Realistic physics-based digital twin environment [Physics Simulation]
AGX Dynamics
A physics engine library that enables the construction of digital twins to predict the future! Incorporating real physics into virtual spaces expands possibilities!
The use of digital twins is expanding across various industries and applications. Generally, a "digital twin" sends information sensed from the physical world to a virtual space model via communication technologies like 5G, allowing the virtual model to operate almost simultaneously with the real physical model. This operational data is then utilized for predictive maintenance and other applications by combining it with simulation technologies and AI. In addition to the general concept of "digital twins" mentioned above, our company provides development tools and technical consulting aimed at recreating real physical laws in virtual space, striving for behavior that matches the physical world. In particular, we support the realization of truly usable digital twin environments targeted at manufacturing sites, civil engineering construction sites, offshore environments, disaster sites, and other settings.

basic information
★Differences from General Digital Twins★ ● Objects (models) in the virtual space possess not only visual models but also physical models, having physical properties such as shape, mass, and inertia. ● The models in the virtual space are composed of physical models and virtual models, using the physical model for physical calculations, while the visual model moves in accordance with the physical model. ● The virtual model does not operate based on communicated past operation history information; instead, it moves in accordance with the physical model that operates under the recreated physical laws within the virtual space. ● This allows for simulations in the virtual space, even for configurations of manufacturing lines or placements of robots where there is no past data, enabling the realization of a digital twin that predicts the future. ★Key Technologies★ ● [Accuracy and Performance of Physical Calculations] Physical calculation libraries (physics engines) ● [Graphics Performance] Simulation development environments ★Application Areas★ ● Factories, manufacturing and production facilities ● Civil engineering construction sites ● Areas that are difficult to access, such as space, deep sea, and disaster sites

We are conducting simulations of rigid body grasping by robots. Generally, it is difficult to maintain stable simulations in grasping states, but it is possible to handle them stably by optimizing the constraints. Additionally, various parameters can be obtained within the simulation, such as the reaction forces at contact points and the torques of each robot axis, making it a promising application for use in teaching-less systems and in conjunction with artificial intelligence.

This is a cable simulation. AGX Dynamics handles rigid body constraint simulations, so it cannot fundamentally deal with flexible materials. In this cable simulation, the cable is represented by connecting many small rigid bodies with constraints, and by setting parameters for damping and elasticity in those constraints, we can reproduce the behavior of the cable we want to simulate. Additionally, this simulation has constraints with six degrees of freedom, allowing it to account for both movement and rotation. Therefore, it is possible to reproduce twisting phenomena as well. The advantage of AGX Dynamics' physics engine lies in the fact that connecting rigid bodies continuously with constraints that have six degrees of freedom does not lead to simulation divergence, and this is a point where the direct method solver is technically superior. This advantage is not only applicable to cables but also demonstrates superiority in accuracy and performance in simulations of mechanisms where each rigid body is stiffly connected, such as industrial robots and construction machinery.

Company information
We provide technical consulting and contract development related to the construction of physical simulations. In collaboration with Algoryx Simulation AB in Sweden, we offer technical consulting for customers who wish to implement the professional-use physics engine "AGX Dynamics" into user applications and build custom simulators. Building a physical simulation environment requires a wide range of knowledge, including system planning, modeling, system identification, and modeling techniques, as well as physics, engineering, and mathematics. Additionally, various tools such as 3D CAD, programming languages like Python and C++, game engines, and control software like Matlab/Simulink may be needed for usage and integration. Our technical support team, which can provide these technologies in a one-stop manner, is our strength and characteristic.
