The Handy Bug (or a robot very close to it!) can be built using the following LEGO sets:

  • Technology Resource Set W979649, about $79
  • 9-Volt Motor with Gear Reduction W775225, about $18 each (you need two of them)
  • 9-Volt Touch Sensor and Leads W779911, about $18 each (you need two of them)

    •  

    To make adapters from the LEGO connectors to the Handy Board, you'll need 0.1" header pins, Digi-Key part number 929400-01-36-ND, about $2 each. Each item has 36 pins, enough for 9 Handy Board sensor plugs or 12 Handy Board motor plugs.

    Also, Gleason Research has a sensor/motor kit that is a very good value.
