From the [micro:bit|https://en.wikipedia.org/wiki/Micro_Bit] page on Wikipedia:
%%blockquote
The __Micro Bit__ (also referred to as __BBC Micro Bit__, stylized as __micro:bit__) is an open source hardware ARM-based embedded system designed by the [BBC|https://en.wikipedia.org/wiki/BBC] for use in computer education in the UK.
The device is described as half the size of a credit card and has an [ARM Cortex-M0|https://en.wikipedia.org/wiki/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 form part of a larger 25-pin edge connector.
%%
The micro:bit can be programmed in [Microsoft MakeCode|https://www.microsoft.com/en-us/makecode] (a graphical language), [Python], and [Scratch|https://scratch.mit.edu/].
The micro:bit is available from many vendors, and it clearly makes sense to shop for the best value (and the best value based on currency). Some options:
* [micro:bit|https://shop.pimoroni.com/products/microbit] £13.50 from Pimoroni
* [BBC micro:bit|https://www.adafruit.com/product/3530] US$14.95 from Adafruit
* [BBC micro:bit Go Bundle|https://www.adafruit.com/product/3362] US$17.50 (with USB cable, battery pack and 2x batteries) also from Adafruit
* [BBC Micro:Bit in Gift Box (Microbit)|https://shop.4tronix.co.uk/collections/bbc-micro-bit/products/bbc-micro-bit-in-gift-box-microbit] £11.75 from 4Tronix

!! Available micro:bit Robots
Generally, unless stated otherwise the micro:bit board is __not included__ with the robot kits.
! M.A.R.S. Rover Robot for Microbit or Pi Zero
[{Image src='attach/microbit/MARS-robot.png' link='attach/microbit/MARS-robot.png' caption='The M.A.R.S. Rover (click to enlarge)' width='300' align='right' class='imgFloatRight'}]
* [M.A.R.S. Rover Robot for Microbit or Pi Zero|https://shop.4tronix.co.uk/collections/bbc-micro-bit/products/marsrover] £100.00
The 4tronix M.A.R.S. Rover is loosely based on the Curiosity and Mars 2020 rovers from NASA/JPL. It uses the same rocker arm, bogey and differential arm mechanism.
This is by far the most complicated micro:bit based robot available, and is certainly
not an entry-level robot. This uses six micro metal gear motors and four servos.
It's included in the list here so you can see that a micro:bit robot need not be limited by any notion of the simplicity of its controller. You can purchase the rover for use with a Raspberry Pi Zero or a micro:bit (not included).
! Waveshare Alphabot
[{Image src='attach/microbit/waveshare-alphabot2.jpg' link='attach/microbit/waveshare-alphabot2.jpg' caption='The Waveshare AlphaBot2 (click to enlarge)' width='250' align='right' class='imgFloatRight'}]
* [Waveshare AlphaBot2 2WD Platform Kit for BBC micro:bit|https://www.robotshop.com/en/waveshare-alphabot2-2wd-platform-kit-bbc-microbit-no-microbit.html] US$63.99
The __Waveshare AlphaBot2 2WD Platform Kit for BBC micro:bit (no micro:bit)__ is designed to use with the BBC micro:bit. It features rich common robot functions including line tracking, infrared obstacle avoiding, ultrasonic ranging, Bluetooth/2.4G remote control, etc.
This robot is not as pretty as some of the others (no rainbow flashing LEDs) but is probably one of the more advanced, durable and better-designed of the micro:bit robots. It is also available for [Arduino] and [Raspberry Pi].

! micro:Maqueen Plus
[{Image src='attach/microbit/maqueen_plus.jpg' caption='Maqueen Plus' align='right' width='230' class='imgFloatRight'}]
* [micro: Maqueen Plus|https://www.dfrobot.com/product-2029.html] US$49.90
__micro: Maqueen Plus__ is an advanced version of micro:Maqueen Lite (4.0), which is more powerful and intelligent. Optimized with better power management and larger capacity power supply, it can be perfectly compatible with [HuskyLens AI Vision Sensor|https://www.dfrobot.com/product-1922.html] which makes it an accessible AI robot teaching tool.
In addition, micro:Maqueen Plus comes with a larger and more stable chassis, more built-in functions and more expansion ports, it is not only suitable for classroom teaching, but also can be suitable for after-school extended exercises and robot competitions.
There are also expansion kits available which add mechanical actuators (like grippers), a gamepad controller, and a HuskyLens (AI camera).

