Course Content:

\Lesson 1: Introduction to On-Device AI and Embedded Systems (Weeks 1-2)\ \Learning Objectives:\ \ \Define “On-Device AI” and explain its significance in robotics.\ \Differentiate between cloud-based and edge-based AI processing.\ \Understand the basic characteristics and constraints of embedded systems in robotics.\ \ \Key Vocabulary:\ \ \\On-Device AI:\ Artificial intelligence processing performed directly on the end device, rather than in the cloud.\ \\Edge Computing:\ Processing data closer to the source of data generation, at the “edge” of the network.\ \\Embedded System:\ A computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.\ \\Latency:\ The delay before a transfer of data begins following an instruction for its transfer. In robotics, it refers to the delay between sensing and acting.\ \\Bandwidth:\ The maximum rate of data transfer across a given path. Limited bandwidth can hinder cloud-based AI.\ \ \Content:\ \The field of robotics is rapidly evolving, driven by advancements in artificial intelligence. While powerful AI models often run on large, cloud-based servers, there’s a growing need for robots to perform intelligent tasks autonomously and in real-time, even when disconnected from the internet or with limited network bandwidth. This is where “On-Device AI,” also known as “Edge AI,” becomes crucial.\

On-Device AI refers to the execution of AI algorithms directly on the robotic platform itself. Instead of sending sensor data to a remote server for processing and then receiving commands back, the robot processes information and makes decisions locally. This paradigm shift offers significant advantages: reduced latency, enhanced privacy, improved reliability in environments with intermittent connectivity, and often lower operational costs. Consider a robot navigating a cluttered warehouse. If it relies on cloud AI for obstacle detection, even a slight network delay could lead to a collision. With on-device AI, decisions are made instantaneously, leading to safer and more efficient operation.

Embedded systems are the backbone of most robotic platforms. These are specialized computer systems designed to perform a specific function within a larger system. Unlike general-purpose computers, embedded systems are typically characterized by limited processing power, memory, and energy resources. These constraints pose unique challenges for implementing complex AI models, which often demand substantial computational resources. Therefore, optimizing AI models for efficient execution on these constrained embedded platforms is a central theme of this course. We will explore how to make AI models “lean” and efficient without sacrificing too much accuracy.

\Hands-on Example:\ \To begin, let’s explore the concept of system resources on your own machine.\ \ \Open a terminal or command prompt.\ \For Linux/macOS, use the command \htop\ (you might need to install it with \sudo apt-get install htop\ or \brew install htop\). For Windows, open Task Manager (Ctrl+Shift+Esc).\ \Observe the CPU and memory usage as you run different applications. Notice how much resources a web browser or a video player consumes.\ \Reflect on how these resource limitations would impact a small robot with a battery and a less powerful processor. This exercise helps to visualize the “constrained environment” we’ll be working within for on-device AI.\ \

\Lesson 2: Fundamentals of Machine Learning for Robotics (Week 3)\ \Learning Objectives:\ \ \Distinguish between supervised, unsupervised, and reinforcement learning.\ \Understand common machine learning algorithms relevant to robotics, such as regression and classification.\ \Identify typical applications of machine learning in robotic systems.\ \ \Key Vocabulary:\ \ \\Machine Learning (ML):\ A subset of AI that enables systems to learn from data without being explicitly programmed.\ \\Supervised Learning:\ Training a model on labeled data, where the desired output is known.\ \\Unsupervised Learning:\ Training a model on unlabeled data to find patterns or structures within the data.\ \\Reinforcement Learning (RL):\ Training an agent to make decisions by maximizing a reward signal in an environment.\ \\Regression:\ A supervised learning task that predicts a continuous output value.\ \\Classification:\ A supervised learning task that categorizes data into discrete classes.\ \ \Content:\ \Machine Learning (ML) forms the bedrock of many AI applications, including those in robotics. At its core, ML allows computer systems to learn from data, identifying patterns and making predictions or decisions without explicit programming for every possible scenario. This learning process is often categorized into three main types: supervised, unsupervised, and reinforcement learning.\

Supervised learning is perhaps the most common type and involves training a model on a dataset where each input is paired with a corresponding correct output, or “label.” For example, in a robotic vision system, you might train a model to identify specific objects by providing it with thousands of images of those objects, each labeled with the object’s name. Once trained, the model can then predict the label for new, unseen images. Within supervised learning, two prominent tasks are regression and classification. Regression aims to predict a continuous numerical value, such as a robot’s estimated distance to an obstacle or the optimal torque for a motor. Classification, on the other hand, deals with predicting a discrete category or class, like identifying whether an object is a “cup,” “bottle,” or “box,” or classifying a sensor reading as “safe” or “unsafe.”

Unsupervised learning differs in that it works with unlabeled data. The goal here is for the
