Robo:Bit Mk3 Buggy For The Micro:bit

The Robo:Bit Mk3 Buggy is a fantastic robot buggy kit for the

BBC micro:bit

, and an exciting way to learn how to code.

Kit includes

• A PCB chassis (with integrated line sensors and pen holder!)
• Motors
• Wheels
• Ultrasonic sensor
• Battery holder
• Fixings

Just

add a micro:bit

and

4x AA batteries

 to start building your robot! This little buggy can be assembled very quickly using only the included screwdriver. No soldering is required!

Breakout Compatability

Compatible with the

Ultrasonic Distance Sensor

,

OLED

and

FireLED 5×5 Matrix

breakouts!

The ultimate learning kit

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
