Robo:Bit Mk3 DIY Buggy for the BBC Micro:Bit (v1.2)

NB. BBC Micro:Bit is NOT included. Purchase >Here< if required

As we are now shipping v1.3 of this popular robot we have reduced the price of the few remaining v1.2 models. The v1.3 has a removable ultrasonic sensor using the same connector as the Minibit and BitBot XL (also a different front castor). Otherwise they are identical.

The Robobit Makecode package supports all versions of Robobit Mk3

This little buggy can be assembled very quickly using only a screwdriver. No soldering is required

The Mk2 here is still produced and will be a cheaper option if you don’t need all the sensors and extras of the Mk3.

Mk3 changes:

  • Integrated line following sensors
  • Integrated ultrasonic distance sensor
  • Integrated pen holder mounted at the axis of rotation
  • Integrated 8 element LED bar (WS2812 FireLeds) with “auto scanner” software support
  • Motors fitted on top to make it more compact
  • Screwdriver and Spanner widget tools included

 

Contents:

  • Robo:Bit Mk3 robotics controller PCB
  • Battery holder PCB
  • Fixings pack (motor mounts, screws, mounting pillars, caster, etc.)
  • 2 x Yellow Wheels with Tyres
  • 2 x Motors with pre-fitted connection wires (no soldering required)
  • Screwdriver and spanner widget

Using this great kit you can learn about:

  • Controlling motors with simple Forwards / Reverse controls
  • Controlling the speed of motors in both directions using PWM
  • Use a second BBC micro:bit with the easy-to-use radio software to control the buggy
  • Use the motion sensor on the micro:bit to detect collision with obstacles and avoid them
  • Detect when obstacles get close and change the program to avoid the obstacles
  • "Follow-Me" program that tries to stay a certain distance from the object in front
  • Use the 2 line sensors either side of the non-reflective line to detect the line and keep the buggy on track
  • Write more complex programs that behave as required if you meet a T-Junction or crossing of lines
  • Compare different line following strategies - create a race-track and see which strategy is fastest
  • In combination with the distance sensor, make it avoid obstacles on the track and then re-acquire the line
