Let’s Talk Technical: Edge AI Part 2, From Smart Devices to Physical AI

Topic Questions

Why do you think Edge AI has grown so much over the past 5 years?

  • Edge AI has grown because devices are generating more data, and companies increasingly need to turn that data into useful intelligence. At the same time, hardware and AI models have become smaller, faster, and more efficient, making AI practical on edge devices. Processing data locally also reduces latency, bandwidth, cloud costs, and security concerns. Overall, it’s the combination of greater demand for smarter devices, improved technology, and the benefits of local processing.

What are some examples of smart devices that consumers may have at home?

  • Examples of smart home devices include smart thermostats such as Ecobee, smart refrigerators, smart doorbells, and security cameras.

  • AI can make these devices more useful by recognizing specific activity and reducing unnecessary alerts. For example, a smart doorbell can distinguish between people, vehicles, and animals, providing notifications only when relevant. Adoption of these technologies can also vary by region and culture.

What are the right metrics for developers to be looking for?

  • Developers should evaluate edge AI platforms across performance and power efficiency, cost, software/developer experience, reliability and supply longevity, and vendor support. While TOPS is an important measure of AI capability, the best platform is one that can move efficiently from prototype to a cost-effective, reliable, and supportable production product.

What constraints are you seeing as bottlenecks for Edge AI deployment?

  • The main bottlenecks for Edge AI deployment are engineering adoption, uncertainty around AI, and market fragmentation. Traditional embedded engineers may still be hesitant or unfamiliar with incorporating AI into their systems, while the broad and sometimes overwhelming scope of AI can lead some companies to delay or pause adoption.

  • In addition, the rapid proliferation of AI tools and diverse hardware architectures has created fragmentation, making it difficult for companies to determine which technologies and approaches to adopt. As engineers gain experience and the market matures, organizations will need time to navigate these options and identify the right path forward.

What applications are the most demanding for Edge AI?

  • The most demanding Edge AI applications are those that require real-time processing of sensor, perception, and generative AI data directly on devices, often in high-volume or high-stakes environments. Key examples include arc-fault detection, vibration and other time-series sensor analysis, computer vision such as license-plate detection, and audio processing. These applications can span industries from agriculture and industrial systems to military communications and consumer products.

  • An emerging and potentially much larger area is multimodal Edge AI, which combines sensors, vision, audio, and generative AI/LLMs to interact with the physical world. For example, Edge AI can enable hands-free, contactless control of anesthesia machines, where reliability, low latency, privacy, and continuous operation are critical. Overall, the most demanding applications are moving toward systems that combine perception, real-time decision-making, and human interaction at the edge, particularly in environments where cloud connectivity is impractical or where latency and reliability are essential.

What is Physical AI and how is it different from traditional Edge AI?

  • Physical AI refers to AI systems that can not only perceive and interpret the physical world but also take action within it. Traditional Edge AI has primarily focused on perception, such as analyzing sensor data for anomalies or using computer vision to identify people or objects, with humans or other systems ultimately responsible for responding. Physical AI adds the ability to act through actuators such as robotic arms, motors, or autonomous vehicles - for example, a rover understanding a command and physically moving an object.

  • The key distinction is that Physical AI moves from “seeing and informing” to “seeing, reasoning, and acting.” Because these systems must operate autonomously and safely in the real world, they generally require significantly more computation and more sophisticated safety controls. Examples include humanoid robots, autonomous mobile robots, robotic manipulators, and self-driving vehicles.
