Programming Construction Series No.1

MICROCOMPUTER ROBOT (CRAWLER TYPE)

*This product has now been updated with a newer version of the BBC micro:bit which has an additional audio sensor, plus a function whereby loud noises make it stop and give a comical reaction.

This assembly kit creates a crawler robot that runs using a BBC micro:bit microcomputer, ultrasonic sensor and motor driver circuit. When the ultrasonic sensor identifies an obstacle ahead, it transmits that information to the BBC micro:bit, which uses a pre-installed program to give the motors commands to avoid the obstacle. Separately sold parts can be used to control the robot remotely, and the BBC micro:bit can be coded with original programs via computer, too.

A Great Intro to Coding!
The included BBC micro:bit has a program pre-installed, meaning you can play with the robot once you have assembled it and got your batteries. With the use of a computer, the BBC micro:bit can additionally be coded to perform a range of actions defined by you - the free online MakeCode editor is a great tool for doing so! It uses intuitive visual programming, where you combine different individual commands in blocks to achieve your final program. For those who wish to, a second BBC micro:bit (sold separately) can be used as a remote controller.
