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
