Students in Stanford's robotics class build AI-powered dog robots called Pupper and teach them skills like fetching and firefighting.
Present simple for general facts and explanations — used throughout to describe how the class works and what robots do: "Pupper looks so cute," "The platform that we use is called Pupper," "You need to be able to see the world." This is the default tense for technical explanations.
Relative clauses with "that" for adding detail — helps pack information efficiently: "The platform that we use is called Pupper," "There's one team that put an arm on the top of the Pupper." Common in academic speech.
Modal verbs "can" for capability and potential — appears frequently to emphasize what the robot and students are able to do: "It can navigate pretty well," "Pupper can actually fetch things," "you can think of a Pupper being a companion robot."
This video showcases Stanford's CS123, an introduction-level robotics class where undergrads build quadruped robots from scratch in just four weeks. The core platform is Pupper, a cute, dog-like robot that students can customize in creative ways—one team added an arm for fetching, another built a water jet to turn it into a "firefighter." After the initial build phase, students go beyond mechanics and into intelligent programming: they learn kinematics, reinforcement learning, and even large language models to make Pupper interact intelligently with the world. The instructor emphasizes the hands-on, experiential nature of the course, where students get to do live demonstrations in front of notable roboticists from Google DeepMind and NVIDIA.
For shadowing, this is an excellent choice. The instructor speaks at a measured, conversational pace with clear pronunciation, and the vocabulary mixes accessible explanations with technical terms presented naturally—"quadruped," "reinforcement learning," "locomotion"—giving learners exposure to both everyday and specialized English. The tone is encouraging and informal, making it engaging to repeat.
This suits high-beginner to lower-intermediate learners (B1 level). While some robotics terminology is specialized, the overall sentence structures are straightforward, and the context is concrete and visual. Shadowing this material helps learners internalize fluent academic English, pick up tech vocabulary in context, and hear how native speakers explain complex concepts simply.
from scratch — starting from the beginning with no existing foundation; building something completely new. "Most students can build Pupper from scratch from parts within the first four weeks."
hands-on — involving direct practical experience and activity rather than theory alone. "This is a very hands-on class."
get to experience — to have the opportunity to experience something (often something valuable or challenging). "They get to experience the challenges of doing live demo in front of a big crowd."
the Bay area — the region around San Francisco Bay in California; used here as a shorthand for a hub of tech innovation. "We invite a lot roboticists, famous roboticists in the Bay area. Like, from Google DeepMind, from NVIDIA."
this is just the beginning — this is an early stage; there is much more to come. "There are plenty of opportunities to advance in robotics, and this is just the beginning."
