4tronix Micro:bit Robobit Mk3 Buggy, Expansion board, micro:bit, Svart, Gult

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, sich as the new BitFace, 5x5 FireLed Matrix and OLED.

The Robobit Makecode package supports all versions of the Robobit Buggy

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

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
