Assembly Guide¶
This guide will walk you through the assembly process of the walking robot. The assembly consists of three main parts:
- Mechanical Assembly: This includes all the physical components like motors, legs, main board, and the remote control.
- Programming: This covers the software setup for both the robot and remote control using Micro:bit.
- Testing and Calibration: This section guides you through testing the assembled robot and calibrating its movements for optimal performance.
Let's get started with the mechanical assembly first.

2. Programming¶
You will be using Microsoft MakeCode in this section.
- It can be access via https://makecode.microbit.org/#
- You will need to sign up for an account
Once you have got an account, please go to the next steps.
2.1 Basic Micro:bit programming using MakeCode¶
- Click on "Import" button
- Choose "Import URL"
3. Open project URL, enter: https://github.com/beets3d/b3d1-walking-bot-main
** Please note: ** if you are using more than one walking robot. You should assign unique number to "radio set group". The group number can be any value from 0 to 255. Remember to change that in remote control in the next section as well.
- Plug in your micro:bit using a USB cable, and Click "Download
2.2 Remote control setup¶
Repeat the above, using this project URL: https://github.com/beets3d/b3d1-walking-bot-controller
3. Testing and calibration¶
