The CrumbleBot XL 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


  • 8 Super-bright RGB LEDs - 'Sparkles'
  • 2 push-button switches
  • Easy to use Buzzer
  • Integrated pen holder
  • Robust connections for front sensors (eg. ultrasonic)
  • 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
  • Powered front accessory connector
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
  • Draw shapes such as squares, triangles and circles by moving the correct distances and directions
