WalkerBot is a 20-lesson build course for a real four-legged robot that walks and talks. It is written for someone who has never soldered or programmed: every part is named with the search keyword to buy it, every wire is shown on one diagram, and the Arduino code is tested and included in full.
Parents and kids looking for a weekend project that actually does something, teachers and maker-club organisers, and anyone who learns better from building than from a lecture. No 3D printer or workshop is required - a $35-60 parts list and a spare weekend is enough. Buying a kit is fine too: the course tells you the search keywords and what to check before you pay.
No. The course starts by explaining what a servo is, then walks through installing the Arduino IDE, uploading a test program and reading the code line by line. Every block of code is explained where it is used.
About US$35-60 in parts, depending on where you buy and whether you use a kit. The parts table gives the model, the quantity, a rough price and the exact search keyword for every line.
Most people finish assembly, walking and voice in one weekend, then add Bluetooth and obstacle avoidance on later evenings. Lessons are short, and each one ends with a homework you can test straight away.
No. Any four-leg chassis works: an acrylic kit, a robot kit you already own, cardboard and hot glue while you prototype, or a 3D print if you have one. The course shows what actually matters - where the servos sit and how the legs are fixed.
No. The build is the same anywhere and parts are sourced from Amazon, AliExpress or Taobao. Prices are shown in US dollars.
It names common part numbers only so you can find them - SG90, DFPlayer Mini, HC-05, HC-SR04. Specifications change, so check the listing before you buy.
The remaining 15 lessons, including walking, voice, Bluetooth and obstacle avoidance; the 12-question quiz with a printable certificate; and the printable parts, power and filming checklists.
Progress is saved on your own device and the whole course is cached for offline use at the workbench. Nothing you read or answer is uploaded anywhere. No soldering is required.
