    Ultimate Crumble Starter Kit

    The Crumble is a cheap, easy-to-use electronics controller. A few ‘croc’ leads and a USB cable are all you need to connect motors, LEDs and sensors and begin experimenting. No programming experience is required as the FREE software is a graphical, drag-and-drop system inspired by MIT Scratch.

    Crumble Getting Started Guide

    The Crumble is an easy-to-use programmable controller. It can drive 2 motors forwards and backwards at variable speeds. It has 4 IO (Input/Output) pads which allow connections to switches, LDRs, low power LEDs and so on.

    Basic Connections

    The Crumble has been designed to encourage tinkering, using ‘croc leads’ for quick and simple connections. Pads allow terminal blocks to be fitted or a direct solder connection made, while the larger 4mm holes make an easy target for conductive thread and needle.

    Crumble with croc leads

    The Crumble software runs on PC, Mac and, in the near future, Linux (including the Raspberry Pi). Inspired by MIT Scratch, programs are simply built by snapping blocks together on screen. Sending a program to the Crumble is almost instant, allowing rapid experimentation.

    The Crumble can be extended with digitally controlled full-colour LED, called Sparkles. Additionally, several expansions board (Crumbs) are also in the works.

  • CrumbleBot Mk2 Robot for Crumble (CrumBot2) (CRMBOT2)
    CrumbleBot Mk2 Robot for Crumble Adventures and Experiments

    The CrumbleBot Mk2 is an ideal way to introduce young (and old) children to robotics using the fantastic Crumble controller.

    All programming with the Crumble is extremely easy: drag, drop and click is all that is required to accomplish hundreds of simple and more complex tasks

    CrumbleBot Mk2 builds on the success of the Mk1 with lots more features:
    • 8 Super-bright RGB LEDs - 'Sparkles'
    • 2 push-button switches
    • Easy to use Buzzer
    • Simple jumper connection system - removes the need for croc clips
    • "Wire-free", low-profile battery holder (no USB connectors or wires to get broken)
    • Modified motor mounting positions to reduce dust ingress into the gearbox
    • Improved, smooth-running, front caster
    • Powered front accessory connector
    • Additional mounting holes near rear to allow fitting of a "second deck"

    With this robot kit you can do experiments for:
    • Basic movements (forward, reverse, left spin, right spin)
    • More complex turns (by moving one motor slower than the other)
    • Line following using the built-in line sensors with indicators
    • Light seeking or light avoiding using the built-in light sensors
    • Using the built-in Sparkles to give indications of what is happening
    • Use the built-in push-button switches to start/stop the program, change mode or anything else you want

    Simple programs to accomplish line following and light seeking are shown in the pictures for the listing.

    Crumble controller is NOT included unless option is selected

    Optional Addons available:
    • Ultrasonic distance sensor - simply screws on to the front powered accessory connector
    • Pen holder (with or without "halo" LEDs)
