Cozmo and Vector aren't just desk companions — they're Python learning platforms with camera vision, face recognition, and motor control APIs. If you own one, you're sitting on one of the best coding robots ever made. Digital Dream Labs maintains the Cozmo 2.0 SDK; the Vector SDK is community-maintained. Both use Python 3 with access to cameras, motors, sensors, and animations. Here you'll learn SDK setup, 5 progressive Python projects, and how to build custom autonomous behaviors.

SDK Overview — Cozmo vs Vector
Cozmo SDK (cozmo package)
Original Anki SDK maintained by DDL. Connects via phone app (WiFi). Access: camera (VGA), motors, lift, head, cube interaction, face recognition, animation triggers. Cozmo 2.0 works with the same SDK.
- AI-Powered & Fully Autonomous: Vector navigates, recognizes faces, and reacts to his surroundings with lifelike independence — no remote control required.
- Now Connected to ChatGPT: Experience a new level of conversation with more natural, intelligent, and meaningful interactions. Powered by ChatGPT, Vector can answer complex questions, engage in richer conversations, and provide more insightful responses. 𝗥𝗲𝗾𝘂𝗶𝗿𝗲𝘀 𝗮𝗻 𝗮𝗰𝘁𝗶𝘃𝗲 𝗖𝗵𝗮𝘁𝗚𝗣𝗧 𝘀𝘂𝗯𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻 (𝗮𝗽𝗽 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗹𝗲 𝗼𝗻 𝘁𝗵𝗲 𝗔𝗽𝗽 𝗦𝘁𝗼𝗿𝗲).
- Multilingual Support: Vector can now understand multiple languages, making him the perfect smart companion for global households and language learners. Vector can now understand Spanish, French, German, Chinese and more! Say “Hey Vector.”
- Smart Camera & Sensors: Built with an HD camera and advanced sensors for real-time mapping, facial recognition, and obstacle detection.
- Expressive Personality: Watch Vector come to life with animated eyes, emotions, and playful reactions that evolve as you interact with him.
Vector SDK (anki_vector package)
Direct WiFi (no phone). Access: camera (HD), motors, screen, audio, face recognition, navigation, cloud AI. Authentication required (DDL account).

Which SDK Should You Use?
Cozmo 2.0: use cozmo SDK. Vector: use anki_vector. APIs are similar but not identical — code doesn't transfer 1:1.
Setting Up Your Development Environment
Python 3.9+ required. pip install cozmo or pip install anki_vector. Use a virtual environment. Cozmo: phone as WiFi bridge, enable SDK mode in app. Vector: direct WiFi, python -m anki_vector.configure. First test: script that says “Hello World” and plays an animation.
Project 1 — Drive, Speak, and Animate (Beginner)
drive_straight(), turn_in_place(), set_head_angle(), set_lift_height(). say_text(), play_anim(), play_anim_trigger(). Build a “morning routine”: wake animation, greeting, drive to position, celebrate.
Project 2 — Cube Interaction Game (Intermediate)
Cube tap events, light patterns, dock_with_cube(). Build a “Simon Says” game: flash cube lights, detect taps, score keeping. Teaches event-driven programming.
Project 3 — Face Recognition and Personalized Responses (Intermediate)
enable_facial_expression_estimation(), face events, named faces. “Greet by Name”: turn to face, identify, personalized greeting. Different reactions for known vs unknown faces.
Project 4 — Camera Feed and Basic Computer Vision (Advanced)
get_latest_image(), save frames, stream. Integrate OpenCV: color detection — robot follows a colored object. Pipeline: image processing, HSV masking, contour detection.
Project 5 — Custom Autonomous Behavior (Advanced)
Combine camera, cube detection, face recognition with decision logic. “Room Patrol”: drive around, look for faces, greet recognized people, investigate cubes, avoid edges. Python async/await for concurrent behaviors — drive and watch for faces simultaneously.
Troubleshooting Common SDK Issues
Connection: WiFi bridge, authentication, firewall. SDK version compatibility. Robot not responding: battery, sleep mode, SDK mode. Camera latency: frame rate optimization. Help: GitHub issues, r/cozmo, Hackster Cozmo projects, r/cozmo.
FAQ
Can I still use the Cozmo SDK in 2026?
Yes — DDL maintains it. Works with original Cozmo and Cozmo 2.0.
Is the Vector SDK still working?
Community-maintained; works with quirks. DDL cloud required for some features.
What Python level do I need?
Basic: variables, functions, loops, if/else. Intermediate helps for Projects 3–5.
SDK without the phone app?
Cozmo: no — app is WiFi bridge. Vector: yes — direct WiFi.
Does Cozmo 2.0 have a better SDK?
Same SDK; 2.0 has better hardware, battery, speaker, self-docking.
Can I make Cozmo do things the app can't?
Yes — raw camera, custom animations, programmatic motor control, behaviors the app doesn't expose.
Useful for learning Python professionally?
Yes — event-driven code, async/await, APIs, image processing, OOP.
SDK on Windows, Mac, Linux?
Yes — all three supported.
What if I make a mistake in code?
Nothing permanent — restart the robot. You can't brick it via SDK.
Can I share custom behaviors?
Yes — Python scripts are shareable. Community posts on GitHub, Instructables, Reddit.
Conclusion
Five projects from basic drive commands to autonomous room patrol. Cozmo and Vector SDKs turn companion robots into legitimate Python learning platforms. For more Python robotics see Raspberry Pi robot projects. Choosing a language? Read robot programming languages.
