Hot stuff in forging: Toyota collaborates with READY Robotics to introduce sim-to-real robotic programming in industrial manufacturing

Simulated in NVIDIA Omniverse and Controlled by READY Robotics ForgeOS.

 

 

READY Robotics, a pioneer in operating systems for automation and robotics, is collaborating with Toyota Motor Corp. and NVIDIA to bring a significant leap forward in industrial robotics. Toyota will employ READY ForgeOS in tandem with NVIDIA Isaac Sim, a robotics simulator developed on NVIDIA Omniverse, to build a state-of-the-art simulated robotic programming environment for its aluminum hot forging production lines.

The collaboration is set to enhance safety and efficiency in Toyota's manufacturing processes. Typically, programming robotic systems for forging necessitates that the metal parts remain hot during programming, presenting significant safety challenges. By integrating NVIDIA Isaac Sim -- an extensible application developed on the Omniverse platform for simulating, developing, and testing robots -- with ForgeOS, programming can now be accomplished seamlessly in a simulated environment, eliminating the risks associated with hot parts.

READY Robotics is the developer of ForgeOS, an industrial OS for robots and automation, and a pioneer in time-saving automation solutions that overcomes the obstacles faced by manufacturers. ForgeOS simplifies the programming process, reducing the typical complexities of robotic systems and enabling an easy-to-use experience for any industrial robotic manipulator.

READY has integrated ForgeOS with NVIDIA Isaac Sim to provide best-in-class visual and physics-simulation fidelity, bringing unprecedented realism to robotic simulations. With ForgeOS' intuitive programming and NVIDIA's realistic simulation environments, Toyota can quickly program and optimize complex robotic hot forging routines in simulations that capture the nuance of the complex hot forging processes.

Once proven in the simulated environment, these programs can be transferred into the live production work cell seamlessly, removing the necessity for programming in the physical installation itself, thereby reducing the concern for safety around hot parts. Since ForgeOS controls both the simulation and physical work cell, the program can be transferred and updated in seconds, minimizing downtime and making the work cell easier to maintain.

Another novel aspect of this "sim-to-real" workflow is ForgeOS' ability to relay real-time production data from the cell on the factory floor back to the original NVIDIA Isaac Sim simulation. This forms a digital twin of the live cell, enabling visualizations of its current state and facilitating greater monitoring and oversight.
