Robo:Bit Mk2 Buggy for the BBC Micro:Bit (RoboBit for Microbit)

Robo:Bit Mk2 DIY Buggy for the BBC Micro:Bit

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

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

Improvements over Mk1:

• Stronger motor sub-chassis with no structural solder joints
• Wire-free battery pack
• Easier to attach battery holder
• Current limit on motors to prevent stall current resetting the Micro:Bit
• Solid bolt-on ultrasonic attachment

Contents:

• Robo:Bit robotics controller PCB
• Fixings pack (battery holder, screws, mounting pillars, caster, etc.)
• 2 x Yellow Wheels with Tyres
• 2 x Motors with pre-fitted connection wires (no soldering required)

Optional extra: Line sensor pack
Optional extra: Ultrasonic distance sensor module

Using the basic 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
