine their position.
The robot arms are outfitted with Epson's highly sensitive, precision force sensors, which are already available on sale. The robot is thus able to perform delicate assembly, transport, and other tasks that require human-like force control to avoid damaging objects.
Multipurpose hands that can grasp, grip, and clamp objects of various shapes and sizes are included as standard end-of-arm tooling. They can manipulate tools and jigs that were designed for humans.
The robot is able to accurately detect the position and orientation of objects in three-dimensional space, so even if the robot is relocated, it can immediately start work with no programming change required. This gives the robot the ability to flexibly adapt to sudden changes in production. So, for example, it can be wheeled to different locations to perform different tasks every day, if need be. The robot independently decides the path and orientation of its 7-axis arms and is able to avoid obstacles.
The robot's two 7-axis arms move like human arms. The dual arms move independently from one another to allow the robot to perform tasks that a single-arm robot cannot, such as tightening a screw in a component with one arm while holding the component in place with the other.
Epson aims to hone its original robotics technologies with the aim of freeing people from menial work to enable them to concentrate on more creative tasks, and of helping to realize a world in which humans and robots coexist.
