A quadruped robot dog that fits in one hand, walks on eight coreless servos, sees the world through an ESP32-S3 AI vision module, and switches between Arduino, Python and Scratch on demand. Aluminium body. LEGO-compatible. Boston-Dynamics-inspired, classroom-approachable.
You don’t need a ₹30-lakh Unitree Go2 to teach a student how a quadruped walks, sees and reacts. MechDog packs the same inverse-kinematics dynamics, AI-vision loop and multi-language programming into a palm-sized aluminium chassis your school — or your desk — can actually afford.

Four legs, two joints per leg, all driven by high-speed hollow-cup coreless servos on metal-linkage limbs. The body is machined aluminium alloy — sturdy enough to survive a workshop, light enough for a Class-8 student to carry in one hand.

The in-house IK algorithm gives you real-time control over pitch, roll, height and stride — the same primitives Boston Dynamics exposes on Spot. An IMU sensor keeps posture stable on tilted or bumpy terrain. Visual PC editor lets students design gaits by dragging endpoint coordinates.

The Advanced Kit adds an ESP32-S3 co-processor with a 2 MP camera — running colour recognition, CNN face detection, colour tracking and visual line following on-device. Video streams to any browser via a URL — no app to install, no cloud round-trip. AP hotspot and STA LAN modes both supported.

Beginners drag Scratch blocks in the Wonderbot app — 16 preset actions to start. Middle-schoolers write MicroPython. Advanced students go to Arduino C/C++ for full firmware control. The same robot supports all three via a firmware switch — so a school buys once, then grows the syllabus with the student.
Body, structure, dynamics and expansion — five product-photography views.
Mechanical, electrical, sensor, software — everything the Advanced Kit ships with.
Specs per manufacturer datasheet. The Advanced Kit adds the ESP32-S3 AI vision module, touch sensor, light sensor, dot-matrix and MP3 module vs the Standard Kit. Institution discount, GeM listing, KYC and bulk pricing on enquiry.
Same robot, three languages, six stages — MechDog scales from “never coded before” to “custom IK on ESP32 firmware” without buying a second platform.

The palm-sized quadruped Indian schools, coding clubs and hobbyists reach for when they want a real robot dog — on a real classroom budget.
Class 8 to 12 — Scratch, MicroPython, sensors, AI vision, LEGO extension. CBSE, ICSE, IB atelier programmes and coding clubs.
College robotics clubs, maker-spaces, hackathon kits — a hackable, portable quadruped for teams to iterate on all night.
Balance-beam events, obstacle courses, AI-vision navigation, gait races — a competition-ready quadruped that fits in a competition backpack.
Tech-curious kids, parents who code, engineers who miss LEGO — a serious robot dog that fits on the desk and speaks three languages.
The Standard Kit is the base MechDog — ESP32 controller, 8 coreless servos, ultrasonic sensor, three-language programming. The Advanced Kit adds the ESP32-S3 AI vision module (2 MP camera, browser streaming, face / colour / line vision), plus a touch sensor, light sensor, dot-matrix display and MP3 module for a fuller sensor curriculum. Same dog, extra brain and senses.
Yes — Scratch, Python (MicroPython) and Arduino (C/C++) all run on the same hardware. You switch between them via a firmware flash. Beginners start in Scratch, middle-schoolers write MicroPython, advanced students go to Arduino for direct servo-bus control. One robot, three learning stages.
Recommended age 12+. That said, a 9-10 year old can operate MechDog through the Wonderbot app’s 16 preset actions and Scratch blocks with adult supervision. Serious programming (MicroPython / Arduino) is comfortable from Class 8 upwards.
On-device. The ESP32-S3 AI vision module runs colour recognition, CNN face detection, colour tracking and line following locally — nothing is sent to the cloud, no OpenAI key required. Video streams to any browser on your local WiFi via a URL, or via the MechDog’s own AP hotspot.
Yes. The aluminium body has LEGO Technic-compatible mounting holes so you can extend MechDog with LEGO beams, decorative bricks or full LEGO builds. Combined with the touch / light / MP3 expansion modules, MechDog turns into a very flexible maker platform.
Yes — bulk pricing for schools and colleges, GST invoicing at ₹ 43,220 excl. GST, No-Cost EMI from ₹ 4,803/month across 9 months (via Snapmint at checkout), GeM listing where required, and government-tender documentation. Ask for the education price sheet on enquiry.
Manufacturer warranty plus the 1-Year xBoom AMC. Every order ships with remote onboarding, a “first-walk” setup call, and access to Scratch / Python / Arduino tutorials. Pan-India insured shipping. On-site workshops for schools and clubs available on request.