Maqueen is a graphical programming robot for STEM education, which inherits playability and simple operation of micro:bit.
Maqueen is accessible to the Mind+ Programming platform now. Mind+ is a Scratch3.0-based graphical programming platform from DFRobot, supporting python, Arduino and other programming platforms. At present, Mind+ has been applied to all kinds of sensors, modules and related educational products.
! Bit:Bot
[{Image src='attach/microbit/bitbot..jpg' caption='Bit:Bot' align='right' width='250' class='imgFloatRight'}]
* [4Tronix Bit:Bot|https://shop.pimoroni.com/products/bit-bot] £39.90
This (almost) ready-assembled robot requires no soldering, no wires and nothing more than a screwdriver to complete it.
The Bit:Bot fully engages children and adults alike, allowing you to explore and code the micro:bit using any of the languages available (not all features are supported in all languages).
It appears the Bit:Bot may be replaced by the Bit:Bot XL, as the former no longer appears on the 4Tronix website (though it is still available from some vendors).
! Bit:Bot XL
[{Image src='attach/microbit/bitbot_xl.jpg' caption='Bit:Bot XL' align='right' width='250' class='imgFloatRight'}]
* [4tronix Bit:Bot XL Robot for BBC Micro:Bit|https://shop.4tronix.co.uk/collections/bbc-micro-bit/products/bitbotxl] £35.00
Introducing BitBot XL, taking the much-loved BitBot to the next level. We have made several changes, some subtle, some not so subtle, to give a much-improved experience of using and working with the BitBot.
The Microsoft Makecode Extension for Bit:Bot also works for BitBot XL. It can automatically detect while running which version you have, or you can force it to be the Classic BitBot or the new XL.
! MiniBit
[{Image src='attach/microbit/minibit.jpg' caption='minibit' align='right' width='250' class='imgFloatRight'}]
* [Minibit Robot for BBC Micro:Bit|https://shop.4tronix.co.uk/collections/minibit/products/minibit] £20.80
The Minibit is the younger sibling of the popular and well-loved Bit:Bot. It comes ready-built (wheels need pushing on).
A Makecode extension is available. Blocks available for driving the motors, LEDs and optional ultrasonic sensor and line follower module as well as the other plugin breakouts.
! :MOVE Mini
[{Image src='attach/microbit/move-mini-mk-2.jpg' caption=':MOVE Mini MK2' align='right' width='250' class='imgFloatRight'}]
* [:MOVE mini MK2 buggy kit|https://shop.pimoroni.com/products/move-mini-mk2-buggy-kit] £27.60
The Kitronik :MOVE mini MK 2 buggy robot kit for the BBC micro:bit is the latest version of the ever popular :MOVE mini that provides a fun introduction to robotics.
! Robot:bit MK3
[{Image src='attach/microbit/robotbitmk3_buggy..jpg' caption='Robot:bit MK3' align='right' width='250' class='imgFloatRight'}]
* [Robo:Bit Mk3 Buggy for the BBC Micro:Bit (v 1.3)|https://shop.4tronix.co.uk/collections/robobit/products/robo-bit-mk3] £32.00
Version 1.3 of this popular kit now uses a removable ultrasonic sensor, that uses the same connector as used on the Minibit and BitBot XL. This allows the use of alternative addons, such as the new BitFace, 5x5 FireLed Matrix and OLED.
! Adafruit CRICKET for micro:bit
[{Image src='attach/microbit/adafruit_crickit.jpg' link='attach/microbit/adafruit_crickit.jpg' caption='Adafruit CRICKET for micro:bit (click to enlarge)' width='250' align='right' class='imgFloatRight'}]
* [Adafruit CRICKIT for micro:bit|https://www.adafruit.com/product/3928] US$29.95
This isn't a robot in itself, but provides a powerful platform for building your own robot. You would choose your own chassis, motors (e.g., micro metal gear motors) and wheels.
Plug your micro:bit into the 40 pin edge connector and start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends micro:bit so you can still use all the goodies on the micro:bit, but now you have a robotics playground as well.
This is similar to the Adafruit Crickit used on the [KC01] robot (which uses a [Raspberry Pi] rather than a micro:bit).
