- ESP32‑S3 MCU with dual‑core Xtensa and vector extensions for efficient AI.
- On‑device speech recognition — no internet, no cloud.
- Optimized firmware: AI Teacher is preinstalled in RoboControl, menu‑selectable.
- Low‑power, portable: designed for classrooms, competitions, and at‑home use.
Learning sticks when it’s visual, verbal, and immediate. AI Teacheris a built‑in app in the GRC RoboControl firmware that makes beginners practice English vocabulary, numbers, everyday objects, and simple arithmetic in a playful, guided way. As images appear on screen (e.g., cup, tree, book), the learner says the word, and the device checks the answer on‑device. If it’s wrong, AI Teacher offers another try and then clearly pronounces the correct word — reinforcing the right response.
It’s designed for classrooms, clubs, and home use: quick to start, easy to understand, and motivating through instant feedback — with hint and skip options when needed.
Built‑in & free: AI Teacher ships preinstalled with RoboControl. Just switch to it from the main menu.
Things Used- Hardware: GRC AI RoboControl (ESP32‑S3)
- Optional: CrowBot (for robotics demos), CrowPanel (for scoreboards & contests)
- Software: AI Teacher(preinstalled in RoboControl firmware)
Nothing to download: the app is already in the firmware and ready to launch from the menu.
Features & Why it Works· Visual + verbal learning: see an image → say the word — proven combination for retention.
- Dynamic challenges: identify objects/animals; answer simple math (e.g., 3 + 5 → “eight”); recognize everyday sounds.
- Instant feedback: speech recognition evaluates responses, encourages retries, then speaks the correct answer.
- Support while learning: hint and skip buttons; limited retries to balance challenge and confidence.
- On‑device processing: responses are checked on the device (no cloud dependency).
- Menu‑integrated: AI Teacher is a selectable mode in RoboControl.
AI Teacher focuses on beginner‑friendly content:
- Alphabet & Numbers: A–Z; 0–20
- Animals: e.g., cat, dog, bird, fish, elephant, penguin, tiger, panda
- Objects & Nature: e.g., cup, ball, car, camera, bread; tree, sun, rain, snow, star
- Human & Body: e.g., boy, girl, man, woman; head, eyes, mouth, hand
- Verbs (actions): e.g., run, jump, sit, stand, drive, push, pull, throw
- Home & School: e.g., house, table, chair, phone, key; book, bag, pen, desk, ruler
- Shapes & Math: circle, square, plus, minus (with simple arithmetic practice)
- Everyday sounds: dog, cat, bird, car, phone
The content set is curated for early learners and mixed skills: vocabulary, listening, and number sense.
How to Use1. Power on your RoboControl board.
2. From the main menu, select AI Teacher.
3. Follow on‑screen prompts: speak the word for the shown image, identify a sound, or answer a simple math problem.
4. Use Hint or Skip when needed; the device provides instant feedback and pronounces the correct answer.
Tip for teachers: pair RoboControl with a classroom display or camera view so everyone sees the prompts.
Use CasesEducation- Integrate short AI Teacher sessions into English or STEM lessons to combine speech practice with technology.
- Rotate students in pairs/teams; each correct answer advances the round and keeps engagement high.
Works entirely on‑device, so it’s reliable for classrooms and workshops.
- Combine with CrowPanel Game Interface for AI Learning to run time‑trial contests on pronunciation speed and accuracy.
Maintain a leaderboard on CrowPanel; run heats, semifinals, and finals in a single session.
- Turn RoboControl into a compact learning station for early vocabulary and numbers.
- Parents and makers can extend sessions with robotics demos using CrowBot.
- Classroom ideas: Share your lesson plans or group formats that worked well with AI Teacher.
- Challenge formats: Post your pronunciation race rules or scoring methods (especially with CrowPanel).
- Feature requests: Tell us which topics, sounds, or difficulty levels you’d like next. Popular requests go on our roadmap; some will land in upcoming firmware updates.
AI Teacher comes preinstalled and free with GRC AI RoboControl. Launch it from the menu and start practicing immediately — no extra steps, no internet required.
