Lesson 5 – Follow Me Tobbie

Study Videos –

Tutorial –

  1. As part of this tutorial we will work on validating the assembly of Tobbie II the robot.
  2. We will be using the MakeCode editor for purposes of programming. Head over to the MakeCode website – <Link>
  3. Once you have the MakeCode editor open you will need to add the “Tobbie II” micro:bit extension. See documentation here. – <Link>
  4. Click here to access the tutorial – <Tutorial Link> and download the code here – <Hex File> (Import using MakeCode)

Hardware Prerequisites –

  1. BBC micro:bit –
    1. This development track makes extensive use of the BBC micro:bit.
    2. If you haven’t purchased a BBC micro:bit yet you might want to head over to OzToyLib and pick one up now.
    3. We would recommend that you pick up the BBC micro:bit kit which comes with a battery pack, usb cable and the real micro:bit.
    4. We will be using the official online python editor to write code for all our tutorials. No investment required here.
  2. Wearable Kit –
    1. You will need a Tobbie II robot for BBC micro:bit.
    2. You can pick one up from OzToyLib.
  3. You can also look up each of these products at your local electronics hobby store.

About Tobie II Robot –

Tobbie II is a hexiped robot that can walk, sing, dance, follow, light up in different colors and do much more. Tobbie II is based on the BBC micro:bit and can be put easily assembled from the parts provided. With Tobbie II you can translate your creativity into a variety of projects and activities. The possibilities are truly endless !!! All the benefits of the dynamic micro:bit have been integrated into the Tobbie II Robot. Tobbie II is a build-it-yourself hexiped robot with a 360 degree free-rotation body. The Tobbie II kit includes all the electronic components, a motor and an IR sensor which can be used to create interactive projects. Tobbie II and micro:bit are an ideal combination to introduce you to the world of coding. You will program with ease in Javascript Blocks Editor or Python Editor (for more advanced coders) on your computer, laptop, smartphone or tablet.

About BBC micro:bit –

The Micro Bit (also referred to as BBC Micro Bit, stylised as micro:bit) is an ARM-based embedded system designed by the BBC for use in computer education in the UK. The board is 4 cm × 5 cm and has an ARM Cortex-M0 processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that are part of the 23-pin edge connector at the bottom of the board. The micro:bit can be programmed using the Microsoft Block code program editor which is similar to the block based language Scratch ideal for 7-12 year olds. The micro:bit can also be programmed using the Makecode editor in Javascript and Python which allows for older kids to learn the Javascript and Python programming language using the micro:bit.

This development track makes extensive use of the BBC micro:bit. If you haven’t purchased a BBC micro:bit yet you might want to head over to OzToyLib and pick one up now.

You can read more about the BBC micro:bit at the microbit website. Also see Kitronik’s resources here – Parents Complete Guide To The BBC micro:bit.

    How to use the hex file


    Hi, If I use the hex file does that mean that I won’t need to code to get my Tobbie II to follow me? I tried to import the hex code but then I’m unsure what to do with it and how it’ s beneficial. Any help would be greatly appreciated.

      Hi mate,

      The hex file is basically a copy of the entire program. If you are keen to learn how to program the robot then it’s best that you follow the relevant tutorials on the page. You should see a link for a tutorial on every page.

      The link to the hex file is provided if you just want to copy the program to your BBC micro:bit and skip writing the code. This however defeats the purpose of purchasing the robot in the first place. Either ways it’s up-to you.

      If you are keen to learn more about the micro:bit or work out how to copy the hex file onto the BBC micro:bit then check out the first tutorial of the track and see the links provided – https://learning.kidzcancode.com/lesson/lesson-1-introduction-to-the-bbc-microbit-20/

      Happy hacking and let us know if you have any questions.
