The Fraunhofer Institute in Germany conducts practical research in a number of important fields, including AI, cybersecurity, and medicine. One of its 76 research institutes, the Fraunhofer IML group, seeks to advance robotics and logistics. The researchers are testing the simulation capabilities of NVIDIA Isaac Sim to potentially enhance the design of robots. 

Its most recent mobile robot development, O3dyn, uses technologies developed by NVIDIA for simulation and robotics to produce an indoor-outdoor autonomous mobile robot (AMR).

“We’re looking at how we can go as fast and as safely as possible in logistics scenarios,” said Julian Eber, a robotics and AI researcher at Fraunhofer IML.

The latest research aims to bridge the sim-to-real gap by developing and validating these AMRs in simulation. The researchers use Isaac Sim to train the AMR virtually by placing it in photorealistic, physically correct 3D environments.

The team leverages Isaac SIM to test the operation of O3dyn by importing a complete 3D CAD model of the robot into the simulated environment. The accurate specifications are combined with Omniverse PhysX to deliver a realistic response to any input. The robot uses simulated warehouse environments to train the AI guidance on how to navigate and operate in its intended missions.

In the physical world, O3dyn uses a variety of camera and sensor inputs into the NVIDIA Jetson edge AI and robotics platform to aid with navigation. With improved speed and agility, it can move at up to 13.4 m/s (30 mph) and has omnidirectional wheels that can move in any direction.

“The omnidirectional dynamics is very unique, and there’s nothing like this that we know of in the market,” said Sören Kerner, head of AI and autonomous systems at Fraunhofer IML.

As a result, the virtual robot can move as quickly in a simulation as the actual robot can in the physical world. Harnessing the virtual environment allows Fraunhofer to accelerate development, safely increase accuracy for real-world deployment and scale up faster.

Fraunhofer refers to this idea as simulation-based AI. Fraunhofer is making the AMR simulation model open source so that developers can enhance it in order to achieve results more quickly.

Chipotle testing avocado processing robot in test kitchen

Chipotle Mexican Grill announced Autocado, an avocado processing cobotic prototype that cuts, cores, and peels avocados before they are hand mashed to create the restaurant’s famous guacamole. The prototype, developed in collaboration with Vebu , is currently being tested at the Chipotle Cultivate Center in Irvine , California.  How Autocado works  A team member loads Autocado with a full case of ripe avocados and selects the size setting. Autocado can hold up to 25 lbs. of avocados at once. One at a time, avocados are vertically oriented, then transferred to the processing device. The avocados are sliced in half. Their cores and skin are automatically removed, and the waste is discarded.  The fruit is safely collected in a stainless-steel bowl at the bottom of the device.  A team member removes the bowl of avocado fruit and moves it to the counter where they add additional ingredients and hand mash the avocados to make Chipotle’s signature guacamole.  How the Autocado idea s

Intrinsic tested its latest platform and Flowstate with Comau , an Italian-based robot manufacturer and global systems integrator. Comau has been working with Intrinsic for several years now to validate Intrinsic’s platform technology and developer product, Flowstate, through real-world use cases.  Flowstate, announced earlier this year in May , is a robotic software development platform. It’s Intrinsic’s first developer product built on the Intrinsic platform. Comau was also introduced as the company’s first industry partner in May.  The Intrinsic Flowstate software  adds a layer of abstraction to traditional robotic software tools with the goal of reducing the development skillset required while making it easier than ever before to program a robot in simulation. “Partnering with Comau over the years has brought our team a tremendous amount of expertise, knowledge, and real-world use cases to focus our efforts on. We’re excited for what’s next and what it will mean to the solutio
