With the advancement of Physical AI, robots are evolving to perceive their surroundings, understand situations, and autonomously perform increasingly complex physical tasks.
Achieving this level of intelligence requires large-scale AI models and high-performance computing resources.
However, processing all AI workloads onboard a robot requires high-performance GPUs, increasing hardware costs, power consumption, heat generation, and overall weight while reducing battery life. Higher power consumption means heavier batteries, shorter operating times, and higher robot costs.
One approach to overcoming these limitations is AI Inference Offloading.
This approach moves computationally intensive AI inference tasks, such as robot motion planning and prediction, which would otherwise run onboard the robot, to external computing infrastructure.
Rather than relying solely on its own computing resources, a robot can leverage powerful GPUs deployed at the mobile network operator's Edge (AI-RAN) to run more sophisticated AI models.
In this architecture, low-latency, high-capacity wireless connectivity is essential to carry video streams from the robot to the network Edge (uplink) and robot control commands from the Edge back to the robot (downlink). This makes 5G connectivity a key requirement.
A demonstration of this approach was presented at NVIDIA GTC Berlin 2026 through a collaboration between Deutsche Telekom, Nokia, NVIDIA, and Agile Robots [NVIDIA] [Agile Robots].
Using a Franka Research 3 dual-arm robot (shown below), the companies demonstrated a cooling fan insertion task, one of the steps involved in server assembly.
The demonstration showcased an architecture in which AI workloads are distributed between the robot's onboard computing resources and GPUs at the mobile network operator's Edge.
This demonstration is significant because it illustrates how mobile network operators could expand their role beyond traditional data transport and 5G connectivity services to become providers of distributed AI computing infrastructure that supports AI inference for industrial robots.

AI Inference Offloading does not mean that robots lose their own intelligence.
Instead, AI capabilities are distributed across multiple locations, including the robot itself.
The demonstration presented by NVIDIA and Agile Robots at GTC Berlin divides robot AI processing into three layers.
The key question is where each workload runs.
Reflexive actions remain onboard the robot. Safety functions and motion control respond immediately without waiting for network communication.
Computationally intensive workloads, such as motion planning and prediction, are offloaded to GPUs at the mobile network operator's Edge, while model training continues in large-scale AI factories (Central Cloud).
| AI Layer | AI Functions | Timing Requirements |
|---|---|---|
|
On-Device AI (Onboard the Robot) |
Reflexive actions: Balance maintenance, real-time environmental perception, and immediate action execution (e.g., collision avoidance and emergency stops). The robot must remain safe and operational using its own computing resources, even if network connectivity is lost.
|
Millisecond-level response |
|
Network Edge (AI-RAN) |
AI inference: Robot motion planning and prediction. Computationally intensive tasks, such as motion planning and prediction, are offloaded to powerful GPUs located near the robot.
To respond quickly, the GPUs must be geographically close to the robot, and the wireless connection must provide low latency and high capacity.
This enables the robot to leverage computing resources beyond the hardware capabilities of its onboard system.

Extended Robot Battery Life:
High-performance GPUs consume considerable power. By offloading AI inference to the mobile network operator's Edge, the computing hardware requirements onboard the robot can be reduced, allowing more of its battery power to be used for mobility and actual physical tasks.
Although conducted independently of the four-company PoC, an experiment published by Microsoft Research in September 2026, Offloaded Inference for Real World Physical AI Robotics, provides an interesting reference.
In its Stretch-3 experiment, Microsoft reported that AI inference offloading increased robot battery runtime by more than 100% under the tested configuration.
Improved AI Processing Performance:
According to Microsoft Research, when using a relatively low-performance onboard GPU, motion planning workloads can take up to 383% longer to process compared with an NVIDIA A100 data center GPU.
The study also reports that the accuracy of Vision-Language-Action (VLA) models can decrease by approximately 50% under constrained onboard computing conditions.
Therefore, offloading AI inference workloads to the mobile network operator's Edge, equipped with high-performance GPUs, enables robots to leverage more sophisticated AI models.
Reduced Robot Hardware Costs:
With AI inference offloading, expensive GPUs do not need to be installed in every robot. Instead of equipping each robot with its own high-performance GPU, multiple robots can share GPU resources deployed at the mobile network operator's Edge through the 5G network.
This reduces robot hardware costs. Furthermore, when AI models need to be upgraded, the models can be updated at the network Edge without replacing the hardware in each individual robot.
As robots increasingly rely on the mobile network operator's Edge (AI-RAN) for more sophisticated reasoning, 5G networks will evolve beyond conventional mobile connectivity to become a critical infrastructure underpinning the success of industrial robot AX (AI Transformation) and Physical AI.
