The motor:bit Smart Car Kit is a two-wheel robot students build themselves, then teach to see. With an ultrasonic sensor at the front and two line-tracking modules underneath, it can park at a fixed distance, hold its position behind a moving obstacle, or follow a taped line around the classroom floor.
What's included:
motor:bit driver board with a TB6612 chip, 12 GVS ports and an I2C port
sonar:bit ultrasonic distance sensor
Two line-tracking modules
Acrylic chassis and assembly hardware
micro:bit board and batteries are not included — add a micro:bit V2 at checkout
What students practise:
Using sensor input to make a decision, rather than just running a fixed sequence
Threshold thinking — deciding what counts as "too close" or "off the line"
Building and wiring a working machine from parts
Debugging behaviour they can watch happen
Six documented projects on the ElecFreaks wiki take a class from fixed parking through line tracking to Bluetooth remote control, so the same car supports several lessons rather than one.

The Ring:bit Car v2 is the gentlest way into micro:bit robotics. Students assemble it in a few minutes, slot in a micro:bit, and have a car they can program to drive a square, follow a light, or glow in rainbow colours. It is small, cheap enough to buy in numbers, and forgiving of mistakes.
What's included:
Ring:bit v2 expansion board, which breaks out three of the micro:bit's GPIO ports
Two 360° continuous rotation servos and a car chassis
Rainbow LED module with eight full-colour LEDs
Assembly guide, with build and code walkthroughs on the ElecFreaks wiki
micro:bit board and batteries are not included — add a micro:bit V2 at checkout
What students practise:
Sequencing: getting a robot to do the right things in the right order
Measuring and adjusting — a square that doesn't close teaches more than one that does
Block coding in MakeCode, with Python sample code available for older students
Simple mechanical assembly and troubleshooting
Expansion modules for line following, obstacle avoidance and drawing are sold separately, so the same car can carry a class from first program to independent project work.
